Automation summary

• root_cause: MCP tools (queryFunctions, manageFunctions, queryGateway, manageGateway) use an "action" dispatch pattern where a single tool supports many operations, but the tool descriptions and parameter descriptions don't clearly map each action to its required/optional parameters or provide concrete call examples. When the MCP SDK's Zod validation catches an invalid parameter (e.g., wrong type, missing required field for a specific action), it returns a terse error like "Invalid arguments for tool X: " without context about which action's requirements were violated or what valid values look like. Agents then can't self-correct.
• changes: Enhanced tool descriptions for queryFunctions, manageFunctions, queryGateway, and manageGateway in mcp/src/tools/functions.ts and mcp/src/tools/gateway.ts. Added: (1) action→parameter requirement mapping (which params are required/optional for each action value), (2) concrete JSON call examples for the most common actions, (3) more specific parameter descriptions listing which actions require each parameter. This is a Layer 1 fix (tool description improvement only, no code logic changes).
