A personal knowledge vault MCP server for Claude Desktop — capture thoughts, connect ideas, and reflect on how your thinking is changing, all through natural conversation.

Showcase
A vault is more than a folder of notes — it's a mirror of how you think. vault_reflect turns that mirror into something you can look at.

Why this exists
Most note-taking tools stop at storage. vault-mcp is built around a three-layer vision:
- L1 · Capture — frictionless save from any conversation, with auto-tagging and slug generation.
- L2 · Connect — promote raw captures into structured notes with auto-wikilinks, build a knowledge

Built from this server's own package name, version and transport as found in its source — not copied from anyone's documentation, so it cannot drift against a page we do not control.

Questions
What is the Knowledge Vault MCP server?
An intelligent knowledge management system connecting your local knowledge vault with Claude Desktop via MCP
What tools does Knowledge Vault expose?
7 in total: 5 read-only, 1 that write, and 1 that can delete or overwrite (vault_capture). Every one is listed on this page with its risk.
Is Knowledge Vault safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B. Separately from the audit: 1 of its tools can destroy data, so scope the token you give it to what you actually need.
What credentials does Knowledge Vault need?
No credential environment variables were found in its source, so it appears to need none.
How does Knowledge Vault run?
It speaks stdio, so it runs as a local process your client starts. It is published on PyPI as obsidian-in-a-vat-mcp.
How current is this page?
The grade is for one exact copy of the source (3d1890310f03), read on 2026-10-09. The repository is watched and re-audited when it changes.
