Capframe – capability tokens for AI agent tool calls
by euan21·May 19, 2026·1 point·2 comments
AI Analysis
●●●BangerBig BrainSolve My ProblemShip It
Macaroon-style tokens for AI agents solve the excessive agency problem better than prompt engineering.
Strengths
- •Deterministic policy evaluator runs in single-digit microseconds with zero LLM involvement.
- •Mints attenuable, revocable capability tokens with signed denial receipts for audit trails.
- •Auto-generates compliance artifacts mapped to OWASP LLM Top 10 and NIST AI RMF.
Weaknesses
- •Security tooling relies heavily on adoption to create a meaningful threat model.
- •Complexity of managing token lifecycles might deter rapid prototyping workflows.

ClawProxy: An HTTP proxy that injects auth tokens into API calls
It replaces real API keys with short proxy tokens (e.g. PROXY:openai) and uses an X-Upstream-Host allowlist to ensure containers can only hit approved endpoints — neat and low-friction. Comes as a tiny Rust CLI with init/secret set/start commands and clear SDK examples, so you can bolt it onto OpenClaw or Docker agents without adopting a full secrets vault.
