What rate-limited does on Frontmcp
AI agents call rate-limited to retrieve information from Frontmcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why rate-limited is rated Low
An echo tool retrieves and returns data provided to it with no side effects. This is a read operation. The rate limiting indicates low risk of abuse. Severity is low because even if misused, echoing data back causes no harm to systems or data integrity.
From the tool's definition The tool is described as 'A rate-limited echo tool' — echo tools simply return input data without modification, deletion, or side effects. Rate limiting is a safety wrapper, not a functional descriptor.
Attacks that exploit this kind of access
The rule that runs rate-limited safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Frontmcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For rate-limited, this is the rule to start with:
rate-limited is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Frontmcp, apply this rule, and every rate-limited call is checked against it from then on.
Questions about rate-limited
A rate-limited echo tool (3 requests per 5 seconds). It is categorised as a Read tool in the Frontmcp MCP Server, which means it retrieves data without modifying state.
Register the Front MCP server in PolicyLayer and add a rule for rate-limited: 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 Frontmcp. Nothing to install.
rate-limited is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the rate-limited 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.
Set action: deny in the PolicyLayer policy for rate-limited. 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.
rate-limited is provided by the Front MCP server (agentfront/frontmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
