Overview

AI-generated overview

Read Sarbacane campaigns, statistics, contact lists and blacklists, and manage contacts and draft email campaigns from an assistant.

What you can do
  • Check account credits, users and webhook subscriptions
  • List contact lists, their custom fields and contacts, with filters by email, phone, text or modification date
  • Add or upsert contacts in a list
  • List blacklists and their bounces, unsubscribers and complaints; record an unsubscriber
  • List campaigns, get campaign details, per-send statistics and recipients
  • Create a draft email campaign, set or import its content and attach a contact list
When to use it
Useful when you work with a Sarbacane email/SMS marketing account and want an assistant to look up campaign performance, credits or contact data, or to prepare draft campaigns and contact updates without opening the Sarbacane interface.
Requirements
A remote MCP endpoint added by URL only; sign-in happens through OAuth, and the login page asks for your Sarbacane credentials. No API key or Authorization header goes in the client config. A usefulapi.io plan applies: free tier of 50 tool calls per month, or a paid Pro/Pro+ subscription.
Before you install
Write tools change Sarbacane data: contacts are added or overwritten, unsubscribers cannot be undone with these tools, and campaign content is replaced. Campaigns are only created as drafts and are not sent by these tools. Contact, recipient and blacklist data is personal data sent to the hosted service. Meta tools can start a paid Stripe checkout or cancel a subscription; the free tier is limited to 50 calls a month.

Installation

In SourceWeft

  1. Open Sarbacane 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%2Fsarbacane/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

Other MCP clients

Add this to your client's mcpServers config.
