What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Connection: Runs in the cloud
Transport: Streamable HTTP
Category: Other
You need to fill in: Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on the maker’s server: what you ask it goes through their server.
You fill in yourself: Authorization

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Runs in the cloudNothing to install; it connects over the internet

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http 46a https://46a.co/mcp --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "46a": {
      "url": "https://46a.co/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "46a": {
      "type": "http",
      "url": "https://46a.co/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Common questions

Is 46a MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 19 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, Zendesk

46a MCP Server

Live control of a 46a project open in a user's browser, via MCP. Lets an MCP client read live application/DOM state and perform editor actions in real time.

Installation

As an HTTP (configured outside mcpServers)

How to use the MCP connector, for hints ask claude "claude: show me where to configure mcpServers?"

Add the server URL as a custom connector (claude.ai: Settings → Connectors → Add custom connector; Claude Code: claude mcp add --transport http 46a-mcp https://46a.co/mcp).

Configure entry with OAuth

Local claude MCP configuration to use oauth (default)

"mcpServers": { "46a-mcp-http-oauth": { "type": "streamable-http", "url": "https://46a.co/mcp" } } }

Configure a entry with basic auth

Local claude MCP configuration to use basic auth instead of oauth.

"mcpServers": { "46a-mcp-http-basic-auth": { "type": "streamable-http", "url": "https://46a.co/mcp", "headers": { "Authorization": "Basic " } } } }

Configure stdio process (you probably won't need this)

"mcpServers": { "46a-mcp-stdio": { "command": "node", "args": ["src/stdio.js"], "cwd": "/Users/jroy/src/46a/mcp", "env": { "REMOTE_URL": "https://46a.co/mcp", "EMAIL_OR_USERNAME": " ", "PASSWORD": " " } } } }

Running (or this)

node src/http.js

Connecting a client

A. Configure a custom connector, or B. Add entries (as above) to .mcp.json or other Claude config location, using either basic auth or OAuth (default), or C. Configure a local entry for the stdio-based process (see above)

Workflow

listConnections → pick a live connectionId.
callTools and/or inject against that connectionId.

connectionId is ephemeral and orphans on page reload — re-list when in doubt.

Tools

Client discovers tools via tools/list.

listConnections — list live browser connections. Optional emailOrUsername filter. Returns connectionId -> { user, project }.
callTools — run 46a tool calls against one connection: { connectionId, request: { v: 't', calls: [...] } }.
inject — run code in the connection's browser session: { connectionId, request: { v: 'j', code } }. code must be a single expression evaluating to a Promise.
hello_world — connectivity test tool.

callTools call surface

request.calls

add_object — add a single object (Circle, Square, _basic.text, _basic.plainText, _basic.html, SVG).
add_objects — batched add_object, preferred for creating many objects at once.
make_object_from_html — add an object from a raw HTML snippet.
getSelectorData — read application state (page, workspace, project, user, objects, logs).
doAction — perform an editor action (undo/redo, open editor, select objects, zoom, change page, patch object fields, project/page lifecycle, etc).
createImage — generate an image via DALL-E and add it to the project.
delegateAI — delegate a task to another assistant.
uiInteraction — create a UI widget/interaction in the chat thread or UI.
