Cosmik vs Codebase Memory MCP
A side-by-side look at the Cosmik and Codebase Memory MCP MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Cosmik for aerospace & astrodynamics work over a hosted endpoint; choose Codebase Memory MCP for knowledge & memory as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Cosmik when
- You need dedicated capabilities in the Aerospace & Astrodynamics domain.
- You prefer a remote HTTP/SSE transport.
- You want tools like
get_next_launches, get_iss_passes, get_launch_news.
Choose Codebase Memory MCP when
- You need dedicated capabilities in the Knowledge & Memory domain.
- You prefer a local stdio subprocess transport.
- Its auth model fits you: No auth required.
- You want tools like
index_repository, search_graph, query_graph.

Tools & capabilities
Cosmik tools 3
get_next_launchesLive schedule of upcoming orbital rocket launches (SpaceX, NASA, Rocket Lab, ULA, Arianespace, China…) with liftoff times (UTC), pads, status and a live-tracking link. Optionally filter by provider/rocket name.get_iss_passesWhen the International Space Station will pass over a location in the next 3 days: start time (UTC), maximum elevation, duration, and whether the pass is in a good viewing window (evening/pre-dawn). Provide a city name OR latitude+longitude.get_launch_newsLatest rocket-launch news articles (previews and post-launch recaps) from Cosmik, optionally filtered by a search term (mission, rocket, or provider name).
Codebase Memory MCP tools 17
index_repositoryIndex a repository. full/moderate add semantics; fast omits them; cross-repo-intelligence links services. Reports coverage gaps.search_graphFind symbols via BM25 query, regex name/qn filters, or semantic_query. Rows keep qn/file/lines and in/out over CALLS/USAGE/CALL_REFERENCE/INHERITS/IMPLEMENTS.query_graphRead-only Cypher for multi-hop, aggregation, complexity, or cross-service analysis. Default: 200 visible rows with exact/lower-bound totals and truncation; continue safely with next_cursor. graph=missed is a file tree of flagged coverage gaps; absence is not proof of completeness. Use get_graph_schema(diagnostics=full) for properties.trace_pathTrace callers/callees, data flow, or cross-service paths. Defaults exclude tests and resolver evidence. Rows keep qn/hop with explicit totals, relations, and continuations.get_code_snippetRead a search_graph symbol. auto bounds source and outlines large containers; full restores up to 500 lines. Source/outline pages continue; coverage_note marks gaps.get_file_outlineDeclaration outline of one exact repository-relative file: optional exact label filter, source order, exact total/offset/limit paging; file/folder/container nodes excluded.get_graph_schemaGet node-label and edge-type counts. diagnostics=full also lists queryable properties.compare_graphsCompare two indexed snapshots: deterministic target-only additions and base-only removals of stable node/edge identities; each set capped by limit and a 512 KiB budget with exact totals and truncation reasons.get_architectureCompact counts, languages, packages, entry points. Request structure, dependencies, routes, hotspots, boundaries, layers, clusters, cycles, or file_tree; path scopes a directory.search_codeGraph-ranked text search: compact symbols, full bounded source, or file paths.list_projectsList projects with stable paging. Identity is lean; stats adds graph sizes.delete_projectDelete a project from the index- +5 more on the listing page

Frequently asked questions
Cosmik is categorized under Aerospace & Astrodynamics and uses a remote HTTP/SSE transport. Codebase Memory MCP belongs to Knowledge & Memory and uses a local stdio subprocess. Pick Cosmik for aerospace & astrodynamics work and Codebase Memory MCP for knowledge & memory.
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.
Cosmik has no declared pricing — check the project's own site. Codebase Memory MCP 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 cosmik and deusdata-codebase-memory-mcp as separate keys in the same mcpServers object, and your assistant will call tools from either one.
