average firewall check latency

Three checks. One firewall.

Composable, agent-callable services that verify and improve LLM outputs before they cause damage.

Package Validator

19.7% of AI-generated imports don't exist. We check every one against PyPI, npm, crates.io, and Go — in under 200ms.

POST /v1/validate/imports

Hallucination Firewall

Returns PASS, FLAG, or BLOCK for any LLM output. Catches bad packages, dead URLs, malformed citations, and numeric contradictions. Every verdict is SHA-256 certified.

POST /v1/verify

Context Distiller

Trim bloated agent context windows to a token budget. Keep the system prompt, deduplicate, and slice from newest to oldest. Up to 80% compression.

POST /v1/distill

Catch it before it runs

Send AI-generated code. Get a verdict in milliseconds.

Model Context Protocol

Works with Claude, Warp, Cursor — any MCP client

Drop agent-toolbox into your MCP config and your agent gets three quality tools out of the box. No SDK, no glue code.
