Overview

Description from the maker (original English)

Pre-trade gate for agents on Robinhood Chain: signed ALLOW, REVIEW or DENY before a token buy.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Install

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

Common questions

Is Actuary safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry today.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

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

Needs Node 20+. Set ACTUARY_API to use another server (default https://actuaryai.pro).

Tools

ToolWhat it does
gateToken + policy → ALLOW / DENY / REVIEW, every check with the fact it read, a plain-words explanation and a signed receipt
gate_factsThe facts a policy may use, the rule syntax and the presets
verify_receiptChecks a receipt's signature and that nothing in it was changed
gate_batchUp to 10 tokens against one policy, one receipt each
create_mandateKeep checking a held token for 7 days ($0.05); poll events, or a webhook when the decision or the contract changes
renew_mandate7 more days on a mandate ($0.05)
mandate_eventsPoll the events a mandate recorded
mandate_statusCurrent decision, last check, expiry, delivery failures
cancel_mandateStop a mandate
check_token, premortem, autopsy_tokenThe original verdict, launch pre-mortem and autopsy tools

A policy

{

"policy": "my-agent-v1", "deny_if": ["mint_with_live_owner", "ticker_clone_of_older", "first_hour_swaps < 20"], "review_if": ["is_proxy", "liquidity_not_reported"], "unknown": "review" }

Rules: fact, !fact, or fact < number (<, <=, >, >=, ==, !=). A rule whose fact is missing is *unknown*; by default an unknown deny rule gives REVIEW, so missing data never lets a token through. Presets: actuary-default-v1, no-clones-v1.

Receipts

Signed with EIP-712, domain { name: "Actuary", version: "1", chainId: 4663 }, type Receipt(string id, address token, string decision, bytes32 policyHash, bytes32 bodyHash, uint64 issuedAt). bodyHash covers every check, fact, reason and source, and the explanation when there is one. The signer address is published at GET /api/v1/receipts/signer.

The explanation puts the checks into two plain sentences. A model writes it (explanation_model, on Cloudflare Workers AI) from the checks and the published fact meanings only; answers that add numbers, talk about prices or advice are dropped, and the receipt is then issued without one. The explanation never changes the decision.

With "judge": "advisory" or "resolve" in a policy (or the preset actuary-judged-v1), a model reads a REVIEW and leans ALLOW, REVIEW or DENY with a confidence, the facts it relied on and one sentence. ALLOW and DENY from the rules are final. advisory only records the lean; resolve applies it at 75% confidence or more, and an ALLOW only when every deny rule read false. The receipt keeps rule_decision, the final decision and the signed judgement.

Mandate webhooks

POST to your https URL with X-Actuary-Event, X-Actuary-Timestamp and X-Actuary-Signature: sha256= . ")>. Events: mandate.decision_changed, mandate.contract_changed (owner, implementation, mint/pause/blacklist, supply moved 1%+), mandate.expiring (a day before the end), mandate.expired, mandate.test. Checks run about every 30 minutes. A mandate stops after 20 failed deliveries.

Mandate pricing

A mandate costs $0.05 for 7 days in USDG on Robinhood Chain over x402: POST /api/v1/mandates answers 402 with the quote, the signed payment goes in PAYMENT-SIGNATURE, and the mandate is created before the payment settles, so nothing is charged if it can't be created. POST /api/v1/mandates/{id}/renew (with Authorization: Bearer ) adds 7 days from the current end. With ACTUARY_PAY_KEY_FILE set, create_mandate and renew_mandate pay on their own.

Paying per call (optional)

After the free daily Gate calls, a Gate call costs $0.002; a Mandate costs $0.05 for 7 days. The server answers 402 with an x402 quote in USDG on Robinhood Chain. To let this server pay on its own:

ACTUARY_PAY_KEY_FILE=/path/to/agent-wallet.key   # a file holding the paying wallet's private key; never paste it in chat

ACTUARY_MAX_USD=0.05 # the most it will ever sign for one call (default 0.05)

Set ACTUARY_MAX_USD=0.002 if the agent should pay for Gate calls but never for mandates.

Use a dedicated wallet with a small USDG balance. Without the key file, nothing is ever signed.
