This server has severe definition quality gaps. Tool descriptions are present but minimal (10-50 chars, well below the 194-char baseline). Most critically, input schemas are either missing or inferred from code rather than explicitly registered. The execute_action tool accepts generic 'params' and 'metadata' objects with no type constraints, violating the constrained-input pattern. No tool declares what it returns, no error handling guidance, no permission scopes, and no audit trail documentation. Tools like chat_completion and embeddings expose API model selection without enum constraints, inviting hallucinated model names. The webhook handler accepts untyped 'request' and 'headers' dicts. Parameter descriptions lack format/range constraints (e.g., 'amount' in create_charge has no currency validation or min/max). No tool is idempotent-marked. Security is weak: API keys are hardcoded in startup (src/api/main.py line 24-25), not injected. Overall, this reads as a proof-of-concept, not production-grade tooling.

• Add explicit JSON Schema to every tool input. For execute_action, replace generic 'params' object with a discriminated union or specific action-type schemas (e.g., 'openai_params', 'stripe_params'). See constrained-input pattern.
• Document output schemas for all tools. E.g., list_connectors should return [{id: string, name: string, status: ConnectorStatus, supported_actions: string[]}]. LLMs need to know what fields to extract.
• Move API credentials to environment variables or a secrets vault. Remove hardcoded keys from src/api/main.py. Inject via SecretManager at runtime. See secret-injection pattern.
• Add enum constraints to model parameters. chat_completion.model should be enum ['gpt-4', 'gpt-4-turbo', 'gpt-3.5-turbo']. embeddings.model should be enum ['text-embedding-3-small', 'text-embedding-3-large']. Prevents hallucinated model names.
• Add error recovery guidance to tool descriptions. E.g., execute_action: 'If connector not found, call list_connectors() to see available connectors.' See recovery-guide pattern.
