# Covalent MCP for AI Agents AI Agent Connect

> Covalent lets your AI agent query live and historical blockchain data across 100+ networks. It handles token balances, transaction logs, and NFT metadata for chains like Ethereum and Polygon. Instead of manually checking multiple block explorers, you can ask your agent to pull specific on-chain data points instantly.

## Description

Imagine you're trying to track a portfolio spread across a dozen different blockchains. Usually, that means jumping between different block explorers, copy-pasting wallet addresses, and squinting at different UI layouts to find out what's actually happening. This Connector changes that by giving your AI agent a direct line to Covalent's unified data. You can just ask for the total value of a wallet on Polygon or see the last few transfers on a specific contract. It pulls the raw data and summarizes it for you in plain English. Whether you're auditing a smart contract's history or looking for a specific NFT's metadata, the agent does the heavy lifting of navigating the chain. It’s one of the reasons why the Vinkius catalog is so effective for Web3 workflows; it turns a complex data retrieval task into a simple conversation. You get to stay in your flow without the friction of switching tabs or learning complex query languages. It's about getting the numbers you need without the headache of finding them yourself.

## Tools

### get_block_details
Retrieve block hashes, timestamps, and transaction counts for a specific height. Use this to check specific points in chain history.

### get_chains_status
Check the current sync status and block height lag for all supported networks. This helps you see if a chain is currently lagging.

### get_dex_pools
List liquidity pool addresses and volume metrics for a specific decentralized exchange. It provides a clear view of DEX liquidity.

### get_nft_balances
Find NFT contract names, token IDs, and metadata URLs for a wallet address. This pulls the actual details of an NFT collection.

### get_historical_portfolio
Retrieve daily balances and historical USD valuations for a specific wallet. Use this to see how an investment has performed over time.

### get_token_transfers
See historical sender, receiver addresses, and transfer values for a wallet. It provides a clear audit trail of token movements.

### get_transaction_details
Fetch raw log events and decoded gas consumption metrics for a specific hash. This is vital for deep-diving into smart contract behavior.

### get_transactions
Get a full history of transaction hashes and timestamps for a wallet. Use this to see every interaction a specific address has made.

### list_supported_chains
See all chain IDs and supported features like NFTs or DEX data. This shows you exactly what networks the agent can access.

### get_token_balances
Get current token balances and ticker symbols for a specific wallet on a chosen chain. This helps you see exactly what assets a wallet holds.

## Prompt Examples

**Prompt:** 
```
Show me the token balances for address 0x123... on eth-mainnet.
```

**Response:** 
```
I found 5 tokens for that address. Total value is approximately $1,250.

**Breakdown:**
* 0.5 ETH
* 500 USDC
* 1,200 MATIC

Would you like to see the historical portfolio value?
```

**Prompt:** 
```
List the last 10 transactions for address 0x123... on matic-mainnet.
```

**Response:** 
```
I've retrieved the last 10 transactions for that address on Matic. 

**Summary:**
* Most involve interactions with Uniswap and Aave.
* 2 transactions failed due to out-of-gas errors.

Should I provide details for a specific transaction?
```

**Prompt:** 
```
What are the NFT holdings for wallet 0x123... on eth-mainnet?
```

**Response:** 
```
This wallet holds 3 NFTs:

* **Bored Ape Yacht Club**
* **CryptoPunks**
* **Art Blocks** piece

Would you like to see the metadata or the last sale price for any of these?
```

## Capabilities

### Check wallet balances across multiple chains
Get current token balances and ticker symbols for a specific wallet on a chosen chain.

### Pull historical portfolio valuations
Retrieve daily balances and historical USD valuations for a specific wallet.

### Search for NFT metadata and images
Find NFT contract names, token IDs, and metadata URLs for a wallet address.

### Get raw transaction logs and gas costs
Fetch raw log events and decoded gas consumption metrics for a specific hash.

### Monitor real-time network sync status
Check the current sync status and block height lag for all supported networks.

### List liquidity pool data for DEXs
List liquidity pool addresses and volume metrics for a specific decentralized exchange.

## Use Cases

### Auditing a failed transaction
A developer asks the agent to look up a specific hash. The agent uses get_transaction_details to find the gas error and log events.

### Multi-chain portfolio tracking
An investor wants to know their total value on BSC. The agent uses get_token_balances and get_historical_portfolio to show a summary.

### NFT collection research
A collector wants to see what NFTs a specific wallet holds. The agent uses get_nft_balances to list names and metadata.

### DEX liquidity analysis
An analyst needs to see liquidity on a specific DEX. The agent uses get_dex_pools to pull volume and reserve data.

## Benefits

- Stop jumping between block explorers because you can query Ethereum, Polygon, and 100+ other chains in one place.
- Get instant portfolio summaries using get_historical_portfolio to see how your assets have moved over time.
- Simplify NFT tracking with get_nft_balances that pulls metadata and image links directly into your chat.
- Audit smart contracts faster by pulling raw logs and gas metrics with get_transaction_details.
- Monitor network health in real-time using get_chains_status to see if a chain is currently lagging or out of sync.
- Analyze DEX liquidity with get_dex_pools to see reserve amounts and volume metrics without manual searching.

## How It Works

The bottom line is you get instant access to unified blockchain data without leaving your chat interface.

1. Get your Covalent API key from your dashboard at covalenthq.com.
2. Connect the Covalent MCP to your AI client and provide the API key.
