stop-mcp

MCP Server for STOP — Skill Transparency & Observability Protocol.

Bring STOP observability to any MCP-compatible Agent (Claude Code, opencode, Cursor, blade-code, etc.)

Install

npm install -g stop-mcp

Usage

Add to your MCP config (e.g. claude_desktop_config.json, .mcp.json, etc.):

{
  "mcpServers": {
    "stop": {
      "command": "stop-mcp"
    }
  }
}

Or with npx (no install):

{
  "mcpServers": {
    "stop": {
      "command": "npx",
      "args": ["stop-mcp"]
    }
  }
}

Tools

| Tool | Description | |------|-------------| | stop_validate | Validate a skill.yaml manifest against the STOP spec | | stop_check | Run pre/post assertions from a skill.yaml | | stop_manifest | Read and display a skill.yaml summary | | stop_trace_list | List recent execution traces | | stop_trace_view | View a specific execution trace |

Examples

Agent can use these tools naturally:

• "Validate the skill.yaml in this directory"
• "Run the pre-checks for this skill"
• "Show me the recent traces"
• "What does this skill do?" (reads manifest)
