A remote MCP server that gives Claude read-only access to Visalaw AI’s immigration law research tools: the Visalaw AI immigration library, case law search, statute and regulation lookup, and Visalaw AI prompt templates.

Server URL

https://mcp.visalaw.ai/mcp

Transport

Streamable HTTP (JSON-RPC 2.0 over a single POST /mcp)

Auth

OAuth 2.1 with PKCE (S256). See Authentication below.

Access

Read-only. No tool creates, modifies, or deletes data.

Requirements

A Visalaw AI account that belongs to an organization with the Visalaw AI connector enabled. Visalaw enables access per organization. Users whose organization isn’t enabled, or who have no organization membership, can’t complete sign-in.
A Claude plan that supports connectors. On Claude Team or Enterprise, an Owner adds the connector for the organization.

Adding the connector in Claude

In Claude, go to Customize → Connectors. Find Visalaw AI in the Connectors Directory, or choose Add custom connector and enter https://mcp.visalaw.ai/mcp as the server URL. On Claude Team or Enterprise, an Owner adds it under Organization settings → Connectors.
Click Connect. A Visalaw AI sign-in page opens.
Sign in with your Visalaw AI account. Visalaw AI doesn’t use passwords; sign in with Google or Microsoft 365, or with a verification code sent by email or text. See Getting Started: Logging In.
Approve access. Claude receives a scoped access token (mcp:law-library:read) and the tools below become available in your conversations.

Each connection is tied to one Visalaw AI user and organization. The connector returns only what that user can already access in Visalaw AI.

Tools

Tool	What it does
`search_immigration_library`	Semantic search over the Visalaw AI immigration library: USCIS guidance including the USCIS Policy Manual, AILA publications and practice advisories, BIA and AAO decisions, EOIR materials, the INA, the CFR, and Canadian immigration law. Results are ranked by authority, so statutes and USCIS policy come before secondary sources, and cited authorities are checked against the library catalog. Can be limited to one source or category, and can include unpublished BIA decisions.
`list_categories`	Lists the library’s practice-area categories and subcategories, such as employment-based, family-based, and removal defense. Use a category to narrow a library search.
`get_document`	Reads a library document returned by `search_immigration_library`, up to 10 pages per call. Reads only the shared law library, never a firm’s own uploaded documents.
`search_case_law`	Searches published and unpublished BIA decisions, AAO decisions, unpublished EOIR decisions, and federal court immigration opinions. Recognizes case-name lookups such as “Matter of A-B-” as well as topic searches. Defaults to the BIA and all federal circuits, and can filter by court and filing date. Federal court opinions come from CourtListener.
`lookup_statute_regulation`	Returns the text of a specific INA section or CFR provision by citation, such as “INA 245(i)” or “8 CFR 204.5(h)(3).”
`list_prompts`	Lists prompt templates available to the signed-in user: templates they own, templates shared with them, organization-wide templates, and, on request, Visalaw AI platform templates.
`get_prompt`	Returns the full text of one prompt template so Claude can apply it to the user’s task, such as analyzing an uploaded RFE. A template the user can’t see in Visalaw AI can’t be retrieved.

All seven tools are read-only. None of them modify Visalaw AI data.

Example prompts

Research an immigration question

My client entered on a B-2, married a U.S. citizen, and overstayed by eight months. Can she adjust status without leaving the U.S.? Cite the Policy Manual and any relevant BIA decisions.

Find BIA decisions on a fact pattern

Search published and unpublished BIA decisions from 2023 onward. My client missed her master calendar hearing because she was hospitalized and was ordered removed in absentia. Has the Board found exceptional circumstances in similar cases, and what evidence made the difference?

Look up the text of the law

Pull the text of INA 212(a)(9)(B).

Analyze an RFE with a Visalaw AI template

Upload an RFE to Claude, then ask:

Use the Visalaw AI RFE analysis prompt for O-1 petitions to analyze this RFE, suggest evidence for each item, flag weaknesses in the officer’s reasoning, and draft a response.

Authentication

The server implements the OAuth 2.1 discovery flow described in the MCP authorization spec:

Claude calls GET /.well-known/oauth-protected-resource/mcp to learn the authorization server.
Claude calls GET /.well-known/oauth-authorization-server to discover the /oauth/authorize and /oauth/token endpoints.
The user is redirected to /oauth/authorize (PKCE, S256 only) and signs in with their Visalaw AI account.
Claude exchanges the resulting authorization code for a Bearer access token at /oauth/token.
Claude sends the Bearer token in the Authorization header on every POST /mcp call.

Tokens are scoped to mcp:law-library:read and expire after 90 days. Refresh tokens aren’t issued; when a token expires, the user signs in again. Only registered MCP clients with exact redirect URIs are accepted. If a user’s account is removed or their organization turns the connector off, access ends immediately.

Data handling

What’s searched. The library, case law, and statute tools search Visalaw AI’s shared corpus of legal materials. They never read a firm’s uploaded client documents, chats, or drafts.
Documents you upload to Claude stay in Claude. When you ask Claude to apply a Visalaw AI template to a document such as an RFE, only the template text comes from Visalaw AI. The document itself is not sent to Visalaw AI.
Logging. For each tool call, Visalaw AI logs the tool name, user ID, and organization ID for security and abuse monitoring. Search queries, citations, and document IDs are not logged. Logs are kept for 30 days.
No training. Queries and results are not used to train models.
Third-party processing. To answer a query, search text may be processed by the services that power Visalaw AI search: an embedding and query-classification model provider, a vector search database, CourtListener for federal case law, and a statutes and regulations provider. No Visalaw AI account information is sent to CourtListener or the statutes provider.

Disconnecting

To stop using the connector, go to Customize → Connectors in Claude and disconnect Visalaw AI. To have Visalaw AI revoke your access token on its side, contact support@visalaw.ai.
