Filesystem/git-native MCP knowledge gateway: an Obsidian vault + code-graph and doc-to-markdown tools, served over MCP.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
list_vaultsList the vaults available here, each with a short description.
list_notesList markdown note paths (vault-relative) within a vault.
read_noteRead one markdown note's raw content.
list_attachmentsList attachment files (images, PDF, audio, video) in a vault, vault-relative.
read_attachmentRead a binary attachment: an image returns as an inline Image; other types (PDF, audio, video) return as an embedded resource carrying the file's real media type. Refuses non-attachment paths and files over the 25 MiB cap.
list_canvasesList Obsidian .canvas files in a vault, vault-relative.
read_canvasRead an Obsidian .canvas file as parsed JSON: nodes (type 'group' = a group), edges, and 'color' fields.
write_canvasWrite an Obsidian .canvas file. `canvas` is the full JSON object: `nodes` (each with id/type/x/y/width/height; type 'group' is a group, 'color' sets the color) and `edges`. Optionally git-commit.
searchSearch a vault with ripgrep — literal by default, regex when regex=true.
backlinksFind notes that [[wikilink]] to the given note.
list_tagsList inline #tags in a vault with occurrence counts.
list_graphsList the built code graphs available for a vault (under .graph/), each with its counts and the revision its snapshot was built from.
graph_querySearch a built code graph by node id/label; returns matching nodes, highest-degree first.
graph_neighborsNeighbours of a node up to `depth` hops (direction: in|out|both) - related nodes + edges.
god_nodesThe most-connected nodes in a code graph (architectural hot-spots).
graph_shortest_pathShortest path between two nodes in a code graph.
graph_statsMetadata for a built code graph: counts, communities, and the `provenance` of the snapshot - the revision it was built from, when, and whether the file still matches the manifest. A graph is a snapshot; treat a mismatch or a missing manifest as unknown freshness, not as fresh.
convert_to_markdownConvert a document in the vault to Markdown text: PDF, Office, image, HTML, CSV, EPUB, Outlook message, audio or video. Refuses any other type (`not_convertible`), hidden and out-of-vault paths, and files over 50 MiB.
git_statusShow uncommitted changes scoped to the vault's subdir.
write_noteAtomically write a note; optionally git-commit the change.
git_commitCommit the vault's pending changes (scoped to its subdir).
patch_noteInsert content into a note without rewriting it: after a heading (under_heading), or at the top/bottom (position). Frontmatter is preserved. Optionally git-commit.
patch_frontmatterUpdate YAML frontmatter keys on a note (e.g. bump updated/status), leaving the body intact. Creates a frontmatter block if absent. Optionally git-commit.
delete_noteDelete a note; optionally git-commit the deletion.
rename_noteRename/move a note AND update every [[wikilink]] to it across the vault (alias/heading/block/embed preserved). Requires flat-unique note names: refuses if the old name is ambiguous or the new name already exists. Path-qualified links ([[dir/Name]]) are not rewritten. Optionally commit.
query_notesFind notes by frontmatter type and/or tag (headless Dataview-lite).
graph_buildbehind configBuild a multi-language code graph from a source tree and store it at .graph/<name>.json. Hidden dirs and common build/vendor dirs are always skipped; `exclude` adds directory names to skip, `include` force-keeps names the rule would skip.

No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
27/27 tools missing one or more hints — list_vaults (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_notes (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); read_note (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +24 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Destructive tools are labelled
1 tool perform destructive updates without destructiveHint — delete_note deletes at line 412 (target.unlink())
Add destructiveHint:true to any tool whose handler calls .delete(), .upsert(), .update(), unlink, rm, DELETE, DROP, REPLACE INTO, or any operation that overwrites existing data.
