AWS MCP Server

Capable, but hard to hand over unsupervised.

Broadest official coverage anywhere, and the hardest auth: IAM roles and SigV4 mean agent permissions need real design, not a token in a config file.

What an agent can do here

AWS maintains 66+ official MCP servers across its services via awslabs — unmatched breadth, matched by unmatched setup cost.

Admin

Agents can change configuration and infrastructure, not just content.

Hosting
Self-run

You run the server process yourself.

Auth

Needs a human

Interactive OAuth only — it cannot be provisioned without someone clicking through.

Blast radius

A wrong call is expensive, public, or irreversible.

What it costs to let an agent act

FreeUsage-metered

Servers are free and open source; you pay for whatever AWS resources the agent touches. IAM configuration is the real cost.
