Overview

AI-generated overview

Lets an assistant read and manage Sendlane email marketing lists, contacts, tags, custom fields, segments, campaigns and SMS reports.

What it does
A hosted remote MCP server for Sendlane. Read tools cover lists, contacts, unsubscribed contacts, subscriptions, tags, custom fields, segments, campaigns, campaign reports, SMS messages, SMS reports and sender profiles. Write tools create or update lists, add or remove contacts from lists, unsubscribe contacts, create tags, tag or untag contacts, and set contact custom fields. Meta tools report usage, request a feature, and manage a paid subscription.
When to use it
Use it when an assistant needs to look up or act on Sendlane audience data, such as checking list membership, contact tags or campaign and SMS performance, or making routine list and tagging changes. It suits teams already using Sendlane who want that data reachable from an MCP client.
Requirements
A remote MCP endpoint; no local install. Connect the client to the server URL only, with no Authorization header or API key in the config. The server signs the user in with OAuth, and the login page asks for Sendlane credentials. Network access to the endpoint is required.
Before you install
Write tools change data: creating and updating lists, adding or removing contacts, unsubscribing contacts, tagging and untagging, and setting custom fields; clients should confirm these. The login page collects Sendlane credentials, so treat them as sensitive. A free tier is limited to 100 tool calls per month, and Pro is a paid subscription billed through Stripe Checkout; cancelling gives no refund for the current period.

README

Sendlane MCP by usefulapi

Use Sendlane from Claude, Cursor, or any MCP client — lists, contacts, tags, segments, custom fields, campaign and SMS reports. Hosted, no local install: connect with your own Sendlane credentials.

Live endpoint: https://sendlane.usefulapi.io/mcp · Homepage: https://usefulapi.io/sendlane

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://sendlane.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http sendlane https://sendlane.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": {    "sendlane": {      "url": "https://sendlane.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 Sendlane credentials.
