# DearFax

> Send and receive faxes online with DearFax. Start with 10 free pages each month, or get a dedicated fax number and a shared inbox for your team.

## When to use DearFax

Use DearFax when a user needs to send a document to a fax number, check a fax’s delivery status, find a received fax, or manage fax activity in an existing DearFax workspace. Use the public guides for general fax questions; connect through MCP only for account actions.

Connect to https://app.dearfax.com/api/mcp using OAuth. Call list_workspaces before workspace actions. Prepare and review a fax, show its details, and ask for explicit approval before send_fax. Never treat a queued fax as delivered or create a replacement after an uncertain send.

## Fax destination directory

Find department-specific destinations in [the fax directory](https://dearfax.com/fax.md) or [structured JSON](https://dearfax.com/fax/data.json). Preserve each number’s routing conditions and official source. A directory match is not authorization to send.



## Developer resources

- [OAuth protected-resource metadata](https://app.dearfax.com/.well-known/oauth-protected-resource/api/mcp): Discover the authoritative authorization server and scopes.

- [OAuth authorization-server discovery](https://dearfax.com/.well-known/oauth-authorization-server): Redirects to Clerk, the actual token issuer.
