List currently running processes/queries in the database
AI agents call mysql_processlist to retrieve information from Multi-Database MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation to retrieve the current state of running queries and processes. It has no side effects, does not modify data, and is used for monitoring and diagnostic purposes. The 'List' verb clearly indicates data retrieval. No blast radius if misused by an AI agent beyond potential information disclosure of what queries are running.
From the tool's definition Tool name 'mysql_processlist' and description 'List currently running processes/queries in the database' indicate a query/monitoring operation that retrieves information about active database processes without modifying data.
Attacks that exploit this kind of access
List currently running processes/queries in the database. It is categorised as a Read tool in the Multi-Database MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Multi-Database MCP Server MCP server in PolicyLayer and add a rule for mysql_processlist: 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 Multi-Database MCP Server. Nothing to install.
mysql_processlist is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the mysql_processlist 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_processlist. 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_processlist is provided by the Multi-Database MCP Server MCP server (nam088/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
