Spectra MCP Server vs Graph Aave MCP

list_aave_chains

Use this when the user asks which AAVE chains are supported, wants to pick a network, or needs to discover available AAVE deployments. Returns all supported chains with their subgraph IDs, protocol version (V2/V3), chain name, 30-day query volume, and key entities. Chains: Ethereum, Base, Arbitrum, Polygon, Optimism, Avalanche, Fantom (V3 + V2 legacy), plus AAVE Governance V3. Always call this first if chain is ambiguous.

get_aave_reserves

Use this when the user asks about AAVE lending markets, available assets, supply APY, borrow APY, TVL, utilization rate, collateral factors, or liquidation thresholds on a specific chain. Returns all active reserves sorted by total liquidity (TVL). RATE CONVERSION: liquidityRate and variableBorrowRate are in RAY units (1e27). Supply APY % = liquidityRate / 1e27 * 100. Borrow APY % = variableBorrowRate / 1e27 * 100. Amounts are in native token units — divide by 10^decimals for human-readable. Ideal for: 'What assets can I lend on Arbitrum?', 'What is USDC supply rate on Base?', 'Show me all AAVE V3 markets on Polygon'. SIZE: unfiltered this returns every active reserve (~28k tokens on Ethereum). Pass `symbols` for a named asset, or `compact: true` for rates only.

get_aave_reserve

Use this when the user asks about a specific AAVE asset in detail — e.g. 'Tell me everything about USDC on Ethereum AAVE', 'What are the WETH borrow parameters?', 'What is the liquidation threshold for WBTC collateral?'. Returns full reserve config: current rates, TVL, LTV, liquidation parameters, lifetime stats (total borrows/repayments/liquidations), and token addresses. RATE CONVERSION: divide liquidityRate / variableBorrowRate by 1e27 * 100 for APY %.

get_aave_user_position

Use this when the user asks about a wallet's AAVE position — 'What is my health factor?', 'What have I supplied to AAVE?', 'How much have I borrowed?', 'Am I at risk of liquidation?', 'Show me my collateral and debt on Arbitrum'. Returns all supplied assets (with aToken balances), all borrowed assets (variable + stable debt), collateral flags, and e-mode category. Health Factor ≈ sum(collateral_i * price_i * liqThreshold_i) / sum(debt_i * price_i). HF < 1.0 = liquidatable. Amounts in native token units — divide by 10^decimals.

simulate_health_factor

Use this when the user wants to simulate how a price change affects their AAVE health factor — 'What happens to my health factor if ETH drops 20%?', 'How much can WBTC fall before I get liquidated?', 'Simulate a 30% drop in my collateral asset'. Fetches the user's full position, computes current health factor, then recalculates it after applying the specified price change to the target asset. Health Factor < 1.0 means the position is liquidatable.

get_recent_borrows

Use this when the user asks about recent borrowing activity on AAVE — 'Who has been borrowing USDC on Ethereum?', 'Show me recent WETH borrows on Arbitrum', 'What has address 0x... borrowed recently?', 'Show borrow volume by asset'. Returns borrow events with: borrower address, asset, raw amount, borrow rate, rate mode (variable=2/stable=1), and timestamp. Divide amount by 10^decimals for human-readable value.

get_recent_supplies

Use this when the user asks about recent deposit/supply activity on AAVE — 'Who has been supplying ETH on Base?', 'Show me recent USDC deposits on Polygon', 'What has address 0x... deposited recently?'. V3 chains use the 'supply' entity; V2 chains use 'deposit' — handled automatically. Returns: supplier address, asset symbol, raw amount, and timestamp. Divide amount by 10^decimals for human-readable value.

get_aave_liquidations

Use this when the user asks about AAVE liquidation events — 'Show me recent liquidations on Ethereum', 'Has address 0x... been liquidated?', 'Who are the top liquidators on Arbitrum?', 'What collateral is being seized most?'. Returns: liquidator address, liquidated user, collateral asset seized, debt asset repaid, amounts, and timestamp. Liquidations occur when a user's health factor drops below 1.0.

get_aave_repays

Use this when the user asks about AAVE debt repayment activity — 'Show me recent repayments on Ethereum', 'Has address 0x... repaid any debt?', 'What assets are being repaid most on Arbitrum?', 'Show USDC repay history'. Returns repay events with: repayer address, asset, raw amount, and timestamp. Divide amount by 10^decimals for human-readable value.

get_aave_flash_loans

Use this when the user asks about AAVE flash loans — 'Show me recent flash loans on Ethereum', 'What assets are flash-loaned most?', 'How much in flash loan fees has AAVE earned?'. Returns: initiator address, asset borrowed, amount, fee paid (totalFee), and timestamp. Flash loans must be borrowed and repaid within a single transaction.

get_reserve_rate_history

Use this when the user asks about historical AAVE rates or TVL trends — 'How has USDC supply rate changed over time?', 'Show me ETH borrow rate history on Polygon', 'What was the utilization rate last week?'. Returns timestamped snapshots of: liquidityRate, variableBorrowRate, stableBorrowRate, utilizationRate, availableLiquidity, totalLiquidity, totalCurrentVariableDebt. Rates are in RAY units (divide by 1e27 * 100 for APY %). Get the reserve ID from get_aave_reserves (the 'id' field = underlyingAsset + poolAddress).

find_best_rates

Use this when the user asks 'Where should I supply USDC for the best yield?', 'Which chain has the lowest WETH borrow rate?', 'Compare AAVE rates across chains for USDC', 'Best AAVE lending rates for DAI'. Queries all AAVE lending deployments in parallel for the given asset, then ranks by APY. Excludes Fantom (incompatible Messari schema) and skips anomalous pools. Returns a ranked table with chain, supply APY, variable borrow APY, utilization, and approx available liquidity. Includes a _recommendation field with the best option.
