// WHEN AI AGENTS USE THIS TOOL

AI agents use connect_to_database to create or modify resources in AWS Labs postgres MCP Server. 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.

// WHY ENFORCE A POLICY ON CONNECT_TO_DATABASE

Without a policy, an AI agent could call connect_to_database repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach AWS Labs postgres MCP Server.

// RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the connect_to_database tool do? +

Connect to a specific database and save the connection internally. It is categorised as a Write tool in the AWS Labs postgres MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on connect_to_database? +

Add a rule in your Intercept YAML policy under the tools section for connect_to_database. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the AWS Labs postgres MCP Server MCP server.

What risk level is connect_to_database? +

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

Can I rate-limit connect_to_database? +

Yes. Add a rate_limit block to the connect_to_database rule in your Intercept 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 connect_to_database completely? +

Set action: deny in the Intercept policy for connect_to_database. 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 connect_to_database? +

connect_to_database is provided by the AWS Labs postgres MCP Server MCP server (awslabs.postgres-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
