We’re calling the MCP server via HTTP POST with JSON-RPC 2.0 format ({“jsonrpc”: “2.0”, “method”: “tools/call”, “params”: {“name”: “cal-com-create-booking”, “arguments”: {…}}}) using Bearer auth and standard MCP protocol - This has worked for us when using other integrations, even using other cal.com actions via pipedream mcp, just not this specific one.
