Claude Connectors on Mobile: What Carries Across Devices
Not all Claude connectors available on desktop work on mobile. Here is how to check which connections carry across devices, why local tools do not transfer, and how to keep work context accessible when you switch between phone and desktop.
Updated 5 min read
Claude connectors on mobile work differently from those on desktop. Remote connectors that authenticate over the network can follow you to your phone. Local tool connections (MCP servers running on your laptop, local file access, local databases) cannot, because the phone has no access to your desktop machine's processes.
Tools like fenbs keep work context accessible across devices because they run remotely: any Claude client that connects to fenbs over MCP reads the same project record, whether on a phone or a desktop.
Remote connectors vs local connectors
A remote connector connects Claude to a service that runs on its own server: a project management tool, a document store, a web search API, or a shared knowledge base. These connectors are accessed over the network and work from any device that can reach them, including your phone.
A local connector runs as a process on the machine where Claude Desktop is installed. It might give Claude access to your local file system, a local database, or a tool that only runs on that machine. Local connectors do not cross device boundaries. The phone cannot reach a process running on your laptop.
The distinction matters most when you plan a workflow that spans devices. A remote connector to your project tool, your calendar or a web search service travels with you. A local connector to your code editor or your machine's filesystem does not.
What the Claude mobile app supports
The Claude mobile app (available for iOS and Android) supports native connectors that are built into the app or authorized through Claude.ai. These include integrations available from within the Claude interface, such as web search and document connections that are part of the Claude.ai feature set.
Custom MCP servers that you add through the Claude Desktop config file do not automatically appear in the mobile app. Those connections are specific to the desktop installation. If you need the same tool access on mobile, the tool must be hosted remotely and accessible over HTTPS.
Most useful connectors for mobile work
Project and task management connectors are well suited to mobile: you can read Where we left off, add a task, record a decision or check the status of ongoing work without needing access to your development machine. These are exactly the actions that benefit from being available on a phone during a commute, a meeting or a quick break.
Web search connectors are also useful on mobile, letting you do research in a Claude session without switching to a browser. Document connectors that access cloud storage (Google Drive, Dropbox) work on mobile provided the OAuth access is still valid.
Code-execution, local-file and database connectors are desktop-only for most people. Reserve those for your laptop session and use the mobile session to review context, make decisions and record notes. This division of responsibility makes mobile sessions productive without requiring feature parity with the desktop.
When evaluating whether a connector is worth setting up on mobile, ask: will I use it when I am away from my desk? A project-status connector you check during a commute earns its setup time. A connector you would only use while writing code at a full keyboard probably does not.
Checking connector availability before you rely on it
Before building a workflow that depends on a connector being available on mobile, test it on the phone first. Open the Claude mobile app, start a session and try to use the connector. A connector that works in Claude Desktop may not appear at all in the mobile app.
Check the connector's own documentation for mobile compatibility. Some MCP servers designed for desktop use have no mobile equivalent. Official integrations available from within Claude.ai are more likely to be available across devices than custom local servers.
Keeping context across devices without full connector parity
The most reliable cross-device continuity comes from keeping work context in a remote tool rather than relying on local connections to be consistent. If the project record, decisions and current tasks live in a remote-accessible tool, a quick phone session can read the same state as a full desktop session, even without the local tool connections.
Use the phone for reading context, drafting responses, making decisions and recording quick notes. Use the desktop for work that requires local tool access. The shared record carries the progress between them.
One project record across every device
fenbs is a remote MCP server, so any supported client that can reach it over the network connects to the same project record. Open a session on your phone, read Where we left off, add a quick decision and save progress. Your desktop session picks up exactly where that left off. The device you use does not determine the context you have access to.

How to do this with fenbs
- Create a free account and set up your project in fenbs.
- Connect Claude from Integrations on your desktop. Check which connectors are available there and which are local only.
- For mobile use, identify which connectors are remote and can follow you across devices.
- Use fenbs as the cross-device context layer. Ask the mobile Claude session to read the project context before starting work, and to save progress before stopping.
- Record any decisions made on mobile in fenbs so the desktop session sees them when you return.
fenbs does not install connectors on your phone or manage mobile app configuration. It provides the remote project context that any connected client can read.
