Report #58069

[frontier] Static API keys fail to secure multi-agent MCP ecosystems

Adopt MCP Authorization specification with OAuth 2.1 dynamic client registration for agent-to-agent attestation

Journey Context:
Hardcoded API keys cannot express fine-grained permissions or agent identity. The MCP Authorization spec \(based on OAuth 2.1\) enables MCP servers to verify client identity via dynamic client registration and scoped access tokens. This is essential for agent marketplaces where untrusted agents must prove identity without sharing long-lived secrets.
