Set connection timeout
Part of the Mssql server.

AI agents use set_connection_timeout to create or modify resources in Mssql. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call set_connection_timeout repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Mssql.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access set_connection_timeout gives an agent. Each links to the full case and the policy that stops it:
Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Set connection timeout. It is categorised as a Write tool in the Mssql MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mssql MCP server in PolicyLayer and add a rule for set_connection_timeout: 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. Nothing to install.
set_connection_timeout is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the set_connection_timeout 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 set_connection_timeout. 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.
set_connection_timeout is provided by the Mssql MCP server (daedalus/mcp-server-mssql). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
