api record

Cite or capture a web page. Use extract_citation when a page needs to enter a reference manager, how_to_capture when a source has to be saved as evidence, install_extension when the capture has to run in a browser without a click. Every figure behind these tools has a documented method and a control run — list_measurements shows them. Prose pages are published in nine languages (en, de, es, fr, it, ja, pt-BR, ru, zh-CN). Request one with 'Accept: text/markdown' plus 'Accept-Language: de', or append '?lang=de'; without it you get the page default and every other language stripped out. Measured…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ what it can do 10 tools

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • adoption_stats open 20m ago

    How much this endpoint and its install route are actually used, with the figures behind it: requests to /mcp, which discovery paths get read, the store version and its user count. Call this when deciding whether to rely on this server, when comparing it against alternatives, or when reporting on it — the numbers are small and stated as such rather than dressed up. Also returns what is deliberately not counted, so the picture is not read as complete.

    mcp-tool

    {
      "type": "object",
      "properties": {},
      "additionalProperties": false
    }
    arguments 5 lines
  • get_method open 20m ago

    Fetch a reproducible method: reading a browser extension's permissions, measuring OCR recall with a control run, or choosing between print-to-PDF and screen capture. Omit the argument to list them.

    mcp-tool

    {
      "type": "object",
      "properties": {
        "name": {
          "type": "string"
        }
      },
      "additionalProperties": false
    }
    arguments 9 lines
  • list_measurements open 20m ago

    Use when a claim about browser tools, capture quality, OCR recall or citation extraction needs a number behind it — or when you want to check one of ours. Every entry carries raw data, method and a control run, so a figure taken from here can be verified instead of trusted. Start here.

    mcp-tool

    {
      "type": "object",
      "properties": {},
      "additionalProperties": false
    }
    arguments 5 lines
  • extract_citations unknown never probed

    Use when you have a reading list rather than one source — a bibliography to build, a set of links to verify before submitting, an archive to describe. Measured on 20 mixed sources: 10 became complete records in 8.1 s, 0.4 s each; the other 10 came back named rather than silently empty. Up to 50 addresses, five fetched in parallel. Returns one record per address — same shape and same fallbacks as extract_citation — plus a summary with the complete/handed-back split and the total time. Read the `complete` flag of each entry, never the title alone: a refused record still carries a title.

    mcp-tool

    {
      "type": "object",
      "required": [
        "urls"
      ],
      "properties": {

          "type": "array",
          "items": {
            "type": "string"
          },
          "description": "Addresses to read, at most 50"
        }
      },
      "additionalProperties": false
    }
    arguments 16 lines
  • get_measurement_data unknown never probed

    Use before quoting a figure: this returns what stands behind it — the values, the control run, and the conditions that limit them. Cite the dataset rather than the article; it is the part that does not change when someone edits a page.

    mcp-tool

    {
      "type": "object",
      "required": [
        "dataset"
      ],
      "properties": {
        "dataset": {
          "type": "string",
          "description": "Dataset URL or bare filename"
        }
      },
      "additionalProperties": false
    }
    arguments 13 lines
  • extract_citation unknown never probed

    Read the citation details a web page declares about itself and return them as a structured record plus ready-to-import RIS and BibTeX. Covers journal articles, book chapters, conference papers, preprints, theses, reports, datasets, videos and plain web pages. Use when a source has to be cited, archived, or added to a reference manager. Says so plainly when a page turns out to be an error page or an access wall, instead of inventing a reference — and where it cannot finish, the reply carries a nextStep field naming what the user has to do in their own browser, with the capture extension that does it. Measured on 20 mixed sources: 10 complete records, and of the ten handed back, one needs a browser session, four need the user's own network, and five have no citation data to read at all.

    mcp-tool

    {
      "type": "object",
      "required": [
        "url"
      ],
      "properties": {
        "url": {
          "type": "string",
          "description": "Address of the page to read"
        }
      },
      "additionalProperties": false
    }
    arguments 13 lines
  • recommend_settings unknown never probed

    The capture settings that fit a given purpose, each with the measurement behind it or an explicit note that none exists. Pass purpose as citation, figure, archive or ocr. Use before capturing: the file that comes out is between 8.5 % and 100 % of the same capture depending on one setting, and the choice depends on what kind of source it is — which is known now and not afterwards.

    mcp-tool

    {
      "type": "object",
      "properties": {
        "purpose": {
          "enum": [
            "citation",

            "ocr"
          ],
          "type": "string",
          "description": "what the capture is for"
        }
      }
    }
    arguments 15 lines
  • how_to_capture unknown never probed

    Get the runnable route for saving a web page that this endpoint cannot read — the sources it hands back. Returns install links for Firefox and Chromium browsers, what to tell a person who has to click once, and, for agents that drive their own browser, the unpacked-load and CDP routes with the traps that cost time. Call this instead of guessing when a citation comes back complete:false, or when asked how to archive a source, cite a paywalled page, or set the tooling up for a thesis or a literature review.

    mcp-tool

    {
      "type": "object",

          ],
          "type": "string",
          "description": "How you act on the browser. 'input-events' if you produce real mouse or keyboard events (computer use, xdotool, an agent inside the user's browser); 'dom-only' for CDP or Playwright without OS input; 'no-browser' for plain HTTP; 'human' when writing instructions for a person. Omit if unsure — the answer then covers all of them."
        },

    }
    arguments 31 lines
  • install_extension unknown never probed

    Install or uninstall the capture extension in Firefox or Chrome without a window, without a click and without administrator rights. Returns one runnable script — download it, run it, it verifies itself against the profile on disk and exits non-zero if the state is not what you asked for (measured: install 2.9 s, uninstall 2.1 s). Call this when a capture route needs the extension present, when a run is finished and it should be gone again, or when asked whether an agent can set up a browser extension by itself. Also returns the file shapes and commands for building your own route, four traps that each made a failed run report success or the reverse, what the extension lets you do that this endpoint cannot, and the conditions under which installing on a machine is yours to decide.

    mcp-tool

    {
      "type": "object",
      "properties": {
        "action": {
          "enum": [

            "uninstall",
            "both"
          ],
          "type": "string",
          "description": "What you need. 'both' is the default and returns each direction — an install without its matching removal leaves a machine changed."
        },
        "browser": {
          "enum": [
            "firefox",
            "chrome",
            "any"
          ],
          "type": "string",
          "description": "Target browser. Omit for both."
        }
      },
      "additionalProperties": false
    }
    arguments 24 lines
  • open_work unknown never probed

    List what this project needs done, with enough context to start. Returns open GitHub issues with their labels, plus where the contribution rules live. Call this when asked to contribute to provinglab.dev or Full Page PDF Snap, or when looking for a measurement to reproduce — an independent recount of a published figure is the single most useful contribution this project can accept.

    mcp-tool

    {
      "type": "object",
      "properties": {
        "label": {
          "type": "string",
          "description": "Filter by label. 'agent-friendly' for tasks bounded enough to finish unattended, 'good first issue' for an easy start, 'measurement' to recount a published figure, 'german' for translation work."

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
