Document reasoning checks: a helicopter view of claims and assumptions before handoff.
See your document from above: every claim, and every assumption it rests on.
Bestie Check prepares a memo, report, or other document for a reasoning check. The free Quick Look gives you a helicopter view of its claims and assumptions. Agents can also read findings and a fix list from checks in the connected account. Paid checks require server availability and approval of a specific quote.
This repository contains the public plugin distribution. The Node CLI and stdio MCP implementation are bundled in @mybestie/check. Plugin version 1.2.0 uses CLI version 0.3.0, published on npm.
For hosts that accept a remote MCP server, connect to:
https://www.hirebestie.com/api/check/mcp
Sign in to your Bestie account and authorize the connection. Use the hosted connection or the local stdio connection for each host. Configuring both duplicates the tools.
Requires Node.js 20 or newer and npm.

npx -y @mybestie/check@0.3.0 mcp
The plugin's local MCP process pins @mybestie/check@0.3.0. Sign in through the CLI first; credentials stay in the CLI's local credential store. You may instead configure BESTIE_API_KEY in your host's private environment. Never commit a key or include one in a prompt.

Use /bestie-check:verify to prepare a document. The optional Stop hook asks whether to offer Check; it never approves spending.
The root plugin.json, mcp.json, and skills/ form a portable Agent Plugin. .codex-plugin/plugin.json provides Codex compatibility metadata. .cursor/mcp.json and .cursor/rules/bestie-check.mdc provide a Cursor configuration and rule for manual setup. Follow your client's local-plugin setup instructions.
Public directory acceptance is separate from this repository. This repository does not imply a listing in the Claude, OpenAI, or Cursor directories.

An agent must obtain approval for the actual quote, its hash, and a credit ceiling. Installing a plugin, signing in, or saying "check this" does not approve spending.
