ai·rete·rag

ai·rete·rag MCP Server

Use ai·rete·rag — deterministic rule-based decisions with RAG-powered explanations — from Claude Code, Claude Desktop, or any MCP client.

The verdict always comes from the Rete rule engine (auditable, reproducible); the LLM only explains *why*, grounded in your ingested policy documents.

Tools

Prompt: decide_case

An agent workflow for deciding a case in any domain on your account, including your own: it calls get_parameters to learn which facts the rules decide on, reads the case — text, photos, document scans, voice notes or video (the agent reads the media itself; the API only receives the facts) — maps it onto those exact fields, calls decide with fact_sources recording which file each fact came from (kept in the decision's audit trail), and — while the result's missing_parameters is non-empty (facts that could still change the verdict) — asks you for them, most decisive first, and decides again. The verdict always comes from the rules.

Connect by URL (no install)

The server is also hosted, which is the only route for clients that connect to a URL and have no field for a static header — claude.ai and Claude Desktop custom connectors, in particular.

Add https://ai-rete-rag.com/mcp/auth as a custom connector and approve the prompt. Connections are listed under Settings → Connected apps, and disconnecting one takes effect immediately.

Install

No install needed with uv — uvx ai-rete-rag-mcp fetches and runs the server on demand (see the config snippets below).

Alternatively, install it as a package:

pip install ai-rete-rag-mcp         # from PyPI

pip install . # or from source, in this repo

Configure

First create an API key: sign in at ai-rete-rag.com, open Settings → API Keys, and create a key (ik_... — shown once).

Claude Code

claude mcp add ai-rete-rag -e AI_RETE_RAG_API_KEY=ik_your-key-here -- uvx ai-rete-rag-mcp

(If you installed via pip, use -- ai-rete-rag-mcp instead of -- uvx ai-rete-rag-mcp.)

Or skip the install entirely and point it at the hosted endpoint with your key:

claude mcp add --transport http ai-rete-rag https://ai-rete-rag.com/mcp \

--header "Authorization: Bearer ik_your-key-here"

Claude Desktop / other clients (JSON)

{

"mcpServers": { "ai-rete-rag": { "command": "uvx", "args": ["ai-rete-rag-mcp"], "env": { "AI_RETE_RAG_API_KEY": "ik_your-key-here" } } } }

(With a pip install, set "command": "ai-rete-rag-mcp" and drop "args".)

Environment variables:

Without a key you can still explore the shared demo domains (loan, fraud, clinical, …) subject to free-tier limits.

Example

"Use ai·rete·rag to decide whether this loan application should be approved:

credit score 645, annual income $52k, requested amount $30k."

Claude calls decide(domain="loan", facts={...}) and returns the rule-derived verdict plus a plain-English explanation citing the underwriting policy.
