WHAT IT DOES

What coverage does on Git

AI agents invoke coverage to trigger actions in Git. 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.

RISK

Why coverage is rated High

The tool runs tests (code execution) and collects coverage data. This constitutes executing code/commands on the host system. Misuse could trigger unintended side effects from the test suite itself, consume significant resources, or expose sensitive information in test output. It is more than a Read because it actively runs processes, placing it in Execute.

From the tool's definition 'Runs tests with coverage' — the tool actively executes a test suite with coverage instrumentation

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs coverage safely

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

coverage Rate-limited

coverage 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.

  "version": "1",
  "default": "deny",
  "tools": {
    "coverage": {
      "limits": [
        {
          "counter": "coverage_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

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

FAQ

Questions about coverage

What does the coverage tool do? +

Runs tests with coverage and returns structured coverage summary per file. It is categorised as a Execute tool in the Git MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on coverage? +

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

What risk level is coverage? +

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

Can I rate-limit coverage? +

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

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

coverage is provided by the Git MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
