Connects AI assistants to Obsidian vaults via the Local REST API to search notes, retrieve content, and perform semantic searches. It features self-healing multi-URL connectivity and supports both stdio and HTTP transports for flexible deployment.
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.

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
3/3 tools missing one or more hints — get_note_content (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); obsidian_search (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); obsidian_semantic_search (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint). 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 handlers catch errors
Only 0/3 tool handlers wrap calls in try/catch (0%)
Wrap each tool handler body in try/catch and return a structured error response.
Shell command execution
6 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
No arbitrary install scripts
Has postinstall/preinstall script — runs arbitrary code on npm install
Remove postinstall/preinstall hooks unless they’re essential.
Production dependencies are patched
0 critical, 14 high severity in production deps — @modelcontextprotocol/sdk@1.25.2 (high), axios@1.13.2 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Dependency freshness
3/12 production deps abandoned (no release in 2+ years): find-config@2022-06-18 (4y), axios-debug-log@2022-11-15 (3.6y), json5@2023-03-04 (3.3y)

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.
