get_overviewProvides a comprehensive overview of recent parliamentary activities, including the most recent documents and MPs celebrating birthdays today. The response contains structured data with two main sections: 'recentDocuments' (listing the latest parliamentary documents with their IDs, titles, types, dates, and URLs) and 'birthdays' (listing MPs celebrating birthdays today). The results are paginated with 10 documents per page. The tool supports iterative pagination - check the pagination.hasMoreDocuments field in the response to determine if additional pages are available. The response includes pagination information showing the current page, whether more documents are available, and the total number of documents retrieved. Applicable when general information about recent parliamentary activities is needed.birthdays_todayLists all Members of Parliament celebrating their birthday today, including their names, political parties, and birth dates. The response is a JSON array where each entry contains the MP's ID, name, party affiliation, and other details. This tool takes no parameters as it always returns today's birthdays. Applicable when information about MPs' birthdays is needed.list_personsProvides a complete directory of current Members of Parliament with their IDs, names, titles, party affiliations, and faction memberships. The response is a JSON array where each entry contains an MP's full details including unique MP IDs that can be referenced by other tools. This tool takes no parameters as it returns all current MPs. Applicable when comprehensive information about all MPs is needed or when analyzing the composition of parliament by party.search_tkPerforms a comprehensive search across all parliamentary data including documents, activities, and cases. Returns results matching the provided keyword or phrase. Use this for general searches when you need information on any topic discussed in parliament, regardless of document type or context. Search syntax: Searching for 'Joe Biden' finds documents containing both 'Joe' and 'Biden' anywhere in the text. Searching for "Joe Biden" (with quotes) finds only documents where these words appear next to each other. Searching for 'Hubert NOT Bruls' finds documents containing 'Hubert' but not 'Bruls'. The capital letters in 'NOT' are important. You can also use 'OR' and 'NEAR()' operators.search_tk_filteredPerforms a search within a specific category of parliamentary data, allowing results to be limited to only documents, activities, or cases. Returns paginated results sorted by date (most recent first). Search syntax supports: keyword searches ('Joe Biden' finds both terms), exact phrase searches ("Joe Biden" with quotes finds the exact phrase), exclusion ('Hubert NOT Bruls' excludes documents with 'Bruls'), and boolean operators ('OR', 'NEAR()'). Results can be returned in 'full' or 'summary' format.get_photoRetrieves the official portrait photograph of a Member of Parliament. Returns the image as a binary resource that can be displayed or saved. Use this when you need to include a visual representation of an MP in reports, presentations, or profiles.get_document_detailsRetrieves metadata about a parliamentary document in a structured JSON format, without downloading the actual document content. Returns information including title, type, document number, dates, version number, and links to both the PDF version and the official Tweede Kamer webpage.get_document_linksConverts document URLs into clickable markdown-formatted links. This tool takes either a direct PDF link or a Tweede Kamer webpage link and returns them as properly formatted clickable links.get_committeesRetrieves a list of all parliamentary committees with their IDs, names, and URLs. The response is a JSON array where each entry represents a committee with its unique identifier and name. Committees are specialized groups of MPs that focus on specific domains like defense, healthcare, or finance. This tool takes no parameters as it returns all active committees.get_committee_detailsRetrieves detailed information about a specific parliamentary committee, including its members, recent activities, and description. This provides deeper insight into the committee's composition, leadership roles, and recent work. Use this when you need comprehensive information about a particular committee's structure and activities.get_upcoming_activitiesRetrieves a list of upcoming parliamentary activities including debates, committee meetings, and other events. The response contains a structured JSON object with both a chronological list of activities and activities grouped by date. Each activity includes details like date, time, location, committee, type, and a URL for more information. The results are sorted by date with the most imminent activities first. The optional 'limit' parameter controls the number of results returned (default: 20, max: 100).get_voting_resultsRetrieves recent voting results on parliamentary motions and bills. The response contains a structured JSON object with voting results sorted by date (newest first). Each result includes detailed information such as the title of the motion/bill, the date of the vote, the submitter, whether it was accepted or rejected, the vote counts (for/against), and which political parties voted for or against. The 'limit' parameter controls the number of results (default: 20, max: 100) and 'format' parameter allows choosing between 'full' or 'summary' format. The 'summary' format provides a more structured representation with renamed fields, while both formats include complete party voting information.firecrawl_scrape
Retrieve and extract content from one supplied URL through Firecrawl. Use this when the request identifies a page and needs its content or defined fields. It can return markdown, HTML, links, screenshots, branding data, a targeted answer, or JSON matching a supplied schema; JSON is useful when the requested result has defined fields, while markdown preserves readable page content.
This tool operates on a known page. For a set of pages use `firecrawl_crawl`, and to discover page URLs use `firecrawl_map` or `firecrawl_search`. Options include JavaScript render delay, cache age, main-content filtering, PII redaction, and lockdown cache-only retrieval. Browser actions may change the live page when interactive actions are enabled.
Firecrawl may reuse recently indexed content instead of refetching the page, and the reuse window varies by domain. Set `maxAge: 0` to force a live fetch, or a smaller `maxAge` to bound how stale reused content may be. A successful response does not by itself confirm that the state it describes is still current.
