This is a web application integrating MCP clients, not an MCP server itself. The four 'tools' are actually SvelteKit route handlers that expose web APIs for MCP interaction. Tool definitions lack proper input schemas (parameters are inferred from usage), descriptions are present but generic, and there is no structured output documentation. The mcp_agent_execution tool exposes API keys as parameters, violating secret injection patterns. Error handling is absent from the route implementations. Overall definition quality is poor due to missing schemas, lack of parameter descriptions beyond names, and security violations.

• Move OpenRouter API key to server-side environment variable (process.env.OPENROUTER_API_KEY). Do NOT expose it as a tool parameter. See pattern:secret-injection.
• Add explicit MCP tool registration with complete JSON Schema for all inputs. Define type, description, enum, and constraints for every parameter. Reference: pattern:constrained-input.
• Document output schema for each tool. Include example responses so LLMs know what fields to expect and how to chain tool calls.
• Rename tools with action verbs: 'mcp_client_tools' → 'list_mcp_server_tools', 'mcp_agent_execution' → 'execute_mcp_agent', 'agent_script_generation' → 'generate_applescript_from_transcript'.
• Implement error handling with actionable recovery messages. Example: 'MCP server unreachable. Retry in 5 seconds or check server URL.' See pattern:recovery-guide.
• Add parameter constraints: transcript (min 1 char, max 10000 chars), theme (enum: light | dark), openrouterKey removed entirely.
• For agent_script_generation, document the denylist (what actions are blocked?) and return both script code AND a safety report indicating which actions passed/failed denylist checks.
• Consider splitting mcp_agent_execution into two tools: 'discover_mcp_tools' (fetch available tools) and 'execute_agent_plan' (run the agent). Follows pattern:tool single responsibility.
• Add per-tool metadata: READ_ONLY hint for mcp_client_tools and discovery calls, WRITE hint for agent execution, IRREVERSIBLE for script generation (AppleScript can perform destructive OS actions).
