Agents are ready.
Your governance isn't.

Stipul authorizes mediated agent tool calls before execution, records every decision, and produces tamper-evident evidence afterward.

What is Stipul?

Stipul sits between AI agents and the external tools and APIs they can change. Writ enforces the Charter before execution, Chronicle records every decision, and Seal verifies the resulting evidence. Stipul controls only calls routed through Writ.

One enforcement layer for security, platform, and compliance teams

Security & Operations

Stop dangerous agent tool calls before they execute. Preserve tamper-evident records for incident investigation and response.

Learn more →

Platform & Architecture

Route agent and API actions through one execution boundary instead of scattered SDK checks. Define policy centrally and enforce it at runtime.

Learn more →

Compliance & Legal

Produce provable authorization records for mediated agent actions. Support audit, regulatory, and legal review with cryptographic evidence.
