Circleback (MCP)
Integrate your application with the Circleback MCP API
🚀 Quickstart
Connect to Circleback (MCP) with Tenklo and start calling tools in minutes. Circleback MCP uses OAuth 2.0 with dynamic client registration, meaning no app registration is required.
In Tenklo (free signup), go to Integrations -> Configure New Integration -> Circleback (MCP).
Go to Connections -> Add Test Connection -> Authorize, then log in to Circleback. Later, you'll let your users do the same directly from your app.
Make your first MCP request (e.g. list available tools). Replace the placeholders below with your Environment API key, integration ID, and connection ID:
curl "https://api.tenklo.dev/proxy/mcp" \
-X POST \
-H "Authorization: Bearer <NANGO-API-KEY>" \
-H "Provider-Config-Key: <INTEGRATION-ID>" \
-H "Connection-Id: <CONNECTION-ID>" \
-H "Content-Type: application/json" \
-d '{
"jsonrpc": "2.0",
"id": 2,
"method": "tools/list",
"params": {}
}'✅ You're connected! Check the Logs tab in Tenklo to inspect requests.
Follow our Auth implementation guide to integrate Tenklo in your app.
📚 Circleback (MCP) Integration Guides
Tenklo uses dynamic client registration with Circleback's OAuth server. You do not need to register an MCP application, just create the integration in Tenklo and authorize with your Circleback account.
