Multicorn Shield – Permissions, approvals & audit trails for AI agents

Summary: Multicorn Shield adds a permission layer for AI agents by intercepting tool calls and blocking unauthorized actions. It provides real-time approval requests, time-limited access, spending controls, and tamper-proof audit logs, enhancing control and safety for AI integrations.

What it does

It intercepts every AI agent tool call before execution, verifies permissions, and blocks unauthorized actions. It functions as an MCP proxy with a two-minute setup and is open source.

Who it's for

Designed for users and developers integrating AI agents who need granular control over tool and data access.

Why it matters

It prevents AI agents from executing unapproved actions by enforcing permissions outside the model’s context window, addressing critical safety gaps.
