## For AI assistants

3L-Group Technology exposes MCP tools over streamable HTTP (authenticated with an `X-API-Key` header):

- `draft_letter` — validate an address, screen content, return a price quote. Never sends.
- `draft_fax` — validate a fax number, screen content, return a price quote. Never sends.
- `request_send` — create a send request. On connected accounts it sends automatically inside the account's spending caps; otherwise it waits for human approval.
- `send_status` — check a send's status, cost, and billing state.

There is deliberately no direct-send tool. Every send flows through the account's approval setting and protective caps. Full reference: https://3lgrouptechnology.com/llms-full.txt
