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.

Cosmik logoCosmikAerospace & Astrodynamics · Remote HTTP/SSELive space data for AI agents - rocket launches, ISS passes, launch news. Free, no auth.52GoodAuth: not declaredCodebase Memory MCP logoCodebase Memory MCPKnowledge & Memory · Local subprocess (stdio)Code-intelligence engine that indexes a repo into a persistent knowledge graph — functions, classes, call chains, HTTP routes, cross-service links. 159 languages via tree-sitter + Hybrid LSP, sub-ms structural queries, 99% fewer tokens than grep. Single static binary, zero dependencies, 100% local. npx codebase-memory-mcp73GreatAuth: no auth required

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.

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

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.

On AllMCPs, Cosmik has a quality signal of 52/100 (Good) with 2 views, 0 installs and 0 GitHub stars. Codebase Memory MCP has 73/100 (Great) with 8 views, 1 installs and 47,004 GitHub stars.
