48Remove a subgraph from a variant and start composition, the same write that `rover subgraph delete` performs. Returns the composition errors that the removal causes. This deletes the subgraph from the variant and can break the running router. Set dryRun to true first: the response then reports the composition result that the removal would produce, including updatedGateway, and deletes nothing. Provide the graph ID, the variant name, and the subgraph name.
Assign a tag to a graph artifact, the same write that `rover graph-artifact tag` performs. If the tag does not exist, it is created. If it exists, it moves to this artifact, and any router that fetches by that tag receives the new artifact. Returns the artifact's ID and digest, or an error with a message. Provide the graph ID, the tag name, and the artifact digest.
Read the filter configuration of a contract variant: the tags it includes, the tags it excludes, the source variant it is built from, and a human-readable description of the configuration. This is the same read that `rover contract describe` performs. A contract variant is a filtered view of another variant's schema, built by including and excluding schema elements by tag. The filter configuration does not include whether unreachable types are hidden. The description states it, so read it there before you update a contract with PublishContract. A variant that is not a contract returns null for the filter configuration. Provide the graph ID and the contract variant name.
Traffic broken down by client for a graph over a time window, as compact CSV. Columns: start timestamp, end exclusive timestamp, client name, client version, operation name, request count, request latency p50 ms, request latency p99 ms, request with error count. Answers which clients call a graph, which client versions are still on the wire, and which client drives errors or latency. Clients that do not report `apollographql-client-name`/`-version` come back with empty name and version columns. Ranked by `orderBy` descending: default REQUEST_COUNT (busiest); REQUEST_WITH_ERROR_COUNT for most error-prone, REQUEST_LATENCY_P99_MS for slowest. `variantName` and `operationName` scope to one or more variants or operations by exact name (omit for all). Rows are one per client + version + operation, so a busy graph has far more groups than the other metrics tools: scope by `operationName` or raise `limit` when a breakdown looks truncated. Keep the default `resolution` of ENTIRE_RANGE for totals and top-N, which gives one row per group ranked over the whole window. DAY/HOUR/MINUTE give one row per group per bucket ranked within each bucket, so a window total then needs a per-group sum plus a `limit` big enough to cover every bucket; too small a `limit` silently undercounts. Only HOUR and MINUTE accept a `to` of now, so use them for bursts in the last 24 hours. Avoid MONTH: it labels buckets by calendar month, not by the requested window.
Create a schema proposal against a source variant, the same action as Create proposal in GraphOS Studio. GraphOS creates a proposal variant that starts as a copy of the source variant's schema, and the proposal starts in DRAFT. Returns the proposal variant's name and the new proposal's ID and status, or an error with a message. To add schema changes, call PublishProposalRevision next. Provide the graph ID, the title, and the source variant name. Optionally provide a description.
Approve or reject a revision of a schema proposal, with an optional comment, the same action as Review in GraphOS Studio. Only a requested reviewer can review, and calling this again replaces the caller's earlier review. Returns the proposal's status and its reviews, or an error with a message. Provide the graph ID, the proposal variant name and latestRevision.id from GetProposal, and the decision (APPROVED or NOT_APPROVED).
Save a new revision of a schema proposal by publishing changed subgraph schemas to its proposal variant, the same action as Save revision in GraphOS Studio. GraphOS composes the proposal variant, records the diff against the source variant, and runs schema checks on it. The source variant does not change. Send only the subgraphs that change, each with its full SDL. previousLaunchId must be the proposal variant's latest launch ID from GetProposal. If someone saved a revision since, the call fails, so read the proposal again before you retry. GraphOS saves the revision even when the schema does not compose, so this call succeeding does not mean the change is valid. Call GetProposal after the check finishes: latestRevision.checkWorkflow.status and latestRevision.launch.status show the result, and GetCheckResults takes the check ID for the details. Returns the proposal's new latest revision, or an error with a message. Provide the graph ID, the proposal variant name, previousLaunchId, a unique revision label, a summary of the change, and the subgraphs.
