Connect an AI assistant
Connect Claude or another AI assistant to your CircuitHub account.
CircuitHub's MCP server lets an AI assistant work with your CircuitHub account: look up projects, BOMs, quotes and orders, fix BOM lines and board settings, request quotes and raise issues. The assistant acts as you, with the access you choose when you connect it. Its address is:
https://mcp.circuithub.com/mcpAny assistant that supports remote MCP servers with OAuth sign-in can connect. To script CircuitHub yourself instead, use the CLI or the API.
Claude Code
claude mcp add --transport http circuithub https://mcp.circuithub.com/mcpThen run /mcp in Claude Code, choose circuithub, then Authenticate.
Claude
In claude.ai or the Claude apps, open Customize → Connectors, choose Add, then Add custom connector. Enter https://mcp.circuithub.com/mcp, choose Add, then choose Connect on the new connector.
On Team and Enterprise plans, an owner first adds the connector under Organization settings → Connectors. Members then find it under Customize → Connectors and choose Connect.
ChatGPT
Support for ChatGPT is coming soon.
Other assistants
Add a remote (HTTP) MCP server with the address above. The assistant finds CircuitHub's sign-in by itself, so there is no client ID or key to enter.
Signing in
When you connect, the assistant opens CircuitHub in your browser. Sign in if you aren't already, and you see one confirmation page, such as "Claude wants to connect to your CircuitHub account". Choose what the assistant can do, then choose Connect, and go back to the assistant.
If the assistant runs on your computer, or CircuitHub can't verify who made it, the page shows a warning. Only connect if you started connecting it yourself, just now. If you leave the page open for more than 10 minutes, it asks you to check your choice and connect again.
Access levels
| Level | What the assistant can do |
|---|---|
| Read only | See your projects, BOMs, quotes, orders, addresses and billing. |
| Engineering (recommended) | Also edit BOMs and board settings, request quotes and raise issues. |
| Full access | Also change shipping addresses, billing details and saved cards. |
Engineering (recommended) is preselected when you connect. CircuitHub's API enforces the level you choose, whichever assistant you use, and the assistant is only offered the tools its level allows. Tools lists them with the level each needs. Assistants can't place orders: they give you a checkout link to review and pay for the order yourself. Adding a card also happens in CircuitHub, from a link the assistant gives you.
Changing access or disconnecting
Every assistant you have connected is listed under Settings → Connected apps on app.circuithub.com. There you can change what each one can do, or disconnect it.
Giving less access applies from the assistant's next request. Giving more asks you to confirm first. Most assistants only show the new tools in a new chat or after you reconnect them.
A connection unused for 90 days ends by itself. You can keep up to 20 connections at a time; connecting a 21st disconnects the one you used least recently. When a connection ends, the assistant asks you to sign in again.
Staying safe
The assistant acts as you. Anything it does is done in your name, as if you had done it in CircuitHub.
Assistants usually ask before using a tool that makes changes, but that is up to the assistant and its settings, not CircuitHub. Choose the lowest access level that does the job.
Only connect an assistant if you started connecting it yourself. If someone sends you a link that opens CircuitHub's confirmation page, cancel it. If you see a connection in Connected apps that you don't recognise, disconnect it.
