Implementation Reference

• src/auth-tools.ts:168-209 (registration)

  MCP tool registration for 'remove-account', including input schema (accountId: string), description, and handler function that delegates to AuthManager.removeAccount and returns success/error message

  server.tool(
    'remove-account',
    'Remove a Microsoft account from the cache',
    {
      accountId: z.string().describe('The account ID to remove'),
    },
    async ({ accountId }) => {
      try {
        const success = await authManager.removeAccount(accountId);
        if (success) {
          return {
            content: [
              {
                type: 'text',
                text: JSON.stringify({ message: `Removed account: ${accountId}` }),
              },
            ],
          };
        } else {
          return {
            content: [
              {
                type: 'text',
                text: JSON.stringify({ error: `Account not found: ${accountId}` }),
              },
            ],
          };
        }
      } catch (error) {
        return {
          content: [
            {
              type: 'text',
              text: JSON.stringify({
                error: `Failed to remove account: ${(error as Error).message}`,
              }),
            },
          ],
        };
      }
    }
  );

• src/auth-tools.ts:172-172 (schema)

  Input schema validation using Zod for the accountId parameter

  accountId: z.string().describe('The account ID to remove'),

• src/auth-tools.ts:174-208 (handler)

  Handler function for 'remove-account' tool that calls AuthManager.removeAccount(accountId) and formats the response as MCP content

  async ({ accountId }) => {
    try {
      const success = await authManager.removeAccount(accountId);
      if (success) {
        return {
          content: [
            {
              type: 'text',
              text: JSON.stringify({ message: `Removed account: ${accountId}` }),
            },
          ],
        };
      } else {
        return {
          content: [
            {
              type: 'text',
              text: JSON.stringify({ error: `Account not found: ${accountId}` }),
            },
          ],
        };
      }
    } catch (error) {
      return {
        content: [
          {
            type: 'text',
            text: JSON.stringify({
              error: `Failed to remove account: ${(error as Error).message}`,
            }),
          },
        ],
      };
    }
  }

• src/auth.ts:507-533 (helper)

  Core implementation in AuthManager.removeAccount: finds account by homeAccountId, removes from MSAL token cache, clears selection if needed

  async removeAccount(accountId: string): Promise<boolean> {
    const accounts = await this.listAccounts();
    const account = accounts.find((acc: AccountInfo) => acc.homeAccountId === accountId);
  
    if (!account) {
      logger.error(`Account with ID ${accountId} not found`);
      return false;
    }
  
    try {
      await this.msalApp.getTokenCache().removeAccount(account);
  
      // If this was the selected account, clear the selection
      if (this.selectedAccountId === accountId) {
        this.selectedAccountId = null;
        await this.saveSelectedAccount();
        this.accessToken = null;
        this.tokenExpiry = null;
      }
  
      logger.info(`Removed account: ${account.username} (${accountId})`);
      return true;
    } catch (error) {
      logger.error(`Failed to remove account ${accountId}: ${(error as Error).message}`);
      return false;
    }
  }

• src/server.ts:83-84 (registration)

  Call to registerAuthTools which includes the 'remove-account' tool registration (conditional on !options.http || options.enableAuthTools)

    registerAuthTools(this.server, this.authManager, this.graphClient);
  }
