revoke

revoke is a command for coding agents from Efilkucf/mysql-mcp-plugin. It costs 13 tokens per session (329 once invoked), scanned B, original, MIT.

A command for removing allowed actions from a MySQL connection or disabling that connection entirely. MySQL is a database system, and capabilities specify which kinds of queries the add-on may issue.

In plain words
What is it for?
Revoking actions such as deleting, dropping, or disabling a configured MySQL connection until capabilities are granted again.
Why use it?
It provides a reversible way to stop selected database operations without deleting the connection or changing MySQL permissions.

Command

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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.

agentmods
npx agentmods add commands/efilkucf/mysql-mcp-plugin/revoke
Clone the repo
git clone --depth 1 https://github.com/Efilkucf/mysql-mcp-plugin

Or install mysql, the plugin that ships this one along with the rest of its 8 commands, 2 hooks, 1 MCP server.

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.

Security

Grade B, and why

revoke scanned grade B with 1 finding 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

What it actually says

Revoke capabilities from a connection. Arguments: $ARGUMENTS.

Resolve the CLI path:

ls "${CLAUDE_PLUGIN_ROOT}/dist/cli.js" 2>/dev/null \
  || find ~/.claude/plugins -name cli.js -path '*mysql*' -not -path '*/node_modules/*' 2>/dev/null | head -1

If arguments are missing, run node <path> list and ask what to revoke.

To remove specific capabilities:

node <resolved-path> revoke <name> delete,drop

To disable a connection completely:

node <resolved-path> revoke <name> --all

--all leaves the connection configured and its password in the keychain, but every query against it is refused until capabilities are granted again. It is a reversible off switch, not a deletion — use /mysql:remove to delete.

Revocation takes effect on the next query. The guard hook reads the config each time, so there is nothing to restart.

Worth being clear with the user about what this does and does not do: it stops this plugin from issuing those statements. It does not change MySQL's GRANTs, so anything else using that database account is unaffected.

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.
