"A browser focused on stealth or privacy features" matching MCP servers:

Provides read-only query tools over OpenStreetMap data in PostGIS, enabling natural language queries for features, categories, and spatial analysis.

Provides free Chinese A-share stock data including real-time quotes, historical K-lines, market scanning, and multi-factor stock screening via BaoStock and Sina Finance APIs.

Enables interactive access to JAXA's satellite observation data (precipitation, land surface temperature, NDVI, elevation, soil moisture) via Claude, providing tools for point time series, dataset information, and area image generation.

Provides current weather alerts for specified locations to AI assistants through the Model Context Protocol.

Provides access to 27 UK government data sources and services, enabling queries about transport, business, healthcare, and more via natural language.

MCP server for querying the Central Bank of Brazil's 'Valores a Receber' (amounts to receive) service, providing read-only access to official data through natural language with a hosted server and prepaid credits.

Privacy-first OSINT scanning MCP server that aggregates ~25 sources into a risk report, running locally with no data leaving your machine.

MCP server for UNICEF child development statistics. Query 790+ child-focused indicators across 200+ countries with disaggregations by sex, age, wealth quintile, and residence. No API key required.

Enables interaction with the Polish National Register of Borders (PRG) data, currently providing health status monitoring and a server skeleton for future data retrieval features.

MCP server for Finnish public procurement notices (Hilma). Enables searching and retrieving procurement notices directly from Claude without a separate browser.

An MCP server for querying data on 27 million Brazilian companies from the Federal Revenue, enabling searches by CNPJ, company name, location, and industry. It supports advanced features like partner discovery, sector benchmarking, and similarity analysis.

MCP server for searching treks (hiking, mountain biking, horse riding, snowshoeing, etc.) on a GeoTrek instance via its public API, with geocoding via Nominatim. Exposes tools to search treks by duration, elevation, regulation labels, activity type, and proximity to a place or coordinates.

MCP server for discovering Madagascar-focused humanitarian, weather, risk, and open-data sources, with tools to search datasets, fetch alerts, and get weather information.

Gives AI assistants direct, on-demand access to McGill's public Visual Schedule Builder timetable data, letting them search course offerings, fetch sections and meeting times, check conflicts, and generate ranked schedule combinations without a login, API key, or browser session. Queries and schedule calculations run locally on structured results, with a short-lived cache for repeated requests.

Enables querying the 90 amateur ITU zones as the IARU publishes them, with each zone's ADIF DXCC and subdivision prefixes, boundary wording, and source citation, so users can find which zones cover a DXCC entity or subdivision, search zones by prefix or text, and check validity on a given date — all offline, without credentials.

Enables clients to look up DARC local-club DOK codes and special event DOKs — district, club, purpose, callsign and sponsoring club — and to check whether a code was valid on a given QSO date, or to search by club, town, district or purpose. Runs fully offline with no network or authentication, and every answer cites its published source.

Reconciles Wikidata items against OpenStreetMap features, yielding verdicts (matched, ambiguous, unmatched, error) based on existing wikidata tags, cross-lingual name agreement, and distance, with support for SPARQL selectors to define item sets.

Remote, read-only MCP connector to check any company's witnessed trust record on the Trooth Network, across identity, security, privacy, and AI practices. Also does a neutral read of a domain's public security surface and verifies signed Trust Ledger Tokens. No key, no account.

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.

Enables AI clients to query public US Department of Energy and national-laboratory data — research literature, datasets, software, patents, EIA grid and BPA operations, facilities, Daymet weather, climate models, sensors, and materials structures — through focused stdio servers. Every answer carries a provenance envelope naming the systems read, when they were read, and what the search did not cover.
