About

AEVS (Agent Execution Verification System) is a drop-in SDK that records every AI agent tool call and gives agents verifiable execution receipts. It captures the tool, inputs, outputs, status, and timing as tamper-evident proof, so teams can verify what an agent actually executed without relying on chat history or fragile logs.

Launch Llama's Take

Based on Launch Llama data as of November 2026

AEVS has 136 upvotes, including the votes it received on Product Hunt, which ranks it #422 of 2,034 Artificial Intelligence tools on Launch Llama by upvotes, in the top quarter.

Control visibility of receipts with three privacy levels
Integrate with LangChain and MCP frameworks with minimal code changes

Use Cases

Audit teams verifying agent tool execution without replaying agents or relying on chat logs
Demos and shared audits where reviewers need full visibility into tool payloads

Who it is for

AI engineering teams building agents with LangChain or MCP who need execution audit trails.
Compliance or audit reviewers who must independently verify agent tool calls.
Teams in regulated domains like payments, healthcare, or PCI scope who cannot persist raw tool payloads.