Top subgraphs/connectors by traffic/health for a graph over a time window, as compact CSV. Columns: start timestamp, end exclusive timestamp, fetch service name, fetch count, fetch latency p50 ms, fetch latency p99 ms, fetch with errors count. Ranked by `orderBy` descending: default FETCH_COUNT (busiest); FETCH_WITH_ERRORS_COUNT for most error-prone, FETCH_LATENCY_P99_MS for slowest. `variantName` scopes to one or more variants (omit for all). `subgraphName` scopes to one or more subgraphs by exact name (omit for all); pattern/substring matching is not supported. `clients` scopes to the fetches driven by one or more clients; omit `clientVersion` to match every version of that client, and use GetClientMetrics to discover the names a graph sees. Keep the default `resolution` of ENTIRE_RANGE for totals and top-N, which gives one row per subgraph ranked over the whole window. DAY/HOUR/MINUTE give one row per subgraph per bucket ranked within each bucket, so a window total then needs a per-subgraph sum plus a `limit` big enough to cover every bucket; too small a `limit` silently undercounts. Only HOUR and MINUTE accept a `to` of now, so use them for bursts in the last 24 hours. Avoid MONTH: it labels buckets by calendar month, not by the requested window.
Fetch a graph artifact by its digest, the same lookup that `rover graph-artifact fetch --digest` performs. A graph artifact is the build output, such as the composed supergraph schema, that GraphOS Router fetches from Apollo's OCI registry. Returns the artifact's ID, digest, status (GRAPH_ARTIFACT_COMPLETED, GRAPH_ARTIFACT_PENDING, or GRAPH_ARTIFACT_FAILED), build errors, timestamps, variant, the launch that produced it, its registry URI, and the tags assigned to it. To find a digest from a tag name, use GetGraphArtifactTags. Provide the graph ID and the digest.
Returns the Apollo Connectors specification for guidance on creating or modifying GraphQL schemas that use @connect or @source.
Reads an Apollo documentation page by slug in chunks. Use slugs returned by ApolloDocsSearch.
Create or update a contract variant and start a launch for it, the same write that `rover contract publish` performs. A contract variant is a filtered view of another variant's schema, built by including and excluding schema elements by tag. The filter configuration replaces the previous one in full, so send the complete include and exclude lists rather than only the tags you want to change. The same applies to hideUnreachableTypes, which has no default: when you update a contract, pass the value it has now. GetContractConfig states that value in its description. Returns the contract variant and a link to the launch, or the error messages that stopped it. Provide the graph ID, the contract variant name, the source variant, the include and exclude tag lists, and whether to hide unreachable types.
Delete an API key from an organization, the same write that `rover api-key delete` performs. This cannot be undone, and every client that uses the key stops authenticating. Returns the deleted key's ID. Provide the organization ID and the key ID, which GetApiKeys returns.
List past schema checks for a graph: each check's ID, status, timestamps, the subgraph it checked, the variant it ran against, the commit, and the status of each task in the check, plus the total count for the filter. Use this to find a check, then pass its ID to GetCheckResults for failure details. Provide the graph ID. Optionally filter by status (PASSED, FAILED, PENDING), subgraph names, branches, variants, authors, or check IDs, and page with limit and offset.
Validate client GraphQL operations against a variant's published schema and return each problem's type (FAILURE, WARNING, INVALID), code, description, and the name of the operation it came from. This is the same check that `rover client check` runs. Nothing is published and no state changes. Provide the graph ID and the operations, each one a body and an optional name. Optionally name the variant to validate against; the default is "current".
Read one schema proposal by its ID: title, description, status, author, the source variant, and the proposal variant with the ID of its latest launch. Also returns the latest revision (its ID, summary, schema check, and launch), every review with its decision and comment, and whether the source variant changed since the proposal was created. The write tools for a proposal take the graph ID and the proposal variant name from this response. ReviewProposal and AddProposalComment take latestRevision.id, and PublishProposalRevision takes backingVariant.latestLaunch.id as previousLaunchId. Provide the proposal ID, which GetProposals returns.
Resolve the caller's identity from their API key or OAuth token. Call this FIRST when the user asks about "my graph" but has not provided a graph ID. For a graph/service key, `me` resolves to a Graph: use `id` as the graphId and `variants[].name` as the variant for the graph-scoped health-check tools, so the user does not have to supply either. For a user (personal key or OAuth), `me` resolves to a User instead: there's no single graph, so each org membership's `graphs[].id` / `graphs[].variants[].name` lists the graphId/variant options the graph-scoped tools need, across every org the user belongs to. Also handles service-account keys.
