Veto
Veto checks AI-agent tool calls before execution and returns an allow, deny or approval-required verdict.
What Veto is
Veto checks AI-agent tool calls before execution and returns an allow, deny or approval-required verdict. Policies can permit safe actions, pause risky actions for approval and block forbidden ones. Decision records can include the actor, tenant, tool, policy and approver. Listed integrations include OpenAI, Anthropic, Gemini, Amazon Bedrock, Cohere, Groq, Mistral, Together AI, LangChain, LangGraph, MCP and Playwright. TypeScript is the production SDK path, while Python is a preview package for local checks. Veto says its Apache-2.0 SDK and policy engine can run locally, and cached policy can keep critical enforcement operating if its cloud is unreachable. Customer payloads, policies and decision records are processed to provide the service and are not used to train models. The Developer plan is free with 5,000 action checks and seven days of records. Hosted costs $299 a month; Enterprise pricing is custom.
