Available Tools

Markdown Support

This server automatically converts between Markdown and Evernote's ENML format:

• Create/update: Markdown input is rendered to ENML-safe HTML inside <en-note>.
  • GFM task lists - [ ] map to Evernote checkboxes <en-todo/>.
  • Checked tasks - [x] map to <en-todo checked="true"/>.
• • Local Markdown images/files (![alt](./path.png) or file://...) are uploaded as Evernote resources automatically.
• • Existing attachments are preserved by referencing evernote-resource:<hash> in Markdown.
• • Remote http(s) images remain links (download locally if you want them embedded).
• • Common Markdown elements (headings, lists, code blocks, tables, emphasis, links) are preserved.
• Retrieve: ENML content is converted back to Markdown (GFM), including task lists and attachments.
  • Embedded images become ![alt](evernote-resource:<hash>) and other files become [file](evernote-resource:<hash>) so you can round-trip them safely.

Limitations:

• Remote URLs are not fetched automatically; save them locally and reference the file to embed.
• Keep the evernote-resource:<hash> references in Markdown if you want existing attachments to survive edits.
• Some exotic HTML not supported by ENML will be sanitized/removed.

Integration with Claude Automation Hub

// Example workflow tool
export default {
  name: 'capture-idea',
  description: 'Capture an idea to Evernote',
  handler: async ({ idea, category }) => {
    // The MCP server handles the Evernote integration
    return {
      tool: 'evernote_create_note',
      args: {
        title: `Idea: ${new Date().toISOString().split('T')[0]}`,
        content: idea,
        notebookName: 'Ideas',
        tags: [category, 'automated']
      }
    };
  }
};

Memory Service Integration

To enable synchronization with MCP memory service:

1. Set the memory service URL in your environment:

MCP_MEMORY_SERVICE_URL=http://localhost:8765

2. Use the sync tools to persist important notes to memory:

Sync my "Important Concepts" notebook to memory for long-term retention

Troubleshooting

Authentication Issues

"Authentication required" error in Claude Desktop

This means you haven't authenticated yet. Run the authentication script:

npx -p @verygoodplugins/mcp-evernote mcp-evernote-auth

Or if installed globally:

mcp-evernote-auth

OAuth callback fails

If the OAuth callback doesn't work:

1. Make sure port 3000 is available (or set OAUTH_CALLBACK_PORT in .env)
2. Check your firewall settings
3. Try using a different browser

Token expired

If your token expires:

1. Delete .evernote-token.json
2. Run npx -p @verygoodplugins/mcp-evernote mcp-evernote-auth again
3. Restart Claude Desktop

Connection Errors

• Verify your API credentials are correct
• Check if you're using the right environment (sandbox vs production)
• Ensure your firewall allows the OAuth callback port

Rate Limiting

Evernote API has rate limits. If you encounter limits:

• Reduce the frequency of requests
• Use batch operations where possible
• Implement caching for frequently accessed data

Development

Building from Source

npm install
npm run build

Running in Development Mode

Security

• OAuth tokens are stored locally in .evernote-token.json
• Never commit token files to version control
• Use environment variables for sensitive configuration
• Tokens expire after one year by default
