Returns process.cwd()
AI agents call getCwd to retrieve information from Mcp Docs Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about the current working directory, which is a read-only operation with no side effects. It has minimal blast radius as it only exposes the directory path of the running process. Classification as 'Read' is appropriate.
From the tool's definition Tool name 'getCwd' and description 'Returns process.cwd()' indicate a read-only operation that retrieves the current working directory without modification.

getCwd 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 getCwd 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.
