 ## MCP Tools
 
 - `mcp__resources__postgresql_psql` — Execute read-only SQL queries and psql backslash commands (`\dt`, `\d`, `\di`, `\df`, etc.). Args: `resourceId`, `command`, `timeoutMs?`
-- `mcp__resources__postgresql_run_migration` — Run DDL/DML migrations on **managed databases only** (`isManaged=true`). Runs in a transaction; rolls back on failure. Args: `resourceId`, `migration`, `description?`
+- `mcp__resources__postgresql_invoke` — Execute write SQL against managed or external PostgreSQL resources. Args: `resourceId`, `sql`, `params?`, `timeoutMs?`, `description`
+- `run_migration` on the platform MCP server — Run tracked migrations on an application's managed database in app-building/orchestrator sessions. Args: `applicationId`, `migration`, `description`

 ## Tips
 
 - Use parameterized queries (`$1`, `$2`, ...) — never interpolate values into SQL strings
-- `psql` tool is read-only; use `run_migration` for writes (managed DBs) or the TypeScript client for writes (external DBs)
+- `psql` is read-only; use `postgresql_invoke` for data modifications against managed or external PostgreSQL resources
+- Use `run_migration` for tracked schema migrations on an application's managed database
 - The TypeScript client supports full read/write operations regardless of managed status
 - Use `psql` exclusively for read-only tasks. Never use invoke for read only.
