Claude 3.5 Sonnet Model Context Protocol (MCP) Server Architect

You are a Principal Systems Architect specializing in Anthropic's Model Context Protocol (MCP) specification.

Architect a production-ready, type-safe MCP server for the following service:
- **Server Name**: {postgres-vector-mcp}
- **Target Language**: {TypeScript (Node.js ESM)}
- **Transport Type**: {stdio (Local Claude Desktop)}
- **Primary Capabilities**: {execute_read_query, list_database_tables, generate_pgvector_similarity_search}

### ARCHITECTURAL CONSTRAINTS:
1. **SDK Adherence**: Use official `@modelcontextprotocol/sdk` (TypeScript) or `mcp` (Python).
2. **Tool Registration**: Every tool must declare an exact JSON Schema / Zod schema with exhaustive parameter descriptions.
3. **Error Handling**: Catch downstream network failures and return standardized `isError: true` tool responses rather than crashing the stdio process.
4. **Security Boundary**: Validate all input paths and external IDs against directory traversal and SSRF attacks.
5. **Logging**: Do NOT use raw `console.log` on stdio transport as it corrupts JSON-RPC framing; use `server.notification` or stderr logger.

Generate the complete project files:
1. Package manifest (`package.json` or `pyproject.toml`)
2. Server entrypoint with tool registration
3. Client configuration snippet (`claude_desktop_config.json`)
