HTML page: https://policylayer.com/tools/app-businys-mcp-server/list-credit-history ## Facts - Tool: `list_credit_history` - Server: Businys (`@businys/mcp-server`) — https://policylayer.com/tools/app-businys-mcp-server.md - Install: `npx -y @businys/mcp-server` - Homepage: https://github.com/hiatys/businys-mcp - 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": "list_credit_history", "arguments": {} } } ``` ## Why list_credit_history is rated Low This tool queries and retrieves credit transaction records. It is informational only—viewing a transaction log does not create, modify, delete, or execute any operations. The blast radius of misuse is minimal since an agent simply gains visibility into past credit activity without ability to alter balances or trigger financial movements. From the tool's own definition: "Tool name 'list_credit_history' and description 'Transaction log for a credit pack: credits used, expired, makeup credits granted' indicate retrieval of historical transaction data with no modification or side effects." ## Use case AI agents call list_credit_history to retrieve information from Businys 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 Businys: ```json { "version": "1", "default": "deny", "tools": { "list_credit_history": {} } } ``` ## Other tools on Businys (247) - `archive_contract` — Destructive — https://policylayer.com/tools/app-businys-mcp-server/archive-contract.md - `archive_invoice` — Destructive — https://policylayer.com/tools/app-businys-mcp-server/archive-invoice.md - `cancel_booking` — Destructive — https://policylayer.com/tools/app-businys-mcp-server/cancel-booking.md - `cancel_invitation` — Destructive — https://policylayer.com/tools/app-businys-mcp-server/cancel-invitation.md - `delete_account` — Destructive — https://policylayer.com/tools/app-businys-mcp-server/delete-account.md - `delete_asset` — Destructive — https://policylayer.com/tools/app-businys-mcp-server/delete-asset.md - `delete_automation` — Destructive — https://policylayer.com/tools/app-businys-mcp-server/delete-automation.md - `delete_blackout` — Destructive — https://policylayer.com/tools/app-businys-mcp-server/delete-blackout.md - `delete_exercise` — Destructive — https://policylayer.com/tools/app-businys-mcp-server/delete-exercise.md - `delete_gear_item` — Destructive — https://policylayer.com/tools/app-businys-mcp-server/delete-gear-item.md - `delete_goal` — Destructive — https://policylayer.com/tools/app-businys-mcp-server/delete-goal.md - `delete_measurement` — Destructive — https://policylayer.com/tools/app-businys-mcp-server/delete-measurement.md - `delete_personal_record` — Destructive — https://policylayer.com/tools/app-businys-mcp-server/delete-personal-record.md - `delete_program` — Destructive — https://policylayer.com/tools/app-businys-mcp-server/delete-program.md - `delete_sub_profile` — Destructive — https://policylayer.com/tools/app-businys-mcp-server/delete-sub-profile.md - `delete_workout` — Destructive — https://policylayer.com/tools/app-businys-mcp-server/delete-workout.md - `delete_workout_set` — Destructive — https://policylayer.com/tools/app-businys-mcp-server/delete-workout-set.md - `remove_member` — Destructive — https://policylayer.com/tools/app-businys-mcp-server/remove-member.md - `revoke_api_key` — Destructive — https://policylayer.com/tools/app-businys-mcp-server/revoke-api-key.md - `revoke_portal_access` — Destructive — https://policylayer.com/tools/app-businys-mcp-server/revoke-portal-access.md - `skip_nurture` — Destructive — https://policylayer.com/tools/app-businys-mcp-server/skip-nurture.md - `create_automation` — Execute — https://policylayer.com/tools/app-businys-mcp-server/create-automation.md - `switch_organization` — Execute — https://policylayer.com/tools/app-businys-mcp-server/switch-organization.md - `cancel_recurring_billing` — Financial — https://policylayer.com/tools/app-businys-mcp-server/cancel-recurring-billing.md - `create_credit_pack` — Financial — https://policylayer.com/tools/app-businys-mcp-server/create-credit-pack.md - `create_deposit_invoice` — Financial — https://policylayer.com/tools/app-businys-mcp-server/create-deposit-invoice.md - `create_recurring_billing` — Financial — https://policylayer.com/tools/app-businys-mcp-server/create-recurring-billing.md - `deduct_credit` — Financial — https://policylayer.com/tools/app-businys-mcp-server/deduct-credit.md - `forfeit_deposit` — Financial — https://policylayer.com/tools/app-businys-mcp-server/forfeit-deposit.md - `pause_recurring_billing` — Financial — https://policylayer.com/tools/app-businys-mcp-server/pause-recurring-billing.md - …and 217 more: https://policylayer.com/tools/app-businys-mcp-server.md ## For agents This record is a snapshot.
