MCP server for declarative intent execution. Agents submit intents — transfers, swaps, multi-hop routes — and the engine resolves and executes them atomically.

Generates MCP servers from smart contract ABIs, enabling Claude to interact with any Ethereum contract via natural language commands.

Powers AI agents with indexed blockchain data from The Graph, enabling them to fetch subgraph schemas and execute GraphQL queries against blockchain data.

Dune MCP Server connects your AI assistant to Dune Analytics, the leading platform for blockchain data. Execute SQL queries across Ethereum, Solana, and 20+ chains to analyze DEX trades, token transfers, NFT sales, and wallet activity. Manage saved queries, upload custom datasets, and access curate

Facilitates interaction with Starknet blockchain via MCP by exposing various RPC methods, allowing users to query chain states, transaction details, and block information using natural language queries.

Enables AI agents to trade perpetual futures, manage wallets, transfer tokens, bridge cross-chain, and execute EVM transactions on Injective using natural language.

An MCP server for executing token swaps on the Solana blockchain using Jupiter's Ultra API, enabling users to fetch optimal swap orders and execute transactions with slippage control.
