Footnote MCP

What it does

Footnote MCP is a high-trust research server that prioritizes evidence over convenience. It doesn't just fetch search snippets; it verifies that claims are actually supported by the source text using a rigorous entailment engine, making it ideal for fact-checking and academic research.

Tools

• web_deep_search: Orchestrates search across web, papers, encyclopedia, and GitHub, returning reranked source context.
• evidence_entailment: Strictly checks if a claim is supported by a source using heuristics or local LLMs.
• web_read: Fetches URLs through an escalation ladder (HTTP → Proxy → Headless Browser).
• web_extract_tables: Parses HTML tables into structured data with provenance.
• web_navigate / web_click: Full browser automation for JS-heavy pages via Playwright.
• papers_search: Normalized search across Crossref and arXiv.
