概要

What is Kodus OSV?

Kodus OSV is an HTTP MCP (Model Context Protocol) server that wraps the OSV v1 API for on‑demand open‑source vulnerability lookups. It exports MCP tools so AI agents can query the OSV vulnerability feed directly. The server uses a Streamable HTTP MCP endpoint and is intended for developers and security teams integrating vulnerability data into their MCP‑aware workflows.

How to use Kodus OSV?

Install dependencies with bun install, set environment variables (PORT, HOST, OSV_API_URL), and run bun run index.ts. The MCP endpoint is http://<host>:<port>/mcp. Clients can connect via Claude Code CLI (claude mcp add --transport http mcp-osv http://localhost:3000/mcp), VS Code (code --add-mcp), or the MCP Inspector.

Key features of Kodus OSV

  • Streamable HTTP MCP endpoint at /mcp
  • Two tools: osv_query (single) and osv_query_batch (multiple)
  • Configurable base URL via OSV_API_URL environment variable
  • Clear validation rules (commit XOR version, purl or name+ecosystem)
  • Supports pagination with pageToken field

Use cases of Kodus OSV

  • Query vulnerabilities for a specific package version (e.g., PyPI, npm)
  • Batch query multiple packages or commits in a single request
  • Perform commit‑based vulnerability lookups for Go or other ecosystems
  • Integrate real‑time OSV checks into MCP‑enabled IDEs or CLI agents

よくある質問

1

What runtime does Kodus OSV require?

Bun is required. No other runtime is supported according to the README.

2

How can I change the OSV API endpoint?

Set the `OSV_API_URL` environment variable. It defaults to `https://api.osv.dev/v1`.

3

What tools does Kodus OSV provide?

Two tools: `osv_query` for a single vulnerability query and `osv_query_batch` for multiple queries in one request.

4

What are the rules for the `package` parameter in queries?

You must use either a `purl` string or the combination of `name` and `ecosystem`. If you use `purl`, do not include the `@version` part; provide the version separately in the `version` field.

5

How can I debug the server or test the tools?

The server logs a confirmation message on startup. You can use `curl` with a JSON‑RPC initialize request or a `tools/list` call against the `/mcp` endpoint to see available tools.
