@initia/mcp

MCP server and CLI for the Initia blockchain ecosystem. Tools for querying chain state, managing assets, and executing transactions across Initia L1 and L2 rollups (MiniEVM, MiniMove, MiniWasm).

Two interfaces, one codebase:

• @initia/mcp — MCP server (stdio transport, for Claude Desktop / LLM agents)
• initctl — CLI (for humans and scripts)

Quick Start

npm install
npm run build

CLI (initctl)

# Global install
npm install -g .
initctl chain list

# Or run directly without global install
node dist/cli.js chain list

# Or via npx (after npm install)
npx initctl chain list

Environment Variables

| Variable | Required | Default | Description | |---|---|---|---| | INITIA_KEY | No | — | Mnemonic (12/24 words), hex private key (0x...), or "ledger" | | INITIA_KEY_INDEX | No | 0 | HD derivation index (for mnemonic/ledger) | | INITIA_LEDGER_APP | No | ethereum | Ledger app: ethereum or cosmos | | INITIA_NETWORK | No | mainnet | mainnet or testnet | | AUTO_CONFIRM | No | false | Skip confirmation for mutations (MCP only) | | INITIA_LOG_LEVEL | No | info | debug, info, warn, error | | INITIA_USE_SCAN_API | No | false | Use Scan API for enhanced chain data |

Without a signer key, read-only tools still work. Mutation tools return SIGNER_REQUIRED.

Tools are registered once in a transport-agnostic ToolRegistry. The MCP and CLI adapters consume the same registry independently — adding a tool to a *.ts file automatically exposes it in both interfaces.

Smart Defaults

• Validator by name: Tools accepting a validator address also accept the moniker name (case-insensitive, auto-resolved)
• "me" address: Address parameters accept "me", "self", "my", or "signer" to resolve to the configured signer
• VM guard: Contract tools enforce VM compatibility — calling move_view on a MiniEVM chain returns a WRONG_VM error with suggested alternatives

Development

npm run dev          # Run MCP server with tsx (hot reload)
npm test             # Unit + integration tests
npm run test:smoke   # E2E tests against testnet
npm run lint         # ESLint + tsc --noEmit
