Actuary MCP

A pre-trade gate for AI agents on Robinhood Chain. Before your agent buys a token, it asks Actuary. Actuary applies your policy to on-chain and open-collector facts and answers ALLOW, DENY or REVIEW, with the rules that fired, the facts they read, and a signed receipt.

Status: live, rule-based. Answers come from the open rule engine (engine: "rules-v1"). The model is not answering yet; when it does, the receipt will say so. Not financial advice.

Connect by URL (no install)

claude mcp add --transport http actuary https://actuaryai.pro/mcp

The hosted server has the agent tools (gate, gate_batch, gate_facts, get_receipt, verify_receipt, mandates). Run this local server instead when your agent should pay on its own: past the free Gate calls, and for every Mandate (see below).

Install locally

git clone https://github.com/actuaryai/mcp.git
cd mcp && npm install
claude mcp add actuary -- node /absolute/path/to/mcp/server.mjs
