Server has 9 tools with basic naming (verb_noun pattern mostly followed) and descriptions present. However, critical gaps emerge: parameter descriptions are minimal or absent in most tools, input schemas lack detail (many parameters have only type and description, no constraints), and output schemas are not documented. The fetch tool performs writes but lacks confirmation/dry-run patterns. Error handling is not visible in the provided code. Tool descriptions are adequate (50-100 chars) but parameter-level documentation is sparse. No tool annotations (readOnlyHint/destructiveHint) despite clear risk classifications. This is a typical community server with functional but incomplete definitions.

• Add output schema documentation to every tool. Example: 'Returns: {endpoints: [{url: string, category: string, price: number}], total: number}'. This enables LLMs to plan downstream calls.
• Expand parameter descriptions with format and constraints. For 'chain', write: 'Blockchain chain (enum: base, solana, casper)'. For 'url', write: 'HTTPS endpoint URL (must start with https://)'. For 'method', write: 'HTTP method (enum: GET, POST, PUT, DELETE, PATCH)'.
• Add tool annotations to fetch: set destructiveHint=true and idempotentHint=false. Add readOnlyHint=true to all other tools. This signals to LLMs which tools are safe to retry.
• Implement a dry-run or confirmation pattern for fetch. Add optional 'dry_run' parameter (boolean, default false) so agents can preview the request before executing. Return the would-be response without side effects.
• Add error handling guidance. Document what errors each tool can return (e.g., 'Returns 404 if URL not found. Try discover_url() first to validate the endpoint exists.') and recovery steps.
