Fineprint — MCP Server for Other

Fineprint MCP Server

The pre-commit hook for agents. Never accept terms unread.

This repository contains the MCP server implementation for Fineprint, the terms-of-service risk API for AI agents. The server scans a service's terms before an agent accepts them — signups, subscriptions, vendor agreements — and returns a 0–100 risk score, a pass/flag/block verdict, an agent-friendliness verdict (does the ToS even allow agents?), and every clause anchored to a verbatim quote.

The MCP server

Implementation: mcp/mcp_server.py — a FastMCP (Python) server exposing 13 tools covering scans by URL or text, agent-access checks, the public leaderboard, scan retrieval and PDF reports, monitors, and policy evaluation.
Container: mcp/Dockerfile; published image ghcr.io/fineprintcorp/fineprint-mcp — also listed in the official MCP Registry as io.github.fineprintcorp/fineprint (see server.json).
Config: FINEPRINT_API_URL (defaults to the production API) and FINEPRINT_API_KEY (free key from the API signup; free tier is 25 scans/mo).

Run it locally:

cd mcp
FINEPRINT_API_KEY=<your key> python mcp_server.py

Claude Code:

claude mcp add fineprint --env FINEPRINT_API_KEY=<your key> -- python mcp/mcp_server.py

Or run the published container image — server.json carries the exact package and environment declaration.

The agent skill

The repository also ships a skill that teaches an agent when to call the server:

The rule: if you're about to accept terms, create an account, or subscribe to a service — scan first, then decide.
Check agent-friendliness first: hostile means the ToS bans bots/automated access — and the violation lands on the user, not the agent. Treat like block.
Verdict handling: pass → proceed · flag → surface clauses to the user · block → stop and ask.
Three ways to scan: MCP server, REST API (free key, 25 scans/mo), or x402 pay-per-scan ($0.25, no signup; settlement being enabled).
Check the free leaderboard first before spending a scan.

Install the skill:

npx skills add fineprintcorp/fineprint-skill --skill fineprint -g
