fetch

TinyFish Fetch

Free, token-efficient content extraction via the bundled TinyFish MCP server (fetch_content tool). Renders pages in a real browser and returns clean, structured content — actual page text, not a lossy summary — so it handles JavaScript-heavy and dynamic pages that raw HTTP fetching can't.

When to use this over built-in fetch

• It's free and returns clean, deduplicated content instead of raw markup, so it costs fewer tokens to read.
• It renders in a real browser, so it works on JS-heavy pages that a plain HTTP fetch would return empty or broken.
• It fetches up to 10 URLs in parallel in a single call — no need for repeated round-trips.
• Optional CSS-selector scoping (include_selectors/exclude_selectors) lets you pull just the content that matters and skip boilerplate, and conditional-request support (if_none_match/if_modified_since) avoids re-fetching unchanged pages.

Parameters

• urls (required) — 1-10 URLs, fetched in parallel; one failing doesn't block the others
• format — "markdown" (default, best for LLM consumption), "html" (cleaned semantic HTML), or "json" (structured document tree)
• links — include all outbound links from each page
• image_links — include all image URLs from each page
• include_selectors / exclude_selectors — arrays of CSS selectors to scope extraction to, or strip out before extraction
• if_none_match / if_modified_since — replay a prior ETag/Last-Modified validator (single URL only). Only works on the fast (non-browser-rendered) path — a browser-rendered URL may return conditional_unsupported; if so, retry without the validators.
• include_etag_and_last_modified — opt in to receiving validators on each result for future conditional requests
• per_url_timeout_ms — independent timeout budget per URL
• purpose — optional short note on why you're fetching, used to tailor extraction

Response includes per URL: url, final_url, title, language, author, published_date, text (and links/image_links if requested).

Examples

fetch_content(urls=["https://example.com/article"], format="markdown")

fetch_content(
  urls=["https://site-a.com/pricing", "https://site-b.com/pricing"],
  format="markdown",
  include_selectors=["main", "article"]
)

Escalating

If the page requires clicking, filling a form, or navigating before the content you need is reachable, use /tinyfish:agent instead — fetch only reads what's already on the page.
