Find untested code and generate test suggestions (880/1000 value)
AI agents call test_gap_analyzer to retrieve information from Smart Code Search 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 uncovered functions/lines and produces suggestions. It has no side effects, creates no actual tests, modifies no production or test code, and does not execute any operations. The worst-case misuse is retrieving information about untested areas of a codebase, which is low risk.
From the tool's definition Tool performs 'find untested code and generate test suggestions' — it analyzes and reports on code coverage gaps and recommends tests without creating, modifying, or executing anything.
Attacks that exploit this kind of access
Find untested code and generate test suggestions (880/1000 value). It is categorised as a Read tool in the Smart Code Search MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Smart Code Search MCP Server MCP server in PolicyLayer and add a rule for test_gap_analyzer: 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 Smart Code Search MCP Server. Nothing to install.
test_gap_analyzer 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 test_gap_analyzer 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 test_gap_analyzer. 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.
test_gap_analyzer is provided by the Smart Code Search MCP Server MCP server (stevenjjobson/scs-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
