> **93 agentic tools. 49 specialists. Every major AI CLI. Self-learning. Zero extra cost on subscriptions.**
An MCP server that runs locally on your machine, plugs into Claude Code, Codex CLI, Gemini CLI, Antigravity CLI, Cursor, Windsurf, Zed, and JetBrains using your existing subscriptions — giving every AI a council of specialist agents, local LLM support, SDD agents, playwright automation, persistent cross-platform memory, a self-learning router that re-tunes its tier thresholds automatically every 20 recorded task outcomes (reviews record outcomes for you; configurable via auto_apply_learning), CI/CD gates, workspace discovery, and bidirectional IDE communication.
> **Billing note:** "Zero cost" applies to subscription plans (Claude Max, Gemini Advanced, etc.). If you are on API/pay-per-token billing, LLM reasoning done for Veto agents (via the agentic loop or MCP Sampling) counts toward your token usage like any other turn. veto init detects API key environment variables and warns you automatically.

Getting Started
Prefer not to install anything? Every command also works via npx:
The two are independent by design. veto init writes MCP configs that launch the server with npx -y --package @jigyasudham/veto@latest veto-server — npx re-resolves @latest against the registry on every client restart, so the **MCP server auto-updates itself** and a global copy can never pin it to an old version. The **global install only provides the CLI** (veto doctor, veto sessions, the statusline, …); keep it current with npm i -g @jigyasudham/veto@latest when veto doctor says it's behind.

How the Agents Work
**No API keys, zero extra cost.** Every worker agent is a deterministic expert module at its core, with two optional layers of LLM reasoning on top — all of it delegated to the AI you're already paying for.
Default — Deterministic expert modules
Out of the box, each of the 42 worker agents runs as a hand-written expert module (plan() / analyze() in src/agents/) — **not** an LLM. They always run, work offline, and cost zero tokens. Their depth varies by design: analysis agents (security scanner, secrets, dependency audit, clone detector, privacy, auth, performance, compatibility, …) apply real algorithms — regex/AST detection, OWASP/CWE rules, hash-based clone matching — while planning agents (coder, debugger, tester, …) are structured expert playbooks: curated steps, checklists, and pitfalls for the task category, built to be reasoned over by the AI you already pay for rather than to reason themselves.
Path A — Agentic loop (most clients: Claude Code, Cursor, Windsurf)
Veto returns the specialist's role, rubric, and an output contract as an llm_upgrade prompt. The host AI reasons as the specialist and passes structured JSON back to complete the operation. This is the primary path — it costs nothing beyond your existing subscription and works on every client.
Path B — MCP Sampling (clients that support server.createMessage)
Where Sampling is available, the same upgrade happens server-side without the extra round-trip. Note: the July 2026 MCP spec revision deprecates Sampling protocol-wide (12-month sunset), so the agentic loop (Path A) is Veto's long-term default; Sampling remains a transparent optimization where it exists.
The 7-agent **Council** is LLM-first — its value is the multi-agent debate — but it too falls back to a deterministic verdict when no LLM path is available. When multiple agents run, they execute in parallel.

Specialist Roles
**49 specialists: 42 deterministic worker agents across 6 domains + a 7-agent Council.** The Council debates trade-offs before you build; the worker agents do the hands-on analysis and planning. Each is a deterministic expert module that can upgrade to LLM reasoning — see How the Agents Work. List them anytime with veto agents.
