# MantraChain MCP Server
[](https://smithery.ai/server/@allthatjazzleo/mantrachain-mcp)
A Model Context Protocol (MCP) server for interacting with MantraChain (Cosmos SDK) blockchain. This server provides tools for sending tokens, delegating to validators, querying balances, and more using the MCP protocol.
## Features
- Send tokens to other addresses (bank send)
- Delegate tokens to validators (staking)
- Query account balances
- Get validator information
- Sign and broadcast arbitrary transactions
- Configure mnemonic and network via environment variables
- Choose between Dukong testnet and Mainnet
- **Supports both stdio and HTTP+SSE transport modes**
## Available Tools
### Bank Operations
- **bank-send**: Send tokens to another address (supports multiple coins per transaction)
- **get-balance**: Get balance of an address (defaults to your own address if none provided)
- **get_evm_balance**: Get native token (OM) balance for an EVM address
- **get_token_balance**: Get ERC20 token balance for an address
- **get_nft_balance**: Get ERC721 NFT count for an address from a collection
- **get_erc1155_balance**: Get ERC1155 token balance for a specific token ID
- **get_address_from_mnemonic**: Get EVM address derived from mnemonic
### Staking Operations
- **delegate**: Delegate/Stake tokens to a validator

- **transfer_erc1155**: Transfer ERC1155 tokens to another address
- **transfer_token**: Transfer ERC20 tokens to an address
## Available Resources
- **networks://all**: JSON resource showing all available networks with their configuration
- **openapi://{networkName}**: OpenAPI/Swagger specification for the specified network
## Running the Server
The server can run in two modes:
1. **Stdio Mode (Default):** Communicates over standard input/output. This is the default mode when running the server directly or via `npx`.
```bash
# Using installed package
mantrachain-mcp
# Using npx
npx -y mantrachain-mcp@latest
```
2. **Streamable HTTP Mode:** Runs an HTTP server on port 3000, communicating via Server-Sent Events (SSE). Activate this mode using the `--http` flag or the dedicated npm scripts.
```bash
# Using installed package
mantrachain-mcp --http
# Using npx
export MNEMONIC="YOUR_MNEMONIC"
export CUSTOM_NETWORKS="YOUR_CUSTOM_NETWORKS_JSON"
npx -y mantrachain-mcp@latest -- --http
```
## MCP Configuration
### Installing via Smithery
To install MantraChain MCP Server for Claude Desktop automatically via [Smithery](https://smithery.ai/server/@allthatjazzleo/mantrachain-mcp):
```bash
npx -y @smithery/cli install @allthatjazzleo/mantrachain-mcp --client claude
```
### To integrate with MCP client applications, add the server configuration to your MCP client configuration file:
```json
{
"mcpServers": {
"mantrachain-mcp": {
"command": "npx",
"args": [
"-y",
"mantrachain-mcp@latest"
],
"env": {
"MNEMONIC": "YOUR_MNEMONIC",
"CUSTOM_NETWORKS": "{\"my-custom-net\":{\"rpcEndpoint\":\"https://rpc.custom-network.io\",\"apiEndpoint\":\"https://api.custom-network.io\",\"chainId\":\"my-custom-net-1\",\"prefix\":\"custom\",\"denom\":\"ucustom\",\"gasPrice\":\"0.01\",\"isMainnet\":false}}"
}
}
}
}
```
### Connecting remote MCP server in [cline](https://docs.cline.bot/mcp-servers/connecting-to-a-remote-server):
```json
{
"mcpServers": {
"mantrachain-mcp-sse": {
"url": "http://localhost:3000/sse",
"transportType": "sse"
}
}
}
```
### If you build the package locally instead of globally
After building the package, you can run it directly from the build directory. Make sure to replace `your_path` with the actual path to your build directory.
```bash
npm run build
```
Then, you can use the following configuration:
```json
{
"mcpServers": {
"mantrachain-mcp": {
"command": "node",
"args": [
"your_path/mantrachain-mcp/build/index.js"
],
"env": {
"MNEMONIC": "YOUR_MNEMONIC"
}
}
}
}
```
## Environment Variables
- **MNEMONIC**: Required. The mnemonic seed phrase for the wallet to use.
- **CUSTOM_NETWORKS**: Optional. JSON string containing additional network configurations.
