Question 1

What is a Model Context Protocol (MCP) Server?

Accepted Answer

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.

Question 2

What are the key features of the Substrate MCP Server?

Accepted Answer

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.

Question 3

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

Accepted Answer

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.

Question 4

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

Accepted Answer

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.

Question 5

How do I install and configure the Substrate MCP Server?

Accepted Answer

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`.

Question 6

How can I integrate the Substrate MCP Server with Cursor?

Accepted Answer

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.

Question 7

What tools are available in the Substrate MCP Server?

Accepted Answer

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.
