Git vs Open Notify
A side-by-side look at the Git and Open Notify MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Git for other tools and integrations work as a local process; choose Open Notify for aerospace & astrodynamics as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Git 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.
Choose Open Notify when
- You need dedicated capabilities in the Aerospace & Astrodynamics domain.
- You prefer a local stdio subprocess transport.
- You want tools like
iss_now, astros.

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.
Git is listed as free. Auth: no auth required. Open Notify has no declared pricing — check the project's own site. 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 git and open-notify as separate keys in the same mcpServers object, and your assistant will call tools from either one.
