Overview

AI-generated overview

Lets an assistant build and test short-form marketing automations, with no ability to publish or post anything.

What you can do
Mutator is a remote MCP server for building and testing short-form marketing automations from an agent. According to its description, it lets the assistant construct and try out automations, and nothing it does can post. No individual tools are listed in the supplied manifest.
When to use it
Consider it when you want an assistant to draft and test short-form marketing automations without giving it the ability to publish. It is less useful if you need the assistant to actually send or post content.
Requirements
A remote endpoint at mutator.app over streamable HTTP; no local package or runtime is needed. Authentication is optional: either an Authorization header with a Bearer Mutator API key from Settings, API keys, or OAuth sign-in if the header is omitted.
Before you install
The Authorization header carries a Mutator API key, so treat it as a secret. The description states nothing it does can post, but automations are still created and tested, so review what is built before relying on it.

Installation

In SourceWeft

  1. Open Mutator in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. 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/app.mutator%2Fmutator/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. The client completes OAuth sign-in on first connect.

Tools

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.
