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
  • +5 more on the listing page

Obsidian Sync MCP tools 10

  • read_noteRead a note's markdown content by path
  • write_noteCreate or overwrite a note (replaces entire content)
  • edit_noteEdit a note without rewriting it — append, prepend (after frontmatter), or replace exact text
  • list_foldersList all folders in the vault with note counts — use to discover folder names
  • list_tagsList all tags in the vault with counts — use to discover tags before filtering
  • list_notesList notes with timestamps. Filter by folder, name, tag, or date. Sort by name or modified.
  • search_notesSearch note text for terms (OR, case-insensitive substrings); paths and frontmatter titles are searched first. Filter by folder, tag, or date. Returns paths with one context line each, never the note body, after a status line that states which CouchDB sequence the index is caught up with.
  • delete_noteDelete a note
  • move_noteMove or rename a note — works across folders, creates destination folders automatically
  • get_note_metadataGet frontmatter, tags, outgoing links, backlinks, size, and timestamps — navigate the knowledge graph
