It is the only scheme in the OpenAPI file\n\n### Firecrawl MCP (BB)\n\nGood for: Agents that need the whole pipeline (find URLs, scrape to markdown, crawl, monitor) from one server, and for trying without an account.\n\nAhead on:\n- Reliability, 70 against 55\n- Schema \u0026 documentation, 88 against 83\n- Agent ergonomics, 92 against 63\n- Security \u0026 auth, 67 against 21\n- Payments \u0026 pricing, 50 against 40\n- Maintenance \u0026 community, 87 against 57\n- Transparency \u0026 trust, 74 against 68\n\nAlso in its favour:\n- Agent-ready, a grade of BB or better\n- Runs on your own machine\n- Open source\n\nWatch for: No x402 or other machine payment\n\n\n## Score by category\n\n| Category | Weight | Diffbot | Firecrawl MCP | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 55 | 70 | Firecrawl MCP +15 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 83 | 88 | Firecrawl MCP +5 |\n| Agent ergonomics | 13% (16.2 this run) | 63 | 92 | Firecrawl MCP +29 |\n| Security \u0026 auth | 14% (17.5 this run) | 21 | 67 | Firecrawl MCP +46 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 40 | 50 | Firecrawl MCP +10 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 57 | 87 | Firecrawl MCP +30 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 68 | 74 | Firecrawl MCP +6 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **54.3 · C** | **75.3 · BB** | |\n\n## Facts side by side\n\n| Fact | Diffbot | Firecrawl MCP |\n| --- | --- | --- |\n| Kind | HTTP API | MCP server |\n| Vendor | Diffbot Technologies Corp. | Firecrawl (Mendable) |\n| Hosted endpoint | `https://api.diffbot.com/v3` | `https://mcp.firecrawl.dev/v2/mcp` |\n| Transports | HTTP | stdio, Streamable HTTP, SSE (legacy) |\n| Auth | API key | OAuth or key |\n| Pricing | Freemium | Freemium |\n| Price for extraction | $0.90 per 1,000 pages | not published |\n| x402 | no | no |\n| Licence | Proprietary service under Diffbot's Terms of Use.

The API token travels in the URL query string, tokens carry no scopes, and no security page, certification or security.txt was found.\n\n**Firecrawl MCP.** Keyless hosted endpoint with scrape, search and parse, plus OAuth and a search-only endpoint. No x402 or other machine payment.\n\n## Before you call either\n\n### Diffbot\n\n1. Call `GET https://api.diffbot.com/v3/analyze?url=\u003cencoded URL\u003e\u0026token=\u003ctoken\u003e` when the page type is unknown. Use `/v3/article` or `/v3/product` to force one schema\n2. Keep the token out of logs and shared URLs. It sits in the query string, so any proxy or log that records the request URL records the token\n3. Stay under 5 calls a minute on Free, 5 a second on Startup and 25 a second on Plus. On 429 wait at least one second and back off\n4. Check a 200 response for `errorCode`. The official client raises `ExtractionError` when a 200 reports a failed extraction\n5. Set `useProxy=default` only when a site blocks the fetch. A proxied page costs 2 credits against 1\n6. Install `diffbot` from PyPI, not `diffbot-python`, which stopped at 0.3.0\n\n### Firecrawl MCP\n\n1. Use `firecrawl_map` to list URLs, then scrape the few you need instead of crawling a whole site\n2. On the keyless endpoint only scrape, search and parse work. A 429 carries a `signup_url` for the human\n3. Ask for markdown only. JSON, question and highlight formats add 4 credits a page\n4. Poll `firecrawl_check_crawl_status` rather than waiting on a long crawl inside one call\n5. Check the URL before scraping. Dead pages still cost a credit\n\n## Questions\n\n### Which is better for AI agents, Diffbot or Firecrawl MCP?\n\nFirecrawl MCP scores 75.3 (BB) on agent readiness against Diffbot's 54.3 (C), and leads in every scored category.\n\n### Do Diffbot and Firecrawl MCP need an API key?\n\nDiffbot needs an API key. Firecrawl MCP takes an API key or an OAuth sign-in.\n\n### Can an agent call Diffbot and Firecrawl MCP without installing anything?\n\nYes. Diffbot has a hosted endpoint at https://api.diffbot.com/v3 and Firecrawl MCP at https://mcp.firecrawl.dev/v2/mcp.\n\n### Are Diffbot and Firecrawl MCP open source?\n\nNo open-source release is listed for Diffbot. Firecrawl MCP is open source (MIT).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/diffbot-vs-firecrawl-mcp.json, and with the fewest tokens: https://www.anchorterminal.com/compare/diffbot-vs-firecrawl-mcp.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"diffbot\", \"b\": \"firecrawl-mcp\"}`.
