How to Set Up and Use Klever Blockchain
Klever Blockchain MCP Server connects AI assistants to the Klever blockchain ecosystem, enabling smart contract development, on-chain data exploration, account and asset queries, and deployment tooling through natural language. It exposes a knowledge base of Klever contract patterns, storage mappers, event handling rules, and best practices, allowing developers to ask questions like 'How do I emit events correctly?' and get accurate, blockchain-specific answers. The server can run locally via stdio for full read/write access, or connect to the public hosted endpoint at mcp.klever.org for read-only exploration without any local setup.
Prerequisites
- Node.js 18 or higher and pnpm (for local setup), or just npx for the hosted mode
- A Klever blockchain account if deploying or transacting
- An MCP-compatible client such as Claude Desktop or Claude Code
- Redis (optional) if using Redis-backed storage instead of in-memory
Connect to the public hosted server (quickest path)
Point your MCP client at the public Klever MCP endpoint. No local installation required; the server runs in read-only mode.
claude mcp add -t http klever-vm https://mcp.klever.org/mcpOr install locally via npx
For full read/write access including contract initialization and helper script generation, run the server locally.
npx -y @klever/mcp-serverConfigure environment variables for local mode
Copy .env.example to .env and set at minimum the MODE and optional REDIS_URL if you want Redis-backed storage instead of in-memory.
MODE=mcp
STORAGE_TYPE=memory
PORT=3000Add to MCP client configuration
Add the Klever MCP server to your claude_desktop_config.json for automatic startup.
Initialize a Klever smart contract project
Once connected, ask the assistant to scaffold a new Klever contract project. The server uses the init_klever_project tool to generate the directory structure.
Klever Blockchain Examples
Client configuration
Add the Klever MCP server to claude_desktop_config.json using the public hosted endpoint or local npx command.

}Prompts to try
Use these prompts to explore Klever blockchain development and query on-chain data.
- "What storage mapper should I use for a token balance mapping in Klever?"
- "How do I emit events correctly in a Klever smart contract?"
- "How do I deploy and upgrade my Klever contract?"
- "Check my contract against Klever security best practices"
- "I'm getting a managed type API error — what am I doing wrong?"Troubleshooting Klever Blockchain
The local server starts but returns no knowledge base results
The public server has pre-loaded Klever knowledge. For local mode, ensure contexts have been ingested via the add_context tool or by running the batch ingest API before querying.
Rate limit errors when using the public hosted server
The public server enforces 60 MCP requests/min per IP by default. Space out requests or run a local instance to remove rate limiting. Set RATE_LIMIT_MCP in your .env for local deployments.
npx -y @klever/mcp-server fails to start in MCP stdio mode
Set the MODE environment variable to 'mcp' before running. By default the server starts in HTTP API mode. Use: MODE=mcp npx -y @klever/mcp-server
