Recommended for stdio), ONECLAW_AGENT_ID (Optional agent UUID when pinning identity (usually auto-discovered from the API key)), ONECLAW_VAULT_ID (Optional vault UUID when the agent can access multiple vaults), ONECLAW_BASE_URL (Vault API base URL (default https://api.1claw.xyz)), ONECLAW_LOCAL_ONLY (Set to true for security-only mode (inspect_content only; no vault credentials)).

1Claw Vault — questions

Answers built from our own checks of this server.

Why is there no uptime for 1Claw Vault?
1Claw 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 @1claw/mcp was installed 1 253 times last week.
How do I connect 1Claw Vault?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls @1claw/mcp straight from npm; nothing to host, nothing to sign up for.
How many people use 1Claw Vault?
The npm package @1claw/mcp was installed 1 253 times in the last week. Week over week that is +125%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is 1Claw Vault open source?
Yes — it is published under the MIT licence, written in TypeScript, 4 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
