"Common Lisp" matching MCP servers:

A read-only MCP server for querying U.S. K-12 academic standards via the Common Standards Project API.

MCP server for the CrawlGraph backlink-intelligence API. Gives any MCP client - Claude Desktop, Claude Code, Cursor, Cline, Zed, Windsurf - backlink lookups and competitor gap analysis built on the public Common Crawl webgraph (4.4B edges, 120M domains).

MCP server that exposes skills from the Brazilian National Common Curricular Base (BNCC) with thematic units, knowledge objects, and prioritization layer from Mapa de Foco, enabling lookup, search, listing, and statistics of educational skills.

MCP server and CLI for querying Common Crawl via AWS Athena, enabling users to check a domain's presence in crawls, analyze dynamics, compare domains, and inspect page text.

An MCP server that integrates AI retrievals with NASA's Common Metadata Repository (CMR), allowing users to search NASA's catalog of Earth science datasets through natural language queries.

Enables natural language search and discovery of open-access scientific datasets through the EOSC Data Commons OpenSearch service. Provides tools to search datasets and retrieve file metadata using LLM-assisted queries.

MCP server for querying the Norwegian Brønnøysundregistrene business register, including companies, roles, subunits, and annual accounts, with built-in guards against common data traps like retired NACE codes and withheld employee counts.

Enables agents to retrieve the closest archived snapshot of a URL with extracted page text, and to query the complete capture history for a URL, prefix, host, or domain, with fallback to Common Crawl.

Enables queries about global taxonomic data, including scientific name matching, classification chains, common names, and synonyms from the Catalogue of Life index.

Enables backlink intelligence on the public Common Crawl webgraph, providing referring domains, gap analysis, outreach targets, and domain change tracking.

Provides access to U.S. labor market data including employment statistics, Consumer Price Index inflation rates, and wage information. Users can query specific time series data or use shortcuts for common economic indicators like unemployment and industry-specific employment.

Enables MCP clients to read-only access the Virginia General Assembly's sessions, bills, summaries, full text, history, votes, members, committees, and meetings via the LIS REST API.

Exposes materials-science data, simulations, workflows, and computing capabilities to MCP hosts through a plugin-agnostic, contract-governed engine with progressive capability discovery, bounded context, scoped permissions, and provenance-traceable artifacts. Concrete integrations such as a real OPTIMADE provider plugin stay separately packaged, so servers remain focused and evidence-backed rather than unrestricted.

A Wikimedia Commons MCP server enabling search, file metadata retrieval, category browsing, and random image selection through natural language.

Enables AI agents to query and retrieve public statistical data from Data Commons through search and observation tools. Provides access to demographic, economic, and other statistical indicators for analysis and research.

Enables agents to retrieve, submit, critique, and verify structured knowledge records with provenance, uncertainty, and references over a public federated HTTP/MCP layer.

Enables AI agents to retrieve free, source-linked decision methods and optional decision packs through MCP tools such as catalog, method, sample_pack, and pack_offer. It operates without model calls and disables payments by default.
