Cyphrex

R1· needs a key

Blockchain SSN for AI agents. MCP gateway that blocks at the point of action, tamper evident audit.

v0.2.1 · active · repository · descriptor JSON · versions

An agent can connect on its own if it already holds CYPHREX_MCP_TOKEN.Remote endpoint behind a static API key or header. The registry never sees the value; the agent fills the placeholder.

Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.
