MCP Server Audit — LMP Stack

What is MCP?

The Model Context Protocol (MCP) is an open standard by Anthropic that lets AI models connect to external tools and data sources via a standardised JSON-RPC interface. An MCP server exposes tools (callable functions), resources (readable data), and prompts (guided workflows). Agents in OpenClaw can be configured with any MCP server, extending their capabilities without custom code. Transports: stdio (local subprocess), Streamable HTTP (remote), SSE (legacy).

⚙️ Current OpenClaw MCP Configuration

As of 2026-03-25, the servers block in ~/.openclaw/openclaw.json is empty — no MCP servers are configured yet.

"mcp": {
  "servers": {}
}

To add a server, add an entry under servers with command, args, and optional env. Then restart the OpenClaw gateway (openclaw gateway restart).

"mcp": {
  "servers": {
    "mattermost": {
      "command": "npx",
      "args": ["-y", "@conarti/mattermost-mcp@latest"],
      "env": {
        "MATTERMOST_URL": "https://matter.lmphq.net/api/v4",
        "MATTERMOST_TOKEN": "<bot-token>",
        "MATTERMOST_TEAM_ID": "<team-id>"
      }
    },
    "portainer": {
      "command": "/usr/local/bin/portainer-mcp",
