LinkedIn Automation via Rube MCP
Automate LinkedIn operations through Composio's LinkedIn toolkit via Rube MCP.
Prerequisites
Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
Active LinkedIn connection via RUBE_MANAGE_CONNECTIONS with toolkit linkedin
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 linkedin
If connection is not ACTIVE, follow the returned auth link to complete LinkedIn OAuth
Confirm connection status shows ACTIVE before running any workflows
Core Workflows
1. Create a LinkedIn Post When to use : User wants to publish a text post on LinkedIn
LINKEDIN_GET_MY_INFO - Get authenticated user's profile info [Prerequisite]
LINKEDIN_REGISTER_IMAGE_UPLOAD - Register image upload if post includes an image [Optional]
LINKEDIN_CREATE_LINKED_IN_POST - Publish the post [Required]
text: Post content text
visibility: 'PUBLIC' or 'CONNECTIONS'
media_title: Title for attached media
media_description: Description for attached media
Must retrieve user profile URN via GET_MY_INFO before creating a post
Image uploads require a two-step process: register upload first, then include the asset in the post
Post text has character limits enforced by LinkedIn API
Visibility defaults may vary; always specify explicitly
2. Get Profile Information When to use : User wants to retrieve their LinkedIn profile or company details
LINKEDIN_GET_MY_INFO - Get authenticated user's profile [Required]
LINKEDIN_GET_COMPANY_INFO - Get company page details [Optional]
No parameters needed for GET_MY_INFO (uses authenticated user)
organization_id: Company/organization ID for GET_COMPANY_INFO
GET_MY_INFO returns the authenticated user only; cannot look up other users
Company info requires the numeric organization ID, not the company name or vanity URL
Some profile fields may be restricted based on OAuth scopes granted
3. Manage Post Images When to use : User wants to upload and attach images to LinkedIn posts
LINKEDIN_REGISTER_IMAGE_UPLOAD - Register an image upload with LinkedIn [Required]
Upload the image binary to the returned upload URL [Required]
LINKEDIN_GET_IMAGES - Verify uploaded image status [Optional]
LINKEDIN_CREATE_LINKED_IN_POST - Create post with the image asset [Required]
owner: URN of the image owner (user or organization)
image_id: ID of the uploaded image for GET_IMAGES
The upload is a two-phase process: register then upload binary
Image asset URN from registration must be used when creating the post
Supported formats typically include JPG, PNG, and GIF
Large images may take time to process before they are available
4. Comment on Posts When to use : User wants to comment on an existing LinkedIn post
LINKEDIN_CREATE_COMMENT_ON_POST - Add a comment to a post [Required]
post_id: The URN or ID of the post to comment on
text: Comment content
actor: URN of the commenter (user or organization)
Post ID must be a valid LinkedIn URN format
The actor URN must match the authenticated user or a managed organization
Rate limits apply to comment creation; avoid rapid-fire comments
5. Delete a Post When to use : User wants to remove a previously published LinkedIn post
LINKEDIN_DELETE_LINKED_IN_POST - Delete the specified post [Required]
post_id: The URN or ID of the post to delete
Deletion is permanent and cannot be undone
Only the post author or organization admin can delete a post
The post_id must be the exact URN returned when the post was created
Common Patterns
ID Resolution 1. Call LINKEDIN_GET_MY_INFO
2. Extract user URN (e.g., 'urn:li:person:XXXXXXXXXX')
3. Use URN as actor/owner in subsequent calls
Organization ID from company :
1. Call LINKEDIN_GET_COMPANY_INFO with organization_id
2. Extract organization URN for posting as a company page
Image Upload Flow
Call REGISTER_IMAGE_UPLOAD to get upload URL and asset URN
Upload the binary image to the provided URL
Use the asset URN when creating a post with media
Verify with GET_IMAGES if upload status is uncertain
Known Pitfalls
LinkedIn OAuth tokens have limited scopes; ensure required permissions are granted
Tokens expire; re-authenticate if API calls return 401 errors
LinkedIn uses URN identifiers (e.g., 'urn:li:person:ABC123')
Always use the full URN format, not just the alphanumeric ID portion
Organization URNs differ from person URNs
LinkedIn API has strict daily rate limits on post creation and comments
Implement backoff strategies for bulk operations
Monitor 429 responses and respect Retry-After headers
Posts have character limits enforced by the API
Some content types (polls, documents) may require additional API features
HTML markup in post text is not supported
