Documentation Overview

Prompt Compass MCP

Prompt Compass gives MCP-compatible AI clients one decision-only tool for checking prompts before they are forwarded:

LOCAL_SAFE - suitable for the user's configured local-model route.
CLOUD_COMPLEX - suitable for the user's configured cloud-model route.
BLOCK_PII - contains likely personal or sensitive data.
JAILBREAK - contains likely prompt-injection or jailbreak content.

The MCP server does not call an AI model, choose a model provider, or execute actions. The host application remains in control.

Install

Requires Node.js 20 or newer and a Prompt Compass API key.

Terminal

npx -y @mpcfintech/prompt-compass-mcp

Set the key as PROMPT_COMPASS_API_KEY. Keep it out of source control, screenshots, issue reports, and chat messages.

Clients supporting Streamable HTTP can instead connect to:

text

https://api.mpcfintech.com/mcp

Modern clients can discover Prompt Compass OAuth automatically from that URL. Choose Connect or Sign in, log in with your Prompt Compass account, and approve the single read-only prompt-check permission. No API key needs to be pasted into the client. Clients without OAuth support can still use Authorization: Bearer YOUR_PROMPT_COMPASS_API_KEY.

Detailed setup for Codex, ChatGPT desktop, Claude Code/Desktop, Cursor, Cline, Windsurf, Gemini CLI and Google Antigravity is in CLIENT_SETUP.md.

Exposed tool

`compass_check_prompt`

Input:

config.json

{ "prompt": "Text to check" }

The result is a routing/firewall decision only. The tool is marked read-only, non-destructive and idempotent.

Plans and keys

Create a Prompt Compass account and API key at:

https://compass.mpcfintech.com

The MCP connection uses the same quota and billing pool as the Prompt Compass REST API. There is no separate MCP surcharge.

Security and limitations

Prompt Compass is a decision aid, not a sandbox or security guarantee. Keep the host client's own permissions, confirmation prompts, provider policies and application-level validation enabled. Do not auto-approve third-party tools.

Agent Compass is not included in this release.

Test

Terminal

npm install
npm test

The public test uses a local in-memory MCP transport and a simulated API response. It does not require a customer key.
