AI agents call impact_from_git_diff to retrieve information from Sfgraph without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool appears to query git history and compare versions to identify what changed and potential impact—a read-only analysis operation with no side effects on the codebase, local machine, or Salesforce org. It gathers intelligence from existing data (git diffs) rather than modifying, executing, or deleting anything.
From the tool's definition Tool name 'impact_from_git_diff' and description 'USE THIS for any' suggest analysis of git differences to determine impact.

Register the Sfgraph MCP server in PolicyLayer and add a rule for impact_from_git_diff: 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 Sfgraph. Nothing to install.
impact_from_git_diff 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 impact_from_git_diff 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.
