Part of the Graph Aave MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call get_reserve_rate_history to retrieve information from Graph Aave 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 get_reserve_rate_history 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.

Agents calling read-class tools like get_reserve_rate_history have been implicated in these attack patterns. Read the full case and prevention policy for each:
Other tools in the Read risk category across the catalogue. The same policy patterns (rate-limit, allow) apply to each.
Use this when the user asks about historical AAVE rates or TVL trends — 'How has USDC supply rate changed over time?', 'Show me ETH borrow rate history on Polygon', 'What was the utilization rate last week?'. Returns timestamped snapshots of: liquidityRate, variableBorrowRate, stableBorrowRate, utilizationRate, availableLiquidity, totalLiquidity, totalCurrentVariableDebt. Rates are in RAY units (divide by 1e27 * 100 for APY %). Get the reserve ID from get_aave_reserves (the 'id' field = underlyingAsset + poolAddress).. It is categorised as a Read tool in the Graph Aave MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for get_reserve_rate_history. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Graph Aave MCP server.
get_reserve_rate_history 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 get_reserve_rate_history rule in your Intercept 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 Intercept policy for get_reserve_rate_history. 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.
get_reserve_rate_history is provided by the Graph Aave MCP server (graph-aave-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
