Show HN: Agent-fetch – Sandboxed HTTP client with SSRF protection for AI agents

Hacker News - Sat, 02/07/2026 - 11:38pm

Built this because giving AI agents raw HTTP access is scary. agent-fetch is a drop-in HTTP client that blocks SSRF, DNS rebinding, private IP access, and redirect tricks — all at the request level.

It uses its own DNS resolver (Hickory DNS), validates all resolved IPs against a blocklist (loopback, RFC 1918, link-local, cloud metadata, etc.), and pins the TCP connection to the validated IP so there's no TOCTOU gap to exploit.

Also supports domain allowlists/blocklists, rate limiting, body size limits, and timeouts.

Available as a Rust crate and npm package (native Node.js bindings via NAPI).

Built for tool-based agent architectures (MCP, LangChain, etc.) where you control what the agent can call. Not a replacement for container isolation but if your agent only talks to the outside world through HTTP, this locks it down.

Should the blower be placed ant very beging of tube closest to air con . . Half way along the tube .( inbetween the tube and rooms .
