Questions
What is the Markdown Vault MCP server?
Generic markdown vault MCP with hybrid search
What tools does Markdown Vault expose?
2 in total: 2 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is Markdown Vault safe to connect to an agent?
No — not without reading the findings first. The audit graded it F (39/100) and found 1 critical or high issue in the source. Each one is listed on this page with the file and line it is on.
What credentials does Markdown Vault need?
It reads GITHUB_TOKEN, MARKDOWN_VAULT_MCP_BEARER_TOKEN, MARKDOWN_VAULT_MCP_OIDC_CLIENT_SECRET, MARKDOWN_VAULT_MCP_OIDC_JWT_SIGNING_KEY, OPENAI_API_KEY and VOYAGE_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How does Markdown Vault run?
It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on PyPI as markdown-vault-mcp.
How current is this page?
The grade is for one exact copy of the source (0c61c82af626), read on 2026-10-09. The repository is watched and re-audited when it changes.
