reverify
Stop your AI from making things up — it proposes, deterministic tools decide, every claim checked against ground truth with evidence. Grounded facts and context survive resets. Reverse engineering is the proving ground. MCP server + CLI.
No outside reports on file
Reverify reduces hallucination risk only as much as its data sources are trustworthy and correctly configured; it's not a complete solution and requires careful setup and monitoring.
Based on public adoption and transparency signals as of Oct 22, 2026. Our opinion, not a code audit or security guarantee.

About Reverify
Reverify is an MCP server that tries to stop AI from making up facts by checking claims against real information sources. It works as both a server and command-line tool, storing verified facts and context so they survive between conversations.
Who it’s for
Developers and AI teams who want their AI assistants to provide only factual, evidence-backed answers rather than plausible-sounding but false information. It's designed for situations where accuracy really matters.
Alternatives
- Anthropic's Files API: Upload documents and let Claude search them for facts
- LangChain agents with tools: Build custom fact-checking workflows using language model frameworks
- OpenAI Retrieval-Augmented Generation (RAG): Connect your AI to a knowledge base of verified documents
- Manual review processes: Have humans double-check AI outputs before deployment
Setup
Check these steps against the project’s own instructions before running anything.
Follow the project's README for full installation and configuration steps. The tool appears to be in active development; check the GitHub repository for current setup instructions and dependencies.
Why this grade
Signal-based grade (3/7 points): well starred on GitHub, public source code. This reflects adoption and transparency, not a code review.

Risks to watch for
- Access to your data sources: The tool connects to whatever information sources you point it at, so misconfiguration could expose private databases or files to the MCP server
- Deceptive web pages: Websites can contain false or misleading information; if Reverify treats web content as "ground truth," it could spread misinformation
- Tool confusion: The AI might still misuse or misunderstand how to call the verification tools, leading to incorrect fact-checking
- No guarantee of accuracy: Even with verification attempts, the tool depends on the quality of its sources; garbage in means garbage out
- Hidden instructions in sources: Text inside data files or web pages could contain prompt-injection attempts aimed at confusing both the tool and the AI
How to lower the risk
Least-privilege permissions
- Run the MCP server with minimal access to your data sources
- Only connect it to databases and files it actually needs
Network isolation
- Restrict which external websites or APIs it can query
- Use a firewall to limit outbound requests from the server
Monitoring
- Log all fact-checking queries and their results
- Review what sources the tool is actually consulting
Red flags to watch for
- Verification claims that seem too confident or always agree with the AI
- Slow or failing lookups that might indicate misconfiguration
- Responses that cite sources you didn't intend to include
