AI agents use transfer_objects to commit financial operations through Postgres — usually the final step of a payment, billing, or trading workflow. A call moves real money.
transfer_objects moves real money, and an autonomous agent will call it with the same confidence it calls a search tool. A misread instruction or an injected prompt is all it takes to drain an account or blow a budget.

Transfer schema (DDL) and/or data from one configured server/database to another (same server, different DB, or fully remote). Builds on the introspection module for DDL extraction with topological ordering. Modes: include=. It is categorised as a Financial tool in the Postgres MCP Server, which means it involves financial transactions. Block by default and require explicit approval.
Register the Postgres MCP server in PolicyLayer and add a rule for transfer_objects: 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 Postgres. Nothing to install.
transfer_objects is a Financial tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the transfer_objects 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 transfer_objects. 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.
transfer_objects is provided by the Postgres MCP server (teja-sudo/postgres-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
