Dabble MCP Server

Dabble Me

A private journal over email service.

Dabble Me helps people remember what's happened in their life. Use it as a light-weight journal on a daily, weekly, or even monthly basis...it's up to you! Dabble Me will email you on a time & days you choose - you simply reply to the email to post entries. The app is live at https://dabble.me. This is a great replacement if you had ever used OhLife.

This app utilizes the following 3rd party services:

• CloudFlare managed DNS + free SSL support (free for basic service)
• Mailgun for Sending & Receiving Email (free for 50k emails per month)
• Amazon S3 for Photo Uploads & Storage (free for 1 year)
• Google Analytics for traffic stats (free for standard analytics)
• Turnstile to prevent bot signups (free).
• Sentry to report errors (free)

You will need to setup Mailgun to receive incoming emails and point them to your app to parse.

Scheduled jobs (including hourly email sending) are run by sidekiq-cron inside the Sidekiq worker process. The schedule lives in config/schedule.yml. No external scheduler is required.

Your local environment variables at config/local_env.yml (and on Railway) will need to be something like this (rake db:seed will create the admin@dabble.ex account for you):

MAIN_DOMAIN: yourdomain.com
SECRET_KEY_BASE: 1234..1234
DEVISE_SECRET_KEY: 1234..1234
SMTP_DOMAIN: post.yourdomain.com
MAILGUN_API_KEY=api-key
TURNSTILE_SITE_KEY: 6Lc6BAAAAAAAAChqRbQZcn_yyyyyyyyyyyyyyyyy
TURNSTILE_SECRET_KEY: 6Lc6BAAAAAAAAKN3DRm6VA_xxxxxxxxxxxxxxxxx
GOOGLE_ANALYTICS_ID=UA-12345-67 ## ONLY FOR PRODUCTION
SENTRY_DSN: https://dsn.sentry.io/1234
OPENAI_ACCESS_TOKEN: sk-1234
OPENAI_ORGANIZATION_ID: org-1234
HUGGING_FACE_API_KEY: 1234
STRIPE_API_KEY: sk_test_1234
STRIPE_SIGNING_SECRET: whsec_1234

Things you may want to rip out

You can opt to not use Turnstile: simply don't add an environment variables for TURNSTILE_SITE_KEY.

MCP (Model Context Protocol)

PRO accounts can use Dabble Me as a remote MCP server so compatible clients (for example Claude) can search, list, analyze, and create journal entries after OAuth.

Requirements: PRO subscription, plus a passkey or two-factor authentication on Account security (/security). Connected OAuth apps can be reviewed and revoked on the same page under Connected apps (shown only when something is connected).

Endpoint: Streamable HTTP at https://<MAIN_DOMAIN>/mcp (see MAIN_DOMAIN in config/local_env.yml). The client should use OAuth: authorization metadata is published under /.well-known/oauth-authorization-server and /.well-known/oauth-protected-resource (see Oauth::MetadataController).

User-facing instructions: Dabble Me MCP Server at /mcp-server on your host.

Deep links for assistants: a single day opens at https://<MAIN_DOMAIN>/entries/YYYY/M/D with unpadded month and day (example: https://dabble.me/entries/2026/4/21). The web compose URL is https://<MAIN_DOMAIN>/write.

For generic remote-connector setup in Claude, see Anthropic’s Get started with custom connectors using remote MCP.

Registry metadata: server.json describes the hosted Streamable HTTP endpoint for the official MCP Registry.

WebMCP / AI-client discovery: public pages advertise /.well-known/webmcp, /mcp/server-card, and /.well-known/ai-catalog.json. In a signed-in browser tab, WebMCP also registers session journal tools (search, list, analyze, open a day, draft an entry without submitting). Search/analyze/draft need PRO. Remote MCP at /mcp still uses OAuth (PRO + passkey or 2FA). For the WebMCP Challenge, put a dedicated PRO demo account (email/password, no 2FA) on the submission form — do not use a real journal.

Automated smoke (curl + MCP Inspector CLI): ./script/mcp_inspector_smoke.sh uses RAILS_ENV=test, starts a short-lived Rails server, checks OAuth metadata and /mcp, then runs Inspector against all five tools (tools/list exercises initialize + connect). Aligns with Anthropic’s Testing your connector guidance.

Tests

There is healthy coverage of the app, which you can run with:

rake

Administration Portal

The Admin emails are accounts that have access to the Admin Dropdown in the navbar (lock icon) that give you details into the number of entries and users in the system.

Inspirations and Importers

If you want random bits of inspiration, you can load up different quotes in the Inspiration table to be shown above the New Posts page and at the bottom of emails. Import sources are tagged via Inspiration categories — seed OhLife / Ahhlife / Day One / Trailmix rows (see db/seeds.rb), or the Day One importer will create its category on first use.

Inspiration.create(category: 'OhLife', body: 'Imported from OhLife')
Inspiration.create(category: 'Day One', body: 'Imported from Day One')

PRO users can import from OhLife (text + photo ZIP), Day One (JSON ZIP export), Ahhlife (JSON paste), and Trailmix.life (JSON upload) at /entries/import.
