Basecamp Automation via Rube MCP
Automate Basecamp operations including project management, to-do list creation, task management, message board posting, people management, and to-do group organization through Composio's Basecamp toolkit.
Prerequisites
- Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
- Active Basecamp connection via
RUBE_MANAGE_CONNECTIONS with toolkit basecamp
- 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.
- Verify Rube MCP is available by confirming
RUBE_SEARCH_TOOLS responds
- Call
RUBE_MANAGE_CONNECTIONS with toolkit basecamp
- If connection is not ACTIVE, follow the returned auth link to complete Basecamp OAuth
- Confirm connection status shows ACTIVE before running any workflows
Core Workflows
1. Manage To-Do Lists and Tasks
When to use: User wants to create to-do lists, add tasks, or organize work within a Basecamp project
Tool sequence:
BASECAMP_GET_PROJECTS - List projects to find the target bucket_id [Prerequisite]
BASECAMP_GET_BUCKETS_TODOSETS - Get the to-do set within a project [Prerequisite]
BASECAMP_GET_BUCKETS_TODOSETS_TODOLISTS - List existing to-do lists to avoid duplicates [Optional]
BASECAMP_POST_BUCKETS_TODOSETS_TODOLISTS - Create a new to-do list in a to-do set [Required for list creation]
BASECAMP_GET_BUCKETS_TODOLISTS - Get details of a specific to-do list [Optional]
BASECAMP_POST_BUCKETS_TODOLISTS_TODOS - Create a to-do item in a to-do list [Required for task creation]
BASECAMP_CREATE_TODO - Alternative tool for creating individual to-dos [Alternative]
BASECAMP_GET_BUCKETS_TODOLISTS_TODOS - List to-dos within a to-do list [Optional]
Key parameters for creating to-do lists:
bucket_id: Integer project/bucket ID (from GET_PROJECTS)
todoset_id: Integer to-do set ID (from GET_BUCKETS_TODOSETS)
name: Title of the to-do list (required)
description: HTML-formatted description (supports Rich text)
Key parameters for creating to-dos:
bucket_id: Integer project/bucket ID
todolist_id: Integer to-do list ID
content: What the to-do is for (required)
description: HTML details about the to-do
assignee_ids: Array of integer person IDs
due_on: Due date in YYYY-MM-DD format
starts_on: Start date in YYYY-MM-DD format
notify: Boolean to notify assignees (defaults to false)
completion_subscriber_ids: Person IDs notified upon completion
Pitfalls:
- A project (bucket) can contain multiple to-do sets; selecting the wrong
todoset_id creates lists in the wrong section
- Always check existing to-do lists before creating to avoid near-duplicate names
- Success payloads include user-facing URLs (
app_url, app_todos_url); prefer returning these over raw IDs
- All IDs (
bucket_id, todoset_id, todolist_id) are integers, not strings
- Descriptions support HTML formatting only, not Markdown
2. Post and Manage Messages
When to use: User wants to post messages to a project message board or update existing messages
Tool sequence:
BASECAMP_GET_PROJECTS - Find the target project and bucket_id [Prerequisite]
BASECAMP_GET_MESSAGE_BOARD - Get the message board ID for the project [Prerequisite]
BASECAMP_CREATE_MESSAGE - Create a new message on the board [Required]
BASECAMP_POST_BUCKETS_MESSAGE_BOARDS_MESSAGES - Alternative message creation tool [Fallback]
BASECAMP_GET_MESSAGE - Read a specific message by ID [Optional]
BASECAMP_PUT_BUCKETS_MESSAGES - Update an existing message [Optional]
Key parameters:
bucket_id: Integer project/bucket ID
message_board_id: Integer message board ID (from GET_MESSAGE_BOARD)
subject: Message title (required)
content: HTML body of the message
status: Set to "active" to publish immediately
category_id: Message type classification (optional)
subscriptions: Array of person IDs to notify; omit to notify all project members
Pitfalls:
status="draft" can produce HTTP 400; use status="active" as the reliable option
bucket_id and message_board_id must belong to the same project; mismatches fail or misroute
- Message content supports HTML tags only; not Markdown
- Updates via
PUT_BUCKETS_MESSAGES replace the entire body -- include the full corrected content, not just a diff
- Prefer
app_url from the response for user-facing confirmation links
- Both
CREATE_MESSAGE and POST_BUCKETS_MESSAGE_BOARDS_MESSAGES do the same thing; use CREATE_MESSAGE first and fall back to POST if it fails
3. Manage People and Access
When to use: User wants to list people, manage project access, or add new users
Tool sequence:
BASECAMP_GET_PEOPLE - List all people visible to the current user [Required]
BASECAMP_GET_PROJECTS - Find the target project [Prerequisite]
BASECAMP_LIST_PROJECT_PEOPLE - List people on a specific project [Required]
BASECAMP_GET_PROJECTS_PEOPLE - Alternative to list project members [Alternative]
