# isw_get_transaction_by_reference Get Quickteller transaction by transactionRef query. Agent View of the PolicyLayer registry record for `isw_get_transaction_by_reference`. HTML page: https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-get-transaction-by-reference ## Facts - Tool: `isw_get_transaction_by_reference` - Server: Interswitch (`interswitch-mcp-server`) — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server.md - Install: `npx -y interswitch-mcp-server` - Homepage: https://github.com/Dairus01/Interswitch-mcp-server - Risk category: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "isw_get_transaction_by_reference", "arguments": {} } } ``` ## Why isw_get_transaction_by_reference is rated Low This tool retrieves transaction information by reference identifier. The verb 'Get' and the query pattern are characteristic of read-only operations. No side effects, mutations, financial transfers, or destructive actions are performed. The blast radius is minimal—an AI agent misusing this tool would only retrieve unintended transaction details, not cause financial harm or irreversible changes. From the tool's own definition: "Tool name 'isw_get_transaction_by_reference' and description 'Get Quickteller transaction by transactionRef query' indicate a retrieval operation that queries transaction data without modifying or executing anything." ## Use case AI agents call isw_get_transaction_by_reference to retrieve information from Interswitch without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Interswitch: ```json { "version": "1", "default": "deny", "tools": { "isw_get_transaction_by_reference": {} } } ``` ## Other tools on Interswitch (73) - `isw_block_card` — Destructive — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-block-card.md - `isw_deactivate_paycode` — Destructive — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-deactivate-paycode.md - `isw_agency_requery_xml` — Execute — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-agency-requery-xml.md - `isw_fintech_build_response` — Execute — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-fintech-build-response.md - `isw_fintech_compute_mac` — Execute — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-fintech-compute-mac.md - `isw_agency_banking_cashout` — Financial — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-agency-banking-cashout.md - `isw_agency_cashout_xml` — Financial — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-agency-cashout-xml.md - `isw_airtime_recharge` — Financial — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-airtime-recharge.md - `isw_bulk_card_production` — Financial — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-bulk-card-production.md - `isw_bulk_transfer` — Financial — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-bulk-transfer.md - `isw_complete_credit` — Financial — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-complete-credit.md - `isw_create_bulk_paycodes` — Financial — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-create-bulk-paycodes.md - `isw_create_card` — Financial — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-create-card.md - `isw_create_paycode` — Financial — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-create-paycode.md - `isw_create_payment_link` — Financial — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-create-payment-link.md - `isw_get_airtime_epins` — Financial — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-get-airtime-epins.md - `isw_initialize_payment` — Financial — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-initialize-payment.md - `isw_initiate_refund` — Financial — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-initiate-refund.md - `isw_pay_bill` — Financial — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-pay-bill.md - `isw_pay_vas_bill` — Financial — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-pay-vas-bill.md - `isw_request_nano_loan` — Financial — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-request-nano-loan.md - `isw_salary_lending` — Financial — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-salary-lending.md - `isw_single_transfer` — Financial — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-single-transfer.md - `isw_value_financing` — Financial — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-value-financing.md - `isw_agency_get_token` — Read — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-agency-get-token.md - `isw_block_prepaid_card` — Read — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-block-prepaid-card.md - `isw_check_debit_balance` — Read — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-check-debit-balance.md - `isw_check_prepaid_balance` — Read — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-check-prepaid-balance.md - `isw_confirm_debit_sufficient` — Read — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-confirm-debit-sufficient.md - `isw_confirm_prepaid_sufficient` — Read — https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server/isw-confirm-prepaid-sufficient.md - …and 43 more: https://policylayer.com/tools/io-github-dairus01-interswitch-mcp-server.md ## For agents This record is a snapshot.
