AI agents call coding_agent_get_diff to retrieve information from LocalAnt without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays git diff information without modifying files, repositories, or any other state. It is a pure query operation with no side effects. The deprecation status does not change its classification. Severity is low because diffs are already-computed outputs with no blast radius from misuse.
From the tool's definition Tool name 'coding_agent_get_diff' and description 'Get the git diff produced by a task' indicate retrieval of diff output. The verb 'Get' and lack of any modification language confirm read-only operation.
Attacks that exploit this kind of access
${DEPRECATED} Get the git diff produced by a task. It is categorised as a Read tool in the LocalAnt MCP Server, which means it retrieves data without modifying state.
Register the LocalAnt MCP server in PolicyLayer and add a rule for coding_agent_get_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 LocalAnt. Nothing to install.
coding_agent_get_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 coding_agent_get_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 coding_agent_get_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.
coding_agent_get_diff is provided by the LocalAnt MCP server (yuga-hashimoto/localant). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
