AI agents call ava_get_gas_prices to retrieve information from Ava Genesis 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 ava_get_gas_prices 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 ava_get_gas_prices 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.
Get real-time gas prices and total deployment cost estimates across all supported chains. Use this before deploying to pick the cheapest chain and avoid gas spikes. No API key required. Returns: gasPrice (gwei), estimatedDeployGas, totalCostEth, totalCostUsd, and platformFeeUsd for each chain. Data is fetched live from each chain's RPC — prices reflect current mempool conditions. Cache TTL: 15 seconds. If a chain RPC is unreachable, that chain is omitted from the response. Base and BNB Chain consistently have the lowest fees; Ethereum mainnet the highest.. It is categorised as a Read tool in the Ava Genesis MCP Server, which means it retrieves data without modifying state.
Register the Ava Genesis MCP server in PolicyLayer and add a rule for ava_get_gas_prices: 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 Ava Genesis. Nothing to install.
ava_get_gas_prices 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 ava_get_gas_prices 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 ava_get_gas_prices. 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.
ava_get_gas_prices is provided by the Ava Genesis MCP server (https://avagenesis.com/api/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
