WHAT IT DOES

What mysql_enable_versioning does on Mysql Mcp

AI agents use mysql_enable_versioning to create or update resources in Mysql Mcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mysql Mcp environment.

RISK

Why mysql_enable_versioning is rated Medium

This tool performs schema modification (adding columns and triggers) which is reversible and creates/modifies data structures rather than executing arbitrary code or destructively removing data. While it affects table structure, it is not irreversible (column and trigger can be dropped), nor does it execute arbitrary commands or involve financial transactions.

From the tool's definition Tool modifies table structure by adding a _version column and auto-increment trigger. Description explicitly states it 'Adds' these schema elements, which are reversible schema modifications characteristic of Write operations.

RECOMMENDED RULE

The rule that runs mysql_enable_versioning safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mysql Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For mysql_enable_versioning, this is the rule to start with:

mysql_enable_versioning Rate-limited

mysql_enable_versioning stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Mysql Mcp, apply this rule, and every mysql_enable_versioning call is checked against it from then on.

Questions about mysql_enable_versioning

What does the mysql_enable_versioning tool do? +

Enable optimistic concurrency control (OCC) on a table. Adds a _version column and an auto-increment trigger. It is categorised as a Write tool in the Mysql Mcp MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on mysql_enable_versioning? +

Register the Mysql MCP server in PolicyLayer and add a rule for mysql_enable_versioning: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mysql Mcp. Nothing to install.

What risk level is mysql_enable_versioning? +

mysql_enable_versioning is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit mysql_enable_versioning? +

Yes. Add a rate_limit block to the mysql_enable_versioning rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block mysql_enable_versioning completely? +

Set action: deny in the PolicyLayer policy for mysql_enable_versioning. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides mysql_enable_versioning? +

mysql_enable_versioning is provided by the Mysql MCP server (oci:docker.io/writenotenow/mysql-mcp:v1.0.0). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
