WHAT IT DOES

What findSwiftCodes does on API Ninjas

AI agents call findSwiftCodes to retrieve information from API Ninjas without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`bank`	string	—	The name of the bank to look up. This parameter supports partial matching (e.g., Silicon Valley will match Silicon Valley Bank). Premium only.
`city`	string	—	Name of the city in which the bank is located.
`swift`	string	—	The SWIFT Code of the bank to look up.
`offset`	integer	—	The number of results to offset for pagination. Default is 0. Annual premium subscriptions only.
`country`	string	—	ISO 3166 2-letter country code of the bank's country.
`routing_number`	string	—	9-digit US ABA routing number. Returns the SWIFT/BIC codes of the US bank identified by the routing number. Available for Business and Professional subscribers

Parameters from the server's own tool schema.

RISK

Why findSwiftCodes is rated Low

Even though findSwiftCodes only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs findSwiftCodes safely

PolicyLayer is an MCP gateway: it sits between your AI agents and API Ninjas, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For findSwiftCodes, this is the rule to start with:

findSwiftCodes Allowed

findSwiftCodes is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "findSwiftCodes": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect API Ninjas, apply this rule, and every findSwiftCodes call is checked against it from then on.

How do I block findSwiftCodes completely? +

Set action: deny in the PolicyLayer policy for findSwiftCodes. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides findSwiftCodes? +

findSwiftCodes is provided by the API Ninjas MCP server (https://mcp.api-ninjas.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
