Auth MCP Server

@firebase/auth interop Types. Exposed over MCP by the auth mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

What it actually does

The Firebase JavaScript SDK implements the client-side libraries used by applications using Firebase services. This SDK is distributed via:

Each package in the packages directory, constitute a piece of our implementation. The SDK is built via a combination of all of these packages which are published under the firebase scope on NPM.

Adding it to your client

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.

Its toolset

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

• Prerequisites — The Prerequisites tool exposed by this server
• Yarn — In addition to Node.js we use yarn to facilitate multi package development
• Java — The closure compiler requires a modern Java installation. Java 11+ should be installed: https://www.oracle.com/java/technologies/downloads/#java11
• Introduction — Each package in the packages directory, constitute a piece of our implementation. The SDK is built via a combination of all of these packages which

Caveats

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the auth mcp server does with a few real requests.

When to reach for it

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Auth's toolset — Prerequisites, Yarn, Java and 1 more — is a fair guide to whether it matches your workflow. It is maintained by google-wombot; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
