Codebase Memory MCP vs Nps

A side-by-side look at the Codebase Memory MCP and Nps MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.

Codebase 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.

Verdict: choose Codebase Memory MCP for knowledge & memory work as a local process; choose Nps for environment & nature as a local process. You can also run both side by side in one mcpServers block.

Tools & capabilities

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

Nps tools 6

  • list_parksList or search NPS parks. Filter by free-text query, state code (2-letter, comma-separated), or parkCode list. Returns full name, description, designation, states, GPS, address, official URL.
  • get_parkFetch a single park by parkCode. Returns full description, designation, activities, topics, address, contacts, operating hours, entrance fees, and image gallery.
  • list_alertsCurrent park alerts — closures, road conditions, weather warnings, danger advisories. Filter by parkCode or state.
  • list_campgroundsCampgrounds inside a park or state. Returns name, description, RV/tent capacity, amenities, reservation info, GPS.
  • list_things_to_doActivities recommended by the park service — hikes, ranger programs, scenic drives, ranger-led activities. Filter by parkCode or state.
  • nps_visitationNational park visitor statistics — how many people visited a park. Answers "how many people visited Yellowstone", "NPS visitation numbers", "annual visitors to Grand Canyon", "busiest national park", "park attendance by month". Monthly + annual recreation and total visitor counts from the NPS Visitor Use Statistics service (keyless). Pass a park name or 4-letter code (e.g., YELL, GRCA, GRSM) and a year, or system_total:true for the whole national park system. Example: {"park":"yellowstone","year":2023}.

Frequently asked questions

Codebase Memory MCP is categorized under Knowledge & Memory and uses a local stdio subprocess. Nps belongs to Environment & Nature and uses a local stdio subprocess. Pick Codebase Memory MCP for knowledge & memory work and Nps for environment & nature.

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.

Codebase Memory MCP is listed as free. Auth: no auth required. Nps 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 deusdata-codebase-memory-mcp and nps as separate keys in the same mcpServers object, and your assistant will call tools from either one.

On AllMCPs, Codebase Memory MCP has a quality signal of 73/100 (Great) with 8 views, 1 installs and 47,308 GitHub stars. Nps has 59/100 (Good) with 1 views, 0 installs and 0 GitHub stars.
