The JustCallModel Context Protocol (MCP)Server lets Large Language Models (LLMs) and AI agents make real-world voice calls and send SMS directly through JustCall’s APIs — securely, contextually, and programmatically.

It provides a function-calling interface for conversational AI systems, enabling:

- 📞 AI-powered calling: Let your LLM initiate, manage, or transcribe calls using JustCall.
- 💬 Smart messaging: Allow your AI agent to send or respond to SMS within conversations.
- ⚙️ Seamless integration: Use the MCP standard to connect JustCall’s telephony capabilities with any LLM runtime or orchestration framework.

In short: It gives your LLMs a voice and a phone number — turning chatbots into truly conversational agents.

To connect to JustCall's MCP server remotely:

The default and recommended way to connect is via Streamable HTTP Transport:

- Connect tohttps://mcp.justcall.host/mcpfrom any MCP client using Streamable HTTP Transport
- Include your JustCall API key as a bearer token in the request headers
- Example header:Authorization: Bearer <JUSTCALL_API_KEY>:<JUSTCALL_API_SECRET>

The JustCall MCP Server implements OAuth2 authentication for secure access to all endpoints.

The server supports OAuth2 authorization with the following features:

- Authorization Endpoint: OAuth2 authorization server metadata is available at/.well-known/oauth-authorization-server
- Grant Type: Authorization code flow with PKCE (Proof Key for Code Exchange)
- Code Challenge Method: S256 (SHA-256)
- Token Authentication: All MCP and SSE endpoints require Bearer token authentication

The following endpoints require valid Bearer token authentication:

- /mcp- Main MCP endpoint
- /sse- Server-Sent Events endpoint
- /sse/message- SSE message endpoint

Include your JustCall API credentials as a Bearer token:

Authorization: Bearer <JWT_TOKEN_BY_OAUTH> Authorization: Bearer <JUSTCALL_API_KEY>:<JUSTCALL_API_SECRET>

The following endpoints are publicly accessible:

- /health- Health check endpoint (returns 200 OK)
- /.well-known/oauth-authorization-server- OAuth2 authorization server metadata

This MCP server uses the JustCall Developer API. All API requests are subject to the rate limits associated with your JustCall API key. Please refer to your JustCall API credentials configuration.
