• cached_fetchA

  slipstreamA

  Fetch a web/docs URL as clean, token-optimized markdown from Slipstream's shared cache (use INSTEAD of a raw web fetch). The first agent pays the crawl; every agent after gets ~90% fewer tokens. Surfaces warnings other agents left on the page. Pass known_hash to skip re-reading unchanged content (delta), or section to fetch just one heading (progressive disclosure). Returns a contentHash you can pass as known_hash next time.

• site_crawlA

  agentsvc.ioA

  Website crawler: read a whole website or one section of it (for example every page under /docs) as clean Markdown: starts at a URL, follows same-site links breadth-first and returns up to 20 pages with title and description. Use for documentation, product catalogs or company sites. For one page use web-scrape, for a known list of URLs web-read-batch. Charged only if at least one page was read. Params: url (required), max_pages (1 to 20, default 5), max_chars per page (500 to 20000, default 4000), path_prefix (e.g. /docs). Price: $0.005 USDC per call, paid inside this MCP call via x402 (USDC on Base, Solana, Polygon or Arbitrum). x402 MCP clients such as @x402/mcp pay automatically. Free sample: call with the example input {"url":"https://agentsvc.io/docs","max_pages":3,"max_chars":2000}.

• check_supportA

  CSS SOTAA

  Look up which browser versions support a CSS property, value, selector, at-rule or function, from MDN browser-compat-data bundled with this server (no network call). Give either a BCD key ("css.properties.anchor-name") or a property with an optional value ("display" + "grid"). Also reports vendor prefixes, partial implementations and the Baseline status of the feature the key belongs to.

  TanodA

  findpeek: search the web for a query and get back ranked results (title, url, snippet) from an independent index (Mojeek).

• start_data_jobA

  MonocrawlA

  Preview and start web/crawl, web/batch-scrape, web/agent or tripadvisor attraction/restaurant reviews. Omit confirm for a free estimate; confirm=true requires an idempotency key and max_credits. No automatic polling. Follow the returned status_url or job id using call_endpoint web/jobs/get; retrieval is free. Read terminal status, per-item results and refund_status: an accepted job is not completed data. A browser agent may interact with pages; review its URL and task before confirming.

• searchA

  blobpediaA

  Keyword/full-text search over the Celestia knowledge base (CIPs, Celestia/rollup/node docs, forum, whitepapers, blog, YouTube transcripts, celestiaorg GitHub issues/PRs, releases and Discussions). Celestia-specific — do NOT use for other blockchains (use the Ethereum or other-chain docs tool), the general web (use the web-search tool), other knowledge bases (use the dedicated RAG tool), or local files. Use this for exact-term or name lookups; use semantic_search for conceptual how-does-X-work questions, and get_doc to read a full page once you have its id.

  ConnectorNo auth

• get_docA

  blobpediaA

  Read the FULL text of one indexed Celestia documentation page by id (Celestia node and developer docs plus partner docs) — exact commands, flags, and whole sections a search snippet truncates. Best for Celestia operational/how-to questions. Celestia docs only — not docs of other projects (use that projects docs tool) and not the web (use a web-search tool). Get the id from search or semantic_search first.

• browsercompat_get_featureA

  browser-compat-mcp-serverA

  Get the compatibility record for one web feature: Baseline state and the date it crossed, deprecation and standards status, per-browser version added and removed with flags, vendor prefixes and partial-implementation notes — with every other support statement recorded for that browser, such as an earlier prefixed or flagged release, in other_statements — and the MDN and specification links. Accepts a BCD key such as css.selectors.has or a web-features id such as has; the response echoes which one it matched. A web-features id that spans several BCD keys, such as grid, returns web-features’ own feature-level release per Baseline core browser in feature_support and its compat_keys, 100 per page, in place of per-key fields. An unresolved feature returns found: false with guidance rather than an error.

