This server has critical definition gaps across all 13 tools. While tool names follow verb_noun convention (cashapp_get_balance, cashapp_send_money), descriptions are present but lack LLM-optimization guidance. Most critically: (1) Input schemas are visible and properly typed, but parameter descriptions are minimal (1-2 sentences, often under 50 chars). (2) No output schemas are documented, LLMs cannot infer what fields to expect from responses. (3) No error handling guidance, tools return JSON but lack recovery instructions. (4) Security-critical: cashapp_login exposes credentials as parameters (email_or_phone, password) rather than using server-side injection. (5) cashapp_send_money and cashapp_accept_request are IRREVERSIBLE but lack confirmation/dry-run patterns. (6) No pagination support on list tools (cashapp_get_transactions, cashapp_get_pending_requests). (7) Parameter 'note' is marked required in cashapp_send_money and cashapp_request_money but described as 'optional', contradiction. Baseline: A+ tools average 194 chars description + 72 chars per param; this server averages ~80 chars description + 40 chars per param.

• Move credentials (email_or_phone, password) out of cashapp_login parameters. Inject them server-side via environment variables or a secure vault. Modify the tool to accept only a session_token or require pre-authentication via a separate secure channel.
• Document output schemas for all 13 tools. For each tool, add a 'returns' section in the description or a separate schema field listing field names, types, and meanings. Example: 'Returns {balance: number (USD cents), currency: string, updated_at: ISO8601}'. This enables LLMs to plan downstream calls.
• Add confirmation/dry-run support for irreversible operations. Implement a 'confirm' parameter (boolean, default false) for cashapp_send_money and cashapp_accept_request. When false, return a preview of the action; when true, execute. Or add separate tools: preview_send_money + execute_send_money.
• Fix parameter schema contradictions. For cashapp_send_money and cashapp_request_money, either remove 'note' from the required array (if truly optional) or update the description to 'Required note/memo'. Align schema and description.
• Add pagination and result limits. Implement offset/limit or cursor-based pagination for cashapp_get_transactions and cashapp_get_pending_requests. Return total_count and next_cursor in responses. Cap default limit to 20 and max to 100. Document in tool descriptions.
