Implementation Reference

• server.js:313-329 (handler)

  Handler function for the 'zoom_refresh_token' tool. Instantiates ZoomClient with provided tokens and calls refreshAccessToken method.

  async ({ zoom_access_token, zoom_refresh_token, zoom_client_id, zoom_client_secret }) => {
    try {
      const zoom = new ZoomClient({
        accessToken: zoom_access_token,
        refreshToken: zoom_refresh_token
      });
      
      const result = await zoom.refreshAccessToken(zoom_client_id, zoom_client_secret);
      return {
        content: [{ type: 'text', text: result }]
      };
    } catch (error) {
      return {
        content: [{ type: 'text', text: JSON.stringify({ error: error.message, status: 'error' }) }]
      };
    }
  }

• server.js:308-312 (schema)

  Zod schema defining input parameters for the zoom_refresh_token tool.

    zoom_access_token: z.string().optional().describe('Zoom OAuth2 access token (optional if expired)'),
    zoom_refresh_token: z.string().describe('Zoom OAuth2 refresh token'),
    zoom_client_id: z.string().describe('Zoom OAuth2 client ID for token refresh'),
    zoom_client_secret: z.string().describe('Zoom OAuth2 client secret for token refresh')
  },

• server.js:305-305 (registration)

  Registration of the zoom_refresh_token tool using server.tool().

  'zoom_refresh_token',

• server.js:87-155 (helper)

  ZoomClient method that performs the actual token refresh by making POST to Zoom OAuth endpoint.
