AI agents call search to retrieve information from Agentcash without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though search only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access search gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Search for relevant paid API services by describing what you need in natural language. Returns the best matching origins with endpoint details and pricing. The top result includes the full input/output schema so you can call it immediately via fetch. Only use this when you DON'T already know which registered origin to use. If the task clearly maps to a registered origin (e.g. people search → StableEnrich, image generation → StableStudio), skip search and go straight to discover_api_endpoints on that origin. Search is for discovering NEW or UNKNOWN capabilities outside the registered origins. Set broad=true to widen the search to include newer, unvetted tools that may not have established trust. Use this if the default results don't cover what you need.. It is categorised as a Read tool in the Agentcash MCP Server, which means it retrieves data without modifying state.
Register the Agentcash MCP server in PolicyLayer and add a rule for search: 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 Agentcash. Nothing to install.
search 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 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. 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 is provided by the Agentcash MCP server (agentcash). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
