SQL for Claude, Cursor, ChatGPT & agents

SQL — read-only access to Postgres and MySQL databases via a BYO connection URL

curl -fsSL https://syncorelabs.ai/install.sh | sh

What it does

SQL — read-only access to Postgres and MySQL databases via a BYO connection URL. Run SELECT / WITH / EXPLAIN / SHOW / DESCRIBE statements, list databases / schemas / tables, describe table columns + types + nullability, list indexes, fast COUNT and sample previews, EXPLAIN query plans, and identify the connected server. Read-only enforced at session level; multi-statements blocked. Use when the user mentions SQL, Postgres, MySQL, database, query, schema introspection, table sample, EXPLAIN, or wants to read / explore relational data.

The SQL skill is one of 75+ pre-wired Syncore integrations that any MCP-compatible client — Claude Desktop, Claude Code, Cursor, Windsurf, Codex CLI, and ChatGPT desktop — can call out of the box. You don't configure MCP servers or copy API keys into a JSON file; the Syncore daemon discovers the skill at startup and exposes its tools to whichever AI client is running.

Sample prompts

Once Syncore is installed and SQL is connected, ask your agent something like:

• “Query from SQL.”
• “List databases from SQL.”
• “List schemas from SQL.”

Tools available (10)

• sql__query

  Run a read-only SQL statement (SELECT / WITH / EXPLAIN / SHOW / DESCRIBE) and return columns + rows. Multiple statements are blocked.

• sql__list_databases

  List databases on the server (Postgres: pg_database; MySQL: SHOW DATABASES). May fail on permission-restricted users.

• sql__list_schemas

  List schemas (Postgres) or treat databases as schemas (MySQL)

• sql__list_tables

  List tables in a schema (Postgres) or database (MySQL)

• sql__describe_table

  Get column metadata (name, type, nullable, default, key/extra) for a table

• sql__list_indexes

  List indexes on a table (name, columns, unique, primary)

• sql__count_table

  Convenience: SELECT COUNT(*) FROM <schema>.<table>. Identifiers are validated.

• sql__sample_table

  Convenience: SELECT * FROM <schema>.<table> LIMIT N for a quick preview

• sql__explain

  EXPLAIN a SELECT / WITH query. Postgres returns FORMAT JSON; MySQL returns the table form.

• sql__get_database_info

  Return server version, current database, and current user / role for the connection

How to connect

SQL needs a provider API key to talk to sql. Connect it from the Syncore dashboard:

1. Run curl -fsSL https://syncorelabs.ai/install.sh | sh on macOS / Linux (or the PowerShell command on Windows).
2. Run syncore login to create your account and a device-bound encryption key.
3. Visit syncorelabs.ai/connect and authorize SQL.
4. Run syncore update to sync the skill + credentials to every installed AI client.

Pricing

Free at every Syncore tier. Connect your account once at /connect; the OAuth or API-key credential stays encrypted on your machine and syncs to your other devices via the Syncore vault.
