Programmatic tool execution for Vercel AI SDK with MCP integration and efficiency optimizations. Enables orchestrated execution of multiple tools via JavaScript code execution in a sandbox environment.
This server has critical gaps in definition quality. The 'execute' tool is a severe anti-pattern that enables arbitrary code execution without proper safeguards, documentation of output schemas, or error handling guidance. The Azure management tools (listSubscriptions, listResourceGroups, listResources, listPolicies) have basic descriptions but lack critical details: no parameter enums for constrained inputs, no documented output schemas, no pagination guidance, no error recovery hints. Parameter descriptions are minimal (10-30 chars typically), violating the 10-1024 char guideline and the requirement that every param have a substantive description. The 'execute' tool's description (240 chars) is too vague about security implications, output structure, and when NOT to use it. Tools lack composition guidance, no hint that execute is meant to orchestrate multiple calls efficiently. No tools declare their risk level, permissions required, or audit trail expectations. listResources accepts 6 parameters but provides no guidance on mutual exclusivity, valid formats, or result limits.
Execute JavaScript code to orchestrate multiple tool calls efficiently. USE THIS TOOL when you need to process multiple items or make 3+ tool calls. Supports both local tools and MCP tools. Includes defensive helper functions: toArray, safeGet, safeMap, safeFilter, first, len, isSuccess, extractData, extractText, getCommandOutput.
List policies (truncated in source, but tool exists)
List resource groups in a subscription
List resources in a subscription or resource group
List all Azure subscriptions available to the current user
execute tool is a code injection vector without input validation, sandboxing declaration, or output schema documentation. No mention of security constraints or what outputs the helper functions produce.
Parameter descriptions are too brief or missing. 'includeDetails' has 37 chars, 'subscriptionId' has 21 chars, 'filter' has 47 chars.
No output schemas documented. Azure list operations can return thousands of items, no mention of pagination (limit, offset, next_cursor), result caps, or field structure. listResources accepts 'top' param but no guarantee it works or what total count looks like.

listPolicies has empty description and no visible input schema. Cannot determine what this tool does, what parameters it accepts, or what it returns.
Parameter enums missing. 'resourceType' in listResources accepts free-form strings like 'Microsoft.Compute/virtualMachines', should provide enum or pattern validation. No guidance on OData filter syntax for 'filter' params.
No error handling guidance. What happens when subscriptionId is invalid? User not authenticated? Quota exceeded? No recovery hints for LLM (e.g., 'try calling listSubscriptions first').
No tool composition hints. execute tool is positioned as an orchestrator but no guidance on when to prefer it vs. direct tool calls, how to structure code, what helper functions return, or error handling within the sandbox.
listResources parameter relationships undocumented. 'filter', 'expand', 'top', and 'resourceType' likely have dependencies or mutual exclusivity, no guidance on which combinations are valid or efficient.
