Claude Task Master vs Astronomy Oracle
A side-by-side look at the Claude Task Master and Astronomy Oracle MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Claude Task Master for developer tools work as a local process; choose Astronomy Oracle for aerospace & astrodynamics as a local process. You can also run both side by side in one mcpServers block.

Astronomy Oracle tools 3
lookup_objectLook up a celestial object by Messier number (e.g. M31), NGC/IC designation (e.g. NGC7000), or common name (e.g. Andromeda Galaxy). Optionally compute visibility from a given location and time.search_objectsSearch and filter the celestial object catalog by type, constellation, magnitude, angular size, or catalog membership. Returns a formatted table of matching objects sorted by brightness.plan_sessionGenerate an observing session plan for a given location and date. Returns the best celestial objects to observe grouped by time window (evening, midnight, pre-dawn), scored by observability.

Frequently asked questions
Claude Task Master is categorized under Developer Tools and uses a local stdio subprocess. Astronomy Oracle belongs to Aerospace & Astrodynamics and uses a local stdio subprocess. Pick Claude Task Master for developer tools work and Astronomy Oracle for aerospace & astrodynamics.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Claude Task Master is bring-your-own-key: usage is billed by the API provider you supply a key for. Auth: api key required. Astronomy Oracle is listed as free. Auth: no auth required. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add eyaltoledano-claude-task-master and gregario-astronomy-oracle as separate keys in the same mcpServers object, and your assistant will call tools from either one.
