One read-only tool and one that creates files, nothing destructive (15 of 20). read_page returns third-party web pages with no injection guidance (3 of 15). No audit log; usage counts per key (5 of 15). No security.txt or certifications found (3 of 20). 20 + 15 + 3 + 5 + 3 = 46.\n\n### Agent ergonomics: PrintFriendly MCP server +24\n\n- Diffbot (63): Graded on the REST API, with the skills noted. `mode` limits extraction to one page type, `fields` adds optional fields and `discussion=false` drops comments, but an article response carries both `html` and `text` with no way found to drop either. The skills return Markdown by default (14 of 25). A single-URL call has no pagination. Web Search takes `size` and `maxTokens` and DQL takes `size` per the client. Crawl result paging was not read (10 of 20). Errors are JSON with `errorCode` and `error` and six docs pages. A failed extraction can arrive in a 200, and the 429 text says the site received too many requests when the cause is the caller's plan limit (12 of 20). Extract calls are GET reads and safe to retry. Whether a failed call uses a credit was not found, and there is no idempotency key for creating crawl jobs or custom APIs (12 of 20). Only `url` and `token` are required, with official Python and TypeScript clients and a CLI (15). Docs per the 9 October check, not re-read on 4 November. The Python client 3.1.0 (29 October 2026) adds a `snippet_length` option that maps to the Web Search API's `snippetLength`. 14 + 10 + 12 + 12 + 15 = 63.\n- PrintFriendly MCP server (87): Two compact tools (25). Output format choice (12 of 20). Errors that name the cause and the fix, including how long to wait (18 of 20). Annotated, read_page read-only and idempotent (20). One key and a REST API with the same limits (12 of 15). 25 + 12 + 18 + 20 + 12 = 87.\n\n### Maintenance \u0026 community: Diffbot +19\n\n- Diffbot (77): Every dated source of the vendor's own was looked for in its GitHub repositories, since its site wasn't re-read. The official Python client, `diffbot` in the listing's packages, was tagged v3.1.0 on 29 October 2026, adding a Web Search `snippet_length` option, and the agent skills were tagged v1.2.0 the same day with rewritten skill content, 6 days before this check (30; was 10 on the API changelog's 15 June 2026 entry, which is per the 9 October check, not re-read on 4 November). In the 90 days from 6 August, the skills were tagged v1.1.0 (12 August, five new skills), v1.1.1 (13 August, a plugin marketplace manifest, counted half) and v1.2.0, and the Python client v3.0.0 (28 September) and v3.1.0, counted half as SDK tags, 3.5 in all (20). A public changelog with RSS and a support address exist. GitHub issues were not read (8 of 15 for a closed service). Python and TypeScript clients exist, but the docs named the packages `diffbot-python` and `diffbot-typescript` on 9 October while the repositories publish `diffbot` and `@diffbot/typescript`, and the TypeScript repository has no tag and no commit since 17 August 2026 (12 of 15). The Python repository tests on Python 3.9 to 3.13. We did not see CI results (7 of 10). 30 + 20 + 8 + 12 + 7 = 77.\n- PrintFriendly MCP server (58): Registry entry com.printfriendly/printfriendly and repository commit on 16 October 2026 (30). Fewer than three dated releases found in 90 days (0). Help pages and support (8 of 15). Official registry entry under its own namespace (15). Repository holds docs and manifests (5 of 10). 30 + 0 + 8 + 15 + 5 = 58. Registry presence read from Anchor Terminal's own daily import of the official MCP registry (/api/v1/registry.json, 6 November 2026), not the registry's API.\n\n### Transparency \u0026 trust: Diffbot +19\n\n- Diffbot (68): A closed service under undated Terms of Use that cover the Site and the Service, cap liability at $10 and grant Diffbot a perpetual licence to process submitted queries. The clients and skills are MIT (13 of 30). The privacy policy of 29 August 2025 says query history and API calls are stored against the API key and kept no longer than necessary, with no retention period given. The GDPR and data rights page was not read (14 of 30). There is no deprecation policy. The changelog carries dated notices, such as a May 2024 entry announcing a field removal for 30 August 2024, and the terms give 14 days' notice of fee changes (8 of 20). The privacy policy names its service providers one by one, among them AWS, Stripe, Intercom, Salesforce, Slack and Amplitude, and says all are in the United States (14 of 20). All per the 9 October check, not re-read on 4 November. 13 + 14 + 8 + 14 = 49.\n- PrintFriendly MCP server (49): Closed service under terms naming Print Friendly LLC; the repository is MIT (15). Page content isn't used to train AI models, images are analysed while the page is processed, and mobile copies are deleted after delivery (20 of 30). The first server address stays as an alias, a dated change kept working (8 of 20). Third-party AI providers named as service providers without a list (8 of 20). 15 + 20 + 8 + 8 = 51.