DRUPAL ORG MODULES CATALOG

Drupal.org Module Catalog

  7. drupal/jsonapi_extras - Enhanced JSON:API
  8. drupal/webform - Form builder

Use With Caution (6 modules)

  1. drupal/ai_orchestrator - NEW, workflow storage only, no security coverage
  2. drupal/ai_search - Alpha release, semantic search
  3. drupal/ai_content - Incomplete documentation, minimal activity
  4. drupal/flowdrop - No security coverage, active development
  5. drupal/flowdrop_ai_provider - NEW, dev-only, no security coverage
  6. drupal/flowdrop_ui_agents - VERY NEW, dev-only, no security coverage

Abandoned - Do Not Use (2 modules)

  1. drupal/gitlab - Last updated 2014
  2. drupal/gitlab_integration - Inactive since 2021

Does Not Exist (5 modules)

  1. drupal/ai_mcp - Model Context Protocol (check if in AI core)
  2. drupal/ai_vector - Vector DB (likely in ai_search or ai core)
  3. drupal/ai_anthropic - Anthropic provider (likely in AI core)
  4. drupal/ai_openai - OpenAI provider (likely in AI core)
  5. drupal/ai_langchain - LangChain integration (may not be needed)

Critical Modules for Agent Platform

Must Have (Priority 1)

  1. drupal/ai (1.2.5) - Foundation for all AI work
  2. drupal/ai_agents (1.2.1) - Agent framework
  3. drupal/key (8.x-1.21) - Secure credential storage

Should Have (Priority 2)

  1. drupal/eca (3.0.9) - Visual workflow automation
  2. drupal/graphql (8.x-4.13) - API layer for agent communication
  3. drupal/jsonapi_extras (8.x-3.28) - Enhanced REST API

Consider (Priority 3)

  1. drupal/ai_search (2.0.0-alpha1) - Semantic search (when stable)
  2. drupal/rules (4.0.0) - If ECA doesn't meet all needs
  3. drupal/webform (6.2.9) - Form-based agent interactions

Monitor/Evaluate

  1. drupal/flowdrop - Visual workflow alternative to ECA
  2. drupal/flowdrop_ui_agents - Visual agent design (very new)
  3. drupal/ai_orchestrator - If need advanced workflow storage

Next Steps

1. Verify AI Module Providers

Need to confirm which AI providers are included in drupal/ai:

  • Check if Anthropic/Claude provider exists
  • Check if OpenAI provider exists
  • Verify vector database support location
  • Check MCP support

Action: Download and inspect drupal/ai module code to document all sub-modules and providers

2. Evaluate FlowDrop vs ECA

Both provide visual workflow building:

  • ECA: Mature, stable, security-covered, 11K+ sites
  • FlowDrop: New, AI-focused, no security coverage

Action: Test both to determine which better fits agent platform needs

3. Custom Module Needs

Based on missing modules, may need to build:

  • GitLab API integration (both existing options abandoned)
  • Anthropic provider (if not in AI core)
  • MCP integration (if not in AI core)

4. Security Review

All modules with security warnings need:

  • Code audit before production use
  • Regular monitoring for updates
  • Consider contributing security policy coverage

Research Methodology

  • Date: 2026-01-08
  • Method: Direct WebFetch to Drupal.org project pages
  • Coverage: 20 modules researched
  • Success Rate: 13 found (65%), 5 not found (25%), 2 abandoned (10%)

Maintenance Notes

  • Update this catalog monthly or when adding new module dependencies
  • Track module version updates for security and compatibility
  • Monitor issue queues for critical bugs before adoption
  • Contribute back to community modules we use heavily
