find_messages
AI agents call find_messages to retrieve information from Evolution API MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name suggests querying or searching existing messages without creating, modifying, or deleting data. No side effects are apparent from the name or the broader server's message-handling patterns (send_* and get_* tools indicate read/write separation). Despite the empty description reducing confidence slightly, the semantic meaning of 'find_messages' aligns with retrieval operations.
From the tool's definition Tool name 'find_messages' indicates search/query operation over messages. Context from sibling tools (get_chat_messages, list_chats) shows this server provides message retrieval capabilities without modification.

Register the Evolution API MCP Server MCP server in PolicyLayer and add a rule for find_messages: 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 Evolution API MCP Server. Nothing to install.
find_messages 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 find_messages 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 find_messages. 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.
