Nylas API MCP Server

### Connected Accounts changed to Grants In Nylas v3, the concept of "grants" (as in, "the end user _granted_ you this access") replaces "connected accounts". This name better reflects the new offering and lays the groundwork for future enhancements and features. - Nylas APIs now return a `grant_id` instead of an `account_id`. - All Email, Calendar, and Contacts APIs include the `/v3/grants/<NYLAS_GRANT_ID>` prefix. - You can refer to an end user's grant using their `grant_id`, their email address, or (if you're using an access token for their grant), the `/me/` construction. - The `account.invalid` webhook trigger is deprecated. You should subscribe to `grant.expired` instead. ### New Grants endpoints - Update a grant: [`PATCH /v3/grants/<NYLAS_GRANT_ID>`](https://developer.nylas.com/docs/api/v3/admin/#patch-/v3/grants/-grantId-) - Get the current grant: [`GET /v3/grants/me`](https://developer.nylas.com/docs/api/v3/admin/#get-/v3/grants/me) ### Migrated Accounts endpoints - Return all grants: `GET /a/<NYLAS_CLIENT_ID>` → [`GET /v3/grants`](https://developer.nylas.com/docs/api/v3/admin/#get-/v3/grants) - Return a specific grant: `GET /a/<NYLAS_CLIENT_ID>/accounts/<NYLAS_ACCOUNT_ID>` → [`GET /v3/grants/<NYLAS_GRANT_ID>`](https://developer.nylas.com/docs/api/v3/admin/#get-/v3/grants/-grantId-) - Delete a grant: `DELETE /a/<NYLAS_CLIENT_ID>/accounts/<NYLAS_ACCOUNT_ID>` → [`DELETE /v3/grants/<NYLAS_GRANT_ID>`](https://developer.nylas.com/docs/api/v3/admin/#delete-/v3/grants/-grantId-) ### Deprecated Accounts endpoints - Cancel an account: `POST /a/<NYLAS_CLIENT_ID>/accounts/<NYLAS_ACCOUNT_ID>/downgrade` - Reactivate an account: `POST /a/<NYLAS_CLIENT_ID>/accounts/<NYLAS_ACCOUNT_ID>/upgrade` - Revoke all tokens: `POST /a/<NYLAS_CLIENT_ID>/accounts/<NYLAS_ACCOUNT_ID>/revoke-all` - Return token information: `POST /a/<NYLAS_CLIENT_ID>/accounts/<NYLAS_ACCOUNT_ID>/token-info` - Revoke an access token: `POST /oauth/revoke` - Return account details: `GET /account`
