AI agents use wopee_send_chat_message to create or modify resources in Wopee. 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 wopee_send_chat_message 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 Wopee.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Send a message to the current project's chat room. Use this to post status updates (e.g., 'Test run started...', 'Analysis complete') or informational messages to the chat. The message will appear as a SYSTEM message in the chat room. Requires WOPEE_PROJECT_UUID to be configured.. It is categorised as a Write tool in the Wopee MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Wopee MCP server in PolicyLayer and add a rule for wopee_send_chat_message: 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 Wopee. Nothing to install.
wopee_send_chat_message 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 wopee_send_chat_message 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 wopee_send_chat_message. 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.
wopee_send_chat_message is provided by the Wopee MCP server (wopee-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
