Implementation Reference
- src/tools/steampipe_table_list.ts:22-96 (handler)The handler function that queries the database to list available Steampipe tables, optionally filtered by schema and table name pattern using ILIKE.
handler: async (db: DatabaseService, args?: { schema?: string; filter?: string }) => { if (!db) { return { content: [{ type: "text", text: "Database not available. Please ensure Steampipe is running and try again." }], isError: true }; } try { // Check if schema exists if specified if (args?.schema) { const schemaQuery = ` SELECT schema_name FROM information_schema.schemata WHERE schema_name = $1 `; const schemaResult = await db.executeQuery(schemaQuery, [args.schema]); if (schemaResult.length === 0) { return { content: [{ type: "text", text: `Schema '${args.schema}' not found` }], isError: true }; } } // Build the query based on provided arguments let query = ` SELECT DISTINCT table_schema as schema, table_name as name, obj_description(format('%I.%I', table_schema, table_name)::regclass::oid, 'pg_class') as description FROM information_schema.tables WHERE table_schema NOT IN ('information_schema', 'pg_catalog') `; const params: any[] = []; let paramIndex = 1; if (args?.schema) { query += ` AND table_schema = $${paramIndex}`; params.push(args.schema); paramIndex++; } if (args?.filter) { query += ` AND table_name ILIKE $${paramIndex}`; params.push(args.filter); // Use the filter pattern as-is since it already includes wildcards } query += " ORDER BY table_schema, table_name"; const result = await db.executeQuery(query, params); return { content: [{ type: "text", text: JSON.stringify({ tables: result }) }] }; } catch (err) { logger.error("Error listing tables:", err); return { content: [{ type: "text", text: `Failed to list tables: ${err instanceof Error ? err.message : String(err)}` }], isError: true }; } } - Input schema defining optional 'schema' and 'filter' parameters for the tool.
