What is the Debugg AI MCP server?

Enable your code gen agents to create & run 0-config end-to-end tests against new code changes in remote browsers via the Debugg AI testing platform. Exposed over MCP by the debugg ai mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

What it actually does

AI-powered browser testing via the Model Context Protocol. Point it at any URL (or localhost) and describe what to test — an AI agent browses your app and returns pass/fail with screenshots.

Its toolset

Everything the assistant can do here goes through one of these:

  • Removed — Replacement
  • search_projects — project {action:"get"} / project {action:"list"}
  • create_project — project {action:"create"}
  • search_environments — environment {action:"get"} / {action:"list"}
  • search_executions — executions {action:"get"\
  • Browser — The Browser tool exposed by this server
  • check_app_in_browser — Runs an AI browser agent against your app. The agent navigates, interacts, and reports back with screenshots. Localhost URLs are auto-tunneled via
  • trigger_crawl — Fires a server-side browser-agent crawl to populate the project's knowledge graph. Localhost URLs tunnel automatically. Returns {executionId, status
  • probe_page — All targets in a batch share one session tunnel, but only same-port (or all-public) batches share a single backend execution — 5 URLs on one port
  • project — Team and repo resolve by either uuid or name (case-insensitive exact match; NotFound if none, AmbiguousMatch if multiple). There is no
  • environment — projectUuid auto-resolves from the git repo when omitted. Per-cred failures surface in credentialWarnings[] without blocking the env op
  • test_suite — The test_suite tool exposed by this server

Adding it to your client

Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.

Configuration

You will need 6 environment variables: DEBUGGAI_API_KEY, DEBUGGAI_API_TOKEN, DEBUGGAI_JWT_TOKEN, DEBUGGAI_API_URL, POSTHOG_API_KEY, DEBUGGAI_MCP_PUBLIC_URL. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

When to reach for it

Among the browser automation options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Debugg AI's toolset — Removed, search_projects, create_project and 11 more — is a fair guide to whether it matches your workflow.

This entry was verified against Debugg AI's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Caveats

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • With 14 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Debugg AI.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the debugg ai mcp server does with a few real requests.

Frequently asked questions

It connects Debugg AI to MCP-compatible AI assistants such as Claude and Cursor, exposing 14 tools (Removed, search_projects, create_project, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Debugg AI directly.
