The idea in one minute

Start with meaning, then move to detail.

This lesson explains ACP Host Integration as part of getting started with Hermes correctly. You will learn what it does, when it matters, and the smallest safe test that proves it works.

If you are new

If you are new, do not memorize names. Focus on three questions: what problem does this solve, what access does it need, and how can you verify the result?

For hands-on use

For practice, inspect the first example, identify its effects, run it on test data, and compare the result with the source claim.

For specialists

For advanced readers, inspect What Hermes exposes in ACP mode, Installation, Launching the ACP server, then verify failure modes and version compatibility.

What do you need first?

No prior experience is required; follow the steps on a safe test setup first.

What will you know?

A clear outcome before you read.

  • Understand ACP Host Integration without assumed prior knowledge.
  • Separate the source description from what still needs testing in your environment.
  • Read the first command and identify its inputs and outputs before copying it.

Examples from the official page

Copy only after you understand the effect.

cd ~/.hermes/hermes-agent && uv pip install -e '.[acp]'

Try it now

Read the first command and identify its inputs and outputs before copying it.

Match every command to your installed Hermes version, review the files and accounts it can reach, and use non-sensitive data for the first test. If this explanation differs from the source, the official source wins.

Knowledge check

Three decisions before completion.

1. What is the source of truth when “ACP Host Integration” changes?
