MCP SERVERGive it a wallet address and get back what that wallet is actually doing on-chain — lending, liquidity, farming and staking positions, plus token balances, valued in the currency you want.
LABSCO SUMMARY
The tools are the same question at different widths, and picking the right width is most of the cost: the all-chains scan is the one that takes time and returns everything, while the by-chain and by-protocol calls answer a specific question quickly. The multi-currency valuation is worth knowing about — a portfolio priced in EUR or GBP rather than USD comes out of the same call, not a conversion afterwards. Everything is read-only, so this reports on a wallet rather than acting for it.
A read-only portfolio reader over the Datai API. Every call takes a wallet address and answers with its positions and balances across chains and protocols, so nothing has to be indexed on your side.
A Datai API key in DATAI_API_KEY — it is the only required setting, and usage bills to that account. It runs over stdio as npx -y datai-mcp-server. Chains are named by short code, eth, arb, matic, avax, bsc, base and op. Several optional settings shape the responses rather than the data: DATAI_LIMIT, DATAI_DEBUG_TRUNCATE for shortened output while developing, and DATAI_CONNECTION_TIMEOUT and DATAI_RESPONSE_TIMEOUT, which are generous by default because a full multi-chain scan takes real time. Read-only: nothing here signs or sends a transaction. MIT.
One command plus a key — npx -y datai-mcp-server@1.0.3, then supply credentials
USE CASES
Run the full scan across every supported chain and read what it holds and where, before deciding what is worth looking at closely.
Filter the wallet's positions to that protocol across all chains — the question risk assessment actually asks after an incident.
Pull positions for the specific networks you care about and read them side by side, rather than scanning everything.
Get the overall balance across all chains or for one chain, returned in several major currencies rather than USD alone.
List the holdings with amounts, USD values and token metadata, and read the protocol balances alongside them.
Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.
get_all_defi_positionsGet comprehensive DeFi positions for a wallet across ALL supported blockchain networks and protocols. Provides complete portfolio overview including lending, liquidity pools, yield farming, staking, and other DeFi activities across 10+ chains and 15+ protocols.
get_defi_balances_by_chainGet DeFi protocol balances for a wallet on a specific blockchain network. Provides aggregated balance information grouped by protocol for diversification analysis and risk assessment.
get_defi_by_chainGet DeFi positions for a wallet on a specific blockchain network. Provides detailed information about lending, liquidity pools, yield farming, and other DeFi activities on the specified chain.
get_defi_by_protocolGet DeFi positions for a wallet filtered by a specific protocol across all chains. Provides detailed analysis of exposure to a particular DeFi protocol for risk assessment and yield optimization.
get_defi_multi_chainsGet DeFi positions for a wallet across multiple specified blockchain networks. Allows targeted multi-chain analysis by selecting specific chains of interest for comparison and portfolio analysis.
get_overall_balance_all_cGet overall balance for a wallet across ALL supported blockchain networks in multiple currencies. Provides complete portfolio valuation including USD, EUR, AUD, and other major currencies for comprehensive wealth tracking.
get_overall_balance_by_chainGet comprehensive overall balance for a wallet on a specific blockchain network in multiple currencies (USD, EUR, AUD, GBP, JPY, CAD, CHF). Provides aggregated portfolio valuation across all assets held on the specified chain.
get_wallet_balances_by_chainGet token balances for a wallet on a specific blockchain network. Provides detailed information about all token holdings including amounts, USD values, and token metadata for portfolio analysis.
BEFORE YOU INSTALL
8 tools when we connected. All eight tools only read from Datai's API.
The documented client runs the server on your machine.
CONTEXT COST
Rated by the size of the 8 tool definitions that ride along on every turn, not by how many there are
INSTALLATION
npx -y datai-mcp-server@1.0.3{
"mcpServers": {
"datai-fastmcp-server": {
"command": "npx",
"args": [
"-y",
"datai-mcp-server@1.0.3"
],
"env": {
"DATAI_API_KEY": "<YOUR_DATAI_API_KEY>"
}
}
}
}<YOUR_DATAI_API_KEY> is your Datai API key from api.datai.network/auth. The other variables in the README block (DATAI_LIMIT, DATAI_DEBUG_TRUNCATE, timeouts, PORT, DEBUG) are optional and default to non-debug values; DATAI_DEBUG_TRUNCATE "true" truncates responses for testing.
