peaka-mcp-server

List all projects accessible with the current API key. For Partner API keys, enumerates projects across all organizations and workspaces. For Project API keys, returns the single project bound to the key.

Query question/sql pairs from Peaka's golden sql vector store. If an existing query matches the user's question, it can be reused directly.

Runs the given sql query on Peaka.

Get metadata for all catalogs, schemas, and tables in the Peaka project in a single call. Optionally filter by `catalogId` and/or `schemaName`.

List all available catalogs in the Peaka project. Returns catalog names, types, and connection info.

List all available schemas for a given catalog in the Peaka project.

List all available tables for a given catalog and schema in the Peaka project.

List all columns for a given table in the Peaka project. Returns column names, data types, and constraints.

Get table relationships (foreign keys) for a catalog. Useful for constructing accurate JOINs.

Get column-level statistics for a table, including distinct-value fractions per column.

Create a cache for a table in the Peaka project. Caching a table improves query performance by storing the data locally.

Create caches for multiple tables in a single call. Preferred over repeated `peaka_create_cache` calls.

Get all cache statuses for tables in the Peaka project, including current caching state, execution history, and progress.

Trigger a full refresh on an existing cache.

Trigger an incremental update on an existing cache, fetching only new or changed rows.

Update cache settings (schedules) on an existing cache. Replaces both schedules entirely each call.

Delete an existing cache; the underlying table is not affected.

List all saved queries in the Peaka project. Returns query names, SQL content, and whether they are plain or materialized.

Read a single saved query by its ID. Returns the full query object including SQL, type, and the materialized-query refresh schedule.

Execute a saved query by its ID in the Peaka project.

Create a named, saved query in the project's semantic layer. Returns the created query including its ID. For materialized queries, accepts an optional `schedule` to set the auto-refresh cadence — `{type: "interval", repeatDuration: "PT6H"}`, `{type: "cron", cronExpression: "0 0 * * *", timezone: "UTC"}`, or `{type: "none"}` to disable.

Update an existing saved query's display name, SQL body, and/or auto-refresh `schedule` (interval, cron, or `{type: "none"}` to disable; materialized queries only).

Delete a saved query from the Peaka project.

Trigger a refresh on a materialized saved query. Use `peaka_list_queries` to find query IDs whose `queryType` is `MATERIALIZED`.

Inspect the auto-refresh state of materialized queries: last refresh status, last/next scheduled execution, and schedule settings. Pass a `queryId` for a single query or omit it to list all.

List all data source connections in the Peaka project, including each connection's id, name, and type.

Get connection-specific configuration detail for a data source connection.

Create a semantic catalog in the Peaka project. A semantic catalog groups semantic tables (saved queries surfaced as queryable tables) under a single namespace.

Create a semantic table inside a semantic catalog, backed by a saved query. Requires `catalogId`, `schemaName`, `tableName`, and `queryId`.

Delete a semantic table from a semantic catalog. The underlying saved query is not affected.

Refresh project metadata for a specific catalog. Long-running; triggers the refresh and polls for completion.

Check the current status of a metadata refresh job for a specific catalog.
