jDocmunch MCP

Index a local folder containing documentation files (.md, .txt, .rst; plus .pdf/.docx/.pptx/.epub when the optional [office] extra is installed — converted to Markdown locally). Parses by heading hierarchy into sections for efficient retrieval. An already-indexed source is recognized before storage is chosen: the established handle is reused (or refreshed), an explicit conflicting name returns a conflict instead of creating a duplicate index, and multiple equivalent legacy indexes return bounded ambiguity. Embeddings auto-enable when a provider is configured (GOOGLE_API_KEY, OPENAI_API_KEY, openai-compatible + JDOCMUNCH_OPENAI_COMPAT_URL + JDOCMUNCH_OPENAI_COMPAT_MODEL, or sentence-transformers). Coverage: `coverage_complete` answers 'did I get everything', with `skip_counts` / `skipped_paths` naming what was dropped and why; `truncated` answers ONLY the max_files cap and is false when a file was dropped for any other reason. Files over the per-file size cap (5MB default, JDOCMUNCH_MAX_FILE_SIZE) are reported under skip_counts.oversize. Response includes a `changes` list with one {doc_path, status: new|changed|deleted, mtime} entry per file, sorted newest first and capped at 50 entries, useful for a 'recently edited' map at session start. `changes_total` is the uncapped count and `changes_truncated` is true when entries were dropped. Deleted files sort last, so the cap drops them first: the `new`/`changed`/`deleted` count fields are the authority, not the length of `changes`.

Return the version-current CLAUDE.md / AGENT.md policy snippet for jdocmunch-mcp. Lets an agent keep a one-line CLAUDE.md (e.g. "Call jdocmunch_guide and strictly follow its instructions.") instead of pasting a static snippet that drifts from the installed version. Idempotent, no repo context required. Sibling of jcodemunch_guide.

Best-effort bridge from doc code blocks to jcodemunch code symbols. For each block, tokenizes identifiers and looks them up via jcodemunch's search_symbols. Returns {by_block, by_symbol, _meta} where _meta.bridge_available reports whether jcodemunch-mcp is importable.

v1.55+ — flat per-doc inventory of an indexed repo: doc_path, section_count, format, byte_size for each indexed document. Lighter than get_toc_tree (which returns full section trees per doc). Sorted by doc_path. Inventory only; it returns no section titles and no content.

Return every operation whose tags list contains the given tag (exact). Convenience wrapper around find_endpoint with only a tag filter.

List defined repo groups (v1.26+). Each group is a named alias for a set of indexed repos that search_sections can fan out across via the repo_group kwarg. Lists the group definitions only; it does not check that every member repo is still indexed.

List glossary terms in alphabetical order, optionally filtered by prefix. Capped at max_results (default 100).

Glossary lookup. Returns every entry whose term equals the query (case-insensitive, exact). Glossary entries are extracted at index time from **Term** — definition Markdown patterns and RST .. glossary:: blocks.

Map a jdocmunch docs repo to candidate jCodeMunch code repo handles by source_root. The two suites use independent repo-identity models, so a docs handle (e.g. 'local/foo-docs') is NOT a valid jCodeMunch code_repo. Given a docs repo, returns candidates[{repo, confidence, reason, source_root}] (exact source_root match = high; containment = medium/low), an 'ambiguous' flag, and _meta.bridge_available. Use it to pick the right code_repo for the link_code_to_symbols / get_undocumented_symbols bridge tools.

Search sections by relevance. Hybrid (BM25 lexical + semantic embedding) fusion when the index was built with use_embeddings=true; falls back to lexical-only otherwise. Returns summaries only — use get_section for full content.

v1.57+ — fast title-only token-overlap match. Different from search_sections (full hybrid retrieval). Use for navigation: 'find the section whose heading text matches X'. Handle-only output ({id, title, level, doc_path, _score}); no content reads, no embeddings.

v1.37+ — return prev/next siblings (in document order), parent, and first child for a section. Handles only (id, title, level, doc_path) — no content. Use for fast sequential navigation without re-querying search_sections.

Online weight tuning. Reads ranking_events from ~/.doc-index/telemetry.db (requires JDOCMUNCH_PERF_TELEMETRY=1) and proposes a per-repo semantic_weight step. dry_run=true skips the disk write. min_events gates against early overfitting. Learns from a recency window of the ledger (default 90 days) so stale events can't anchor the weights. Learning compares confidence WITH vs WITHOUT the semantic channel, so a workload that only ever runs one mode produces no signal at all — use set_weight there instead of waiting.

Byte-offset integrity check. Walks every section, byte-range-reads the bytes, recomputes SHA-256, and compares to the stored content_hash. source='cache' (default) checks the INDEX MIRROR: a clean result proves the index is internally consistent, NOT that the source document is still current. source='live' checks the real workspace files under the index source_root, so an edited source drifts and a deleted one goes missing. _meta.verify_layer always names which one ran. Reports drift / missing / error counts plus the drifting section ids. Sample N sections via the sample arg for cheap CI checks.
