Verify addresses and send physical mail via Lob, from Claude, Cursor, or any MCP client. Hosted, no local install — connect with your Lob API key.
Live endpoint: https://lob.usefulapi.io/mcp · Homepage: https://usefulapi.io/lob
https://lob.usefulapi.io/mcp.claude mcp add --transport http lob https://lob.usefulapi.io/mcp, then run /mcp to log in.{
"mcpServers": { "lob": { "url": "https://lob.usefulapi.io/mcp" } } }
Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Lob credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/lob/
On first connect you'll paste your Lob API key. It's validated, stored per-user, and scoped to you.
