AI agents use yield_deposit to initiate financial transactions through Agent Einstein — Autonomous Crypto Intelligence. Financial operations involve real money and are irreversible once processed. PolicyLayer blocks financial tools by default, requiring explicit human approval with transaction-level limits to prevent unauthorised spending.
yield_deposit moves real money. Without a policy, an autonomous agent could initiate transactions that drain accounts or exceed budgets. PolicyLayer blocks financial tools by default, requiring human-in-the-loop approval with configurable spending limits per transaction and per time window.
Financial tools involve real money. Block by default and require explicit human approval before enabling.

Yield Vault Deposit: Deposit tokens into an optimal DeFi yield vault via LI.FI Earn. Handles swap + bridge + deposit atomically across 60+ chains in a single transaction. Falls back to direct Aave V3 / Pendle adapters when LI.FI is unavailable. Returns signed transaction plan + approval data.. It is categorised as a Financial tool in the Agent Einstein — Autonomous Crypto Intelligence MCP Server, which means it involves financial transactions. Block by default and require explicit approval.
Register the Agent Einstein — Autonomous Crypto Intelligence MCP server in PolicyLayer and add a rule for yield_deposit: 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 Agent Einstein — Autonomous Crypto Intelligence. Nothing to install.
yield_deposit is a Financial tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the yield_deposit 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 yield_deposit. 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.
yield_deposit is provided by the Agent Einstein — Autonomous Crypto Intelligence MCP server (https://emc2ai.io/api/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