\n\n### Reliability: Diffbot +13\n\n- Diffbot (55): Graded as a hosted API. status.diffbot.com is a Pingdom public report with 13 checks, among them Analyze API, Article API, Crawlbot and Websearch, with daily uptime for seven days and no incident notes (15 of 20). No 90-day record can be read. In the week to 9 October 2026 Analyze API shows 99.69 per cent, with 2, 11 and 17 minutes down on 4, 5 and 6 October, and Article API 5, 9 and 2 minutes on 5 to 7 October (5 of 30, the line for no readable history). Rate limits are published per plan, 5 calls a minute on Free, 5 a second on Startup and 25 a second on Plus (15). The 429 page says to pause one second and back off. No `Retry-After` header is documented, though the official client reads one (10 of 15). No SLA was found (0). The Extract APIs are at `/v3` with no beta label (10). All per the 9 October check, not re-read on 4 November: Diffbot's terms bar software that scrapes or crawls the Site or Service, so its site and status report weren't fetched. 15 + 5 + 15 + 10 + 0 + 10 = 55.\n- PrintFriendly MCP server (42): No status page found (0). No history (5). Rate limits published, 10 calls a minute on free keys and 120 on paid (15). Over the limit the tool says how many seconds to wait; failed calls don't count (12 of 15). No SLA found (0). Not labelled beta (10). 0 + 5 + 15 + 12 + 0 + 10 = 42.\n\n### Schema \u0026 documentation: Diffbot +9\n\n- Diffbot (83): The Extract APIs have a public OpenAPI 3.1.0 file, version 1.1.0, with 13 operations, and the reference pages are generated from it. We read that file and one rendered page. The descriptions for Crawl, Knowledge Graph and Web Search were not read (25). llms.txt exists but is a short index with no Markdown twins of the docs pages found (5 of 10). The Analyze API page has sections on when to use it and when not to (17 of 20). Parameters are typed, `url` is the one required field and the file has 15 enums, but `fields` is a comma-separated string and the file defines no shared response schemas (10 of 15). The file carries 24 examples. It documents only 200 and 500, with separate docs pages for 401, 404, 429 and 457 (11 of 15). The path is versioned `/v3` and a dated changelog with RSS runs from 2015 to 15 June 2026 (15). All per the 9 October check, not re-read on 4 November (terms bar automated access to the site). 25 + 5 + 17 + 10 + 11 + 15 = 83.\n- PrintFriendly MCP server (74): Two tools with schemas in a public server card at /.well-known/mcp/server-card.json (25). llms-install.md in the repository; no llms.txt read (5 of 10). Clear descriptions, with 'What each tool does' on the docs page (17 of 20). Typed inputs (12 of 15). FAQ with the 401, limit and plan errors (12 of 15). Registry 1.0.1; no changelog (3 of 15). 25 + 5 + 17 + 12 + 12 + 3 = 74.\n\n## Score by category\n\n| Category | Weight | Diffbot | PrintFriendly MCP server | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 55 | 42 | Diffbot +13 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 83 | 74 | Diffbot +9 |\n| Agent ergonomics | 13% (16.2 this run) | 63 | 87 | PrintFriendly MCP server +24 |\n| Security \u0026 auth | 14% (17.5 this run) | 21 | 46 | PrintFriendly MCP server +25 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 40 | 40 | even |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 77 | 58 | Diffbot +19 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 68 | 49 | Diffbot +19 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **56.1 · C** | **57 · C** | |\n\n## Facts side by side\n\n| Fact | Diffbot | PrintFriendly MCP server |\n| --- | --- | --- |\n| Kind | HTTP API | MCP server |\n| Vendor | Diffbot Technologies Corp. | Print Friendly LLC |\n| Hosted endpoint | `https://api.diffbot.com/v3` | `https://mcp.printfriendly.com` |\n| Transports | HTTP | Streamable HTTP |\n| Auth | API key | API 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**PrintFriendly MCP server.** PrintFriendly's MCP server does two things agents need often, clean page reading and document export, with two well-annotated tools, published limits and errors that tell the agent what to do. It uses a plain API key, has no status page, and returns web pages with no injection guidance.\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### PrintFriendly MCP server\n\n1. Use read_page for clean Markdown instead of fetching raw HTML\n2. Each successful call counts as one document; failed calls don't\n3. On a rate-limit error, wait the seconds it gives\n4. Treat page content as untrusted\n\n## Questions\n\n### Which is better for AI agents, Diffbot or PrintFriendly MCP server?\n\nPrintFriendly MCP server and Diffbot score within a point of each other on agent readiness, 57 (C) and 56.1 (C). Diffbot leads on reliability, schema \u0026 documentation, maintenance \u0026 community and transparency \u0026 trust.\n\n### Do Diffbot and PrintFriendly MCP server need an API key?\n\nBoth need an API key.\n\n### Can an agent call Diffbot and PrintFriendly MCP server without installing anything?\n\nYes. Diffbot has a hosted endpoint at https://api.diffbot.com/v3 and PrintFriendly MCP server at https://mcp.printfriendly.com.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/diffbot-vs-printfriendly-mcp.json, and with the fewest tokens: https://www.anchorterminal.com/compare/diffbot-vs-printfriendly-mcp.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"diffbot\", \"b\": \"printfriendly-mcp\"}`.
