This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start: VAULT_REGION (Bitwarden region or self-hosted mode (e.g. us, eu, or self-hosted).), VAULT_API_BASE (Base URL for self-hosted Vaultwarden, scheme+host only (e.g. https://pass.example.com). Omit for Bitwarden cloud.), VAULT_CLIENT_ID (Bitwarden API client_id (personal API key).), VAULT_CLIENT_SECRET (Bitwarden API client_secret (personal API key).), VAULT_MASTER_PASSWORD (Vault master password, used to unlock and decrypt items.). The author declared them in the registry entry; get the values from the project itself.

MCP Server Vault — questions

Answers built from our own checks of this server.

Why is there no uptime for MCP Server Vault?
MCP Server Vault runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @aiwerk/mcp-server-vault was installed 72 times last week.
How do I connect MCP Server Vault?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls @aiwerk/mcp-server-vault straight from npm; nothing to host, nothing to sign up for.
How many people use MCP Server Vault?
The npm package @aiwerk/mcp-server-vault was installed 72 times in the last week. Week over week that is +40%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is MCP Server Vault open source?
Yes — it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
