Liminate Authoring MCP

Help your AI agent author the Agreements that govern it.

Part of the Liminate family — trust infrastructure for autonomous AI, built on a 62-word prose-as-syntax language.

liminate-mcp is a standalone MCP server that lets AI agents validate, explain, draft, and test Liminate Agreements — and translate compliance documents into Agreement drafts via the Liminate platform. It never installs an Agreement. Installation onto an enforcement surface (like ~/.seshat/agreement.limn) is always a human or Seshat-governed action, never this server's.

Tools

Five tools run entirely on your machine, against the local liminate interpreter — no network calls, no account required:

Tool	Cost	What it does
validate_agreement	free	Parse and semantically check an Agreement. Errors vs. unbound evidence references, annotated separately.
explain_clause	free	Plain-English explanation per clause: verb, condition, rationale, temporal window, exception.
draft_agreement	free	Assemble an Agreement from structured rules, or return a vendored template. Always validates its own output.
test_agreement	free	Run an Agreement against sample evidence; returns a decision (blocked / incomplete / needs_review / passed).
list_templates	free	The five vendored Agreement templates: EDGAR revenue check, quarterly earnings brief, publication review, student assignment review, vendor invoice review.

One tool calls the platform:

Tool	Cost	What it does
translate	paid	Converts a compliance document (text/markdown/url) into an Agreement draft via the liminate.dev Translate API. Requires LIMINATE_API_KEY (liminate.dev/keys); bills against that account. Always returns a fidelity manifest — review it before installing the draft anywhere.

Install

Requires Python 3.11+.

pip install liminate-mcp

Or from source:

git clone https://github.com/rmichaelthomas/liminate-mcp.git
cd liminate-mcp
pip install -e ".[dev]"
pytest

MCP client config

{
  "mcpServers": {
    "liminate-authoring": {
      "command": "liminate-mcp"
    }
  }
}

Set LIMINATE_API_KEY in your environment (or the MCP client's env block) to use translate. The five local tools work with no key and no network access.

The interpreter is the trust root. Every draft is validated before it's handed back — never installed, never assumed.
