Connect an assistant to Mobster Remote

Every assistant uses the same URL:

https://remote.mobster.dev/mcp

Turn on Remote in Mobster for Mac first (Turn it on). An assistant that signs in sends you to Mobster’s sign-in page, where you sign in with the account Mobster uses (Apple, Google, GitHub or an email code) and choose the iPhone, then Mobster asks you on your Mac before the app is connected (Connect an app). An assistant that takes only a key uses a Remote key you make in Mobster for Mac. Either way, approvals for sends, buys, posts and deletes stay in Mobster on your Mac. An assistant on the same Mac as Mobster, such as Claude Desktop or Claude Code, doesn’t need Remote: it can use Mobster’s local MCP server (Add Mobster to your agent).

Mobster Remote is new. On 8 Oct 2026 we hadn’t yet connected any of these assistants to it. Each section follows the vendor’s own documentation as we read it that day, says which, and is marked “not yet run by us” until we have. If a step looks different for you, write to support@radish.software.

Claude

Claude on the web, Claude Desktop and the Claude apps for iPhone and Android share their connectors. Every call comes from Anthropic’s cloud (160.79.104.0/21), even from the phone app, which is why Claude needs Remote to reach Mobster on your Mac.

Add the connector

In Claude, go to Customize › Connectors, choose + Add, then Add custom connector. On a Team or Enterprise plan, an Owner adds it for the organization in Organization settings › Connectors (Add, then Custom, then Web), and you choose Connect beside it in Customize › Connectors.

Enter the URL

Name it Mobster and enter https://remote.mobster.dev/mcp. If the dialog asks how people sign in, choose Sign in now, and for the OAuth client choose Use Claude’s published identity. Leave the client ID, the secret and the request headers empty. Choose Add.

Claude opens “Connect Claude to Mobster”. Sign in, choose the iPhone and Continue, then choose Allow in Mobster on your Mac.

Use it in a chat

In a chat, + › Connectors turns Mobster on or off for that conversation. Ask for a task: “Use Mobster to check what’s on my calendar tomorrow.”

The Free plan allows one custom connector. Remove it in Customize › Connectors, and remove Claude in Mobster’s Settings › Remote too. Checked against Anthropic’s docs on 8 Oct 2026 (“Add a connector that isn’t in the directory” and “Authentication for connectors”); not yet run by us.

Claude Code

On the Mac where Mobster runs, add mobster mcp instead (Add Mobster to your agent): it’s local and needs no Remote. On another computer:

claude mcp add --transport http mobster https://remote.mobster.dev/mcp

Then run /mcp in Claude Code and sign in in the browser. Claude Code signs in from a program on your computer, so Mobster’s sheet says “A program on the computer you signed in from” instead of a domain. Checked against Anthropic’s Claude Code docs on 8 Oct 2026; not yet run by us.

ChatGPT

ChatGPT connects to custom MCP servers on the web, and only by signing in: it can’t send a key.

Add a custom MCP server

Open ChatGPT Plugins, choose the plus button, then Add custom MCP server.

Fill it in

Name it Mobster and give it a description, such as “Runs tasks on my iPhone”. Under Connection, choose Public endpoint and enter https://remote.mobster.dev/mcp. For authentication, choose OAuth.

Create it

Read the warning, choose I understand and want to continue, then Create as a plugin. ChatGPT shows Mobster’s tools.

Sign in on “Connect ChatGPT to Mobster”, choose the iPhone and Continue, then choose Allow in Mobster on your Mac.

OpenAI’s pages don’t name the plans that can add custom MCP servers, and guides from September 2026 disagree: Business and Enterprise or Edu workspaces can, and Plus and Pro may not. Your workspace’s policy applies too. If ChatGPT doesn’t offer Add custom MCP server, your plan or workspace doesn’t allow it yet. Checked against OpenAI’s docs on 8 Oct 2026 (“Connect from ChatGPT” and the Apps SDK’s authentication page); not yet run by us.

Poke

Poke can sign in or use a key. Signing in needs nothing copied: you allow Poke on your Mac like any other app.

Add the integration

Open poke.com/integrations/new, which fills in the name and the URL. Or enter them yourself: Name Mobster, MCP Server URL https://remote.mobster.dev/mcp.

Choose how it signs in

To sign in, leave API Key empty. To use a key, make a Remote key named Poke and paste it into API Key.

Create it

Choose Create Integration. Poke connects and finds Mobster’s tools. If it signs in, allow it in Mobster on your Mac.

From a terminal, the same with Poke’s command line:

npx poke@latest mcp add https://remote.mobster.dev/mcp -n "Mobster"
npx poke@latest mcp add https://remote.mobster.dev/mcp -n "Mobster" -k "$MOBSTER_REMOTE_KEY"

The first signs in. The second uses a Remote key, which Poke sends as Authorization: Bearer. Never put the key in Poke’s link: links end up in browser history. Poke reads your texts and email. That’s why Mobster never asks for approvals there: when Poke says a task is waiting for you, answer it in Mobster on your Mac. Checked against Poke’s docs on 8 Oct 2026 (“MCP Servers”); not yet run by us.

