Check if another agent is editing a file
AI agents call check_file_conflict to retrieve information from Mcp Coordinator without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves the current state of file editing conflicts—whether another agent is working on a file—but does not modify any state, execute operations, or cause destructive changes. It is a pure query operation that helps agents make decisions without altering system state. Classification as Read is appropriate.
From the tool's definition The tool name is 'check_file_conflict' and the description states it 'Check if another agent is editing a file'. The verb 'check' and the read-only nature of querying conflict status indicates data retrieval with no side effects.
Attacks that exploit this kind of access
Check if another agent is editing a file. It is categorised as a Read tool in the Mcp Coordinator MCP Server, which means it retrieves data without modifying state.
Register the Mcp Coordinator MCP server in PolicyLayer and add a rule for check_file_conflict: 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 Mcp Coordinator. Nothing to install.
check_file_conflict 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 check_file_conflict 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 check_file_conflict. 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.
check_file_conflict is provided by the Mcp Coordinator MCP server (swoofer/mcp-coordinator). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
