Tools (10)
| Name | Description | Schema |
|---|---|---|
fetch_markdown | Fetches one public HTTP/HTTPS page and returns its primary readable content as Markdown. Use this for article or documentation body text without page chrome. It does not run JavaScript; use a browser | typed |
inspect_url | Resolves a public URL through bounded redirects and returns status plus a safe allowlist of HTTP headers. Use HEAD for cheap reachability/type checks and GET when a server mishandles HEAD. Use extract | typed |
extract_metadata | Fetches one public HTML page and extracts title, description, canonical URL, robots directives, Open Graph, Twitter Card, advertised feeds, and parsed JSON-LD. Use this when an agent needs page identi | typed |
extract_links | Fetches one public HTML page and returns unique normalized HTTP/HTTPS links with anchor text, rel values, and same-origin classification. Use this for bounded navigation discovery; it does not crawl t | typed |
parse_feed | Fetches and normalizes RSS 2.0, Atom 1.0, or JSON Feed into a stable item list. Use this when consuming update feeds without format-specific parsing. It does not fetch linked articles. Limit: 8 s, 5 r | typed |
parse_sitemap | Fetches one uncompressed XML sitemap and returns either URL entries or child sitemap references. Use this for site structure discovery. Sitemap indexes are not recursively expanded; call this tool on | typed |
inspect_robots | Fetches an origin's robots.txt and evaluates one path for a named user agent using longest-match allow/disallow precedence. Also returns crawl delay and declared sitemaps. Use this before automated re | typed |
html_to_markdown | Converts supplied HTML into readable Markdown without fetching a URL. Use this when the agent already has HTML. Provide base_url only to resolve relative links; use fetch_markdown when Plainport shoul | typed |
diff_text | Computes a deterministic line- or word-level diff and returns typed add/remove/equal parts. Use this when an agent needs structured change data. Split highly divergent large documents if the computati | typed |
validate_json_schema | Validates a JSON value against a supplied JSON Schema using draft 4, 7, 2019-09, or 2020-12. Use this to verify generated or extracted structured data. It performs validation only and does not mutate | incomplete |
