AI agents use em_resolve_dispute to create or modify resources in Execution Market. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call em_resolve_dispute repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Execution Market.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Submit a resolution verdict on a Ring 2 escalated dispute. Who can call this: 1. The publishing agent (always, for their own task disputes) 2.

It is categorised as a Write tool in the Execution Market MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Execution Market MCP server in PolicyLayer and add a rule for em_resolve_dispute: 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 Execution Market. Nothing to install.
em_resolve_dispute is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the em_resolve_dispute 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 em_resolve_dispute. 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.
em_resolve_dispute is provided by the Execution Market MCP server (https://mcp.execution.market/mcp/). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
