"knowledge" matching MCP servers:

MCP server for LINDAS, the linked-data knowledge graph of the Swiss administration, enabling querying of Swiss public data cubes via guarded SPARQL tools.

Enables AI assistants to search, explore, and query any CKAN open data portal through natural language, making public datasets accessible without requiring knowledge of the portal's API.

Enables querying EU-funded research projects and ERC grants from the CORDIS knowledge graph, including full project records and ERC scheme listings, with server-side filtering and attribution.

Enables MCP clients to search verified Japanese corporate records — EDINET XBRL financials, 13-digit corporate numbers, major shareholders, and gBizINFO certifications — locally through a single knowledge-search tool with keyword, fuzzy, semantic, or hybrid retrieval. It also maps J-GAAP, US GAAP, and IFRS concepts so filings can be read in English without mistranslating terms like 営業利益 and 経常利益.

A money-in-politics knowledge graph, as an MCP server. It links entities across federal campaign donations, lobbying disclosures, and government contracts.

It also supports citation-validated drafting, deadline and docket monitoring, judgment deconstruction, OCR dossier compilation and legal knowledge-graph analysis for civil-law practice, teaching and research.

Provides agricultural intelligence tools for pest/disease lookup, government scheme discovery, and SME knowledge retrieval via semantic search.

Enables monitoring Migrationsverket's public legal position feed to detect when cited RS/RK documents have been superseded, so firms can identify which knowledge base entries are out of date.
