export const mcp_list_databases = async (): Promise<ToolResult<DatabaseInfo[]>> => { console.log('Executing mcp_list_databases'); try { const database = getDatabase(); const client = database.client; const { resources: databases } = await client.databases.readAll().fetchAll(); const databasesInfo: DatabaseInfo[] = databases.map(db => ({ id: db.id, etag: db._etag, timestamp: new Date(db._ts * 1000) })); return { success: true, data: databasesInfo }; } catch (error: any) { console.error(`Error in mcp_list_databases: ${error.message}`); return { success: false, error: error.message }; } }; - src/tools.ts:4-16 (registration)Tool registration in MCP_COSMOSDB_TOOLS array, defining name, description, and input schema for the MCP ListTools request.
