AI agents call list-databases to retrieve information from MSSQL MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and enumerates existing databases without modifying, executing against, or destroying any data. This is a straightforward Read operation with minimal risk—useful for exploration but no side effects. Low severity because knowing which databases exist is generally low-risk information disclosure.
From the tool's definition Tool name 'list-databases' and description indicating it lists user databases on the server. This is a retrieval operation with no data modification or deletion.

Register the MSSQL MCP Server MCP server in PolicyLayer and add a rule for list-databases: 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 MSSQL MCP Server. Nothing to install.
list-databases 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 list-databases 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 list-databases. 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.
list-databases is provided by the MSSQL MCP Server MCP server (nakiriyuuzu/mssql-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
