Using Paxton in Claude (MCP)
Connect your Paxton account to Claude and run legal research with verifiable citations, without leaving the conversation.
The Paxton connector gives Claude direct access to U.S. statutes, regulations, court rules, case law, and indexed agency decisions, and returns citations you can open and verify in Paxton.
Included with your subscription. If you already have Paxton legal research access, the MCP connector is included at no separate fee and uses your existing account and organization access.

Before you start
An active Paxton account with legal research access. New to Paxton? Create an account at app.paxton.ai/sign-up, then connect once legal research is enabled on your account.
A Claude account. The connector works in Claude on web, desktop, and mobile.
Note for firms on Claude Team or Enterprise. A Claude workspace administrator may need to enable the Paxton connector before it appears for your users. If you do not see it, ask your workspace admin to approve it first.
Connect Paxton to Claude
In Claude, open Settings > Connectors and select the Discover tab.
Find Paxton Legal Research and click Connect to Claude. You can also start from the Paxton Legal Research connector page.
Sign in with your Paxton credentials when prompted, then approve access.
Paxton now appears under Your connectors, and in the connector list in a new Claude chat when you click the + button next to the message box.
The Paxton Legal Research connector under Settings > Connectors > Discover in Claude.
If your admin has asked you to add the connector manually, open Settings > Connectors > Add custom connector in Claude and enter the connector URL:
Run your first research question
In a new Claude chat, click the + button next to the message box, hover over Connectors, and make sure Paxton is toggled on. Name the jurisdiction and be specific about the issue. The first time Claude uses Paxton, you'll be asked to approve it. Click Allow.
"Using Paxton, find Seventh Circuit authority on whether a failure to accommodate claim requires an adverse employment action. Give me the supporting passages."
"Search EEOC decisions on constructive discharge in retaliation cases and summarize how the Commission has analyzed the issue."
"Pull the full text of the statute you cited and check its citator status."
Claude will show you which Paxton tool it used and return the authorities with links. Follow the citations and read the source before you rely on anything.

Change anything in your Paxton account
The connector is read only. For matter-centric work such as drafting against your case record, syncing your DMS, or building a timeline, keep working in the Paxton platform.
Legal research requires professional review. Search results and citation relationships do not establish that an authority is controlling, current, or sufficient for a legal proposition. Always read the source and apply your own judgment.
Troubleshooting
Paxton does not appear in the connector list. Confirm the connection completed under Settings > Connectors in Claude. On Claude Team or Enterprise, confirm your workspace admin has enabled the connector.
You are asked to sign in repeatedly. Disconnect Paxton under Settings > Connectors, then reconnect and complete the sign-in in the same browser where you are signed in to Paxton.
Claude answers without using Paxton. In a new Claude chat, click the + button next to the message box, hover over Connectors, and make sure Paxton is toggled on. Say "using Paxton" in your prompt so Claude calls the connector instead of answering from its own knowledge.
A narrow source is not returned. The connector searches legal sources only. If the authority you need does not come back, search for it in the Paxton platform, where you can request sources on demand.
Data and security
The connector uses your existing Paxton account and organization access, so you see only what you are already entitled to see in Paxton. It cannot reach your matters or private files, and it cannot change anything in your account. Your documents and data are never used to train Paxton AI.
