Sequence's MCP server exposes your Sequence data to AI clients like Claude as a set of tools. Each tool wraps an existing Sequence API endpoint, authenticated via OAuth 2.0, so an assistant can fetch and reason over your billing data in response to a prompt, rather than you clicking through the dashboard.

## What it can do

Coverage maps to the objects you already work with: customers, invoices, credit notes, billing schedules, products, quotes, usage, taxes, collections, account, activity stream, and notifications, plus reporting tools like invoiced revenue and outstanding invoices.

So you can ask things in plain language and have the assistant pull and paginate through the data for you:

* "Get me all of my end-customers."
* "What's my outstanding invoice total?"
* "Show me this customer's billing schedule."

<Warning>
  The MCP server is **read-only** as it stands. Today it's about querying and surfacing your data, not changing it.
</Warning>

### What's coming

* **Write capabilities**: the first write use cases (such as agent-driven customer record changes) are in design, and will ship with human review in front of any write.
* **Marketplace certification**: we're submitting to Anthropic to be listed as an official connector for one-click setup. In the meantime it's going out to a few select customers first.

## Connect Sequence to Claude

You'll need your Sequence MCP server URL, which you can find in the Sequence dashboard.

<Steps>
  <Step title="Open Connectors in Claude">
    Go to **Settings → Connectors** in Claude and choose **Add custom connector**.
  </Step>

  <Step title="Create the custom connector">
    Paste in your Sequence MCP server URL (available in the Sequence dashboard) and authenticate with your Sequence account when prompted.
  </Step>

  <Step title="Start querying your data">
    Once connected, just ask Claude about your Sequence data in plain language. For example, "list my customers with outstanding invoices", and it'll pull it through the MCP.
  </Step>
</Steps>

<Tip>
  Connector labels and menu paths in the Claude UI may change over time. If the steps above don't match what you see, look for the equivalent "custom connector" option in Claude's settings.
