Veto review
A focused governance layer for approving, denying, and recording AI agent tool calls.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Veto is runtime authorization software for AI agents, designed for teams that need control over actions involving payments, customer data, records, deployments, and other consequential operations. It evaluates tool calls before execution and returns an allow, review, or deny decision based on declarative policies. Human-in-the-loop workflows, decision records, analytics, policy versioning, and an MCP gateway extend its scope beyond a simple approval link.
Pricing follows a freemium model. The Developer plan costs $0 per month and includes the SDK, CLI, email approval links, and a local Apache-2.0 engine, with no credit card required. Hosted costs $299 per month and adds CSV and JSON decision-record export, plus unlimited seats, reviewers, and approval clicks. Enterprise supports cloud, BYOC, on-prem, and isolated-network deployments, along with custom retention, audit export, SSO, and SCIM. Teams should choose Developer for local evaluation and implementation, Hosted for managed team workflows, and Enterprise when deployment or identity requirements demand those controls.
Veto fits teams building governed agent systems across OpenAI, Anthropic Claude, Google Gemini, Amazon Bedrock, Cohere, Groq, Mistral AI, and Together AI, with framework support for Vercel AI SDK, LangChain, LangGraph, CrewAI, AutoGen, MCP, and Playwright. Session-aware call-count and cumulative-value constraints add control over repeated or high-value actions. Its focus is narrower than a conventional deal desk: organizations seeking sales operations, pricing guidance, or standard deal approval management should choose a dedicated deal desk platform instead. Veto is the stronger fit when the central requirement is runtime authorization and an auditable record of AI decisions.
Veto pros and cons
- Where it wins
- Pre-execution policies can allow, deny, or require human review.
- Decision records capture actors, policies, verdicts, and approvers.
- Open-source SDK, MCP gateway, and self-hosted deployment options.
- Where it doesn't
- It targets AI agent governance rather than conventional deal desk operations.
- Enterprise capabilities are available only through the Enterprise plan.
- Teams need to define declarative YAML policies and approval rules.
