Scan the git diff for any potential secrets or tokens.
AI agents call detect_sensitive_tokens 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 reads and analyzes git diff data to detect patterns matching secrets or tokens. It produces informational output (detection results) without modifying code, executing operations, or triggering external side effects. The purpose is to surface security issues for human review, making it a Read operation with low blast radius if misused by an AI agent—worst case, it flags false positives in a diff analysis.
From the tool's definition Tool is described as 'Scan the git diff for any potential secrets or tokens' — a scanning/analysis operation with no side effects. The verb 'scan' and context of analyzing existing git data indicates data retrieval and inspection only.
Attacks that exploit this kind of access
Scan the git diff for any potential secrets or tokens. 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 detect_sensitive_tokens: 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.
detect_sensitive_tokens 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 detect_sensitive_tokens 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 detect_sensitive_tokens. 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.
detect_sensitive_tokens 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.
