AI agents call analyze_code to retrieve information from Code Merge MCP 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 content to generate analytical insights and statistics. It has no side effects—it does not modify, delete, execute, or move data. It is a read-only operation that fits the 'Read' category for data retrieval tools.
From the tool's definition Tool name is 'analyze_code' and description states it 'Analyzes code files and provides statistics.' The verb 'analyzes' and 'provides statistics' indicate data retrieval and inspection without modification or execution of code.
Documented attack patterns abuse exactly the kind of access analyze_code gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Code Merge MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for analyze_code:
{
"version": "1",
"default": "deny",
"tools": {
"analyze_code": {}
}
}analyze_code is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Analyzes code files and provides statistics. It is categorised as a Read tool in the Code Merge MCP MCP Server, which means it retrieves data without modifying state.
Register the Code Merge MCP server in PolicyLayer and add a rule for analyze_code: 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 Merge MCP. Nothing to install.
analyze_code 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 analyze_code 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 analyze_code. 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.
analyze_code is provided by the Code Merge MCP server (yy1588133/code-merge-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Code Merge MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
