HTML page: https://policylayer.com/tools/app-businys-mcp-server/create-exercise ## Facts - Tool: `create_exercise` - Server: Businys (`@businys/mcp-server`) — https://policylayer.com/tools/app-businys-mcp-server.md - Install: `npx -y @businys/mcp-server` - Homepage: https://github.com/hiatys/businys-mcp - 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": "create_exercise", "arguments": {} } } ``` ## Why create_exercise is rated Medium This tool creates a new exercise record, which is a reversible write operation. There is no code execution, financial transaction, or data deletion involved. The blast radius is minimal—a mistaken exercise creation can be easily corrected or deleted by the user. Low severity because the action is non-destructive and domain-specific to fitness data management. From the tool's own definition: "Tool name 'create_exercise' and description 'Create a custom exercise' explicitly indicate data creation." ## Use case AI agents use create_exercise to create or update resources in Businys, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Businys environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
