While reversible (modified files can be undone via version control), it is a Write operation that persistently changes application code. It is not Destructive because modifications are not irreversible deletions. It is not Execute because it does not run code—it writes code definitions. From the tool's own definition: "Tool description states it 'Adds a new tool definition to an existing MCP server project by reading the src/index.ts file and appending the tool registration.' The verb 'Adds' and 'appending' indicate creation/modification of code files." ## Use case AI agents use sf_create_mcp_tool to create or update resources in Salesforce Metadata Mcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Salesforce Metadata Mcp environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
