Open Source

Production open-source software from Wilkes & Liberty — Drupal modules and MCP tooling for the seam between AI agents and systems of record, released with no telemetry and no lock-in.

We build and maintain open-source tools you can inspect, operate, and change. Everything here is production software we use in our own engagements and release under open-source licenses stated in each repository — Drupal modules under GPL — with no gated “community editions,” no telemetry, and no lock-in.

Our projects cover AI-agent access, audit records, field-level permissions, private file delivery, content-driven navigation, frontend code generation, and email delivery controls. The catalog below includes Drupal modules and MCP tooling.

Never stop building.

Projects

Open source

Postmark Webhooks

Receive Postmark delivery events, retain suppression evidence, and stop Drupal mail to blocked recipients. Optional modules integrate Mailer Plus and reconcile provider suppression records.
Open source

Field Guard

Config-driven Drupal field access that fails closed for values, JSON:API filters, and Views sorting, while requiring explicit non-administrator role grants for sensitive fields.
Open source

Audit Chain

A reusable Drupal audit service that detects inserted, deleted, reordered, or edited history through one hash-chained sequence, with optional HMAC signing, encryption, rotation support, and independent Drush verification.
Open source

File Gate

Private-file delivery for Drupal after a real gate: short-lived signed grants, eight shipped access methods, revocation and usage controls, optional hardware-backed assurance, and a framework-neutral API.
Open source

Menu Autopilot

Hybrid Drupal navigation for editors and site builders: curate each parent, then reconcile ordinary menu-link children from taxonomy, content bundles, or an ordered node list.
Open source

GraphQL Compose Codegen

Drush-powered TypeScript, GraphQL fragment, and React scaffold generation from Drupal’s live GraphQL Compose schema, with CI drift detection for headless frontend contracts.
Open source

MCP Sentinel

Server-side governance for authenticated AI-agent access to Drupal: OAuth-scoped policy profiles, publish gates, redaction and DLP, quotas, approvals, reliable webhooks, and tamper-evident audit evidence.
Open source

Drupal MCP Connector

A secure Node.js Model Context Protocol connector for one or many Drupal sites, with governed content operations, dual JSON:API/GraphQL reads, audits, dry runs, and an optional Drush bridge.
