HTML page: https://policylayer.com/tools/aiquila-nextcloud-mcp-server/talk-react-to-message ## Facts - Tool: `talk_react_to_message` - Server: AIquila — Nextcloud MCP Server (`elgorro/aiquila`) — https://policylayer.com/tools/aiquila-nextcloud-mcp-server.md - Homepage: https://github.com/elgorro/aiquila.git - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "talk_react_to_message", "arguments": {} } } ``` ## Why talk_react_to_message is rated Medium This tool creates a new emoji reaction object associated with a message, which is a reversible write operation. It does not execute code, delete data, move money, or retrieve sensitive information. The blast radius is minimal—a reaction can be removed and does not affect core data integrity. Severity is low because the operation is benign, localized to a single conversation, and easily undone. From the tool's own definition: "The tool description states it 'Add[s] an emoji reaction to a message' in a Talk conversation. This is a create operation that modifies conversation state by adding a reaction object." ## Use case AI agents use talk_react_to_message to create or update resources in AIquila — Nextcloud MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your AIquila — Nextcloud MCP Server environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
