GETTING STARTED

Copy the setup prompt

Copy the instructions on the setup page and paste them into Claude, Cursor, Windsurf, Codex CLI, or any MCP-capable client.

Set up Fastsend in this agent or harness. First read https://fastsend.dev/skill.md for the service instructions; if you cannot fetch it, continue using the hosted Streamable HTTP MCP endpoint https://fastsend.dev/mcp. Check my existing MCP setup first and preserve other servers. Configure Fastsend using this harness's supported method, or give me exact manual steps if you cannot make the change. After any required reload, list the Fastsend tools, call get_service_status, and call get_pricing for email and SMS (ask for my destination country if needed for SMS). Tell me what succeeded, the quoted prices, and any payment setup needed for a future send. Do not send messages, verify recipients, create wallets, or pay during setup. Do not say Fastsend is ready if connection or checks fail.

Let the agent read the skill file

The prompt tells your agent to read https://fastsend.dev/skill.md, which describes the service, the onboarding steps, and all five MCP tools.

Agent connects and verifies readiness

Your agent connects to the hosted MCP endpoint, lists its tools, checks service health and pricing, and reports back — without sending messages or making payments during setup.

MCP endpoint (Streamable HTTP):
https://fastsend.dev/mcp

Start sending messages

Once your agent confirms it is ready, ask it to send an SMS or email using Fastsend.

User: Send an email to [email protected], name them "Taylor", use subject "Welcome to Fastsend", and say "Your account is ready."

AI: I'll send that email for you using Fastsend.

[Uses send_message tool]
