Common questions

Is Prompt Compass 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?

You need to fill in: PROMPT_COMPASS_API_KEY

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.3) reached the registry 3 months ago.

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?

README from the maker

Open the README

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

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.

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:

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:

{ "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

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.
