Implementation Reference
- src/services.ts:872-931 (handler)The async handler function for the 'account_export_account' tool. It connects to the blockchain, gets the account, retrieves the keypair from the keystore, and writes the account details (account_id, public_key, private_key) to a JSON file.
async (args, _) => { const connection = await connect({ networkId: args.networkId, nodeUrl: getEndpointsByNetwork(args.networkId)[0]!, }); const accountResult: Result<Account, Error> = await getAccount( args.accountId, connection, ); if (!accountResult.ok) { return { content: [{ type: 'text', text: `Error: ${accountResult.error}` }], }; } const keypairResult: Result<KeyPair, Error> = await getAccountKeyPair( args.accountId, args.networkId, keystore, ); if (!keypairResult.ok) { return { content: [{ type: 'text', text: `Error: ${keypairResult.error}` }], }; } const keypair = keypairResult.value; const writeKeyFileResult: Result<void, Error> = await (async () => { try { const filePayload = { account_id: args.accountId, public_key: keypair.getPublicKey().toString(), private_key: keypair.toString(), }; const filePath = args.filePath || `${args.accountId}.${args.networkId}.json`; await writeFile(filePath, JSON.stringify(filePayload, null, 2)); return { ok: true, value: undefined }; } catch (e) { return { ok: false, error: new Error(e as string) }; } })(); if (!writeKeyFileResult.ok) { return { content: [ { type: 'text', text: `Error: ${writeKeyFileResult.error}` }, ], }; } return { content: [ { type: 'text', text: `Account ${args.accountId} exported to ${args.filePath}`, }, ], }; }, ); - src/services.ts:862-871 (schema)The input schema for 'account_export_account' tool: accountId (string), networkId (enum: testnet/mainnet, default mainnet), and optional filePath.
