Runs npx -y kit-mcp-server on your machine. Read the scan report first; the gateway never runs local packages.

MCP Kit Server

<!-- -->

An MCP (Model Context Protocol) server that connects AI assistants like Claude to the Kit.com (formerly ConvertKit) email marketing platform. Manage your email lists, subscribers, broadcasts, sequences, and more through natural language.

[!WARNING]

This project is deprecated and no longer maintained. Kit now ships official, first-party MCP servers that supersede it with broader API coverage and managed authentication. Please migrate — see below.

⚠️ Deprecated — use Kit's official MCP servers

This community server was built before Kit offered its own MCP. Kit now maintains official servers that cover far more of the Kit API v4 surface (including analytics, commerce, segments, and bulk operations), handle auth for you, and stay current with API changes. New and existing users should migrate.

Migrate in Claude Code

# Remove this deprecated server (if you added it as "kit")
claude mcp remove kit

# Add the official operational Kit MCP
claude mcp add --transport http kit https://app.kit.com/mcp

# Optional: add Kit's developer-docs MCP for building integrations
claude mcp add --transport http kit-docs https://developers.kit.com/mcp
