# create_schematic_symbol A write tool on the Altium-MCP-Suite MCP server. Agent View of the PolicyLayer registry record for `create_schematic_symbol`. HTML page: https://policylayer.com/tools/altium-mcp-suite/create-schematic-symbol ## Facts - Tool: `create_schematic_symbol` - Server: Altium-MCP-Suite (`M-R-Abedini/Altium-MCP-Suite`) — https://policylayer.com/tools/altium-mcp-suite.md - Homepage: https://github.com/M-R-Abedini/Altium-MCP-Suite - 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_schematic_symbol", "arguments": {} } } ``` ## Why create_schematic_symbol is rated Medium This tool creates a new schematic symbol, which is a reversible modification to the Altium project design. It does not delete data (would be Destructive) or execute arbitrary code (would be Execute). The severity is medium because misuse could require rework but symbols can be deleted or modified to correct errors. From the tool's own definition: "Tool name is 'create_schematic_symbol' which indicates creation of a new resource (schematic symbol) in the Altium project. The description is empty, but the verb 'create' clearly indicates a Write operation that modifies the project." ## Use case AI agents use create_schematic_symbol to create or update resources in Altium-MCP-Suite, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Altium-MCP-Suite environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
