    }
  }
}

Run this in your terminal

claude mcp add agentvault --env AGENTVAULT_API_URL=your-value --env AGENTVAULT_AGENT_KEY=your-value -- npx -y agentvault-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

        "AGENTVAULT_AGENT_KEY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "agentvault": {
      "type": "stdio",

Common questions

Is Agentvault safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: AGENTVAULT_API_URL, AGENTVAULT_AGENT_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 6 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

AgentVault

AI-native credential management for autonomous agents. Store API keys with column-level Fernet encryption, issue unique avk_ keys to registered agent identities, proxy decrypted values with TTL, enforce per-agent spending budgets, log every access, and expose everything as an MCP server.

Live API: https://agentvault-api-production.up.railway.app
Docs: https://agentvault-api-production.up.railway.app/docs
Status: Production (Railway + Postgres + Stripe live)

Why

Autonomous agents need API keys to do anything useful — Stripe, OpenAI, SendGrid, your own internal services. Three bad options today:

Hardcode in the agent prompt or config. Leaks in logs, can't rotate, no audit trail.
Pass via env vars at spawn. No per-agent isolation, no budget controls, no revocation without redeploy.
Roll your own vault. Real work — encryption at rest *and* in transit, audit logs, key rotation, budget tracking.

AgentVault is option 3 as a service. One avk_ key per agent. Permission patterns (["stripe_*", "openai_*"]). Daily/monthly spending caps. Full access log. MCP-native so agents can vault.get_credential("stripe_key") and get a TTL-bound decrypted value back.

Quickstart

Direct HTTP

import httpx

resp = httpx.post( "https://agentvault-api-production.up.railway.app/api/v1/vault/get/stripe_key", headers={"X-Agent-Key": "avk_..."}, params={"cost": 0.05}, ) stripe_key = resp.json()["value"]

MCP (Claude Desktop / Cursor / Cline)

"mcpServers": { "agentvault": { "command": "python", "args": ["-m", "mcp_server"], "env": { "AGENTVAULT_API_URL": "https://agentvault-api-production.up.railway.app", "AGENTVAULT_AGENT_KEY": "avk_..." } } } }

Then in Claude: vault.get_credential("stripe_key") returns the decrypted value.

How it works

Column-level Fernet encryption — credentials are encrypted with VAULT_ENCRYPTION_KEY *before* they hit the database. Stronger than at-rest disk encryption alone.
`avk_` agent keys — SHA-256 hashed at rest, never stored plaintext. Recognizable prefix like sk_live_ / whsec_.
Permission patterns — ["stripe_*", "openai_*"] scopes an agent without a full policy engine. fnmatch-based.
Budget enforcement — daily and monthly caps per agent. /vault/get?cost=0.05 records the spend; 429 once the cap is hit.
Audit log — every access (success or denied) goes into credential_access_logs with IP, user-agent, error reason.
MCP server — mcp_server/ exposes list_credentials, get_credential, vault_status, set_budget, view_audit_log as stdio MCP tools.
