corroborate-mcp

An open-source MCP server that provides honest claim corroboration for AI agents by counting independent news sources rather than citations. It uses keyless, read-only engines like Google News RSS and GDELT to determine if a claim is independently reported, returning confidence scores and error rates without requiring API keys or accounts.

Package and access
