AI agents call coderank_analysis to retrieve information from Search Tools MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool analyzes code structure and importance rankings without executing code, deleting data, or modifying repositories. It queries existing code patterns to surface insights. The empty description lowers confidence slightly, but the server's stated purpose (analysis and search) and sibling tools (all analytical in nature) confirm this is a Read operation with minimal blast radius if misused.
From the tool's definition Tool name 'coderank_analysis' and server description indicate this performs code analysis and ranking using the CodeRank algorithm to 'identify critical modules, trace dependencies, find code hotspots.' These are read-only operations that retrieve and analyze…
Documented attack patterns abuse exactly the kind of access coderank_analysis gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Search Tools MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for coderank_analysis:
{
"version": "1",
"default": "deny",
"tools": {
"coderank_analysis": {}
}
}coderank_analysis is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

coderank_analysis. It is categorised as a Read tool in the Search Tools MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Search Tools MCP Server MCP server in PolicyLayer and add a rule for coderank_analysis: 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 Search Tools MCP Server. Nothing to install.
coderank_analysis 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 coderank_analysis 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 coderank_analysis. 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.
coderank_analysis is provided by the Search Tools MCP Server MCP server (voxmenthe/search-tools-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
