AI agents call scan_repository to retrieve information from MCP Code Analysis Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Scanning a repository performs static analysis and indexing to support semantic code search and domain-driven analysis. It retrieves information about the codebase structure and content but does not create, modify, delete, or execute code.
From the tool's definition The tool is described as 'Scan or rescan a repository' — scanning is an information-gathering operation with no modification of data. The verb 'scan' in the context of code analysis indicates inspection/analysis rather than modification.
Documented attack patterns abuse exactly the kind of access scan_repository gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Code Analysis Server, and nothing reaches the server without passing your rules. This is the rule we recommend for scan_repository:
{
"version": "1",
"default": "deny",
"tools": {
"scan_repository": {}
}
}scan_repository is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Scan or rescan a repository. It is categorised as a Read tool in the MCP Code Analysis Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Code Analysis Server MCP server in PolicyLayer and add a rule for scan_repository: 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 MCP Code Analysis Server. Nothing to install.
scan_repository 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 scan_repository 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 scan_repository. 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.
scan_repository is provided by the MCP Code Analysis Server MCP server (johannhartmann/mcpcodeanalysis). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP Code Analysis Server, 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.
