authorize · Reddirect MCP: Risk & Policy

WHAT IT DOES

What authorize does on Reddirect

AI agents invoke authorize to trigger actions in Reddirect. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why authorize needs a policy

This tool executes an external operation (opening a browser and initiating an OAuth flow) that depends on user interaction and connects an account. It is not purely a read or write operation; it triggers a real-world browser action and authentication process, making Execute the most appropriate category. Severity is medium because misuse could link an unintended account to the session.

From the tool's definition 'opens Reddit in your browser to connect your account' — triggers an external browser action and OAuth authorization flow

Verdict

authorize Rate-limited

authorize stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about authorize

What does the authorize tool do? +

One-time authorization: opens Reddit in your browser to connect your account. You click. It is categorised as a Execute tool in the Reddirect MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on authorize? +

Register the Reddirect MCP server in PolicyLayer and add a rule for authorize: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Reddirect. Nothing to install.

What risk level is authorize? +

authorize is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit authorize? +

Yes. Add a rate_limit block to the authorize rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block authorize completely? +

Set action: deny in the PolicyLayer policy for authorize. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides authorize? +

authorize is provided by the Reddirect MCP server (jeebus87/reddirect). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
