This server proxies tool definitions from a remote Etch service. The single tool 'dynamic_tools_from_remote' is inferred rather than explicitly registered with a schema. No input schema is visible in the source code. The description is generic and does not explain what parameters the tool accepts, what it returns, or when to use it. Tool definitions are fetched at runtime from a remote endpoint, making static analysis impossible. The server acts as a transparent proxy with no local tool definitions, schemas, or parameter documentation.

• Cache and expose remote tool schemas locally. After fetching tools from the Etch service, store their schemas in memory and return them via list_tools() with full inputSchema, description, and parameter details. This enables static analysis and LLM planning.
• Add parameter descriptions to dynamically fetched tools. When caching remote tool definitions, enrich each parameter with a description field extracted from the remote response or inferred from the parameter name and type.
• Implement error recovery guidance. Wrap remote tool call failures with actionable error messages: 'Tool call failed: {error}. Check that all required parameters are provided and match the expected types. Available tools: {tool_list}'.
• Document the proxy architecture in the tool description. Update the generic description to: 'Proxy tool that forwards calls to the remote Etch service. Available tools are dynamically fetched from etch.systems/mcp. Call this tool with the name and arguments of any Etch tool you want to invoke.'
• Add per-parameter type and constraint documentation. If the remote Etch service returns parameter schemas, parse and expose them in the local tool definitions so LLMs understand valid inputs.
