Overview

AI-generated overview

Read-only access to SendPost email delivery data: sub-accounts, sending IPs and pools, delivery statistics, message metadata, domains and suppressions.

What you can do
  • List and inspect sub-accounts, sending IPs and IP pools with warmup and routing metadata
  • Read daily and aggregate delivery, bounce, open, click, unsubscribe and spam statistics across accounts, groups and sub-accounts
  • Inspect submitted message metadata such as sender, recipient, subject and routing
  • Audit sending domains, DNS records and verification status
  • Review suppressed recipients and their documented reasons
  • Check usage status, request a missing feature, or manage the Pro subscription
When to use it
Useful when you want an assistant to answer questions about SendPost deliverability — comparing bounce or open rates across sub-accounts, spotting IPs still warming up, or checking why a domain is not verified — without opening the SendPost dashboard.
Requirements
Remote MCP endpoint added by URL only; sign-in is via OAuth with your SendPost credentials, so no API key or Authorization header goes in the client config. A SendPost account or sub-account API key is needed for the matching read-only tools, and SendPost access is purchased separately. Free plan allows 50 tool calls per month.
Before you install
The free tier is capped at 50 tool calls a month; paid plans cost $9/month or $90/year (Pro) and $39/month or $390/year (Pro+), and the upgrade tool returns a Stripe Checkout link, so a subscription can be started from the chat. Cancellation runs to the end of the paid period with no refund. The server signs you in with your SendPost credentials via OAuth; do not paste API keys into the client config. Data reads go to a third-party host.

Installation

In SourceWeft

  1. Open SendPost MCP by usefulapi in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.usefulapi%2Fsendpost/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://sendpost.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http sendpost https://sendpost.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
json
{  "mcpServers": {    "sendpost": {      "url": "https://sendpost.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 SendPost credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/sendpost/

Connect with a SendPost account or sub-account API key for the matching read-only tools. SendPost access is purchased separately.
