Manage PostgreSQL Schema and Execute SQL Safely: Development & Operations Tools
Making database changes is risky. One wrong query and you've deleted production data. Or broken a constraint. Or locked a table.
The Development & Operations MCP server bundle makes database changes safer. Ten MCP tools for creating tables, altering schema, backing up data, executing batch operations, and previewing changes. It's your safety net for database operations.
What This Bundle Does
Development and operations require careful handling. Execute SQL statements safely. Create and alter tables. Backup data before changes. Execute batch operations. Preview changes before executing.
This bundle gives you MCP tools for all of it, with safety built in.
Executing SQL Statements Safely
You need to execute SQL. SELECT queries, INSERT statements, UPDATE operations, DELETE operations, DDL changes.
The MCP tools execute any SQL statement safely. Run SELECT queries to retrieve data. Execute INSERT, UPDATE, DELETE operations. Run DDL statements to modify schema. But with safeguards—preview what would be affected first, then execute.
You need to update user emails. Execute an UPDATE statement safely. Preview what would be affected first. Then execute it.
Ask "Update all users with domain example.com to newdomain.com" and the AI previews what would be affected, then executes the update safely.
Creating Tables from Schema Definitions
New tables need schemas. Define columns, types, constraints, indexes.
The MCP tools create tables from schema definitions. Define columns and types. Add constraints and indexes. Create tables safely.
Create a new orders table. Define columns for order_id, user_id, amount, created_at. Add constraints. Create the table.
Ask "Create an orders table with order_id, user_id, amount, and created_at columns" and the AI creates the table with the schema you specify.
Altering Schema Safely
Modifying existing tables is dangerous. Add columns, drop columns, rename columns, change types. One mistake and you've broken something.
The MCP tools perform safe ALTER TABLE operations. Add columns with types and constraints. Drop columns after checking dependencies. Rename columns safely. Check dependencies first, then make changes.
You need to add a phone column to the users table. Check dependencies first. Then add the column safely.
Ask "Add a phone column to the users table" and the AI checks dependencies, then adds the column safely.
Backing Up Data Before Changes
Always backup before making changes. Create backups so you can restore if something goes wrong.
The MCP tools create table backups before making changes. Backup entire tables or specific columns. Restore backups if needed. It's your safety net.
Backup the users table before making changes. Create a backup. Make your changes. Restore if needed.
Ask "Backup the users table" and the AI creates a backup, then confirms it's ready.
Executing Batch Operations in Transactions
Multiple statements need to succeed together. All succeed or all fail. No partial updates.
The MCP tools execute multiple statements in transactions. All statements succeed or all fail. No partial updates. Atomic operations that either work completely or roll back.
You need to update multiple tables together. Execute them in a transaction. All succeed or all fail.
Ask "Update users and orders tables together" and the AI executes both updates in a transaction, then confirms success or rolls back on failure.
Previewing Changes Before Executing
See what would be affected by DELETE or UPDATE operations before executing them. Preview changes to avoid mistakes.
The MCP tools preview what would be affected by DELETE or UPDATE operations. See which rows would be affected. Count affected rows. Then execute safely.
Preview what would be deleted before executing DELETE. See which rows would be affected. Then execute safely.
Ask "Preview what would be deleted if I delete users older than 90 days" and the AI previews affected rows, shows you what would be deleted, then executes if you confirm.
Checking Dependencies Before Changes
Verify dependencies before dropping or altering tables. What depends on this table?
The MCP tools check dependencies before making changes. See what views, triggers, and functions depend on tables. Know what breaks if you change something. Check first, then change.
You want to drop a table. Check dependencies first. See what depends on it. Then drop safely.
Ask "Check dependencies before dropping the old_users table" and the AI checks dependencies, shows you what depends on it, then helps you drop it safely.
How AI Uses This Bundle
When you ask "I need to add a column to the users table," the AI loads the Development & Operations MCP server bundle, uses postgres_get_table_dependencies to check dependencies, uses postgres_backup_table to create backup, uses postgres_alter_table to add column safely, then confirms success.
Ask "Backup and modify the orders table" and it creates backup, shows what would be affected, then executes changes safely.
Want to execute batch operations? "Update users and orders together" triggers transaction execution, then confirms success.
Getting Started
Enable the Development & Operations MCP server bundle in your MCPBundles account. Connect your PostgreSQL database (host, port, database, user, password—one-time setup). Then start asking schema questions. The AI automatically uses the right MCP tools based on what you ask.
