Posthog Automation

PostHog Automation via Rube MCP

Automate PostHog product analytics and feature flag management through Composio's PostHog toolkit via Rube MCP.

Prerequisites

• Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
• Active PostHog connection via RUBE_MANAGE_CONNECTIONS with toolkit posthog
• 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 posthog
3. If connection is not ACTIVE, follow the returned auth link to complete PostHog authentication
4. Confirm connection status shows ACTIVE before running any workflows

Core Workflows

1. Capture Events

When to use: User wants to send event data to PostHog for analytics tracking

Tool sequence:

1. POSTHOG_CAPTURE_EVENT - Send one or more events to PostHog [Required]

Key parameters:

• event: Event name (e.g., '$pageview', 'user_signed_up', 'purchase_completed')
• distinct_id: Unique user identifier (required)
• properties: Object with event-specific properties
• timestamp: ISO 8601 timestamp (optional; defaults to server time)

Pitfalls:

• distinct_id is required for every event; identifies the user/device
• PostHog system events use $ prefix (e.g., '$pageview', '$identify')
• Custom events should NOT use the $ prefix
• Properties are freeform; maintain consistent schemas across events
• Events are processed asynchronously; ingestion delay is typically seconds

2. List and Filter Events

When to use: User wants to browse or search through captured events

Tool sequence:

1. POSTHOG_LIST_AND_FILTER_PROJECT_EVENTS - Query events with filters [Required]

Key parameters:

• project_id: PostHog project ID (required)
• event: Filter by event name
• person_id: Filter by person ID
• after: Events after this ISO 8601 timestamp
• before: Events before this ISO 8601 timestamp
• limit: Maximum events to return
• offset: Pagination offset

Pitfalls:

• project_id is required; resolve via LIST_PROJECTS first
• Date filters use ISO 8601 format (e.g., '2024-01-15T00:00:00Z')
• Large event volumes require pagination; use offset and limit
• Results are returned in reverse chronological order by default
• Event properties are nested; parse carefully

3. Manage Feature Flags

When to use: User wants to create, view, or manage feature flags

Tool sequence:

1. POSTHOG_LIST_AND_MANAGE_PROJECT_FEATURE_FLAGS - List existing feature flags [Required]
2. POSTHOG_RETRIEVE_FEATURE_FLAG_DETAILS - Get detailed flag configuration [Optional]
3. POSTHOG_CREATE_FEATURE_FLAGS_FOR_PROJECT - Create a new feature flag [Optional]

Key parameters:

• For listing: project_id (required)
• For details: project_id, id (feature flag ID)
• For creation:
  • project_id: Target project
  • key: Flag key (e.g., 'new-dashboard-beta')
  • name: Human-readable name
  • filters: Targeting rules and rollout percentage
  • active: Whether the flag is enabled

Pitfalls:

• Feature flag key must be unique within a project
• Flag keys should use kebab-case (e.g., 'my-feature-flag')
• filters define targeting groups with properties and rollout percentages
• Creating a flag with active: true immediately enables it for matching users
• Flag changes take effect within seconds due to PostHog's polling mechanism

4. Manage Projects

When to use: User wants to list or inspect PostHog projects and organizations

Tool sequence:

1. POSTHOG_LIST_PROJECTS_IN_ORGANIZATION_WITH_PAGINATION - List all projects [Required]

Key parameters:

• organization_id: Organization identifier (may be optional depending on auth)
• limit: Number of results per page
• offset: Pagination offset

Pitfalls:

• Project IDs are numeric; used as parameters in most other endpoints
• Organization ID may be required; check your PostHog setup
• Pagination is offset-based; iterate until results are empty
• Project settings include API keys and configuration details

5. User Profile and Authentication

When to use: User wants to check current user details or verify API access

Tool sequence:

1. POSTHOG_WHOAMI - Get current API user information [Optional]
2. POSTHOG_RETRIEVE_CURRENT_USER_PROFILE - Get detailed user profile [Optional]

Key parameters:

• No required parameters for either call
• Returns current authenticated user's details, permissions, and organization info

Pitfalls:

• WHOAMI is a lightweight check; use for verifying API connectivity
• User profile includes organization membership and permissions
• These endpoints confirm the API key's access level and scope

Common Patterns

ID Resolution

Organization -> Project ID:

1. Call POSTHOG_LIST_PROJECTS_IN_ORGANIZATION_WITH_PAGINATION
2. Find project by name in results
3. Extract id (numeric) for use in other endpoints

Feature flag name -> Flag ID:

1. Call POSTHOG_LIST_AND_MANAGE_PROJECT_FEATURE_FLAGS with project_id
2. Find flag by key or name
3. Extract id for detailed operations

Feature Flag Targeting

Feature flags support sophisticated targeting:

{
  "filters": {
    "groups": [
      {
        "properties": [
          {"key": "email", "value": "@company.com", "operator": "icontains"}
        ],
        "rollout_percentage": 100
      },
      {
        "properties": [],
        "rollout_percentage": 10
      }
    ]
  }
}

• Groups are evaluated in order; first matching group determines the rollout
• Properties filter users by their traits
• Rollout percentage determines what fraction of matching users see the flag

Pagination

• Events: Use offset and limit (offset-based)
• Feature flags: Use offset and limit (offset-based)
• Projects: Use offset and limit (offset-based)
• Continue until results array is empty or smaller than limit

Known Pitfalls

Project IDs:

• Required for most API endpoints
• Always resolve project names to numeric IDs first
• Multiple projects can exist in one organization

Event Naming:

• System events use $ prefix ($pageview, $identify, $autocapture)
• Custom events should NOT use $ prefix
• Event names are case-sensitive; maintain consistency

Feature Flags:

• Flag keys must be unique within a project
• Use kebab-case for flag keys
• Changes propagate within seconds
• Deleting a flag is permanent; consider disabling instead

Rate Limits:

• Event ingestion has throughput limits
• Batch events where possible for efficiency
• API endpoints have per-minute rate limits

Response Parsing:

• Response data may be nested under data or results key
• Paginated responses include count, next, previous fields
• Event properties are nested objects; access carefully
• Parse defensively with fallbacks for optional fields

When to Use

This skill is applicable to execute the workflow or actions described in the overview.

AGI Framework Integration

Memory-First Protocol

Cache workflow configurations and automation patterns. Retrieve prior pipeline designs to avoid re-building similar flows from scratch.

# Check for prior workflow/automation context before starting
python3 execution/memory_manager.py auto --query "automation patterns and workflow configurations for Posthog Automation"

Storing Results

After completing work, store workflow/automation decisions for future sessions:

python3 execution/memory_manager.py store \
  --content "Workflow: automated data pipeline with retry logic, dead-letter queue, and Slack alerts on failure" \
  --type technical --project <project> \
  --tags posthog-automation workflow

Multi-Agent Collaboration

Share workflow state with other agents so they can trigger, monitor, or extend the automation.

python3 execution/cross_agent_context.py store \
  --agent "<your-agent>" \
  --action "Workflow automation deployed — pipeline processing 1000+ events/day with 99.9% success rate" \
  --project <project>
