Environment Variables

This project requires a Dex API key. Never commit your real API key to a public repository.

1. Copy .env.example to .env:

   cp .env.example .env

   

2. Edit .env and set your real Dex API key:

   DEX_API_KEY=your-dex-api-key-here

Allowed Meeting Types for Notes

When creating a note, you may specify the meeting type using either the display name or the Dex API enum value. The following table shows the accepted values:

| Display Name | Dex API Enum Value |
|-------------------|---------------------|
| Note | note |
| Call | call |
| Email | email |
| Text/Messaging | text_messaging |
| Linkedin | linkedin |
| Skype/Teams | skype_teams |
| Slack | slack |
| Coffee | coffee |
| Networking | networking |
| Party/Social | party_social |
| Other | other |
| Meal | meal |
| Meeting | meeting |
| Custom | custom |

You may use any of the above display names (case-insensitive, spaces and slashes allowed) or the exact enum value. The system will automatically map your input to the correct Dex API value.

Example Use Cases

- "Add John Smith from TechCorp as a new contact"
- "Set a reminder to follow up with Sarah next week"
- "Search for all notes about the ABC project"
- "Update Mike's job title to Senior Engineer"
- "Show me all pending reminders for this month"
- "Create a note about today's meeting with the client"

Development

Scripts

- npm run build - Compile TypeScript - npm run dev - Run with ts-node for development - npm run watch - Watch mode compilation - npm start - Run compiled server

Architecture

- TypeScript for type safety - Zod for schema validation - Axios for HTTP requests to Dex API - MCP SDK for protocol implementation

API Integration

This server integrates with the Dex API using:
- GraphQL endpoint: https://api.getdex.com/v1/graphql
- Timeline items for note storage
- Reminders table with contact junction
- Proper pagination and search capabilities

Code Quality & CI

This project uses TypeScript for type safety and ESLint for code linting. All code is automatically checked for type errors and lint issues in CI (see .github/workflows/ci.yml).

- Run type checks locally:

  npm run build # or npx tsc --noEmit

  

- Run linter locally:

  npm run lint

  

All pull requests must pass CI checks before merging.

Issue & PR Templates

- Bug reports and feature requests use GitHub issue templates for consistency.
- All pull requests use a PR template to ensure quality and documentation.

Security & Secrets

- Never commit secrets or API keys. .env is gitignored and secrets are loaded from environment variables.
- If a secret is ever committed, follow the repo's history-scrubbing protocol (see scrub-git-history.sh).
