🐾 DevRel MCP (devrel.codingcat.dev)

A production-ready pnpm monorepo for Developer Relations (DevRel) Activity Reporting & Analytics over the Model Context Protocol (MCP).

Hosted on Cloudflare Workers + D1 + Astro at https://devrel.codingcat.dev with full MCP OAuth 2.1 (Protected Resource Metadata, Dynamic Client Registration, PKCE S256, explicit user consent) and AES-256-GCM encrypted per-user credential storage.

✨ Comparison with Original PR #1 & New Capabilities

1. pnpm Monorepo + Astro AEO Frontend (apps/web + packages/mcp-server):

   • Upgraded from a single package with raw HTML into a pnpm workspace serving an Answer Engine Optimized (AEO) Astro site (Schema.org JSON-LD SoftwareApplication, WebAPI, FAQPage, /llms.txt, /llms-full.txt, /robots.txt, /sitemap.xml) alongside the /mcp Streamable HTTP Worker.

2. Email Magic Link, 6-Digit Email OTP, CLI Terminal Verification URL, and Social Login:

   • Email Magic Link & Email OTP via Better Auth (magicLink + emailOTP plugins) with Resend integration and local D1 dev outbox.

   • CLI Terminal Link Flow (/cli-auth): Run npx @codingcatdev/devrel-mcp login in any terminal to get a clickable verification URL (https://devrel.codingcat.dev/cli-auth?code=XXXX-YYYY), approve in the browser, and push fresh tokens (npx @codingcatdev/devrel-mcp push-credentials) directly to your encrypted D1 vault.

   • GitHub / Google / Microsoft OAuth for both sign-in and 1-click provider OAuth connections (/api/provider-oauth/:provider/start).

3. Complete 19-Tool DevRel & Analytics Suite:

   • Google GDE (Advocu — all 7 endpoints): submit_gde_content_creation, submit_gde_public_speaking, submit_gde_workshop, submit_gde_mentoring, submit_gde_product_feedback, submit_gde_googler_interaction, submit_gde_story (completing the missing GDE handlers from the upstream unifiedServer.ts).

   • Microsoft MVP (all 4 activity types): submit_mvp_video, submit_mvp_blog, submit_mvp_speaking, submit_mvp_book.

   • Content & Analytics Auto-Fetch (4 tools): fetch_youtube_video_stats, fetch_devto_articles, fetch_hashnode_posts, fetch_github_activity.

   • Additional DevRel & Ambassador Programs (4 tools): submit_ambassador_advocu_draft (Docker Captains, Cypress Ambassadors, Custom Advocu), log_devrel_activity, list_devrel_activities (AWS Community Builders, CNCF, cross-program D1 ledger), plus list_documentation & get_documentation.

4. Granular Encrypted Credential Storage in Cloudflare D1:

   • Uses Web Crypto AES-256-GCM with a 32-byte key (CREDENTIAL_ENCRYPTION_KEY), random 12-byte IV, and AEAD additionalData bound to user.id.

   • Supports non-destructive PATCH /api/connections updates and per-provider disconnect (DELETE /api/connections?provider=...) in addition to full PUT /api/connections.

🚀 Quick Start (Local Hosted Development)

Prerequisites

• Node.js 22.12+

• pnpm 9+

# 1. Install dependencies across the monorepo
pnpm install

# 2. Configure local Worker secrets
cp .dev.vars.example apps/web/.dev.vars
# Edit apps/web/.dev.vars and set two independent 32-byte base64 secrets:
# openssl rand -base64 32

# 3. Apply D1 migrations locally
pnpm db:migrate:local

# 4. Build packages & start local Cloudflare Worker at http://localhost:8787
pnpm dev:hosted

Run End-to-End Tests

pnpm test

☁️ Deploying to devrel.codingcat.dev

1. Authenticate Wrangler and create the production D1 database:

   pnpm --filter @codingcatdev/devrel-web exec wrangler login
   pnpm --filter @codingcatdev/devrel-web exec wrangler d1 create devrel-mcp

2. Update database_id in apps/web/wrangler.jsonc with the returned D1 database ID.

3. Configure production secrets:

   cd apps/web
   npx wrangler secret put BETTER_AUTH_SECRET --env production
   npx wrangler secret put CREDENTIAL_ENCRYPTION_KEY --env production
   npx wrangler secret put RESEND_API_KEY --env production
   # Optional OAuth providers:
   npx wrangler secret put GITHUB_CLIENT_ID --env production
   npx wrangler secret put GITHUB_CLIENT_SECRET --env production

4. Apply remote D1 migrations and deploy:

   npx wrangler d1 migrations apply DB --remote --env production
   pnpm build && npx wrangler deploy --env production

5. Connect your MCP client to https://devrel.codingcat.dev/mcp:

   claude mcp add --transport http devrel https://devrel.codingcat.dev/mcp
