SolonGate is the guardrail for AI agents. It checks every action an agent takes (each shell command, file read or write, and network request) and allows, blocks, or logs it before it runs, based on a policy you control. No code changes.

Get started

You need a free SolonGate account and Node.js 20+ on the machine you want to protect. There's nothing to import; the two commands below pair your machine.

npm i -g @solongate/proxy
solongate

solongate opens your browser to authorize the device. Approve it and SolonGate installs a global guard hook that checks every tool call from every AI session on the machine against your active policy. No API keys to copy.

Start a new terminal session afterwards. Hooks load when a
session starts, so already-open terminals aren't guarded yet.

Guarding a live Claude Code session

Drops in front of any MCP-speaking agent over stdio, SSE, or HTTP. Every tool call is checked in real time, and each allow or deny decision streams to your dashboard with the full arguments attached.

Command center for every decision area

Live analytics by tool, agent, and policy. Version your policies with cloud sync and one-click rollback. Every decision lands in a tamper-evident, searchable audit trail you can export as CSV.

What SolonGate can enforce

• Policy rules: allow or block tool calls by path, command, filename, or URL.
• Ghost paths: make chosen files and folders invisible to the agent, unlistable and unreadable.
• Data loss prevention (DLP): when a call carries a secret (API key, token, private key), block it or hide it from the model.
• Rate limiting: cap how many tool calls an agent can make per minute, hour, or day.

Manage everything from the Policies, Audit, and Settings pages in the dashboard. When a legitimate action is blocked, click Whitelist this to add a narrow exception. Keep logs local instead of in the cloud, and get alerted by Telegram, email, or webhook when blocks spike.

Compatible with every tool. SolonGate guards any MCP-speaking agent out of the box. Missing yours? Reach out and we will consider it.
