Discover available tools based on natural language queries.
AI agents call discover to retrieve information from Qveris Agent Toolkit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a lookup and discovery operation that retrieves information about available tools. It does not execute tools, modify data, delete anything, or commit financial transactions. Despite being on a server with financial capabilities, this tool itself only reads/queries tool metadata.
From the tool's definition Tool name is 'discover' and description states it is used to 'Discover available tools based on natural language queries.' The action is searching/querying tool metadata to find available capabilities, with no side effects or modifications.
Documented attack patterns abuse exactly the kind of access discover gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Qveris Agent Toolkit, and nothing reaches the server without passing your rules. This is the rule we recommend for discover:
{
"version": "1",
"default": "deny",
"tools": {
"discover": {}
}
}discover is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Discover available tools based on natural language queries. It is categorised as a Read tool in the Qveris Agent Toolkit MCP Server, which means it retrieves data without modifying state.
Register the Qveris Agent Toolkit MCP server in PolicyLayer and add a rule for discover: 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 Qveris Agent Toolkit. Nothing to install.
discover 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 discover 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 discover. 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.
discover is provided by the Qveris Agent Toolkit MCP server (qverisai/qveris-agent-toolkit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
