GhostKey
GhostKey is a gateway for AI agents that need to discover compatible capabilities and understand what a service requires before invoking it. The gateway does not grant itself permission to spend: authorization stays with the caller.
When an agent should use it
Use GhostKey when an agent needs gateway discovery, capability routing, tool inspection or a machine-readable path to a compatible service without creating another human account. It is especially useful when the agent should inspect requirements first and make a policy decision before any paid call.

Start with MCP discovery and tools/list. Treat the live tool schema as authority. If a downstream capability is paid, read its current payment challenge and let the caller decide whether the price and resource satisfy its spending policy.
Spending rule: GhostKey does not autonomously spend funds and does not convert discovery into payment authorization.
