The MCP tool returned success. The SQLite database disagreed. In this tutorial, I build a deliberately vulnerable local MCP server fixture that violates its own atomic batch contract: one requested row changes, another ID does not exist, and the tool still reports success. Then I run the same request through Cursor, compare the agentâs conclusion with an independent database query, and harden the server so the entire transaction rolls back when any requested job is missing. You will see how to: ⢠reproduce an MCP partial-commit failure ⢠verify tool output against persisted database state ⢠enforce database integrity with row-count checks and transaction rollback ⢠return an MCP tool error instead of a false success result ⢠test both the rejected batch and a legitimate valid batch This is a deliberately authored local fixture, not a discovered Cursor vulnerability, an MCP protocol vulnerability, or evidence that every AI agent behaves this way. It demonstrates a failure class that application code can introduce when an MCP toolâs success response is not tied to its promised outcome. âą CHAPTERS 00:00 MCP success vs. database state 00:15 Why an affirmative tool reply is not proof 00:40 The batch contract and vulnerable fixture 01:30 Proving the partial commit with SQLite 03:00 Cursor vs. an independent database query 05:30 Enforcing atomic rollback in the MCP server 07:00 Testing the failure and the valid batch 08:00 What this evidence doesâand does notâprove đ RESOURCES Evidence ledger: TBD Fixture and commands: TBD #MCP #ModelContextProtocol #AIAgentSecurity
