AgentiSend

Publisher not verified

AgentiSend is a transactional email API: send through verified domains with a message log, budgets, a preflight and refusals that name the fix; built so AI agents can send on your behalf. The hosted MCP server at https://api.agentisend.com/mcp exposes 82 tools (44 on tools/list; the rest via list_more_tools). A send is one message or a batch of up to 500 items with per-item results. preflight_email runs every gate a real send runs, sends nothing, and costs nothing. Every 4xx returns code, message, and fix. There is no tool for unsolicited mail. Auth is a bearer API key or OAuth 2.1 with dynamic client registration. Starter prompts: "Send this receipt to the customer." "Preflight this send and tell me what would stop it." "What can I spend today?"

  • Glama connectors

    API result set; pagination may cap at approximately 1,000 connectors. Not exhaustive.

  • Glama source code

    Complete chronological source-code catalog response; not a list of ready-to-use endpoints.

  • Official MCP Registry

    Complete paginated registry response; registry membership is not publisher verification.

  • API Tracker · publisher documentation

    Publisher-documented presets reviewed by API Tracker. Discoverability does not establish host OAuth readiness.

Listings are grouped by exact public endpoints, exact package sets, or explicit reviewed identity bindings. Shared names or repositories alone do not merge implementations. Registry affiliation and source quality scores do not establish an official publisher.
