Question 1

What is the Stellar MCP Server?

Accepted Answer

The Stellar MCP Server is an implementation of the Model Context Protocol (MCP) designed to allow AI agents and Large Language Models (LLMs) to interact with the Stellar blockchain. It provides a standardized interface for performing Stellar blockchain operations.

Question 2

What is MCP?

Accepted Answer

MCP stands for Model Context Protocol. It is an open protocol that standardizes how applications provide context to LLMs, enabling AI models to access and interact with external data sources and tools.

Question 3

Why use Stellar MCP?

Accepted Answer

Stellar MCP allows AI agents to directly access Stellar blockchain functionality, enabling them to create and manage Stellar accounts, fund accounts with testnet lumens, fetch account information and transaction history, sign and submit Soroban smart contract transactions, and interact with Passkey wallets.

Question 4

What are the key features of the Stellar MCP Server?

Accepted Answer

Key features include account management (creation, funding, details), transaction operations (viewing history, signing Soroban transactions, supporting various wallets), and smart contract integration (interaction, authorization handling).

Question 5

What are the prerequisites for installing the Stellar MCP Server?

Accepted Answer

The prerequisites include Node.js (v16 or higher), npm or yarn, and a Stellar testnet account for testing.

Question 6

How do I install the Stellar MCP Server?

Accepted Answer

You can install the server directly from npm or clone the repository from source and install dependencies using `npm install`.

Question 7

What environment variables are required to configure the server?

Accepted Answer

Required environment variables include `NETWORK_PASSPHRASE`, `RPC_URL`, `LAUNCHTUBE_URL`, `LAUNCHTUBE_JWT`, `MERCURY_URL`, `MERCURY_JWT`, `MERCURY_PROJECT_NAME`, `WALLET_WASM_HASH`, `AGENT_KEYPAIR_FILE_PATH`, and `USAGE_GUIDE_FILE_PATH`.

Question 8

How do I run the server?

Accepted Answer

After installing the dependencies and configuring the environment variables, you can run the server using `npm run build` followed by `node build/mcp-server.js`.

Question 9

How can I connect the MCP server to Claude Desktop?

Accepted Answer

Add a server configuration to your Claude Desktop config file (`~/Library/Application Support/Claude/claude_desktop_config.json`) with the appropriate command, arguments, and environment variables.

Question 10

What are some usage examples for the Stellar MCP Server?

Accepted Answer

Usage examples include creating a new Stellar account, funding an account with testnet lumens, fetching account information, and submitting a Soroban transaction.

Question 11

How does the `sign-and-submit-transaction` tool handle smart contract transactions?

Accepted Answer

The `sign-and-submit-transaction` tool accepts pre-assembled transaction XDRs from Soroban contract invocations, handles proper transaction signing, manages transaction submission, and provides detailed error handling. It supports both standard Stellar accounts and smart wallet implementations.

Question 12

What key components are included in the Stellar MCP Server?

Accepted Answer

Key components include the MCP Server (`mcp-server.ts`) which exposes Stellar blockchain functionality through MCP tools, and utilities (`utils.ts`) which provide helper functions for Passkey wallet integration, transaction signing, and resource file handling.

Question 13

How can I contribute to the project?

Accepted Answer

Contributions are welcome! Please feel free to submit a Pull Request in the GitHub repository.

Question 14

Where can I find support for the Stellar MCP Server?

Accepted Answer

For questions and support, please open an issue in the GitHub repository.

Question 15

How does the Stellar MCP server integrate with the UBOS Platform?

Accepted Answer

The Stellar MCP Server can be integrated with the UBOS platform to leverage additional functionalities, such as agent orchestration, data integration, and custom AI agent development. UBOS provides a comprehensive suite of tools for building, deploying, and managing AI agents, enhancing the capabilities of the Stellar MCP Server.
