Server has 9 well-named, read-only tools with consistent verb_noun naming (search_*, get_*, list_*). All tools have descriptions (avg 156 chars, within baseline 34-392). Input schemas are present and properly typed with required fields declared. However, output schemas are completely undocumented, LLMs cannot plan downstream calls or extract structured data. Parameter descriptions lack constraints (no enums for set_aside codes, no min/max for limit/days). Error handling is minimal; no recovery guidance or actionable error messages visible in code. No tool annotations (readOnlyHint, idempotentHint). Missing pagination details despite tools returning lists.

• Document output schema for each tool. Example for search_grants: {type: 'object', properties: {grants: {type: 'array', items: {type: 'object', properties: {opportunity_id, title, agency, close_date, award_range, synopsis}}}, total_count: {type: 'integer'}, next_cursor: {type: 'string'}}}
• Add enum constraints to set_aside parameter: enum: ['SDVOSB', 'WOSB', 'SBA', 'HZC', 'SBP']. Add min/max to limit (1-50) and days (1-365) parameters.
• Add readOnlyHint: true to all 9 tools in InputSchema to signal safety to agents.
• Implement pagination: add offset/limit/total_count to list responses. Document in tool descriptions: 'Returns up to 50 results; use offset for pagination.'
• Add error handling with actionable messages. Example: if agency not found, return 'Agency "XYZ" not found. Try search with partial name or call list_agencies() first.' instead of bare 404.
