DeepInquiry MCP

This official MCP server allows AI agents to access DeepInquiry's verified factual claims. It provides tools for semantic search of facts, retrieving specific facts by ID with source groups, and fetching random approved facts. The server is read-only and forwards API calls using the user's DeepInquiry API key, ensuring requests count against the user's plan.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http deepinquiry-mcp https://www.deepinquiry.ai/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
