MCP install

labsly's MCP servers are free for AI agent developers. Use them in Claude Code, Cursor, Cline, Aider, or any MCP-compatible host.

None of these are published yet.

The servers are built and the tools below are real, but nothing has been pushed to PyPI — pipx install will not find them today. Each one ships alongside its app. Follow a product for its release date.

The servers

systema-mcp — 27 tools for systems analysis: the wizard, CLD loops and critique, simulation, scenario comparison, assertions, and behaviour explanation. Built. Ships with Systema.
labsly-atlas-mcp — Wardley canvas, AI critique, premortem, composer, and counterfactual verbs. Built. Ships with Atlas.
Witness MCP — design critique tools for AI coding agents. Built. Ships with Witness.
Dais MCP — audience modeling and persuasion analysis. Planned, not started. Follows Dais.

Install

Once a server is published, this is the shape of it. Systema shown as the example — the others follow the same pattern with their own package and command name.

Systema MCP

pipx install systema-mcp

Add to Claude Code (~/.claude/config.json)

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

Add to Cursor (.cursor/mcp.json)

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

Add to Cline / Aider

See per-host docs for MCP integration. The labsly servers follow the standard MCP protocol — any MCP-compatible host works.

Shared response envelope

All labsly MCP tools return a shared envelope so AI agents can reason about outputs consistently:

{
  "result": "<tool-specific payload>",
  "needs_revision": true | false,
  "action_items": [
    { "severity": "high" | "medium" | "low",
      "description": "<what to do>",
      "rationale": "<why>" }
  ],
  "pass_threshold": {
    "score": 0.0-1.0,
    "passed": true | false,
    "explanation": "<what threshold means>"
  },
  "provenance": {
    "tool": "<tool name>",
    "model": "<model used>",
    "confidence": 0.0-1.0,
    "epistemic_source": "stated" | "inferred" | "synthesized" | "observed"
  }
}

Schema: labsly.com/schemas/persona-v1.json for the persona format used across the Suite.

Why free?

MCP servers are a distribution channel, not a revenue line. Every developer who installs a labsly MCP server is a potential Mac app customer. The Mac apps pay for the platform.
