Delete a transaction by ID.
AI agents call delete_transaction to permanently remove resources in Corpus MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes transaction data from a financial portfolio tracking system. Deletion of financial records is irreversible and cannot be undone—a core characteristic of the Destructive category. The impact is high because erasing transactions distorts financial history, cash flow analysis, and portfolio accuracy.
From the tool's definition Tool name 'delete_transaction' and description 'Delete a transaction by ID' explicitly perform irreversible deletion of financial transaction records.
Attacks that exploit this kind of access
Delete a transaction by ID. It is categorised as a Destructive tool in the Corpus MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Corpus MCP Server MCP server in PolicyLayer and add a rule for delete_transaction: 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 Corpus MCP Server. Nothing to install.
delete_transaction is a Destructive 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 delete_transaction 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 delete_transaction. 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.
delete_transaction is provided by the Corpus MCP Server MCP server (mathankarthik18/corpus-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
