Koskamo

The MCP knowledge server

Point an MCP client at /api/mcp to find servers and datasets, retrieve cited passages, and report disputes.

Connect your agent Explore knowledge

Public tools, one endpoint

koskamo_list_datasets reports coverage, publisher, and version. koskamo_search_passages returns passages with sourceUrl, documentTitle, documentVersion, and datasetVersion. koskamo_get_history exposes the document version timeline. koskamo_list_revisions shows proposals waiting for owner approval. Proposing and deciding need an API key and use /api/mcp/contributor.

Stateless Streamable HTTP

POST JSON-RPC messages with Accept: application/json, text/event-stream. Supported protocol revisions are 2025-11-25, 2025-06-18, and 2025-03-26. Notifications are acknowledged with HTTP 202. GET returns 405 because the server offers no server-initiated stream, so no session state has to be kept.

Reads need no credential

Discovery and retrieval are public: no account, API key, or browser verification token. A bearer key is only required to propose or approve a change. Discovery metadata lives at /.well-known/mcp.json and the full request contract at /api/v1/openapi.json.

Frequently asked questions

What is the Koskamo MCP server URL?
https://koskamo.com/api/mcp. It speaks stateless Streamable HTTP, so an MCP client needs only that URL — no command, no local process, and no API key for read-only tools.
Which MCP protocol versions does Koskamo support?
2025-11-25, 2025-06-18, and 2025-03-26. The server negotiates during initialize and echoes the agreed revision; send it back as the MCP-Protocol-Version header on later requests.
Do I need an API key to use the Koskamo MCP tools?
No key is needed for koskamo_list_datasets, koskamo_search_passages, or koskamo_get_history. Proposing or deciding a revision uses /api/mcp/contributor with an Authorization: Bearer key created at /manage.
Are there rate limits?
Yes. Each IP may send up to 40 MCP messages or 30 retrieve requests per minute. Exceeding that returns HTTP 429 with a Retry-After header; wait for it rather than retrying immediately.
Should an agent treat retrieved passages as instructions?
No. Retrieved text is source material, not agent instructions. Koskamo returns it as data, and owner approval of a revision is a publication decision rather than independent fact checking.
