AI agents use add_liquidity to create or modify resources in FINOPTIMA. 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 add_liquidity 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 FINOPTIMA.

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Every attack above starts with a tool call. PolicyLayer checks each one against your policy first, so add_liquidity only ever does what you allow.

Add liquidity to an AMM pool. You must provide both tokens in the correct ratio. Mints LP tokens in return.. It is categorised as a Write tool in the FINOPTIMA MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on add_liquidity? +

Register the FINOPTIMA MCP server in PolicyLayer and add a rule for add_liquidity: 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 FINOPTIMA. Nothing to install.

What risk level is add_liquidity? +

add_liquidity is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit add_liquidity? +

Yes. Add a rate_limit block to the add_liquidity 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.

How do I block add_liquidity completely? +

Set action: deny in the PolicyLayer policy for add_liquidity. 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.

What MCP server provides add_liquidity? +

add_liquidity is provided by the FINOPTIMA MCP server (finoptima). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every FINOPTIMA tool call.
