This server exposes 4 tools for block testing within a Tauri desktop app. However, critical inspection of the source code reveals severe definition quality gaps. The tools are defined in src/renderer/components/tools/block-tester/panels/DevTools.tsx, a React component file, which is highly atypical for MCP server tool registration. No explicit MCP tool registration code is visible in the provided source. Tool definitions appear to be inferred from component state and props rather than formally registered with the MCP SDK. All tools have minimal descriptions (under 100 chars), and several lack proper parameter documentation. Input schemas are present for some tools but incomplete. No output schemas are documented. Error handling guidance is absent. The server appears to be a Tauri desktop application with MCP integration layered on top, not a proper MCP server implementation.

• Verify that tools are registered explicitly via @modelcontextprotocol/sdk ServerManager or equivalent. If they are only inferred from React component state, formally register them with proper MCP tool definitions.
• Expand all tool descriptions to 100-250 characters. Include: (1) what the tool does, (2) when to call it vs similar tools, (3) what it returns or modifies. Example: 'export_block: Export the current block design in JSON (machine-readable), HTML (web-ready), or HCS-1 (Hedera standard) format. Saves to the file system. Use JSON for round-trip imports, HTML for sharing with non-technical users.'
• Document output schemas for all tools. Specify: what fields are returned, their types, whether IDs are included for chaining downstream calls. Example for export_block: {type: 'object', properties: {success: boolean, file_path: string, format: string, size_bytes: integer, error?: string}}
• Add descriptions to all parameters. For validate_block, document what 'block' is inferred from (current editor state? parameter?). For import_block, clarify: 'Full or relative file path to a .json file (max 10MB, must contain valid block definition. Relative paths are resolved from the desktop app's working directory.)'
• Add error handling hints to all tool descriptions. Example: 'If import fails due to invalid JSON, the response will include the parse error and the line number. Use validate_block first to check syntax before importing.'
• For export_block, document where files are saved (user's Downloads? app directory?) and whether the user is prompted for a location. Add a note: 'On success, returns the full file path so the user can find the export.'
