This server has severe definition quality issues. Tool definitions are inferred from Flask route handlers rather than explicitly registered via MCP protocol. No input schemas are visible in the source code, parameters are documented in descriptions only, not in structured JSON Schema. Descriptions are present but minimal (10-50 chars), below the 194-char baseline for production tools. Critical issues: (1) 15 tools but only ~6 unique endpoints (get_fgrid, inverter, meter, curtail, charge, should_curtail), the rest are duplicates with identical names ('inverter', 'meter', 'curtail', 'fgrid' appear 2-3 times each), creating ambiguity for LLM tool selection. (2) No explicit tool registration visible, tools appear to be inferred from Flask routes, not declared via MCP ToolDefinition messages. (3) Parameters lack type constraints (enums, ranges, patterns). (4) No output schemas documented. (5) Error handling is absent, no recovery guidance, no categorization of errors as retryable vs fatal.

• Rename duplicate tools to include agent/resource context: 'get_inverter_sa1', 'get_inverter_sa2', 'get_meter_sa1', 'get_meter_sa2', 'curtail_sa1', 'curtail_sa2', 'get_fgrid_solinteg', 'get_fgrid_dynamic', 'get_fgrid_manual'. This eliminates ambiguity and lets LLM select the correct endpoint.
• Explicitly register all tools via MCP ToolDefinition messages with full JSON Schema input schemas. Example: { 'name': 'get_generation_and_consumption', 'description': '...', 'inputSchema': { 'type': 'object', 'properties': { 'inverter_url': { 'type': 'string', 'description': 'URL of inverter endpoint (e.g., http://localhost:5001/inverter)' }, 'meter_url': { 'type': 'string', 'description': 'URL of meter endpoint (e.g., http://localhost:5001/meter)' } }, 'required': ['inverter_url', 'meter_url'] } }
• Expand descriptions to 100-200 chars with WHEN/WHY context. Example: 'Retrieve current grid frequency from SolInteg API to determine if curtailment is needed. Call this first to check if fgrid exceeds the 50 Hz threshold before triggering solar agent shutdown or battery charge.'
• Document output schemas for each tool. Example for get_generation_and_consumption: 'Returns { generation: number (kWh), consumption: number (kWh) }'. For get_fgrid: 'Returns { fgrid: number (Hz, range 48.0-60.0) }'.
• Add error handling with recovery guidance. Example: 'If inverter_url is unreachable, return { error: 'Inverter unreachable at {url}. Verify the URL and network connectivity, then retry.' }' instead of silent failures or generic exceptions.
