- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below

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.
# 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.
# 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:
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:
{
"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:
{
"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.
npm run build
Then, you can use the following configuration:
{
"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.
