  The core handler function in NewRelicClient that executes a NerdGraph GraphQL query to fetch and return account details (ID and name) for the specified account ID.
  async getAccountDetails(accountId?: string): Promise<AccountDetails> { const id = accountId || this.defaultAccountId; if (!id) { throw new Error('Account ID must be provided'); } type AccountResponse = { actor?: { account?: { id: string; name: string } } }; const query = `{ actor { account(id: ${id}) { id name } } }`; const response = (await this.executeNerdGraphQuery<AccountResponse>( query )) as GraphQLResponse<AccountResponse>; if (!response.data?.actor?.account) { throw new Error(`Account ${id} not found`); } return { accountId: response.data.actor.account.id, name: response.data.actor.account.name, }; }
• src/server.ts:89-100 (registration)

  Tool registration definition including name, description, and input schema. Added to the tools array and registered via this.tools.set().
  name: 'get_account_details', description: 'Get New Relic account details', inputSchema: { type: 'object' as const, properties: { target_account_id: { type: 'string' as const, description: 'Optional account ID to get details for', }, }, }, },

• src/client/newrelic-client.ts:19-23 (schema)
