Astronomy Oracle vs Server Everything
A side-by-side look at the Astronomy Oracle and Server Everything MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Astronomy Oracle for aerospace & astrodynamics work as a local process; choose Server Everything for other tools and integrations as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Astronomy Oracle when
- You need dedicated capabilities in the Aerospace & Astrodynamics domain.
- You prefer a local stdio subprocess transport.
- Its auth model fits you: No auth required.

lookup_object, search_objects, plan_session.
Choose Server Everything when
- You need dedicated capabilities in the Other Tools and Integrations domain.
- You prefer a local stdio subprocess transport.
- Its auth model fits you: No auth required.
- You want tools like
create_entities, create_relations, add_observations.

Tools & capabilities
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
Astronomy Oracle is categorized under Aerospace & Astrodynamics and uses a local stdio subprocess. Server Everything belongs to Other Tools and Integrations and uses a local stdio subprocess. Pick Astronomy Oracle for aerospace & astrodynamics work and Server Everything for other tools and integrations.
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.
Astronomy Oracle is listed as free. Auth: no auth required. Server Everything 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 gregario-astronomy-oracle and modelcontextprotocol-server-everything as separate keys in the same mcpServers object, and your assistant will call tools from either one.
