What is a Model Context Protocol (MCP) Server?

An MCP server acts as a bridge, enabling AI models to access and interact with external data sources and tools. Specifically, the Substrate MCP Server allows AI models to interact with Substrate-based blockchains.

What are the key features of the Substrate MCP Server?

The server allows querying account balances and storage dynamically, listing pallets and their entries, fetching and filtering events and extrinsics, submitting and watching dynamic signed transactions, accessing system and block information, and making custom RPC calls to Substrate nodes.

What are some potential use cases for the Substrate MCP Server?

Potential use cases include AI-driven blockchain operations (integrating with LLMs for natural language interaction), custom dashboards and monitoring systems for Substrate blockchains, and AI agents to detect suspicious activity.

What is UBOS and how does the MCP Server integrate with it?

UBOS is a full-stack AI Agent Development Platform focused on bringing AI Agents to every business department. The Substrate MCP Server seamlessly integrates with the UBOS platform, enabling you to leverage its capabilities within your AI Agent workflows, enhance data access, simplify agent orchestration, and build customizable AI Agents.

How do I install and configure the Substrate MCP Server?

Clone the repository, build it using cargo build --release, create a .env file with configuration variables (RPC URL, signing keypair), obtain the runtime metadata file, and start the server using cargo run --release.

How can I integrate the Substrate MCP Server with Cursor?

Build the server, locate the binary, and add an entry for the server in your project’s .cursor/mcp.json file, specifying the command and any necessary arguments. Restart Cursor to allow it to detect and connect to your Substrate MCP server.

What tools are available in the Substrate MCP Server?

The server offers tools like query_balance, list_pallets, list_pallet_entries, dynamic_runtime_call, send_dynamic_signed_transaction, query_storage, get_latest_events, find_events, get_latest_block, get_block_by_hash, find_extrinsics, get_system_info, and custom_rpc for interacting with a Substrate blockchain.
