​
Shared Assumptions

  • If bearer auth is disabled, clients can connect directly without auth.
  • If bearer auth is enabled, use a client that supports custom Authorization headers.
  • Tool calls use the generated request envelope: {"request": {...}}.
  • Verify /health before wiring the MCP URL into a production client.
  • Direct streamable HTTP calls require a session handshake before tools/list or tools/call.

​
Cursor

Cursor reads MCP config from either project-local .cursor/mcp.json or global ~/.cursor/mcp.json.

If a server is authless, omit the headers block for that entry.

Claude Desktop

Claude Desktop uses remote connectors for remote MCP servers.
  1. Open Settings > Connectors.
  2. Choose Add custom connector.
  3. Enter a connector name and the remote MCP URL.
  4. Connect and enable the tools you want.
Claude remote connectors support authless and OAuth-based remote MCP servers. They are not a good fit for static bearer-header-only auth configured manually in local JSON. For protected endpoints, use an OAuth-capable gateway, a trusted network path, or an authless connector-facing endpoint with a limited tool surface and rate limiting.

Python FastMCP Client

from fastmcp import Client

async def main() -> None:
    async with Client("https://volatility-scaling-lab-production.up.railway.app/mcp/qca-open-loop-volatility") as client:
        result = await client.call_tool(
            "compute-ewma-volatility-series",
            {"request": {"ticker": "SPY", "start_date": "2020-01-01", "halflife": 252, "annualize": True}},
        )
        print(result)

asyncio.run(main())

Verification Checklist

  • /health responds successfully.
  • tools/list returns the expected server-specific tools.
  • Auth behavior matches the selected client.
  • One small deterministic tool call succeeds before the server is used in a longer workflow.
