How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score →

Endpoint Security63
Transport & Reachability100
Schema Quality & AI Usability73
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 1310 tokens (~131/item across 10 items; 10 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management10
  • Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage97
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 90% of tool parameters carry a description.Partial

MCP tools · 10 exposed · ~1,277 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

Tool Tokens
adoption_stats ~99

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.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

extract_citation ~194

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.

NameTypeReqDescription
urlstringyesAddress of the page to read

No output schema declared.

No examples provided.

extract_citations ~161

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.

NameTypeReqDescription
urlsarrayyesAddresses to read, at most 50

No output schema declared.

No examples provided.

get_measurement_data ~71

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.

NameTypeReqDescription
datasetstringyesDataset URL or bare filename

No output schema declared.

No examples provided.

get_method ~55

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.

NameTypeReqDescription
namestring

No output schema declared.

No examples provided.

how_to_capture ~214

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.

NameTypeReqDescription
agentstringHow 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;…
browserstringTarget browser, if known.

No output schema declared.

No examples provided.

install_extension ~181

Install or uninstall the capture extension in Firefox or Chrome without a window, without a click and without administrator rights — the runnable file shapes and commands, not a store link for someone to press. 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. Firefox installs and removes in well under a second over its own control channel; Chrome fetches the signed store build itself. Also returns what the extension lets you do that this endpoint cannot, and the conditions under which installing on a machine is yours to decide.

NameTypeReqDescription
actionstringWhat you need. 'both' is the default and returns each direction — an install without its matching removal leaves a machine changed.
browserstringTarget browser. Omit for both.

No output schema declared.

No examples provided.

list_measurements ~69

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.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

open_work ~129

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.

NameTypeReqDescription
labelstringFilter 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.

No output schema declared.

No examples provided.

recommend_settings ~104

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.
