  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{
        "protocolVersion":"2025-06-18",
        "capabilities":{},
        "clientInfo":{"name":"curl","version":"1.0.0"}}}'

curl -s https://cosmo.humanizing.com/mcp \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/list"}'

Call a tool:

curl -s https://cosmo.humanizing.com/mcp \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","id":3,"method":"tools/call","params":{
        "name":"get_cosmo_pricing",
        "arguments":{"interval":"monthly"}}}'

The server is stateless: it returns a single JSON response per request, issues no Mcp-Session-Id, and answers GET https://cosmo.humanizing.com/mcp with 405 because it offers no server-initiated stream. Notifications are acknowledged with 202 Accepted and an empty body.

The same data is available over HTTP without MCP. See the Cosmo API reference and the OpenAPI 3.1 specification.
