Aembit

Gateway

Identity-based access control for AI agents and MCP servers.

What it solves

MCP agents authenticate to servers with static API keys and long-lived tokens sitting in config files. Aembit replaces those secrets with short-lived, workload-identity-based credentials, so an agent's access to an MCP server is tied to what the workload is, not to a key anyone can copy.

How it works

Aembit issues identity to workloads (agents, services, pipelines) based on attestation — where the workload runs and what it is. A policy layer then decides which MCP servers and tools that identity may reach, and brokers credentials just-in-time instead of storing them on disk.

Pros & cons

Pros

Removes plaintext tokens from MCP client and server configs.
Central policy view of which agents can call which servers and tools.
Fits zero-trust environments that already dislike long-lived secrets.

Considerations

Enterprise sales motion — no self-serve free tier to evaluate quickly.
Adds an identity control plane to your stack; small teams may not need it yet.
Value depends on how much of your agent infrastructure you route through it.

When to choose it

Choose Aembit when you run multiple agents in production, are already uncomfortable with secrets in MCP configs, and have the security team budget for an enterprise identity platform.
