Encode args for yield claimer coupled with CowSwap. Claims LP fees, then swaps the claimed tokens to a target token via CowSwap batch auctions (MEV-protected).

AI agents call write.asset_manager.yield_claimer_cowswap to retrieve information from Arcadia 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 write.asset_manager.yield_claimer_cowswap 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 write.asset_manager.yield_claimer_cowswap 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.
Encode args for yield claimer coupled with CowSwap. Claims LP fees, then swaps the claimed tokens to a target token via CowSwap batch auctions (MEV-protected). For staked LPs, sell_tokens is the staking reward token list (e.g. [AERO_address]). For non-staked LPs, sell_tokens is all LP fee tokens except the buy_token — e.g. for a WETH/USDC LP claiming fees as USDC, use sell_tokens: [WETH_address], buy_token: USDC_address. Sets metadata on BOTH the CowSwapper and the Yield Claimer. Returns { asset_managers, statuses, datas } with 2 entries (cowswapper + yield_claimer). Base only. Combinable with other intent tools.. It is categorised as a Read tool in the Arcadia MCP Server, which means it retrieves data without modifying state.
Register the Arcadia MCP server in PolicyLayer and add a rule for write.asset_manager.yield_claimer_cowswap: 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 Arcadia. Nothing to install.
write.asset_manager.yield_claimer_cowswap 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 write.asset_manager.yield_claimer_cowswap 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 write.asset_manager.yield_claimer_cowswap. 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.
write.asset_manager.yield_claimer_cowswap is provided by the Arcadia MCP server (arcadia-finance/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
