Relational Database MCP Cloudbase

Sibling skills (local only)

Sibling CloudBase skills ship beside this skill. Use local relative paths such as ../auth-tool-cloudbase/SKILL.md.

If a referenced sibling skill file is missing from this environment, ask the user to install the full CloudBase plugin (or the missing skill). Do not HTTP-fetch remote skill or protocol markdown into the agent context.

Activation Contract

Use this first when

• The environment already has a CloudBase MySQL instance, and the agent must inspect that instance, run SQL, change schema, manage table security rules, or destroy it through MCP.
• Do not choose this skill for a new relational database. New relational work uses postgresql-development-cloudbase.

Read before writing code if

• The task includes queryMysqlDatabase, manageMysqlDatabase, queryPermissions, or managePermissions.

Then also read

• Web application integration -> ../relational-database-web-cloudbase/SKILL.md
• Raw HTTP database access -> ../http-api-cloudbase/SKILL.md

Do NOT use for

• Frontend or backend application code that should use SDKs instead of MCP operations.

Common mistakes / gotchas

• Initializing SDKs in an MCP management flow.
• Running write SQL or DDL before confirming the environment already has a ready MySQL instance.
• Trying to create a MySQL instance through MCP. Provisioning has been retired from the tool surface: new environments use PostgreSQL, and instances are only created in the console.
• Treating document database tasks as MySQL management tasks.
• Skipping _openid and permissions review after creating new SQL tables.
• Destroying MySQL without explicit confirmation or without checking whether the environment still needs the instance.
• Using getConnectionInfo (or inferred host/password) to build a default TCP client for new apps. Prefer SDK / runQuery / runStatement; TCP credentials are an explicit migration exception only.
