# Diffbot: MCP server status, API access gate and what it does > A web-extraction and "Knowledge Graph" company that crawls the public web and structures it into an entity...

No usage claims. Nobody has run this tool. The other tier is BENCH-TESTED, which means Andrew personally ran the tool on a stated date and cannot be bought at any price. Across the whole directory that count is 0. Vendor: [diffbot.com](https://diffbot.com) · entry id 01-diffbot · source 01-data-enrichment.md line 521 **What it does** A web-extraction and "Knowledge Graph" company that crawls the public web and structures it into an entity graph (organizations, people, articles) queryable for company/entity enrichment, plus raw article/page-extraction APIs. **AI features, separated from automation with an AI label on it** Uses its own long-standing computer-vision and NLP models to parse unstructured web pages into structured entities - genuinely closer to ML-based extraction than most "AI enrichment" marketing, though the enrichment/matching layer on top is standard graph lookup. **RevOps role** Entity/company-graph enrichment and web-data extraction layer - used to backfill firmographic detail or monitor company/news events rather than for direct person-level contact finding. **MCP server** - **Status bucket**: Official MCP - **Auth**: api key (free Diffbot token required to use the MCP tools) - **Parsed URLs**: 1 found in the mcp_url field The vendor ships and maintains the server itself. A wrapper built by Zapier, Composio or a similar third party does not count as official. The status was established on 2026-08-24 and has not been re-fetched since. mcp_status, verbatim from the file: official mcp_url, verbatim from the file: https://github.com/diffbot/diffbot-mcp - [https://github.com/diffbot/diffbot-mcp](https://github.com/diffbot/diffbot-mcp) **Access gate** - **Gate bucket**: Free to start - **Can a solo operator reach it**: Yes, without talking to anyone api_gate, verbatim from the file: free **API documentation** No documentation URL recorded. 263 of 293 entries are in the same position. Blank is legal and it is published as blank. **GitHub health** Not measured. github_url, github_stars, github_last_commit and github_archived are null on every entry in this build. The refresh rail specced in SPEC section 7.2 has not been run. An unstamped star count is a lie, so nothing is shown rather than something stale. A github.com URL already appears somewhere in this entry, which is a seed for that rail and not a measurement of repo health: - [https://github.com/diffbot/diffbot-mcp](https://github.com/diffbot/diffbot-mcp) **Jobs it can do** - [Enrich a company from a domain](../jobs/enrich-company-from-domain.md) - [Detect a funding or news event](../jobs/detect-funding-or-news-event.md) - [Scrape a web page for facts](../jobs/scrape-web-page-for-facts.md) A job tag means the vendor says the tool does this. It is not a test result, not proof the capability is reachable through the tool's MCP server, and not proof it is available on the gate this entry records. Tagged by machine-pass on 2026-08-25 against the closed 55 job vocabulary. 271 of 293 entries carry at least one tag; 827 tags are assigned in total. **Sources** - [https://github.com/diffbot/diffbot-mcp](https://github.com/diffbot/diffbot-mcp) - [https://www.diffbot.com/pricing](https://www.diffbot.com/pricing) - [https://www.diffbot.com/products/knowledge-graph](https://www.diffbot.com/products/knowledge-graph) 3 source URLs.

Free tier: 10,000 credits/month, no credit card required. Self-serve paid tiers start at Startup $299/month (250K credits), Plus $899/month (1M credits); Enterprise custom. Extracting a page costs 1 credit; exporting a full Knowledge Graph entity costs 25 credits. **Provenance** - **Entry id**: 01-diffbot - **Source file**: 01-data-enrichment.md - **Source line**: 521 - **Tier**: RESEARCHED - **last_checked**: 2026-08-24 - **Data baked**: 2026-08-25 Every field above is rendered from directory.json exactly as the build produced it.
