What is relational-database-mcp-cloudbase?

A guide for using CloudBase tools to inspect and manage MySQL databases, including their tables and access rules.

Use it to query or run SQL, create or remove a MySQL database, set up tables, and manage database permissions.

It helps an agent handle database operations in the right order, such as checking that MySQL is ready before changing it.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00094	$0.02201
Opus 5	$0.00047	$0.01100
Sonnet 5	$0.00019	$0.00440
Haiku 4.5	$0.00009	$0.00220

Security

Grade A, and why

relational-database-mcp-cloudbase scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 215 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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 agent must inspect SQL data, execute SQL statements, provision or destroy MySQL, initialize table structure, or manage table security rules through MCP tools.

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 checking whether MySQL is provisioned and ready.
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.

When to use this skill

Use this skill when an agent needs to operate on CloudBase Relational Database via MCP tools, for example:

Inspecting or querying SQL data
Provisioning MySQL for an environment
Destroying MySQL for an environment
Polling MySQL provisioning status
Modifying data or schema (INSERT/UPDATE/DELETE/DDL)
Initializing tables and indexes after MySQL is ready
Reading or changing table permissions

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
