# ProphetKey — API Key Vault for AI Agents
Offline-first, encrypted API key vault with local MCP bridge for AI agents.
## What is ProphetKey?
ProphetKey is a desktop app that securely stores API keys (OpenAI, Anthropic, GitHub, etc.) and exposes a **local MCP server** (`127.0.0.1:1421/mcp`). AI agents can call 5 tools over stdio or HTTP to read keys, check health, and make API calls — **real keys never reach the agent**.
## Quick start (stdio via npm)
Install and configure in one step — works with Claude Code, Cursor, Windsurf, and any MCP-compatible agent.
```bash
# One-liner to run
npx -y prophetkey-mcp

Scored across 5 tools
Each tool has a clearly distinct purpose: listing keys, retrieving key details, checking proxy status, running health checks, and making proxied requests. There is no meaningful overlap that would cause an agent to select the wrong tool.
All tools follow a consistent `prophetkey_` prefix with snake_case verb_noun names. The pattern is uniform and predictable across the entire set.
Five tools is a well-scoped size for this server's purpose. Each tool covers a distinct aspect of interacting with ProphetKey and its proxy without unnecessary bloat or redundancy.
The set covers the core workflows: discovering keys, inspecting key details, checking health, monitoring the proxy, and making authenticated requests. Lifecycle operations like adding or deleting keys are absent, but they appear intentionally handled outside the MCP server rather than being an obvious gap.
