Unblink Tools (18)
read
Main content (`mode=article`, default) or whole page (`full`) as Markdown, paginated via cursor. `format=raw_html` returns the unreduced source (optionally scoped by a CSS `selector`) — the escape hatch for scripts/forms/SSR-embedded JSON that reduction strips; `format=text` returns visible plain t…
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Open WebSearch is categorized under Search & Data Extraction and uses a local stdio subprocess. In contrast, Unblink belongs to Search & Data Extraction using remote streaming HTTP/SSE transport. Select Open WebSearch when you need capabilities focused on search & data extraction and Unblink when you require tools for search & data extraction.
Cheap orientation: title, description, lang, heading outline, link/form/image counts, excerpt, semantic region map, plus `llms_txt`/`robots` presence hints. Also returns a `collections` inventory — auto-detected repeating record-sets (product lists, search results, table-like rows), each with a rea…
links
The page's links (text + absolute href), optionally filtered. `limit` defaults to 200 (cap 1000); `total`/`truncated` report the rest.
forms
The page's forms and their fields (name, type, required, options).
find
Matching text snippets with the heading path locating each.
site
A host's agent-facing metadata: robots.txt summary (allow/disallow for a browser agent, crawl-delay, sitemaps) + llms.txt content + whether llms-full.txt exists. Context only — never blocks a fetch.
click
match?, render? }
submit_form
Submits a form from the current page (cookies carried); returns a summary. Forms declaring `enctype=multipart/form-data` are encoded as multipart automatically; `files` attaches uploads (`{field, filename?, mime?, content \
controls
Non-link interactive controls (buttons, `role=button`, `onclick`/`tabindex`, submit/reset inputs, tabs, summaries), each with a stable CSS selector for `interact`.
interact
Dispatches an interaction at a selector and runs the page's JS so its handlers fire, then returns the updated page. `event` defaults to `click`, which emulates a **full primary-button press** (`pointerdown`→`mousedown`→focus→`pointerup`→`mouseup`→`click`) so press/pointer-based widgets (react-aria/…
data
Machine-readable structured data embedded in a page: JSON-LD (schema.org), HTML data tables (caption/headers/rows), and microdata (itemscope/itemprop). `kind` selects `jsonld`, `tables`, `microdata`, or `all` (default). HTML only. *(Tables: colspan and rowspan are expanded onto the real grid; micro…
extract
Caller-directed structured extraction with a CSS-selector schema: `fields` maps each output name to a selector (a string takes the element's collapsed text; `{selector, attr}` takes an attribute value instead). An optional `root` selector emits one record per matching container (e.g. `root="li.prod…
