WHAT IT DOES

What http_request does on Mcp Hands

AI agents use http_request to create or update resources in Mcp Hands, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Hands environment.

RISK

Why http_request is rated Medium

An AI agent can call http_request faster than any human can review: one bad instruction and it creates or modifies resources in Mcp Hands by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs http_request safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Hands, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For http_request, this is the rule to start with:

http_request Rate-limited

http_request stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Hands, apply this rule, and every http_request call is checked against it from then on.

What risk level is http_request? +

http_request is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit http_request? +

Yes. Add a rate_limit block to the http_request 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 http_request completely? +
