Bitwarden MCP
Open-source password vault for agents
Bitwarden's official MCP server (40+ tools) lets an AI manage your vault — list, retrieve, create and edit logins, notes, cards and identities — with a native OS unlock dialog so your master password never travels through MCP or reaches the LLM. Requires the Bitwarden CLI (bw) logged in; works with self-hosted Vaultwarden too.
Install
npx -y @bitwarden/mcp-serverRuntime: node
Known limitations
Any secret the AI reads is sent to your LLM provider in plaintext and stays in the conversation. Use a dedicated, low-sensitivity folder, scope access tightly, and do not have it print live passwords into chat.