Returns the selected content formats and page metadata.
firecrawl_map
Enumerate URLs indexed under one website through Firecrawl without fetching each page's content. Use this when the request asks for a site's URL inventory, when several relevant pages must be located, or when the desired page URL is unknown. An optional `search` term narrows the URL list, while sitemap, subdomain, query-parameter, and result-limit options control coverage.
Returns matching URLs rather than page bodies. Retrieve one page with `firecrawl_scrape`; collect content across multiple pages with `firecrawl_crawl`.
firecrawl_search
Search web, news, or image sources and return ranked results. Operators include quoted phrases, `-term`, `site:host`, `inurl:term`, `intitle:term`, and `related:host`; the set is non-exhaustive. `includeDomains` and `excludeDomains` are mutually exclusive hostname filters; categories limit results to GitHub, research, PDF, or developer sources.
For a programming question, add `categories: ["developer"]`. It searches an index of GitHub issues, merged pull requests, repository READMEs, and curated documentation sites, and returns the hits in `data.developer` beside the web results.
`categories: ["research"]` restricts these web results to research-affiliated websites and returns page snippets. The `firecrawl_research_*` tools are a separate surface that searches paper abstracts and full text across biomedical (PubMed, bioRxiv, medRxiv) and arXiv literature.
`scrapeOptions` can attach extracted page content; pages fetched this way use a fixed reuse window and ignore `maxAge`, so use `firecrawl_scrape` when a live fetch is required. Returns source-type result groups and usage metadata. Authenticated responses can include an `id` for optional search feedback.
Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.

firecrawl_crawl
Start a multi-page crawl at a website URL, poll it to a terminal state, and return the final status and collected data. Scope can be bounded with include/exclude paths, depth, page limit, subdomain/external-link controls, sitemap handling, delay, and scrape options.
Crawl results can be large; use conservative limits when full-site coverage is unnecessary. Webhooks and interactive scrape actions are unavailable in safe mode. Returns the crawl ID, status, and page data.
firecrawl_check_crawl_status
Retrieve the current status, progress, and available results for an existing crawl ID. This only reads Firecrawl job state and does not start or modify the crawl.
firecrawl_extract
Deprecated compatibility entry point. Use firecrawl_scrape once per known URL with formats: ["json"] and jsonOptions containing the prompt and schema. Use firecrawl_search or firecrawl_agent before Scrape when URLs are not known.
firecrawl_agent
Start an asynchronous web research job from a prompt, optional seed URLs, and an optional JSON schema. Use this for a requested synthesis across multiple sources when the task can wait for asynchronous completion. The agent can search, navigate, read pages, and assemble a structured result.
This call returns only a job ID, not the research result. Read the job with `firecrawl_agent_status` until it reaches `completed` or `failed`; research commonly takes several minutes. If the job cannot finish within the task's available time, `firecrawl_search` and `firecrawl_scrape` can gather evidence synchronously.
firecrawl_agent_status
Retrieve progress or final results for a `firecrawl_agent` job ID. A `processing` response is non-terminal and does not contain the final research result. Check again after 15–30 seconds until the status is `completed` or `failed`; complex jobs can take several minutes. If the job cannot finish within the task's available time, use `firecrawl_search` and `firecrawl_scrape` to complete the requested output.
Returns job status, progress information, and result data when completed.
firecrawl_interact
Open or reuse a live browser session to navigate a page, click controls, fill fields, or run browser code. Provide either `url` or `scrapeId`, and either a natural-language `prompt` or executable `code`; code can run as Bash, Python, or Node with a bounded timeout.
This acts on the live site, so actions such as form submission can create persistent external side effects. Returns execution output, stdout/stderr, exit status, and session viewing URLs.
firecrawl_interact_stop
Stop the live interact session associated with a `scrapeId` and release its resources. Returns a success confirmation.
firecrawl_parse
Parse one supported document into markdown, HTML, links, summary, targeted answers, or JSON matching a schema. Supported inputs include common HTML, PDF, Word, RTF, OpenDocument, and spreadsheet files; PDF parsing can be bounded with `pdfOptions.maxPages`.
Local MCP reads `filePath` from the server filesystem. Hosted MCP uses two calls: first provide `filePath` to receive upload instructions, upload locally, then call again with the returned `uploadRef`; do not send both fields together. Remote web URLs belong in `firecrawl_scrape`.
Set `redactPII` to request redaction of personally identifiable information in the returned content. `zeroDataRetention` requires an eligible authenticated account; omit it for anonymous keyless use. Returns upload instructions for hosted phase one or parsed document content for the final call.
firecrawl_monitor_create
Create a recurring scrape, crawl, or search monitor that compares each check with its retained predecessor. The simple form accepts `page`/`pages` or `queries` plus a plain-language `goal`; the advanced `body` form controls targets, schedule, change-tracking formats, judging, retention, webhook, and notifications.
In the simple form, a `goal` is required. If `queries` contains one or more non-empty values and is supplied with `page`/`pages`, `queries` create the search target and page targets are ignored. A monitor schedules future network checks and can send configured email or webhook notifications. Returns the created monitor.
