# generate_drizzle_schema A write tool on the Mcpg MCP server. Agent View of the PolicyLayer registry record for `generate_drizzle_schema`. HTML page: https://policylayer.com/tools/io-github-devopam-mcpg/generate-drizzle-schema ## Facts - Tool: `generate_drizzle_schema` - Server: Mcpg (`pypi:mcpg`) — https://policylayer.com/tools/io-github-devopam-mcpg.md - Install: `npx -y pypi:mcpg` - Homepage: https://github.com/devopam/MCPg - 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": "generate_drizzle_schema", "arguments": {} } } ``` ## Why generate_drizzle_schema is rated Medium Schema generation is a Write operation—it creates or modifies data structures reversibly. It is not Destructive (no irreversible deletion) and not Execute (no arbitrary code execution). The medium severity reflects that generated schemas could affect database structure, but the reversible nature and typical safeguards in schema generation tools limit blast radius. From the tool's own definition: "Tool name 'generate_drizzle_schema' indicates schema generation; Drizzle is an ORM that generates database schemas." ## Use case AI agents use generate_drizzle_schema to create or update resources in Mcpg, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcpg environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
