Loading ToolBench
MCP server for Flutter development tools integration, providing tools for project management, device control, build operations, debugging, and git operations
49 tools with basic verb-noun naming (get_, list_, run_, etc.) and short descriptions (10-50 chars). All tools have input schemas with typed parameters. However, descriptions are uniformly terse and lack LLM-optimized context (WHEN to use, prerequisites, dependencies). Parameter descriptions are minimal or absent. No output schemas documented. Error handling is generic ('error' category with no recovery guidance). No tool annotations (readOnlyHint, destructiveHint). Composition is reasonable (single responsibility per tool), but many tools lack the depth needed for confident LLM selection.
Add a new terminal tab
Clean the project and run pub get
Clear all application logs
Get application logs with optional filtering
Get Flutter and Dart SDK information
Get current workspace status including project path, devices, and capability flags
Get the current state of the integrated terminal
Descriptions uniformly terse (10-50 chars). Lack LLM-optimized context: WHEN to use, prerequisites, dependencies, and how to distinguish from similar tools. E.g., 'Run the Flutter app on the selected device' does not explain when to call run vs hot_reload vs hot_restart.
No output schemas documented. LLMs cannot infer what fields to expect from responses (e.g., get_logs returns what structure? list_devices returns what fields?). Breaks downstream tool chaining.
No tool annotations (readOnlyHint, destructiveHint, idempotentHint). LLMs cannot distinguish safe reads from destructive writes. git_discard and git_delete_branch are marked DESTRUCTIVE but lack annotation hints to guide agent caution.

Generic error handling. McpToolResult.error() returns bare error strings with no recovery guidance. E.g., 'Failed' or 'ArgumentError: Missing path' tells LLM nothing about what to do next (retry? lookup? ask user?).
Tool 'clean_and_pub_get' violates single-responsibility principle. Combines two distinct operations (clean + pub_get). Should split into separate tools so agent can compose as needed.
