Overview

AI-generated overview

Dungbeetle is a local MCP server for visual regression and snapshot testing that lets an assistant list test runs, read semantic diffs and review results.

What you can do
List visual regression and snapshot test runs for AI agents and inspect their outcomes. Read semantic diffs to see what changed between snapshots. Review results so an assistant can help triage visual changes. No individual tools are listed in the manifest, so the exact operations are not documented here.
When to use it
Useful when a project runs visual regression or snapshot tests and you want an assistant to help review runs and interpret diffs without leaving the chat. Best suited to teams already using Dungbeetle for visual testing.
Requirements
Runs as a local process over stdio, installed from the npm package dungbeetle-mcp, so Node.js is needed. Authentication is required through DUNGBEETLE_AGENT_TOKEN, minted with the dungbeetle login command, or alternatively DUNGBEETLE_CLIENT_ID with DUNGBEETLE_CLIENT_SECRET. DUNGBEETLE_SERVER_URL is only needed when self-hosting. Desktop only; network access to the Dungbeetle service.
Before you install
The server needs credentials: DUNGBEETLE_AGENT_TOKEN or the DUNGBEETLE_CLIENT_SECRET pair. Treat these as secrets and prefer the scoped, revocable agent token over the client secret. Test run and diff data is sent to the Dungbeetle service, or to your own server when self-hosting. Review actions may change the state of runs, so confirm before approving or dismissing results.

Installation

In SourceWeft

  1. Open Dungbeetle in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

25% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
