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.

## Before you connect

The MCP server is part of **Sequence Labs** and is off by default. An admin needs to switch it on in your Sequence dashboard before the connector will authenticate from Claude.

<Steps>
  <Step title="Open Labs">
    Go to [Settings > Labs](https://dashboard.sequencehq.com/settings/labs) in your Sequence dashboard.
  </Step>

  <Step title="Enable Sequence Labs">
    Toggle on **Enable Sequence Labs** to opt in to early-access features.
  </Step>

  <Step title="Enable the MCP server">
    Under **MCP server**, toggle it on. If you also want the [AR agent](/agents/ar-agent), toggle on **Enable AR agent** as well.
  </Step>
</Steps>

<Warning>
  If **Enable Sequence Labs** and the **MCP server** aren't both switched on in [Settings > Labs](https://dashboard.sequencehq.com/settings/labs), the connector won't authenticate, even after you add it in Claude.
</Warning>

## Connect Sequence to Claude

<Steps>
  <Step title="Open Connectors in Claude">
    Go to **Settings → Connectors** in Claude.
  </Step>

  <Step title="Find Sequence">
    Browse or search the connectors for **Sequence**.
  </Step>

  <Step title="Connect">
    Add Sequence and authenticate with your Sequence account when prompted.
  </Step>

  <Step title="Start querying your data">
    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>
