Overview

AI-generated overview

Hosted Robly MCP server that lets an assistant look up email-marketing contacts and lists, and subscribe, update, move or unsubscribe contacts.

What you can do
  • List, search and inspect contacts, including status, sign-up source, lists and data fields
  • Check whether a contact is on a given list, and list sub lists and contact data fields
  • Read the sign-up form configuration (available fields and lists)
  • Subscribe new contacts, add or remove contacts from lists, and update contact fields and memberships
  • Unsubscribe contacts, create sub lists and rename sub lists
  • Check usage, request a feature, upgrade or cancel the paid plan
When to use it
Useful when you work with a Robly email-marketing account and want an assistant to answer questions about subscribers and list membership, or to make routine contact changes such as subscribing someone, adding them to a newsletter list or unsubscribing them.
Requirements
A remote MCP endpoint added by URL only; the server signs in with OAuth and the login page asks for Robly credentials. On first connect you paste your Robly API ID and API Key (from My Account or Robly support). No API key or Authorization header goes in the client config. A free tier allows 50 tool calls per month; paid plans are available.
Before you install
Seven tools write to Robly data: subscribing, adding or removing list membership, updating contacts, unsubscribing, and creating or renaming lists. Unsubscribing cannot be undone through the API. Subscribe and add-to-list options can trigger Robly emails to the contact (double opt-in, welcome, autoresponders). The server asks for your Robly API ID and API Key, and paid plans involve payment links and a subscription that must be cancelled explicitly.

Installation

In SourceWeft

  1. Open Robly 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%2Frobly/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

Add this to your client's mcpServers config.

robly_subscribe_contact

Subscribe contact

WRITE: add a new subscribed contact (or re-submit an existing one through the sign-up form). With double_opt_in Robly EMAILS the contact a confirmation link first; with welcome_email it EMAILS the welcome message right away; with include_autoresponder it triggers matching autoresponders, which email the contact. Only subscribe people who agreed to receive email. Field values go in `fields`, keyed by the user_tag from robly_list_fields (for example fname, lname). POST /api/v1/sign_up/generate.

robly_update_contact

Update contact