BASECAMP_PUT_PROJECTS_PEOPLE_USERS - Grant or revoke project access [Required for access changes]
Key parameters for PUT_PROJECTS_PEOPLE_USERS:
project_id: Integer project ID
grant: Array of integer person IDs to add to the project
revoke: Array of integer person IDs to remove from the project
create: Array of objects with name, email_address, and optional company_name, title for new users
- At least one of
grant, revoke, or create must be provided
Pitfalls:
- Person IDs are integers; always resolve names to IDs via GET_PEOPLE first
project_id for people management is the same as bucket_id for other operations
LIST_PROJECT_PEOPLE and GET_PROJECTS_PEOPLE are near-identical; use either
- Creating users via
create also grants them project access in one step
4. Organize To-Dos with Groups
When to use: User wants to organize to-dos within a list into color-coded groups
Tool sequence:
BASECAMP_GET_PROJECTS - Find the target project [Prerequisite]
BASECAMP_GET_BUCKETS_TODOLISTS - Get the to-do list details [Prerequisite]
BASECAMP_GET_TODOLIST_GROUPS - List existing groups in a to-do list [Optional]
BASECAMP_GET_BUCKETS_TODOLISTS_GROUPS - Alternative group listing [Alternative]
BASECAMP_POST_BUCKETS_TODOLISTS_GROUPS - Create a new group in a to-do list [Required]
BASECAMP_CREATE_TODOLIST_GROUP - Alternative group creation tool [Alternative]
Key parameters:
bucket_id: Integer project/bucket ID
todolist_id: Integer to-do list ID
name: Group title (required)
color: Visual color identifier -- one of: white, red, orange, yellow, green, blue, aqua, purple, gray, pink, brown
status: Filter for listing -- "archived" or "trashed" (omit for active groups)
Pitfalls:
POST_BUCKETS_TODOLISTS_GROUPS and CREATE_TODOLIST_GROUP are near-identical; use either
- Color values must be from the fixed palette; arbitrary hex/rgb values are not supported
- Groups are sub-sections within a to-do list, not standalone entities
5. Browse and Inspect Projects
When to use: User wants to list projects, get project details, or explore project structure
Tool sequence:
BASECAMP_GET_PROJECTS - List all active projects [Required]
BASECAMP_GET_PROJECT - Get comprehensive details for a specific project [Optional]
BASECAMP_GET_PROJECTS_BY_PROJECT_ID - Alternative project detail retrieval [Alternative]
Key parameters:
status: Filter by "archived" or "trashed"; omit for active projects
project_id: Integer project ID for detailed retrieval
Pitfalls:
- Projects are sorted by most recently created first
- The response includes a
dock array with tools (todoset, message_board, etc.) and their IDs
- Use the dock tool IDs to find
todoset_id, message_board_id, etc. for downstream operations
Common Patterns
ID Resolution
Basecamp uses a hierarchical ID structure. Always resolve top-down:
- Project (bucket_id):
BASECAMP_GET_PROJECTS -- find by name, capture the id
- To-do set (todoset_id): Found in project dock or via
BASECAMP_GET_BUCKETS_TODOSETS
- Message board (message_board_id): Found in project dock or via
BASECAMP_GET_MESSAGE_BOARD
- To-do list (todolist_id):
BASECAMP_GET_BUCKETS_TODOSETS_TODOLISTS
- People (person_id):
BASECAMP_GET_PEOPLE or BASECAMP_LIST_PROJECT_PEOPLE
- Note:
bucket_id and project_id refer to the same entity in different contexts
Pagination
Basecamp uses page-based pagination on list endpoints:
- Response headers or body may indicate more pages available
GET_PROJECTS, GET_BUCKETS_TODOSETS_TODOLISTS, and list endpoints return paginated results
- Continue fetching until no more results are returned
Content Formatting
- All rich text fields use HTML, not Markdown
- Wrap content in
<div> tags; use <strong>, <em>, <ul>, <ol>, <li>, <a> etc.
- Example:
<div><strong>Important:</strong> Complete by Friday</div>
Known Pitfalls
ID Formats
- All Basecamp IDs are integers, not strings or UUIDs
bucket_id = project_id (same entity, different parameter names across tools)
- To-do set IDs, to-do list IDs, and message board IDs are found in the project's
dock array
- Person IDs are integers; resolve names via
GET_PEOPLE before operations
Status Field
status="draft" for messages can cause HTTP 400; always use status="active"
- Project/to-do list status filters:
"archived", "trashed", or omit for active
Content Format
- HTML only, never Markdown
- Updates replace the entire body, not a partial diff
- Invalid HTML tags may be silently stripped
Rate Limits
- Basecamp API has rate limits; space out rapid sequential requests
- Large projects with many to-dos should be paginated carefully
URL Handling
- Prefer
app_url from API responses for user-facing links
- Do not reconstruct Basecamp URLs manually from IDs