Raycast

Open Install MCP Server

In Raycast on your Mac, search for Install MCP Server, or use Install New Server in Manage MCP Servers.

Fill in the form

Name Mobster, Transport HTTP, URL https://remote.mobster.dev/mcp, OAuth Type Dynamic. Leave HTTP Headers empty.

Install and sign in

Choose Install MCP Server (⌘↵), then Sign In. Allow Raycast in Mobster on your Mac.

Raycast for iOS takes HTTP servers too. Checked against the Raycast manual on 8 Oct 2026 (“Model Context Protocol”); not yet run by us.

Grok

On grok.com, open Connectors, choose New Connector, then Custom. Enter https://remote.mobster.dev/mcp and complete the sign-in it asks for. xAI’s page doesn’t say which sign-in the form offers. If it offers to sign in, do that and allow Grok in Mobster on your Mac. If it asks for a key or a header, make a Remote key and send it as Authorization: Bearer and the key. xAI says connectors are open to every Grok user; on Business and Enterprise plans, an admin provisions a connector in the cloud console before members can use it. Likely to work. Checked against xAI’s docs on 8 Oct 2026 (“Connectors”); not yet run by us.

Grok Bot

In a terminal on a computer where Grok Bot is set up:

grok mcp add --transport http mobster https://remote.mobster.dev/mcp

Mobster then shows in the Bot’s connector marketplace. Install it there, sign in in the browser, and allow Grok in Mobster on your Mac. Grok Bot’s Mac app can also run commands on your Mac (Settings › General › Bot › Execution on Local Computer, which asks every time by default). On the Mac where Mobster runs, it can hand Mobster a task with mobster chat and no Remote at all. Approvals for that task still wait in Mobster on your Mac. Likely to work. Checked against Arcade’s Grok Bot guide (11 Sep 2026, updated 30 Sep 2026) and xAI’s Grok Bot docs on 8 Oct 2026; not yet run by us.

The xAI API

xAI’s Responses API calls remote MCP servers itself, with a token in authorization. Use a Remote key:

curl -s https://api.x.ai/v1/responses \
  -H "Authorization: Bearer $XAI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "grok-4.7",
    "input": "Use Mobster to check what is on my calendar tomorrow.",
    "tools": [{
      "type": "mcp",
      "server_url": "https://remote.mobster.dev/mcp",
      "server_label": "mobster",
      "authorization": "'"$MOBSTER_REMOTE_KEY"'"
    }]
  }'

xAI describes authorization as “a token that will be set in the Authorization header” and doesn’t say whether it adds Bearer. Mobster takes a Remote key in the Authorization header with or without Bearer, so either works. In xAI’s own Python SDK, the mcp() helper takes the same server_url, server_label and authorization. Checked against xAI’s docs on 8 Oct 2026 (“Remote MCP tools”); not yet run by us.

The OpenAI API

The Responses API’s mcp tool calls remote MCP servers from OpenAI’s side. Put a Remote key in authorization, without Bearer:

import os
from openai import OpenAI

client = OpenAI()
response = client.responses.create(
    model="gpt-6-astra",
    tools=[{
        "type": "mcp",
        "server_label": "mobster",
        "server_url": "https://remote.mobster.dev/mcp",
        "authorization": os.environ["MOBSTER_REMOTE_KEY"],
        "require_approval": "never",
    }],
    input="Use Mobster to check what's on my calendar tomorrow.",
)
print(response.output_text)

Without "require_approval": "never", the API stops before each call to Mobster and waits for your code to approve sharing data with it. Mobster’s own approvals don’t change: a send, buy, post or delete still waits for you in Mobster on your Mac. OpenAI says it doesn’t store what you put in authorization. Checked against OpenAI’s docs on 8 Oct 2026 (“MCP and connectors”); not yet run by us.

The Anthropic API

The Messages API’s MCP connector calls remote MCP servers from Anthropic’s side. It needs the server in mcp_servers, an mcp_toolset that names it, and the mcp-client-2025-11-20 beta. Put a Remote key in authorization_token:

import os
import anthropic

client = anthropic.Anthropic()
response = client.beta.messages.create(
    model="claude-opus-5-5",
    max_tokens=16000,
    betas=["mcp-client-2025-11-20"],
    mcp_servers=[{
        "type": "url",
        "url": "https://remote.mobster.dev/mcp",
        "name": "mobster",
        "authorization_token": os.environ["MOBSTER_REMOTE_KEY"],
    }],
    tools=[{"type": "mcp_toolset", "mcp_server_name": "mobster"}],
    messages=[{"role": "user", "content": "Use Mobster to check what's on my calendar tomorrow."}],
)
for block in response.content:
    if block.type == "text":
        print(block.text)

Checked against Anthropic’s API docs on 8 Oct 2026 (the MCP connector); not yet run by us.

Other assistants

Any assistant that takes a remote MCP server URL and signs in with OAuth 2.1 (Client ID Metadata Documents or Dynamic Client Registration, with PKCE), or sends a fixed Authorization: Bearer header, can connect the same way. Mobster also recognizes Le Chat, Perplexity and Gemini by their domains. We haven’t run Mobster Remote with any of them. An assistant with no way to add an MCP server or a tool by URL can’t connect until it has one.
