Production guardrails

Security by default.

Network access is constrained before a request leaves the server. Every operation is read-only, every response is bounded, and failed tool calls consume no credits.

01 / NETWORKSSRF protection

Private, loopback, link-local, reserved, and cloud metadata addresses are rejected.

02 / TRANSPORTStrict TLS

Certificate and hostname verification stay enabled. Only ports 80 and 443 are allowed.

03 / CONTROLNo redirects

Redirects are never followed, URL credentials are rejected, and DNS records are validated.

04 / BOUNDSFinite by design

Requests, fetches, text, link sets, batches, and execution time all have hard limits.

Connect