List the graph artifact tags on a graph and the artifact each tag points to: the artifact's ID, digest, status, creation time, and variant. GraphOS Router can fetch an artifact by tag name instead of by digest. It is similar to `rover graph-artifact list-tags`, which filters by artifact digest instead of variant. Use it to find a tag or a digest before you call GetGraphArtifact, TagGraphArtifact, or UntagGraphArtifact. Provide the graph ID. Optionally filter by variant name, and page with first (at most 20) and after.
List the API keys and client-credential pairs of an organization. For each key: its ID, name, type, creation, expiry, last use, revocation time, and the resources it can access. For each client-credential pair (an OAuth client that authenticates with the client credentials grant): its client ID, name, creation time, creator, grant types, scopes, and the resources it can access. Key values and client secrets are never returned. Pass a key's ID to RenameApiKey or DeleteApiKey. Those tools do not work on pairs, so manage pairs in GraphOS Studio or with `rover api-key`. Provide the organization ID, which GetMyIdentity returns. Optionally filter keys by status (ACTIVE by default, or ALL, EXPIRED, REVOKED) and type (OPERATOR, SUBGRAPH, VARIANT, GATEWAY, SCIM). The filters do not apply to pairs. The two lists page separately: page keys with first and after, and pairs with pairsFirst and pairsAfter.
Publish a schema to a graph variant, the same write that `rover graph publish` performs. Use this for a monograph; use PublishSubgraph for one subgraph of a federated graph. Returns a result code, whether the publish succeeded, a human-readable message, and the hash of the published schema. This changes the schema registry and can change what clients see. Run RunSchemaCheck first to see the effect on client operations. Provide the graph ID, the variant name, and the schema as SDL. Optionally provide the git branch and commit to label the publication.
List the schema proposals on a graph: each proposal's ID, title, status (DRAFT, OPEN, APPROVED, IMPLEMENTED, CLOSED), timestamps, author, the source variant it proposes changes to, and the proposal variant that holds its changes, plus the total count for the filter. A schema proposal is a reviewable set of schema changes that GraphOS stores on its own variant. Pass a proposal's id to GetProposal for its revisions and reviews. Provide the graph ID. Optionally filter by status, source variant names, or subgraph names, and page with limit and offset.
Searches official Apollo documentation for GraphQL, GraphOS, Apollo Router, Apollo Client, MCP Server, schema design, deployment, and Connectors. Returns URLs, slugs, and excerpts.
Fetch the offline Enterprise license for the organization that owns a graph, the same data that `rover license fetch` returns. The license is a signed JWT that lets GraphOS Router enable Enterprise features while it runs disconnected from GraphOS. Returns null when the organization does not have offline licenses enabled, which requires a request to Apollo. Provide the graph ID.
Retrieve schema lint violations from a graph's most recent schema checks: each diagnostic's coordinate, severity level, message, rule, and source location, plus error/warning/total/ignored counts. Use to assess schema quality and naming/best-practice violations. Provide the graph ID and optionally a limit (default 5 most recent schema checks).
Delete a graph artifact tag from a graph, the same write that `rover graph-artifact untag` performs. The tag and its full history are removed, and any router that fetches by that tag can no longer resolve it. The artifact itself stays. Tags that Apollo manages, such as a variant's latest tag, cannot be deleted. Returns the deleted tag name, or an error with a message. Provide the graph ID and the tag name.
Read the schema (SDL) that is currently published to a graph variant, with its hash and publication time. This is the same read that `rover graph fetch` performs. The response holds the whole document and is not truncated. A large federated graph measured over 800,000 characters, roughly 200,000 tokens, which exceeds the context window of most models. Prefer GetSubgraphSchema, which reads one subgraph at a time, and use this tool only when you need the whole API schema. Provide the graph ID and the variant name.
Change the status of a schema proposal, the same action as the status menu in GraphOS Studio. DRAFT is for work in progress, OPEN asks reviewers to review, and CLOSED abandons the proposal. GraphOS accepts APPROVED only when the proposal has as many approvals as the graph requires, and it never accepts IMPLEMENTED from this tool. Both return a ValidationError that names the rule. Returns the proposal's ID and new status. Provide the graph ID, the proposal variant name from GetProposal, and the new status.
