AI agents call search-flights to retrieve information from Amadeus MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool searches and retrieves flight information from the Amadeus API. It has no side effects—it does not book flights, charge money, modify data, or execute external operations beyond querying. Even though it operates in a travel domain, the action is purely informational retrieval, fitting the Read category.
From the tool's definition Tool name 'search-flights' and description 'Search for flight offers' indicate a query operation that retrieves flight data without modifying or executing transactions.
Documented attack patterns abuse exactly the kind of access search-flights gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Amadeus MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search-flights:
{
"version": "1",
"default": "deny",
"tools": {
"search-flights": {}
}
}search-flights is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search for flight offers. It is categorised as a Read tool in the Amadeus MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Amadeus MCP Server MCP server in PolicyLayer and add a rule for search-flights: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Amadeus MCP Server. Nothing to install.
search-flights is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the search-flights rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for search-flights. 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.
search-flights is provided by the Amadeus MCP Server MCP server (privilegemendes/amadeus-mcp-server-standalone). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Amadeus MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
