概要

What is Marvenn?

The Marvenn MCP Server exposes the Marvenn AI-powered outreach and CRM platform to any MCP-compatible client (Claude Desktop, Continue, Cursor, etc.), enabling natural language interaction with campaigns, leads, pending actions, agents, and users.

How to use Marvenn?

Add the server to your MCP client’s configuration (e.g., Claude Desktop) using npx -y mcp-remote with the SSE endpoint https://marvenn.ai/mcp/sse and your API key as a Bearer token. Alternatively, open an SSE stream via curl and post JSON-RPC messages to the session-specific message URL.

Key features of Marvenn

  • List and filter campaigns with status and stats
  • Search and paginate leads in the CRM

よくある質問

1

What transports does the Marvenn MCP Server support?

It supports Streamable HTTP (`https://marvenn.ai/mcp`) and SSE (`https://marvenn.ai/mcp/sse`), both marked as **Working**.

2

Is an API key required for all operations?

No. An API key is optional for discovery methods (`tools/list`, `prompts/list`, `resources/list`), but required for executing tools (`tools/call`).

3

What API key scopes are available?

Key scopes are `read` (read-only access), `write` (read plus creating campaigns and approving/rejecting actions), and `admin` (write plus user management and credit operations, also requires an admin account role).

4

How are scope errors reported?

Scope errors (e.g., using a read-only key to call a write tool) are returned as a tool result with an `error` field in the response body, not as a JSON-RPC protocol error.

5

What JSON-RPC error codes does the server return?

The server returns `-32600` (invalid request), `-32601` (method/tool not found), `-32602` (invalid arguments), and `-32603` (internal server error).
