post_metrics · Topgg MCP: Risk & Policy

WHAT IT DOES

What post_metrics does on Topgg

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

WHY IT NEEDS A POLICY

Why post_metrics needs a policy

This tool submits metrics data to Top.gg, which creates or modifies records on the platform. It is reversible (metrics can be updated or corrected in subsequent calls) and does not delete data or execute arbitrary code. While it could be misused to submit false metrics, the blast radius is limited to the project's own metrics on Top.gg, making it Write rather than Execute. It does not involve financial transactions.

From the tool's definition Tool description states 'Submit a metrics payload' which indicates creating or modifying data on the Top.gg platform.

Verdict

post_metrics Rate-limited

post_metrics 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.

What does the post_metrics tool do? +

Submit a metrics payload for the current Top.gg project. Provide the fields relevant to your project type. It is categorised as a Write tool in the Topgg MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on post_metrics? +

Register the Topgg MCP server in PolicyLayer and add a rule for post_metrics: 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 Topgg. Nothing to install.

What risk level is post_metrics? +

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

Can I rate-limit post_metrics? +

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

Set action: deny in the PolicyLayer policy for post_metrics. 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 post_metrics? +

post_metrics is provided by the Topgg MCP server (paillat-dev/topgg-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