Read the composed supergraph schema (SDL) for a graph variant, with the composition ID and any composition errors. This is the same read that `rover supergraph fetch` performs. A supergraph schema is the single schema that composition builds from every subgraph, and it carries federation directives that the API schema does not. The response holds the whole document and is not truncated, and a supergraph schema is larger than the API schema it produces. Expect the same order of size: a large federated graph exceeds 800,000 characters, roughly 200,000 tokens. A variant that is not federated has no composition result, and the tool returns null for it rather than an empty document. Provide the graph ID and the variant name.
Top operations by usage/health for a graph over a time window, as compact CSV. Columns: start timestamp, end exclusive timestamp, operation name, request count, request latency p50 ms, request latency p99 ms, request with error count. Ranked by `orderBy` descending: default REQUEST_COUNT (busiest); REQUEST_WITH_ERROR_COUNT for most error-prone, REQUEST_LATENCY_P99_MS for slowest. `variantName` scopes to one or more variants (omit for all). `clients` scopes to one or more clients; omit `clientVersion` to match every version of that client, and use GetClientMetrics to discover the names a graph sees. Keep the default `resolution` of ENTIRE_RANGE for totals and top-N, which gives one row per operation ranked over the whole window. DAY/HOUR/MINUTE give one row per operation per bucket ranked within each bucket, so a window total then needs a per-operation sum plus a `limit` big enough to cover every bucket; too small a `limit` silently undercounts. Only HOUR and MINUTE accept a `to` of now, so use them for bursts in the last 24 hours. Avoid MONTH: it labels buckets by calendar month, not by the requested window.
Read the outcome of one schema check run: the overall status, and for each task in the run the composition errors, lint diagnostics, schema changes with the client operations they affect, downstream variant results, and custom check violations. Use this after GetSchemaChecks gives you a check ID. Provide the graph ID and the check ID. The affected operations are paged with affectedOperationsLimit and affectedOperationsOffset; the change list is capped by the server, and areChangesTruncated reports when that happened.
Retrieve recent launches for a graph variant (most recent first) to detect deployment instability such as repeated failures or frequent superseded launches. Each entry includes the launch id, status, and timestamps, so you can identify a specific launch and drill into it with GetLaunch. Use to assess deployment stability. Provide the graph ID, variant name, and optionally a limit (default 20 most recent launches, max 100 per page) and an offset to page further back.
Rename an API key in an organization, the same write that `rover api-key rename` performs. The key value and its access do not change. Returns the key's ID and new name. Provide the organization ID, the key ID, which GetApiKeys returns, and the new name.
Inspect the most recent launch for a graph variant: status, completion time, subgraph changes, composition errors, and a schema diff summary vs the previous launch (additions/removals/edits/deprecations plus affected operations). Use to assess schema composition health and the impact of recent schema changes. Also returns the latest approved launch for comparison. Provide the graph ID and variant name.
Check whether a graph variant has a Persisted Query List (PQL), and return its ID, its name, and its current build (revision and operation count). Pass the ID to PublishPersistedQueries. Use to assess PQL configuration — a production variant with no PQL is a security gap. Provide the graph ID and variant name.
Publish a subgraph schema to a variant and start composition, the same write that `rover subgraph publish` performs. Returns whether the subgraph was created or updated, any composition errors, and the launch that started. This changes the schema registry and can change what the router serves. Run RunSubgraphCheck first to see the effect on client operations. Provide the graph ID, the variant name, the subgraph name, and the schema as SDL. Provide the routing URL when you add a subgraph or move its endpoint. Optionally provide a revision label and the git branch and commit.
Retrieve metadata for a graph variant: its identifier, federation version, the URL of its GraphQL endpoint, and its subgraph inventory (names only). Use this to assess a variant's composition setup, such as subgraph inventory and federation version compliance. Provide the graph ID and variant name (e.g., "production").
Identify the most-used operations on a graph variant for a time range, with request counts, types, and signatures. Use to find high-traffic operations, detect unused operations, and prioritize findings by traffic impact. Provide graph ID, variant, and a from/to time range (ISO 8601 timestamps; `to` must be at least 6 hours before now), plus an optional limit (default 50). This report is rate limited.
