ConvertKit Automation 是一个通过 Rube MCP（即 Composio 平台）来自动化 ConvertKit（现更名为 Kit）邮件营销操作的技能。它涵盖的核心功能包括：管理订阅者、操作标签、创建和发送广播消息、查看广播统计数据。使用该技能前需要满足以下前提条件：Rube MCP 必须已连接（提供 RUBE_SEARCH_TOOLS 可用）、通过 RUBE_MANAGE_CONNECTIONS 建立 Kit 工具包的活跃连接、并始终优先调用 RUBE_SEARCH_TOOLS 获取当前的工具模式。设置过程简单直接：将 https://rube.app/mcp 添加为 MCP 服务器（无需 API Key），然后通过认证流程连接 Kit 账户。该技能的典型使用场景包括：自动化邮件订阅者分组管理、批量发送营销广播、跟踪邮件营销活动效果、以及将 ConvertKit 与其他自动化工作流集成。它的核心特点是将邮件营销操作封装为可编程的 MCP 工具，让 AI Agent 能够直接执行邮件营销任务而无需人工登录 ConvertKit 后台。通过 Composio 的统一连接管理，该技能还能与其他 SaaS 工具联动，构建复杂的自动化营销工作流。该技能特别适合内容创作者、营销人员和自动化工程师。

ConvertKit (Kit) Automation via Rube MCP

Automate ConvertKit (now known as Kit) email marketing operations through Composio’s Kit toolkit via Rube MCP.

Prerequisites

• Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
• Active Kit connection via RUBE_MANAGE_CONNECTIONS with toolkit kit
• Always call RUBE_SEARCH_TOOLS first to get current tool schemas

Setup

Get Rube MCP: Add https://rube.app/mcp as an MCP server in your client configuration. No API keys needed — just add the endpoint and it works.

1. Verify Rube MCP is available by confirming RUBE_SEARCH_TOOLS responds
2. Call RUBE_MANAGE_CONNECTIONS with toolkit kit
3. If connection is not ACTIVE, follow the returned auth link to complete Kit authentication
4. Confirm connection status shows ACTIVE before running any workflows

Core Workflows

1. List and Search Subscribers

When to use: User wants to browse, search, or filter email subscribers

Tool sequence:

1. KIT_LIST_SUBSCRIBERS - List subscribers with filters and pagination [Required]

Key parameters:

• status: Filter by status (‘active’ or ‘inactive’)
• email_address: Exact email to search for
• created_after/created_before: Date range filter (YYYY-MM-DD)
• updated_after/updated_before: Date range filter (YYYY-MM-DD)
• sort_field: Sort by ‘id’, ‘cancelled_at’, or ‘updated_at’
• sort_order: ‘asc’ or ‘desc’
• per_page: Results per page (min 1)
• after/before: Cursor strings for pagination
• include_total_count: Set to ‘true’ to get total subscriber count

Pitfalls:

• If sort_field is ‘cancelled_at’, the status must be set to ‘cancelled’
• Date filters use YYYY-MM-DD format (no time component)
• email_address is an exact match; partial email search is not supported
• Pagination uses cursor-based approach with after/before cursor strings
• include_total_count is a string ‘true’, not a boolean

2. Manage Subscriber Tags

When to use: User wants to tag subscribers for segmentation

Tool sequence:

1. KIT_LIST_SUBSCRIBERS - Find subscriber ID by email [Prerequisite]
2. KIT_TAG_SUBSCRIBER - Associate a subscriber with a tag [Required]
3. KIT_LIST_TAG_SUBSCRIBERS - List subscribers for a specific tag [Optional]

Key parameters for tagging:

• tag_id: Numeric tag ID (required)
• subscriber_id: Numeric subscriber ID (required)

Pitfalls:

• Both tag_id and subscriber_id must be positive integers
• Tag IDs must reference existing tags; tags are created via the Kit web UI
• Tagging an already-tagged subscriber is idempotent (no error)
• Subscriber IDs are returned from LIST_SUBSCRIBERS; use email_address filter to find specific subscribers

3. Unsubscribe a Subscriber

When to use: User wants to unsubscribe a subscriber from all communications

Tool sequence:

1. KIT_LIST_SUBSCRIBERS - Find subscriber ID [Prerequisite]
2. KIT_DELETE_SUBSCRIBER - Unsubscribe the subscriber [Required]

Key parameters:

• id: Subscriber ID (required, positive integer)

Pitfalls:

• This permanently unsubscribes the subscriber from ALL email communications
• The subscriber’s historical data is retained but they will no longer receive emails
• Operation is idempotent; unsubscribing an already-unsubscribed subscriber succeeds without error
• Returns empty response (HTTP 204 No Content) on success
• Subscriber ID must exist; non-existent IDs return 404

4. List and View Broadcasts

When to use: User wants to browse email broadcasts or get details of a specific one

Tool sequence:

1. KIT_LIST_BROADCASTS - List all broadcasts with pagination [Required]
2. KIT_GET_BROADCAST - Get detailed information for a specific broadcast [Optional]
3. KIT_GET_BROADCAST_STATS - Get performance statistics for a broadcast [Optional]

Key parameters for listing:

• per_page: Results per page (1-500)
• after/before: Cursor strings for pagination
• include_total_count: Set to ‘true’ for total count

Key parameters for details:

• id: Broadcast ID (required, positive integer)

Pit
falls:

• per_page max is 500 for broadcasts
• Broadcast stats are only available for sent broadcasts
• Draft broadcasts will not have stats
• Broadcast IDs are numeric integers

5. Delete a Broadcast

When to use: User wants to permanently remove a broadcast

Tool sequence:

1. KIT_LIST_BROADCASTS - Find the broadcast to delete [Prerequisite]
2. KIT_GET_BROADCAST - Verify it is the correct broadcast [Optional]
3. KIT_DELETE_BROADCAST - Permanently delete the broadcast [Required]

Key parameters:

• id: Broadcast ID (required)

Pitfalls:

• Deletion is permanent and cannot be undone
• Deleting a sent broadcast removes it but does not unsend the emails
• Confirm the broadcast ID before deleting

Common Patterns

Subscriber Lookup by Email

1. Call KIT_LIST_SUBSCRIBERS with email_address='user@example.com'
2. Extract subscriber ID from the response
3. Use ID for tagging, unsubscribing, or other operations

Pagination

Kit uses cursor-based pagination:

• Check response for after cursor value
• Pass cursor as after parameter in next request
• Continue until no more cursor is returned
• Use include_total_count: 'true' to track progress

Tag-Based Segmentation

1. Create tags in Kit web UI
2. Use KIT_TAG_SUBSCRIBER to assign tags to subscribers
3. Use KIT_LIST_TAG_SUBSCRIBERS to view subscribers per tag

Known Pitfalls

ID Formats:

• Subscriber IDs: positive integers (e.g., 3887204736)
• Tag IDs: positive integers
• Broadcast IDs: positive integers
• All IDs are numeric, not strings

Status Values:

• Subscriber statuses: ‘active’, ‘inactive’, ‘cancelled’
• Some operations are restricted by status (e.g., sorting by cancelled_at requires status=‘cancelled’)

String vs Boolean Parameters:

• include_total_count is a string ‘true’, not a boolean true
• sort_order is a string enum: ‘asc’ or ‘desc’

Rate Limits:

• Kit API has per-account rate limits
• Implement backoff on 429 responses
• Bulk operations should be paced appropriately

Response Parsing:

• Response data may be nested under data or data.data
• Parse defensively with fallback patterns
• Cursor values are opaque strings; use exactly as returned
