AI agents use write_asset_manager_yield_claimer_cowswap to create or modify resources in Arcadia Finance. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call write_asset_manager_yield_claimer_cowswap repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Arcadia Finance.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

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 Write tool in the Arcadia Finance MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Arcadia Finance 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 Finance. Nothing to install.
write_asset_manager_yield_claimer_cowswap is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
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 Finance MCP server (https://mcp.arcadia.finance/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
