Bring Account Abstraction
to LangChain
Learn how to connect Biconomy (Account Abstraction) to LangChain and start using 3 AI agent tools in minutes. Fully managed, enterprise secure, and ready to use without writing a single line of code.
Compatible with every major AI agent and IDE
What is the Biconomy (Account Abstraction) MCP Server?
Connect your Biconomy developer account to any AI agent to streamline Web3 operations through Account Abstraction. This server enables agents to handle complex on-chain flows with ease.
What you can do
- Supertransaction Quotes — Generate optimized quotes for complex transaction flows, including gasless (sponsored) options using the
get_quotetool. - Transaction Execution — Submit signed payloads for execution on-chain via Biconomy's robust infrastructure using
execute_supertx. - Status Tracking — Monitor the real-time progress of your Supertransactions using the
get_explorer_statustool. - Flexible Account Modes — Full support for Smart Accounts, EOA, and EOA-7702 account modes.
How it works
- Subscribe to this server
- Enter your Biconomy API Key
- Start orchestrating Web3 intents from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Web3 Developers — Rapidly prototype and test complex transaction flows without manual script writing.
- dApp Operators — Automate maintenance tasks and user operations using natural language.
- DeFi Power Users — Execute multi-step transactions with optimized gas and simplified signing.

Frequently asked questions
How do I request a quote for a gasless (sponsored) transaction?
Use the get_quote tool and simply omit the feeToken parameter. Biconomy will analyze the flow and return a quote where the gas is sponsored.
What do I need to provide to the execute tool after getting a quote?
You must provide the full quotePayload to the execute_supertx tool. Ensure that the required signatures have been added to the payloadToSign fields within that object.
Can I check the status of a transaction that is currently processing?
Yes. Use the get_explorer_status tool with the supertxHash returned by the execution endpoint to track its real-time progress on the blockchain.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
