"How MCP Interacts with Blockchain Technology" matching MCP servers:

Enables searching public FERC eLibrary filings, retrieving docket sheets and filing metadata, and downloading public documents through any MCP client.

Enables querying the CNCF landscape to search for projects, get detailed information, GitHub metrics, maturity status, and case studies for technology decision support.

Hourly electricity grid carbon intensity (gCO2eq/kWh) for 45 zones across Europe, the US and Great Britain, computed from ENTSO-E, EIA and NESO generation data. Four read-only tools; every value carries its interval timestamp and how stale it is. No API key, no account.

Enables querying WikiTree genealogy data including profiles, ancestors, descendants, relatives, biography, photos, and categories via natural language.

Enables offline, millisecond querying of a locally built SQLite snapshot of TibiaWiki, letting an agent resolve approximate page names, filter creatures and items by stats and damage modifiers, and find how any item is obtained via drops, vendors, or quest rewards. Every response reports when the index was generated, and no network calls are made.

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.

MCP server for Korea's DART (Data Analysis, Retrieval and Transfer) electronic disclosure system, operated by the Financial Supervisory Service (FSS). Exposes company disclosures, company profiles, and financial statements via the OpenDART public API.

Central Bank of Russia (CBR) data for AI agents — daily and historical currency rates, key rate, inflation, and macro statistics. Five typed MCP tools, in-memory TTL cache, MIT-licensed, no API key required.

MCP server for Russian government procurement data that enables AI assistants to search tenders, get detailed cards, and analyze customer/supplier history.

Search source-linked enterprise AI deployments by company, industry, technology and reported outcomes, then retrieve supporting case details. This runnable stdio adapter connects to the hosted AIUseCaseHub MCP, with four live tools and a limited public preview requiring no API key.

Enables MCP clients to discover and aggregate upstream technology hotspots from multiple sources, offering tools to list sources and fetch trending items with filtering and error tolerance.

Provides AI agents with access to US patent data through 16 tools for search, citation analysis, technology trends, and portfolio comparisons via the free USPTO PatentsView API.

An MCP server that connects AI agents to over 200 tools across 27 Brazilian public APIs, covering economic, legislative, transparency, and judicial data. It enables users to query and cross-reference extensive government datasets from sources like IBGE, the Central Bank, and the Brazilian Congress.

A MCP server for data visualization. It exposes tools to render charts (line, bar, pie, scatter, heatmap, etc.) from data and returns plots as either image/text/mermaid diagram.

MCP server for the Russian state registries EGRUL (legal entities) and EGRIP (individual entrepreneurs), built on official Federal Tax Service open-data dumps. Self-hosted via local SQLite.

Enables AI agents to autonomously discover, stream, and compute satellite analytics from free government Earth-observation catalogs such as Sentinel-2, Landsat, and Copernicus DEM, with zero API keys or configuration. It supports place-name geocoding, STAC scene search, cloud-native COG streaming for spectral indices, elevation profiles, SAR flood detection, and sandboxed custom geospatial scripts.

MCP server for Russian Rosreestr open cadastral data — lookup by cadastral number, address or coordinates; cadastral value with history.

Enables access to Hong Kong government's official open data portal (DATA.GOV.HK) through natural language queries. Supports searching datasets, browsing categories, and retrieving detailed information about Hong Kong's public data resources.

Enables AI agents to autonomously discover, stream, and compute satellite analytics from free government Earth observation archives. Provides tools for STAC search, spectral indices, elevation profiles, SAR water detection, and sandboxed geospatial scripting.

Enables searching National Science Foundation award and funding data, including by award number, keyword, principal investigator, or institution, with no API key required.
