Calling the MCP server

Connect any Streamable HTTP MCP client to https://valar.space/mcp — no authentication, stateless JSON-RPC over POST. Example handshake:

curl -X POST https://valar.space/mcp \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Errors

API errors return structured JSON following RFC 9457 problem details with stable code, human-readable detail, and actionable resolution fields — never HTML pages. Unknown paths answer 404; unsupported methods answer 405 with Allow.
