AI agents call list_pools to retrieve information from Spectra 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 list_pools 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 list_pools 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.
List all active Spectra pools on a given chain. Returns a summary of each pool including: asset name, maturity, TVL, implied APY, LP APY, pool liquidity, pool reserves (IBT/PT amounts with ratio), IBT APR breakdown (organic vs incentive yield), maturity redemption value, points multipliers, and asset tags. Each pool is a Curve StableSwap-NG AMM pair of IBT (interest-bearing token) and PT (Principal Token). Implied APY is the fixed rate you lock in by buying PT at discount. LP APY is the yield from providing liquidity to the pool (fees + gauge emissions). Set include_expired=true to also show recently matured pools (if the API returns them). By default only active (non-expired) pools are shown. For multi-chain discovery, use get_best_fixed_yields (raw APY ranking) or scan_opportunities (capital-aware with price impact and looping analysis). Use get_pool_activity on a specific pool to see recent trading patterns.. It is categorised as a Read tool in the Spectra MCP Server, which means it retrieves data without modifying state.
Register the Spectra MCP server in PolicyLayer and add a rule for list_pools: 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 Spectra. Nothing to install.
list_pools 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 list_pools 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 list_pools. 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.
list_pools is provided by the Spectra MCP server (spectra-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
