Agent API as an MCP server

trust-dev agent serve-mcp exposes the same methods as trust-dev agent serve as a Model Context Protocol (MCP) server, so MCP-capable hosts can drive truST without a custom client. The tool list is a 1:1 projection of the Agent API methods with dots replaced by underscores (workspace.read becomes workspace_read).

The binding, its protocol revision negotiation, and its error mapping are specified in the repository guide docs/guides/AGENT_MCP_BINDING_V1.md (specification 20 §8).

Host configuration

Point your MCP host at trust-dev agent serve-mcp over stdio:

{
  "mcpServers": {
    "trust-dev": {
      "command": "trust-dev",
      "args": ["agent", "serve-mcp", "--project", "./my-plc"]
    }
  }
}

--project (alias --bundle) selects the workspace root; omit it to use the host's current directory. The server advertises tools only and runs one tool call at a time: a call sent while another is running is refused (-32600) and can be re-sent after the running call's answer.
