Find exported symbols with no test coverage, ranked by blast radius. Useful for prioritizing test writing.
AI agents call coverage_gaps to retrieve information from code-intel MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only analysis tool that queries code metadata to identify gaps in test coverage. It does not execute code, modify code, delete anything, or move money. It merely retrieves and analyzes existing information about test coverage status, making it a Read category tool. The low severity reflects that misuse would only provide misleading analysis rather than cause actual system harm.
From the tool's definition The tool 'coverage_gaps' finds and returns information about exported symbols lacking test coverage, ranked by blast radius.
Attacks that exploit this kind of access
Find exported symbols with no test coverage, ranked by blast radius. Useful for prioritizing test writing. It is categorised as a Read tool in the code-intel MCP Server MCP Server, which means it retrieves data without modifying state.
Register the code-intel MCP Server MCP server in PolicyLayer and add a rule for coverage_gaps: 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 code-intel MCP Server. Nothing to install.
coverage_gaps 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 coverage_gaps 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 coverage_gaps. 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.
coverage_gaps is provided by the code-intel MCP Server MCP server (vohongtho/code-intel-platform). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
