Get collected code coverage data.
AI agents call get_coverage to retrieve information from MCPEmulate without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries code coverage information from an emulation session. It performs no modifications, deletions, or external operations—it simply returns data that has been collected. The tool fits the 'Read' category as it fetches information with no side effects.
From the tool's definition Tool name 'get_coverage' and description 'Get collected code coverage data' indicate retrieval of existing coverage metrics without modification or side effects.
Attacks that exploit this kind of access
Get collected code coverage data. It is categorised as a Read tool in the MCPEmulate MCP Server, which means it retrieves data without modifying state.
Register the MCPEmulate MCP server in PolicyLayer and add a rule for get_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 MCPEmulate. Nothing to install.
get_coverage 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 get_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.
Set action: deny in the PolicyLayer policy for get_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.
get_coverage is provided by the MCPEmulate MCP server (labguy94/mcpemulate). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
