Show git diff
AI agents call git_diff to retrieve information from FGD Fusion Stack Pro without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The git diff command retrieves and displays version control information without side effects. It does not create, modify, delete, or execute any operations—it only queries and presents git repository state. This is a standard Read category tool with low severity due to limited blast radius if misused by an AI agent.
From the tool's definition Tool name 'git_diff' and description 'Show git diff' indicates retrieval of git diff output. Git diff is a read-only operation that displays differences between commits, branches, or working directory without modifying any data.
Attacks that exploit this kind of access
Show git diff. It is categorised as a Read tool in the FGD Fusion Stack Pro MCP Server, which means it retrieves data without modifying state.
Register the FGD Fusion Stack Pro MCP server in PolicyLayer and add a rule for 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 FGD Fusion Stack Pro. Nothing to install.
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 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.
Set action: deny in the PolicyLayer policy for git_diff. 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.
git_diff is provided by the FGD Fusion Stack Pro MCP server (mikeychann-hash/mcpm). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
