Return top-level modules/packages/files that changed since base_branch.
AI agents call get_changed_modules to retrieve information from GitHub PR Template Tools without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and reports information about code changes between git branches without modifying, executing, or deleting any data. It is analogous to running 'git diff --name-only' to list changed files. This is a safe, informational operation that would have minimal risk even if an AI agent misused it — at worst, it provides inaccurate change summaries for PR template suggestions.
From the tool's definition Tool description states it 'Return[s] top-level modules/packages/files that changed since base_branch' — a retrieval operation with no side effects. The verb 'Return' and the read-only nature of querying git change metadata confirm this is a query operation.
Attacks that exploit this kind of access
Return top-level modules/packages/files that changed since base_branch. It is categorised as a Read tool in the GitHub PR Template Tools MCP Server, which means it retrieves data without modifying state.
Register the GitHub PR Template Tools MCP server in PolicyLayer and add a rule for get_changed_modules: 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 GitHub PR Template Tools. Nothing to install.
get_changed_modules 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 get_changed_modules 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 get_changed_modules. 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.
get_changed_modules is provided by the GitHub PR Template Tools MCP server (sawantudayan/github-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
