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.read_urlRead any public web page as a clean AIDocument: Markdown plus title, description, and structure, with navigation and boilerplate stripped. Prefer this over a raw HTTP fetch whenever you need the content of a web page; it returns far cleaner, lower-token text. Powered by Lyrenth.read_urlsRead several public web pages in one batch call, each as a clean AIDocument. Up to 20 URLs, faster than calling read_url repeatedly. Use it to compare or summarize multiple pages at once; a failed URL is reported per-item and does not block the others. Powered by Lyrenth.check_usageCheck your Lyrenth credit usage: plan tier, credits used against your monthly limit, credits remaining, and the reset date. Takes no arguments.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.