Inspect a single launch by ID for full detail: status, timestamps, which subgraphs changed, composition errors, and the schema diff summary. Use to drill into a specific launch — e.g. a failed or superseded one found via GetLaunchHistory (pass its id here). Provide the graph ID, variant name, and launch ID.
Read one subgraph's published schema (SDL) from a variant, with its routing URL, revision, and last update time. This is the same read that `rover subgraph fetch` performs. Read one subgraph at a time: a whole supergraph document is much larger and can pass the token limit of the model. Provide the graph ID, the variant name, and the subgraph name. Use GetVariantDetails first if you do not know the subgraph names.
Start a schema check of a proposed schema against a variant, the same check that `rover graph check` starts. Use this for a monograph or for a whole supergraph schema; use RunSubgraphCheck for one subgraph. The check runs in the background, so this returns a workflow ID and a Studio URL, not a result. Pass the returned workflowID to GetCheckResults to read the outcome. Provide the graph ID, the variant name, and the proposed schema as SDL. Optionally provide the git branch and commit to label the run in Studio.
Read the README of a graph variant, with the time it was last updated and who updated it. This is the same read that `rover readme fetch` performs. The README is the Markdown document shown on the variant's page in GraphOS Studio. Provide the graph ID and the variant name.
Delete a graph, the same write that `rover graph delete` performs. This is a soft delete: the data is not removed permanently and Apollo support can restore the graph. Every variant of the graph stops serving, so confirm the graph ID with the user before you call this. Returns null on success. Provide the graph ID.
Lint a GraphQL schema document against the graph's lint rules and return each diagnostic's coordinate, severity level, message, rule, and source location, plus the error, warning, total, and ignored counts. This is the same check that `rover graph lint` and `rover subgraph lint` run. Nothing is published and no state changes. Provide the graph ID and the schema as SDL. Optionally provide baseSdl to report only the diagnostics that the new schema introduces against that base.
Create an API key for an organization. The response contains the new key's value in token. It is a live credential, so give it to the user to store in a secret manager, and do not repeat it, log it, or pass it to another tool. Which key types you can create depends on how you authenticate. With the GraphOS sign-in (OAuth), you can create OPERATOR, SCIM, and GATEWAY keys. SUBGRAPH and VARIANT keys need a personal API key in the x-api-key header. With an operator key in x-api-key, you can create only GATEWAY keys, and a graph key can create none. No credential can create ROUTER keys. OPERATOR, SCIM, and GATEWAY keys also require the Org Admin role. GATEWAY keys are used by Apollo Gateway instances. Choose the narrowest type that does the job, and confirm the type and its resources with the user before you call this tool. Provide the organization ID, the key name, and the type. For a SUBGRAPH key, list each graphId, variantName, and subgraphName in resources.subgraphs. For a VARIANT key, list each graphId and variantName in resources.variants.
Publish operations to a persisted query list, the same write that `rover persisted-queries publish` performs. A persisted query list is the set of operations a router accepts when it is configured to reject anything else. Operations you do not mention stay in the list unchanged: pass operations to add or replace entries, and remove to drop them. Returns the new revision and the total operation count, or reports that nothing changed. Use GetPersistedQueryListStatus to find the list ID and its current revision. Provide the graph ID and the persisted query list ID.
Start a schema check of one proposed subgraph schema against a variant, the same check that `rover subgraph check` starts. The check runs in the background, so this returns a workflow ID and a Studio URL, not a result. Pass the returned workflowID to GetCheckResults to read the outcome. Provide the graph ID, the variant name, the subgraph name, and the proposed subgraph schema as SDL. Optionally provide the git branch and commit to label the run in Studio.
Add a comment to a schema proposal, the same action as commenting in GraphOS Studio. With no other options, the comment is a general comment on the proposal. To comment on one change, pass the schema coordinate (for example Query.products) and the subgraph name as schemaScope. To reply, pass the parent comment's ID. Returns the new comment's ID and message, or an error with a message. Provide the graph ID, the proposal variant name and latestRevision.id from GetProposal, and the message.
Replace the README of a graph variant, the same write that `rover readme publish` performs. The README is the Markdown document shown on the variant's page in GraphOS Studio. The new text replaces the whole README, so read the current one with GetReadme first if you intend to keep any of it. Provide the graph ID, the variant name, and the full README text.
