MCP server

Give Claude, Cursor, VS Code and other AI assistants Attorly's tools for contracts, clauses, redlines, legal research and due diligence.

Connect your client

Each guide takes a few minutes. Create a key, paste one configuration, and ask your assistant something.

How it works

Streamable HTTP transport
The server speaks JSON-RPC 2.0 over HTTPS at one URL. Clients that only run local servers, such as Claude Desktop, connect through the mcp-remote bridge.
API keys
Every request carries a key as a Bearer token. Keys start with lbmcp_ and are created in Settings › Developers.
One key, two interfaces
The same key works for the REST API. Both share permissions, rate limits and AI credits, and every call appears in your request log.
Plans
The MCP server is included in Pro and Enterprise. Calls that run AI draw on the key owner's AI credits, as in the app.
Request header
Authorization: Bearer lbmcp_your_api_key

Tools

Every tool the server offers, as your client lists it. Descriptions are in English, the language the models read.

    Permissions:DOCUMENTS_ANALYZE· 10 calls per minute

    Permissions:DOCUMENTS_READ· 100 calls per minute
  • documents_listList documentsRead only

Troubleshooting

The client says 401 Unauthorized.
The key is missing, mistyped, revoked or expired. Check that the header reads Authorization: Bearer followed by the whole key, with no quotes or spaces. If in doubt, roll the key in Settings › Developers and paste the new setup.
A tool fails with insufficient_scope.
The key lacks a permission that tool needs. Create a key with the Standard or Full access preset, or a custom one with that permission.
Calls fail with rate_limited.
Each tool allows a set number of calls per minute per key. Wait the number of seconds the error gives, then try again.
The client shows fewer tools than this page.
Tools the key has no permission for are not listed. Restart the client after changing the key so it fetches the tool list again.
Claude Desktop shows the server as failed.
mcp-remote needs Node.js 18 or later. Install it from nodejs.org, then quit and reopen Claude Desktop. The log is in Claude Desktop under Settings › Developer.

The protocol, by hand

For building your own client or checking a key from the terminal: the three calls every client makes.

1. Start a session
curl -X POST https://attorly.ai/api/mcp \
  -H "Authorization: Bearer lbmcp_your_api_key" \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-06-18","capabilities":{},"clientInfo":{"name":"my-agent","version":"1.0.0"}}}'
2. List the tools the key may use
curl -X POST https://attorly.ai/api/mcp \
  -H "Authorization: Bearer lbmcp_your_api_key" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/list"}'
3. Call a tool
curl -X POST https://attorly.ai/api/mcp \
  -H "Authorization: Bearer lbmcp_your_api_key" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":3,"method":"tools/call","params":{"name":"documents_list","arguments":{"limit":5}}}'
