This server exposes only 1 tool (mempalace_status) with a trivial empty input schema and minimal description. The tool definition is inferred from code rather than explicitly registered via MCP SDK patterns. No parameter descriptions, no output schema documentation, and no error handling guidance. The server acts primarily as an HTTP gateway/proxy to a Python subprocess, not as a direct MCP tool provider. The single exposed tool lacks the rigor expected of production-grade agent tools.

• Expand tool description to 50-200 characters. Include WHAT it does, WHEN to call it (e.g., 'Call before mining to verify the mempalace instance is running'), and WHAT it returns (e.g., 'Returns status object with fields: running (bool), version (string), palace_path (string)').
• Document the output schema explicitly. Define the response structure (e.g., { type: 'object', properties: { running: { type: 'boolean' }, version: { type: 'string' } } }) so LLMs know what fields to expect.
• If mempalace_status truly has no input parameters, document this explicitly in the schema with properties: {} and required: []. Add a description explaining why no inputs are needed.
• Implement error categorization in CallToolRequestSchema handler. Return structured errors: { isError: true, content: [{ type: 'text', text: 'Service unavailable. Retry in 30s.' }], errorCategory: 'retryable' }.
• Consider exposing additional mempalace tools (mine, query, etc.) as first-class MCP tools rather than only via REST endpoints. This would increase the server's utility and allow agents to compose operations.

• Relies on Stateful initialize / Mcp-Session-Id (removed; protocol is stateless) - make each request self-contained
