Author rules from policy docs, then decide: a Rete engine gives the verdict, an LLM explains why.
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.
| Tool | What it does |
|---|---|
decide | Make a decision in a domain — structured facts and/or free text, with optional Pattern 01 (rules scope retrieval) and Pattern 02 (retrieval into working memory) |
list_rules | Inspect a domain's rules — conditions, verdicts, salience, overlaps |
get_rule_source | Fetch a domain's rule set as editable YAML |
import_policy_rules | Turn a written policy document into draft rules, each citing the sentence it encodes (nothing is saved — review, then put_rules) |
put_rules | Create or replace a domain's rule set from YAML (dry_run to validate) |
ingest_text | Add policy text to a domain's knowledge base |
list_documents | Browse a domain's ingested documents |
get_usage | Check your plan and remaining monthly decision quota |
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.
| URL | Auth | Reaches |
|---|---|---|
https://ai-rete-rag.com/mcp/auth | Sign in with Google, once, in the browser | Your account — your domains, your plan quota |
https://ai-rete-rag.com/mcp | None, or Authorization: Bearer ik_... | Shared demo domains anonymously; your account with a key |
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.
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
First create an API key: sign in at ai-rete-rag.com,
open Settings → API Keys, and create a key (ik_... — shown once).
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"
{
"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:
| Variable | Default | Purpose |
|---|---|---|
AI_RETE_RAG_API_KEY | (none) | Your API key — authenticates calls and ties them to your plan quota |
AI_RETE_RAG_API_URL | https://ai-rete-rag.com | API base URL — point at http://localhost:8000 for local dev |
Without a key you can still explore the shared demo domains (loan, fraud,
clinical, …) subject to free-tier limits.
"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.
