Crush + Docker MCP 🐳

We teamed up with Docker to natively integrate the Docker MCP Catalog into Crush and—if we do say so ourselves—it rocks!

There are some CLI improvements and bug fixes in this release, too. Let’s get to it!

Suck in MCPs automatically with Docker Desktop

As we were saying, the big feature in this release is an integration with the Docker MCP Catalog.

During a conversation, Crush and Docker work together to pull in relevant MCPs on demand. Working with Postgres? Building a robot? Going deep on ARM? Crush and Docker will load in in the MCP you need, when you need it (and yes, Crush will still ask for permission).

You just need to have Docker running and enable it in the command palette (ctrl+p).

This is just a short introduction. Read more in the blog post!

New aliases

We added a couple short aliases for our CLI commands:

crush run -> crush r
crush session -> crush s

`--session` and `--continue`

In a recent release, we added --session and --continue flags for crush run.

These flags are now also available for the interactive mode, so you can just run crush --continue to automatically open the last chat, or crush --session {session-id} to automatically open a specific session.

Anthropic + Vertex fix

We fixed an issue authenticating with Anthropic via Google Vertex when using service account JSON keys (charmbracelet/fantasy#157).

Verifying the artifacts

First, download the checksums.txt file and the checksums.txt.sigstore.json file files, for example, with wget:

wget 'https://github.com/charmbracelet/crush/releases/download/v0.51.0/checksums.txt'
wget 'https://github.com/charmbracelet/crush/releases/download/v0.51.0/checksums.txt.sigstore.json'

Then, verify it using cosign:

cosign verify-blob \
  --certificate-identity 'https://github.com/charmbracelet/meta/.github/workflows/goreleaser.yml@refs/heads/main' \
  --certificate-oidc-issuer 'https://token.actions.githubusercontent.com' \
  --bundle 'checksums.txt.sigstore.json' \
  ./checksums.txt

If the output is Verified OK, you can safely use it to verify the checksums of other artifacts you downloaded from the release using sha256sum:

sha256sum --ignore-missing -c checksums.txt

Done! You artifacts are now verified!
