Injective MCP Servers, Skill Guide

Model-Context-Protocol (MCP) servers facilitate discovery and expose tools, intended to be called by LLMs. This skill provides instructions on how to set up and use MCP servers that are important for Injective.

When to apply

• When you are searching for canonical information about Injective, use Injective Documentation MCP Server.
• When you are querying or transacting on Injective Mainnet or Testnet, use Injective MCP Server.
• When you are using full trading capabilities, including perpetual futures, spot transfers, cross-chain bridging, and raw EVM transactions, use Injective MCP Server.

Activities

Set up and run Injective Documentation MCP Server

Not applicable, as we provide a hosted MCP server for you. Simply connect to https://docs.injective.network/mcp, which exposes a streamable HTTP endpoint that most MCP clients are able to consume.

Use Injective Documentation MCP Server

Perform MCP tool calls:

• SearchInjectiveDocs - Searches official Injective documentation. Returns results including citations.

See: https://docs.injective.network/developers-ai/documentation-mcp.md

Set up and run Injective MCP Server

Installation:

git clone https://github.com/InjectiveLabs/mcp-server injective-mcp-server
cd injective-mcp-server
npm install && npm run build

Run manually:

INJECTIVE_NETWORK="mainnet" node ./dist/mcp/server.js

Run via Claude Code:

Edit ~/.claude/mcp.json or the MCP configuration within your project to include the following:

{
  "mcpServers": {
    "injective": {
      "command": "node",
      "args": ["/path/to/injective-mcp-server/dist/mcp/server.js"],
      "env": {
        "INJECTIVE_NETWORK": "mainnet"
      }
    }
  }
}

Use Injective MCP Server

Perform MCP tool calls:

• wallet_generate - Generate a new Injective wallet. Returns address + mnemonic (shown once).
• wallet_import - Import a wallet from a hex private key.
• wallet_list - List all wallets in the local keystore (addresses only - no keys).
• wallet_remove - Permanently delete a wallet from the keystore.
• market_list - List all active perpetual futures markets.
• market_price - Get the current oracle price for a market by symbol (e.g. BTC).
• account_balances - Get bank + subaccount balances. Supports all token types.
• account_positions - Get open perpetual positions with unrealized P&L.
• token_metadata - Look up symbol, decimals, and type for any denom.
• trade_open - Open a position with a market order (Cosmos signing).
• trade_close - Close an open position with a market order (Cosmos signing).
• trade_open_eip712 - Open a position using EIP-712 Ethereum signing (MetaMask-compatible keys).
• trade_close_eip712 - Close a position using EIP-712 Ethereum signing (MetaMask-compatible keys).
• trade_limit_open - Open a limit order.
• trade_limit_orders - List open limit orders.
• trade_limit_close - Cancel a limit order by orderHash.
• trade_limit_states - Query order states by order hash.
• transfer_send - Send tokens to another Injective address.
• subaccount_deposit - Deposit from bank balance into a trading subaccount.
• subaccount_withdraw - Withdraw from a trading subaccount back to bank balance.
• bridge_withdraw_to_eth - Withdraw to Ethereum via the Peggy bridge (~30 min, fee applies).
• bridge_debridge_quote - Get a deBridge DLN quote to any supported chain. Read-only.
• bridge_debridge_send - Bridge tokens from Injective to another chain via deBridge DLN.
• evm_broadcast - Broadcast a raw EVM transaction on Injective EVM.

Known Gotchas

Critical findings for anyone building on or extending the MCP server, or integrating with MetaMask.

EIP-712 Signing (MetaMask)

• Use V2, not V1. V1 (getEip712TypedData) uses non-standard domain types (verifyingContract: "cosmos", salt: "0" as strings). MetaMask's eth_signTypedData_v4 silently produces invalid signatures with V1. Always use getEip712TypedDataV2 + SIGN_EIP712_V2.
• Fee objects must match exactly. getEip712TypedDataV2() and createTransaction() must receive the exact same fee object. If one uses the SDK default and the other a custom fee, the chain reconstructs different typed data → hash mismatch → signature verification failure.
• evmChainId can be any EVM chain. Injective EIP-712 signing works regardless of which EVM chain MetaMask is connected to. Read chain ID from eth_chainId and pass to both the EIP-712 domain and createWeb3Extension.

SDK fromJSON Scaling

• MsgCreateDerivativeMarketOrder.fromJSON applies ×10^18 internally. It expects values in chain units (price/margin already ×10^6 for USDT markets), then appends 18 decimal places for protobuf. Pass: price = humanPrice × 10^6, margin = humanMargin × 10^6, quantity = humanQty (not scaled by quote decimals).

Margin Calculation

• Add 1–2% buffer above exact minimum. If margin == price × qty × initialMarginRatio exactly, the chain may reject due to rounding.
• Use max(oraclePrice, markPrice) for validation. The chain validates margin against the higher of oracle and mark price. Margin calculated from oracle alone may be insufficient if mark > oracle.
• stakeUsdt is margin, not notional. In web apps, the user's stake parameter is their margin. qty = stake × leverage / price, not notional / price.

Close Orders

• Use margin: '0' for reduce-only. No separate isReduceOnly flag needed on Injective.
• Use 1% slippage for closes. 5% slippage can trigger "order price surpasses bankruptcy price" for low-leverage positions.

Subaccount Deposits

• Bank balance ≠ exchange subaccount balance. A MsgDeposit (or subaccount_deposit tool call) is required to move USDT from bank → subaccount before placing derivative orders. Always check subaccount balance and auto-deposit if needed.

Deployment (Express / Web Apps)

• Serve from the correct subdirectory. If server.js serves from dist/, deploy built files to dist/, not the project root.
• Set no-cache headers on HTML. Without Cache-Control: no-cache, no-store, must-revalidate on HTML responses, browsers serve stale JS bundles after deploys.
