"Sky" matching MCP servers:

Provides deterministic computation of magnetic declination and sky positions (sun, moon, planets) for any location and time, enabling agents to get accurate ephemeris and geomagnetic data without hallucination.

A local, open-source MCP server that wraps astronomy data services (SIMBAD, JPL Horizons, VizieR, etc.) behind a conversational interface, enabling AI assistants to answer astronomy questions with real, typed, and provenance-tracked data.

A local MCP server for SkyPortal and Fritz that exposes astronomical transient data (photometry, spectra, classifications, observability) as tools for AI coding assistants.

Gives AI assistants read-only access to public astronomy archives (TNS, SIMBAD, VSX, Gaia, TESS, ZTF, Rubin and others) so a sky position or object can be checked in seconds for whether it is already known. It returns compact JSON verdicts with evidence, failed sources, image links, and tonight's observable unclassified transients.

Enables AI assistants to perform read-only checks of sky positions against public astronomy archives, returning compact JSON verdicts and evidence for known transients, variables, TESS objects, asteroids, and other objects, plus observation planning and image links.

Enables compatible assistants to access astrology tools through the public CosmyDay API, including natal charts, location lookup, horoscopes, moon phases, transits, and sky events.

MCP server for Common Thread that enables agents to drive the full investigation API, including creating investigations, managing seeds, ingesting data, attribution, and generating evidence packets.

Enables MCP clients to access quantitative investment research, factors, strategies, and portfolio capabilities through the official SKZ CLI.

An MCP server providing AI agents with access to satellite imagery, geospatial intelligence, and billing management through the SkyFi platform.

Enables natural language queries of astronomical data across multiple archives (Gaia, 2MASS, image holdings) via the Trillian platform, allowing users to search catalogs and find images by sky coordinates.

Enables AI assistants to work with Taranis NG OSINT platform through a typed, safety-oriented interface over its REST API, covering collection, analysis, reporting, and administration workflows.

Enables Zotero 10 library management via MCP, allowing search, metadata retrieval, annotation and collection management, and optional write operations (notes, tags, metadata, items) through a local Streamable HTTP endpoint.

MCP server for Brandwatch's Consumer Research, Data Upload, and Analysis APIs, exposing 55 tools for social listening, mentions, queries, alerts, and data uploads.
