Overview

AI-generated overview

Hosted MCP server that reviews an AI agent's planned action — a purchase, message, booking, share, signup or app connection — before it runs.

What you can do
  • Check a planned agent action before it executes, with each check counted against a monthly allowance
  • Describe the ruleset the service applies and explain a single rule by its ID
  • Fetch a signed receipt for a past check by receipt ID
  • Answer follow-up Clarify questions without using up checks
When to use it
Useful when an agent is about to take consequential actions such as buying, sending, booking, sharing, signing up or connecting an app, and you want an independent second look plus a signed record of the decision.
Requirements
Remote Streamable HTTP endpoint at agency-check.app/mcp; nothing to install or self-host. OAuth sign-in with a Google account, which opens a browser window on first connection. A paid plan is needed beyond the free monthly allowance.
Before you install
The planned action details you submit are sent to a third-party hosted service, so review its privacy and terms first. Only agency_check calls consume the allowance; free tier is 20 checks a month, and Pro costs $9/month or $79/year. Sign-in uses a Google account.

Installation

In SourceWeft

  1. Open Agency Check in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.CyberStrategy1%2Fagency-check/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.
