AI Agent Access Control - Least-Privilege Tool Permissions
An over-permissioned agent is a breach waiting to happen. Declare exactly which tools and data each agent may touch, and Agentshield denies everything else at the boundary.
Direct answer
AI agent access control is the practice of restricting which tools an agent may call and which data it may read or write, enforced at the action boundary. With Agentshield you set per-agent permissions: an allowlist of tools, scoped resources, and read or write rights. Any call outside that scope is denied before it executes, so a compromised or confused agent physically cannot reach a tool or dataset you did not grant it. This is least privilege applied to agents.
Least-privilege by default
Grant each agent only the tools and data it needs. Everything else is denied, so the blast radius of a hijack is whatever you explicitly allowed, nothing more.
Scoped to the resource
Permissions go beyond the tool to the resource: this agent may read these tables, send to these recipients, write to this bucket, and no further.
Enforced at the boundary
Access checks run in the action path, not in fragile agent code, so an injected or buggy agent cannot escalate its own permissions.

AI gateway
An AI gateway is the single point every agent request passes through. Make it the place you enforce security: inspect inputs, gate tools, watch actions, and log everything.

MCP lets agents call external tools, and a poisoned tool output can hijack the agent. Agentshield inspects MCP traffic and enforces which servers and tools each agent may use.

A coding agent runs commands, edits files, and calls tools with real credentials. Scope what it can touch, gate the dangerous actions, and log every move.

Support agents read messages from strangers and can issue refunds and touch accounts. Inspect every message, protect customer data, and gate the actions that move money.
