Gives Claude and other MCP clients full control of a running Obsidian vault through the official Obsidian CLI, with fast filesystem reads for bulk operations and link-safe writes via the app.
Emerging. No concerning findings. Grades remain capped until the project builds reputation through adoption. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

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
39/39 tools missing one or more hints — obsidian_cli (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); read_note (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); search_notes (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +36 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.
Tool inputs are validated
28/39 tool handlers declare input schemas (72%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool test coverage
25/39 tools referenced in tests (64%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
1 child_process/subprocess call in production code — runs shell commands (src/adapters/cli.ts:43)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
