A remote MCP server that gives Claude read-only access to Visalaw.ai's immigration law research tools and prompt library.

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. See Authentication below.

Adding the connector in Claude

In Claude, add a custom connector (or find "Visalaw.ai" in the Connectors Directory once published) and enter https://mcp.visalaw.ai/mcp as the server URL.
You'll be redirected to sign in with your Visalaw.ai account.
After sign-in, Claude receives a scoped access token (mcp:law-library:read) and the tools below become available in your conversation.

Every connection is tied to a Visalaw.ai user and organization — the connector only returns data the signed-in user's org already has access to in the app.

Tools

Tool	What it does
`list_categories`	Lists the top-level categories/subcategories in the immigration law library. Call this first if you want to scope a search to one category.
`search_immigration_library`	Semantic search over the immigration law library (USCIS guidance, BIA/AAO decisions, INA, CFR, EOIR materials, practice advisories). Results are authority-ranked and cited authorities are checked against the library catalog. Omit `categoryId` to search the whole library.
`lookup_statute_regulation`	Direct lookup of a specific INA section or CFR provision by citation (e.g. "INA 245(i)"), bypassing semantic search.
`search_case_law`	Searches BIA decisions, AAO decisions, and federal court immigration opinions via CourtListener. Defaults to BIA + all federal circuits; state courts excluded unless explicitly requested.
`get_document`	Fetches the full text of a library document by the `documentId` returned from `search_immigration_library`.
`list_prompts`	Lists prompts saved in the signed-in user's organization prompt library (name, description, mode, tags).
`get_prompt`	Retrieves the full content of a specific saved prompt by ID, for use as a system instruction.

All seven tools are read-only — none of them modify Visalaw.ai data.

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) and signs in with their Visalaw.ai account.
Claude exchanges the resulting authorization code for a Bearer access token at /oauth/token.
Claude sends that Bearer token on every POST /mcp call. Tokens are scoped to mcp:law-library:read and expire after 90 days.
