Getting it into your agent
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.

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 5.1 | $0.00081 | $0.02359 |
| Opus 5.5 | $0.00032 | $0.00944 |
| Sonnet 5.5 | $0.00016 | $0.00472 |
| Haiku 4.5 | $0.00008 | $0.00236 |
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 today.
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.
This is a copy
100% identical to relational-database-mcp-cloudbase — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 216 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 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, ormanagePermissions.
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
_openidand 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:
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

relational-database-mcp-cloudbase is a skill published in the GitHub repository TencentCloudBase/cloudbase-skills (39 stars, last pushed yesterday), licensed MIT. It adds 81 tokens to every session and 2,359 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to relational-database-mcp-cloudbase, differing in 0 lines, and is treated as a copy.
