Install the agent guardrail before the next repeated mistake costs real money.

ThumbGate is live on the surfaces developers already use: npm, VS Code Marketplace, Open VSX, GitHub Release assets, and MCP Registry. If the risky workflow is already customer-visible, start with the Setup Sprint instead of another generic install.

Choose the install path that matches your agent.

Use the local CLI path for immediate enforcement. Use marketplace installs where your editor supports them. Use the diagnostic path when you need a human-reviewed gate map for one risky workflow. New install: prove the pipe first (doctor green, empty dashboard OK) before expecting a gate to fire.

First gate block in one command

Promote your first prevention rule, watch ThumbGate block a repeat mistake live, and unlock the built-in safety rule pack + 3 custom block rules on the Free tier (7-day local Pro trial included).

npx thumbgate quickstart

CLI and MCP-compatible agents

Fastest path for Claude Code, Cursor, Codex, Gemini CLI, Amp, Cline, OpenCode, and local MCP-compatible agents.

npx -y thumbgate@1.40.1 init --agent claude
npx -y thumbgate@1.40.1 doctor
npx -y thumbgate@1.40.1 doctor --fix

Claude Desktop

Use the npm-backed MCP server today. The Claude Desktop `.mcpb` directory submission packet is prepared separately.

claude mcp add thumbgate -- npx --yes --package thumbgate@1.40.1 thumbgate serve

Cursor

The public Cursor Marketplace listing is not live yet. Use the CLI wiring while the dashboard submission is resolved.

npx -y thumbgate@1.40.1 init --agent cursor

Codex

Use the local adapter now. Public Codex self-serve plugin publishing is not open yet, so the GitHub Release asset is the distribution proof.

npx -y thumbgate@1.40.1 init --agent codex

Grok

Grok Build CLI. There is no Grok store listing. This command adds the npm server. npx thumbgate init also writes the Claude-style config Grok reads.

grok mcp add thumbgate -- npx -y thumbgate mcp

Hermes

Local hook for Nous Research Hermes. Merge adapters/hermes/config.yaml into ~/.hermes/config.yaml. There is no Hermes directory listing.

npx --yes --package thumbgate thumbgate hermes-gate

When install is not enough, buy the diagnostic.

If one AI-agent workflow already touches customers, money, production, outbound messages, browser automation, or deploy approvals, a generic install is not enough. The Setup Sprint turns the repeated failure into one configured local gate, a regression test, and rollout and rollback proof.