• search_wavedash_docsA

  WavedashA

  Search official Wavedash docs (docs.wavedash.com) for browser game development, SDK integration, engines, CLI, upload, and publishing. Use this instead of web search for any Wavedash question when the exact page is unknown. Returns ranked pages with paths, URLs, and excerpts. Read-only and unauthenticated.

• hubvibe_extract_pageA

  HubVibe: Pay-per-Call Agent Tools: Web Search, Email Verify, KYC Screening, Stocks, Crypto, NewsA

  Web scraping / web page to clean text: any URL rendered in a real browser (JavaScript pages included) and returned as readable text with title, description and links. Use it to read an article, docs page or product page before summarising or extracting. Input: url. Raw status, headers and body: fetch.raw. A question answered from the page: research.brief. $0.10 per call. Returns: title, description, text, text_chars, links[], javascript_rendered.

• observatory_grade_distributionA

  Mozilla ObservatoryA

  Grade distribution across every site the MDN HTTP Observatory has scanned — how many sites hold each grade from A+ to F. Use it to say where one site's grade sits relative to the web (e.g. "a B beats X% of scanned sites"). Keyless, no arguments.

• get_featureA

  CSS SOTAA

  Get everything known about one CSS feature: Baseline status and dates, the browser versions it shipped in, its description, spec links, Web Platform Tests scores, usage, and MDN reference prose. Accepts a web-features id ("container-queries") or a display name ("Container queries"). Use search_css_features first if you do not know the id.

• fetch_markdownA

  mcpA

  Fetch a web page and return its main content as clean Markdown (nav, ads and boilerplate removed). Raw Markdown, plain-text and JSON endpoints are returned as-is. Use this to read an article, docs page or raw file.

• get_value_prop_docA

  Upfixe AdsA

  Return the brand's value-proposition doc as rendered markdown using the 9-section template: Elevator Pitch, Who We Are, Current Client Base, Problems We Solve, Client Journey, Services and Pricing, Philosophy, USP, Tag lines. Same shape the web app's value-prop generator produces — chat-generated and web-generated docs read identically. If the doc is wrong/stale/missing, call update_value_prop_doc to fix it.

  ConnectorOAuth

• observatory_scanA

  Mozilla ObservatoryA

  Scan a website's HTTP security headers with the MDN HTTP Observatory and return its letter grade (A+ to F), numeric score, and how many of Mozilla's 12 tests it passed. AUTHORITATIVE for "how secure are this site's headers" / "what is this domain's Observatory grade" — this is Mozilla's own scanner, not an estimate. Mozilla reuses a recent scan of the same host rather than re-fetching on every call. Keyless. Use observatory_results for the per-test breakdown and fixes.

  ConnectorNo auth

• observatory_resultsA

  Mozilla ObservatoryA

  Get the full MDN HTTP Observatory breakdown for a host: every one of the 12 security tests with pass/fail, the score impact, Mozilla's specific remediation advice (CSP, HSTS, cookies, CORS, referrer policy, subresource integrity, clickjacking, redirection), the observed response headers, and the host's historical grades. Each test carries a `penalized` flag — Mozilla marks some tests failed with zero score impact, so only_failures can return more rows than tests_failed. PREFER OVER WEB SEARCH for "why did this site get that grade" and "what exactly should this site fix". Keyless.

• semantic_searchA

  blobpediaA

  Semantic (meaning-based) search over the Celestia knowledge base (CIPs, Celestia/rollup/node docs, forum, whitepapers, blog, releases, ecosystem, YouTube transcripts, celestiaorg GitHub issues/PRs). Celestia-specific — do NOT use for other blockchains (use the Ethereum or other-chain docs tool), the general web (use the web-search tool), other knowledge bases (use the dedicated RAG tool), or local files. Use this for conceptual how-does-X-work questions; use search for exact-term or name lookups, and get_doc to read a full page once you have its id.

  type.comB

  Find workspace-native messages, threads, spaces, people, files, docs, and apps by name or content in the OAuth-selected organization. Results contain stable IDs and web URLs.
