The MantraChain MCP Server is a versatile tool for interacting with the MantraChain blockchain through the Model Context Protocol (MCP). It offers comprehensive functionality including:
Token Management: Send tokens (
bank-send
), query account balances (get-balance
)Staking Operations: Delegate/undelegate tokens, claim rewards, query validator and delegation information
Network Operations: Fetch account details, block information, execute custom queries
IBC Operations: Transfer tokens across chains
Smart Contract Interactions: Query and execute smart contract functions
DEX Functionality: View liquidity pools, find swap routes, simulate and execute token swaps with slippage protection
Transaction Management: Sign and broadcast arbitrary transactions
The server supports both stdio
and HTTP+SSE
transport modes for flexible integration with various applications.
Provides OpenAPI/Swagger specifications for different networks through the openapi resource, allowing developers to explore and understand the available blockchain API endpoints.

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
get-balance: Get balance of an address (defaults to your own address if none provided)
Staking Operations
delegate: Delegate/Stake tokens to a validator
undelegate: Undelegate/Unstake tokens from a validator
claim-rewards: Claim rewards for a specific validator
get-validators: Get all validators
get-delegations: Get current staking information for an address
get-available-rewards: Get all available rewards for an address
Network Operations
get-account-info: Get current account information
get-block-info: Get block information
query-network: Execute a generic network query against chain APIs
IBC Operations
ibc-transfer: Send tokens via IBC transfer
Smart Contract Operations
contract-query: Query a smart contract by executing a read-only function
contract-execute: Execute a function on a smart contract that changes state
DEX Operations
dex-get-pools: Get all available liquidity pools from the DEX
dex-find-routes: Find available swap routes between two tokens
dex-simulate-swap: Simulate a token swap to get expected outcome without executing it
dex-swap: Execute a token swap on the DEX with slippage protection
Transaction Operations
sign-and-broadcast: Sign and broadcast a generic transaction
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:
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@latestHTTP+SSE Mode: Runs an HTTP server on port 3000, communicating via Server-Sent Events (SSE). Activate this mode using the
-r
flag or the dedicated npm scripts.# Using installed package mantrachain-mcp -r # Using npx export MNEMONIC="YOUR_MNEMONIC" export CUSTOM_NETWORKS="YOUR_CUSTOM_NETWORKS_JSON" npx -y mantrachain-mcp@latest -- -rWhen running in HTTP mode, the server listens on:
GET /sse
: Establishes the SSE connection.POST /messages?sessionId=<id>
: Receives client requests.
MCP Configuration
Installing via Smithery
To install MantraChain MCP Server for Claude Desktop automatically via Smithery:
To integrate with MCP client applications, add the server configuration to your MCP client configuration file:
Connecting remote MCP server in cline:
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.
Then, you can use the following configuration:
Environment Variables
MNEMONIC: Required. The mnemonic seed phrase for the wallet to use.
CUSTOM_NETWORKS: Optional. JSON string containing additional network configurations.
hybrid server
The server is able to function both locally and remotely, depending on the configuration or use case.
Tools
