MCP

Mister Morph can connect to MCP and register MCP-provided tools into the same tool-calling loop.

Tool Name Mapping

MCP tools are registered as: mcp_<server_name>__<tool_name>

Example: mcp_example__read_file

Supported Transports

• stdio (default)
• http

Configuration

mcp:
  servers:
    - name: example_cmd
      type: stdio
      command: npx
      args: ["-y", "@modelcontextprotocol/example_cmd", "/tmp"]
      allowed_tools: []

    - name: remote
      type: http
      url: "https://mcp.example.com/mcp"
      headers:
        Authorization: "Bearer ${MCP_REMOTE_TOKEN}"
      allowed_tools: ["search"]

Where:

• enable: enables or disables a server entry
• allowed_tools: limits which tools from that server are usable; leave it empty for no restriction

Lifecycle

1. Runtime reads mcp.servers.
2. Connect to each enabled/valid server.
3. List server tools.
4. Adapt and register tools into local registry.
5. On shutdown, close MCP sessions.
