What mysql_migration_apply does on Mysql Mcp
AI agents invoke mysql_migration_apply to trigger actions in Mysql Mcp. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why mysql_migration_apply is rated High
This tool executes arbitrary migration SQL including DDL statements against a MySQL database. DDL statements (CREATE, ALTER, DROP, etc.) auto-commit and cannot be rolled back, making this effectively irreversible in many cases. The blast radius is critical — a misused migration could alter or destroy schema structure across the entire database, affecting all dependent applications and data.
From the tool's definition 'Execute migration SQL and record it atomically' and 'MySQL DDL statements cannot be rolled back, they commit the current transaction'
Attacks that exploit this kind of access
The rule that runs mysql_migration_apply 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_migration_apply, this is the rule to start with:
mysql_migration_apply stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Mysql Mcp, apply this rule, and every mysql_migration_apply call is checked against it from then on.
Questions about mysql_migration_apply
Execute migration SQL and record it atomically. Note: MySQL DDL statements cannot be rolled back, they commit the current transaction. It is categorised as a Execute tool in the Mysql Mcp MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Mysql MCP server in PolicyLayer and add a rule for mysql_migration_apply: 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.
mysql_migration_apply is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the mysql_migration_apply 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.
Set action: deny in the PolicyLayer policy for mysql_migration_apply. 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.
mysql_migration_apply 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.
