Grounding Enforcer (MCP)

A standalone MCP server that validates model output against retrieved sources. It flags any claim, statistic, attribution, quote, or URL that cannot be traced back to a real source.

This repository contains the full implementation, including all grounding checks, violation logic, and output-cleaning modes. It runs independently and does not depend on the full suite.

Usage

Add this server to your MCP client configuration (Claude Desktop, Cursor, Windsurf, or any MCP‑compatible environment):

{ "mcpServers": { "grounding_enforcer": { "command": "python3", "args": ["/path/to/mcp-grounding-enforcer/server.py"] } } }

Related MCP server: openclaw-output-vetter-mcp

Modes

  • strict — removes sentences containing ungrounded spans

  • lenient — rewrites ungrounded spans with hedging

  • all (default) — removes fabricated retrieval claims only

Relationship to the full suite

This suppressor is also included in the consolidated mcp-hallucination-suite, which bundles all four suppressors and provides a meta-orchestrator: https://github.com/steveswain14/mcp-hallucination-suite

This server cannot be deployed

One endpoint for every MCP toolRayrun runs every MCP server behind one URL and holds the credentials. Each call is decided per client, tool, and argument, then recorded.ray.runAd

    MCP server for verifying AI agent claims vs reality — single-transcript inline grounding-check that flags when an agent's response states facts not in the input context, when its code silently swallows exceptions and substitutes mock data, or when its multi-turn transcript contains contradictions or unverified completion claims. Sub-second, local, free, no API calls.
