AI agents use complete_database_migration to create or modify resources in Neon. 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 complete_database_migration 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 Neon.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Complete a database migration when the user confirms the migration is ready to be applied to the main branch. This tool also lets the client know that the temporary branch created by the. It is categorised as a Write tool in the Neon MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Neon MCP server in PolicyLayer and add a rule for complete_database_migration: 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 Neon. Nothing to install.
complete_database_migration 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 complete_database_migration 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 complete_database_migration. 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.
complete_database_migration is provided by the Neon MCP server (@neondatabase/mcp-server-neon). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
