Instructions

Implementation Reference

• src/tools/account.ts:179-188 (handler)

  MCP tool handler for 'telegraph_revoke_access_token': validates input using Zod schema and delegates to telegraph.revokeAccessToken client function, returning JSON response.

  case 'telegraph_revoke_access_token': {
    const input = RevokeAccessTokenSchema.parse(args);
    const result = await telegraph.revokeAccessToken(input.access_token);
    return {
      content: [{
        type: 'text' as const,
        text: JSON.stringify(result, null, 2),
      }],
    };
  }

• src/telegraph-client.ts:121-125 (helper)

  Core implementation of revokeAccessToken: makes HTTP POST to Telegraph API endpoint '/revokeAccessToken' using the shared apiRequest utility.

  export async function revokeAccessToken(access_token: string): Promise<Account> {
    return apiRequest<Account>('revokeAccessToken', {
      access_token,
    });
  }

• src/tools/account.ts:31-33 (schema)

  Zod input validation schema for the telegraph_revoke_access_token tool requiring 'access_token' string.

  export const RevokeAccessTokenSchema = z.object({
    access_token: z.string().describe('Access token of the Telegraph account'),
  });

• src/tools/account.ts:115-128 (registration)

  Tool registration in accountTools array: defines name, description, and JSON inputSchema for MCP server registration.

  {
    name: 'telegraph_revoke_access_token',
    description: 'Revoke the current access_token and generate a new one. The old token becomes invalid immediately.',
    inputSchema: {
      type: 'object' as const,
      properties: {
        access_token: {
          type: 'string',
          description: 'Access token of the Telegraph account to revoke',
        },
      },
      required: ['access_token'],
    },
  },
