Ephemeris MCP vs Server Everything
A side-by-side look at the Ephemeris MCP 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 Ephemeris MCP 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.

get_planetary_positionsReturns precise Tropical Zodiac positions for all planets, Sun, Moon, and chart angles.
Server Everything tools 16
echoEchoes back the input stringget-annotated-messageDemonstrates how annotations can be used to provide metadata about content.get-envReturns all environment variables, helpful for debugging MCP server configurationget-header-paramsReturns its region argument and the Mcp-Param-Region HTTP header it arrived in. Demonstrates x-mcp-header (a 2026-07-28 Streamable HTTP client mirrors the argument into the header) and JSON Schema 2020-12 input and output schemas.get-resource-linksReturns up to ten resource links that reference different types of resourcesget-resource-referenceReturns a resource reference that can be used by MCP clientsget-structured-contentReturns structured content along with an output schema for client data validationget-sumReturns the sum of two numbersget-tiny-imageReturns a tiny MCP logo image.gzip-file-as-resourceCompresses a single file using gzip compression. Depending upon the selected output type, returns either the compressed data as a gzipped resource or a resource link, allowing it to be downloaded in a subsequent request: during the current session for a 2025-era client, or for ten minutes at a minted URI on protocol version 2026-07-28.trigger-list-changedSends a notifications/<list>/list_changed for the tool, prompt or resource list. On protocol version 2026-07-28 it is delivered on each subscriptions/listen stream that asked for that list; a 2025-era client receives it unsolicited.trigger-log-messagesSends one log message at each logging level during the call. On protocol version 2026-07-28 only the messages at or above the level the request names in _meta (io.modelcontextprotocol/logLevel) are sent, and none if it names no level; a 2025-era client gets those at or above the level it set with logging/setLevel. Deprecated: logging is deprecated as of protocol version 2026-07-28.- +4 more on the listing page

Frequently asked questions
Ephemeris MCP 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 Ephemeris MCP 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.
Ephemeris MCP has no declared pricing — check the project's own site. 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 ephemeris-mcp and modelcontextprotocol-server-everything as separate keys in the same mcpServers object, and your assistant will call tools from either one.
