Real control comes from the permission grant point—that is, the capability set exposed by the MCP server, plus hard spending caps and kill switches that are independent of the prompt; a prompt-level "please be careful" does not constitute control.

UnverifiedMCP's human-in-the-loop authorization mechanism is consistent with the defense logic against prompt injection attacks: even if an attacker induces an agent to issue an unauthorized request, it cannot bypass the manual checkpoint of user consent.75% similarUnverifiedThe specificity of prompts directly affects MCP's willingness to make calls; the more specific the problem description, the more reliably it triggers the corresponding service.74% similarUnverifiedMaintaining a session-level counter on the MCP client and refusing to initiate calls when the limit is exceeded, and enforcing token bucket or sliding window rate limiting on expensive tools on the server side, are common engineering practices for budget control.74% similarUnverifiedExplicit guardrails can be used to restrict MCP server operation permissions, for example by setting a database MCP server to read-only to prohibit destructive operations.73% similarUnverifiedIf the permission-checking logic on the MCP server side is not executed independently for each call but relies on static credentials established when the connection is created, it may bypass the document system's existing ethical wall controls.71% similar
