Read-only MCP server for Energinet's public Energi Data Service. Enables dataset search, arbitrary dataset queries with filters, and CO2 emissions retrieval for DK1/DK2 without an API key.

Independent latency and uptime data for 46 hosted AI inference APIs, probed every 5 minutes from 4 regions with no gateway, plus a verified model deprecation calendar and Claude Code / Codex speed and accuracy drift. Four read-only tools, no API key; data CC BY 4.0.

Enables querying Red Hat security data including CSAF advisories, CVEs, and OVAL streams through natural language.

Gives Claude direct access to the Africa API for comprehensive data on all 54 African nations, including economic indicators, markets, trade, government, elections, and policies.

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.

Enables AI assistants to discover, query, and analyze official Census Bureau datasets and statistics, including geography lookup and aggregate data retrieval.

Connects AI assistants with official Census Bureau statistics, enabling dataset discovery, geography FIPS resolution, and aggregate data retrieval from the Census Data API and a local Postgres database.

Enables AI assistants to query official Census Bureau statistics by listing datasets, retrieving geographies and aggregate data, and resolving geographic names to FIPS codes through natural-language interactions.

Connects AI assistants with official Census Bureau statistics and data from the Census Data API and other official sources, enabling users to list datasets, fetch geography and aggregate data, resolve FIPS codes, and retrieve population statistics through natural language.

Enables AI assistants to discover Census datasets, resolve geography FIPS codes, and fetch aggregate statistics from official Census Bureau APIs and local data.

Enables AI assistants to query official Census Bureau statistics and metadata, including dataset listings, geography levels, aggregate data, and FIPS code resolution. It also provides prompts for retrieving population data for states, counties, cities, and other geographic areas.

Provides crystal structure generation, inspection, and export tools via MCP, supporting vacancy, interstitial, doping, solid-solution, surface, grain-boundary, interface, stacking-fault, and dislocation generators with deterministic outputs and optional Materials Project integration.

Enables AI assistants to discover and query official Census datasets, resolve geographic names to FIPS codes, and fetch aggregate population and demographic statistics for states, counties, cities, and other areas.

Enables AI assistants to access official Census Bureau statistics through the Census Data API and other official sources, supporting dataset discovery, geography resolution, FIPS lookup, and aggregate data retrieval.

Provides observed-only access to Australian Bureau of Statistics data series, enabling search, description, and retrieval of data with validated selection options for invalid requests.

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.

Enables AI assistants to discover official datasets, resolve geographic identifiers, and retrieve demographic and statistical data from official U.S. census sources.
