The Flow MCP server provides tools to interact with the Flow blockchain and retrieve various information:
Get the FLOW balance for a specific Flow address
Retrieve balances for all fungible tokens associated with a Flow address
Fetch COA account information for a Flow address
Obtain the source code of deployed contracts at specific addresses
Access detailed account information including balance and storage stats
Integration for code linting and formatting to maintain code quality in the MCP server implementation.
Integration with the Bun JavaScript runtime for optimal MCP server performance, used for development, testing, and running the server.
Offers type-safe tool definitions for Flow blockchain interactions, ensuring proper data validation and error handling.
Implements type-safe schema validation for Flow blockchain tools, ensuring proper data formatting and validation.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Flow MCP check my FLOW balance for address 0x1234567890abcdef"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
This monorepo contains a collection of Model Context Protocol (MCPs) for interacting with the Flow blockchain and FLOW-EVM environment.
This monorepo is split into two main packages:
packages/flow-mcp: Core tools for interacting with the native Flow blockchain. This includes functionalities for managing accounts, checking balances, and interacting with native contracts.
packages/flow-defi-mcp: A suite of tools focused on DeFi (Decentralized Finance) and EVM-compatible interactions on the Flow network. This includes tools for checking token prices, swapping tokens on decentralized exchanges, and interacting with ERC20 tokens.
Please refer to the README.md file within each package for more detailed information, including setup instructions and a list of available tools.

Scored across 5 tools
There is overlap between get_account_info and get_flow_balance, as account info includes balance. Additionally, get_token_balances may overlap with the balance portion of account info. However, the descriptions provide some distinction.
All tools follow the consistent verb_noun pattern with 'get_' prefix, making them predictable and easy to understand.
5 tools is well-scoped for a read-only Flow blockchain information server. Each tool addresses a distinct query need without being overwhelming.
The set covers essential read operations for Flow accounts (balance, tokens, contracts, COA). Minor gaps exist such as missing block info or non-fungible token queries, but core functionality is present.
