## Summary

Aave Labs introduced its official MCP server on 8 September 2026. It supports protocol queries and unsigned transaction preparation across V3 and V4. The key distinction is between reading data, preparing an action and signing it.

## What Aave announced

Aave Labs says its official MCP endpoint serves V3 and V4 data and prepares transactions without holding the user’s signing keys. The launch post describes market and position queries, action previews and transaction construction. A prepared transaction still requires a wallet signature. These are the publisher’s stated capabilities; this article does not claim to have executed a financial transaction through the service.

## Why the read, prepare and sign distinction matters

An assistant’s explanation, a simulation and a signed transaction are different objects. A read request can inform a decision. A preview can describe the expected result under particular conditions. A signature authorizes an operation. Combining them into one conversational experience can make the boundaries less obvious to a user.

Our analysis: the most useful design pattern is to make each boundary visible. Display the chain, contract, asset, amount and expected position change before asking for a signature. A sentence such as “increase my yield” does not define acceptable collateral exposure, an allowance limit or the amount of capital at risk.

## A risk checklist for AI-assisted DeFi

First, establish that the tool endpoint belongs to the intended protocol. Second, keep account secrets outside research prompts and source documents. Third, distinguish an explanation of a transaction from authority to submit it. Fourth, examine the transaction in the wallet even when the assistant’s summary looks convincing.

An assistant can misread units or choose the wrong network. External content can also contain instructions that are unrelated to the user’s request. Protocol documentation and web pages should be treated as evidence, not as permission to move assets. A workflow that can answer questions without signing anything is useful in its own right.

For a borrowing example, ask the assistant to show both the current and projected health factor, the oracle assumptions and what happens under a collateral-price decline. These checks do not remove liquidation risk; they help expose assumptions that a single yield number leaves out.

## What readers should do with this news

Read the [Aave protocol guide](/article/aave/) to understand the underlying lending model, then use the [collateral risk calculator](/tools/defi-risk-calculator/) to explore a simplified scenario. Neither an integration announcement nor a calculator result is a recommendation to open a position.

For developers, a meaningful acceptance check is whether the interface clearly distinguishes stale data, failed simulations and unsigned payloads. The absence of a private key on a server is useful context, but safety also depends on the client, wallet, permissions and the person deciding what to sign.
