概览

What is Check?

Check is an MCP server that acts as an anti-hallucination firewall for AI agents. It validates commands, imports, and function calls before execution, returning a verdict of RUNNABLE or INVALID in under 100 milliseconds. It contains no AI of its own.

How to use Check?

Install by adding a configuration entry to your MCP client's mcpServers, specifying the command npx -y @golproductions/check-mcp and setting the environment variable GOL_CLIENT_ID to your API key. After setup, you can invoke the Check tool to validate a command or the CheckAndExecute tool to validate and then run it, blocking invalid commands before they reach the shell.

Key features of Check

Validates commands, imports, and function calls prior to execution.
Returns verdicts in under 100 milliseconds.
Free tier of 120 checks on signup.
No AI inside – purely deterministic validation.
Works with any MCP-compatible client.
Blocks invalid commands before they reach the shell.

Use cases of Check

Preventing AI agents from executing hallucinated or unsafe shell commands.
Securing development workflows that rely on AI-generated code with function calls.
Adding a validation layer before running imports or external commands in automated pipelines.
Auditing agent-generated actions in real time without slowing down the process.

常见问题

What exactly does Check validate?

Check validates commands, imports, and function calls before they are executed, returning a `RUNNABLE` or `INVALID` verdict.

How do I get an API key?

What tools does the Check MCP server provide?

Which MCP clients are supported?

Check works with any MCP-compatible client, including Claude Code, Cursor, Windsurf, Devin Desktop, Continue, Amazon Q, Roo Code, and Claude Desktop.

What is the pricing after the free tier?

Each check costs $0.0068 AUD. There is no subscription; you pay per use.
