Klever MCP

Overview

Klever's official MCP server gives coding agents tools to write and deploy Klever VM smart contracts, query accounts and assets, and inspect transactions directly from an MCP-aware client. Maintained by Klever (klever-io), with 32 GitHub stars and commits as recent as May 2026.

• query_context — Search the Klever VM knowledge base for smart contract development context. Returns structured JSON with matching entries, scores, and pagination. Use this for precise filtering by type or tags; use s
• get_context — Retrieve a single knowledge base entry by its unique ID. Returns the full entry including content, metadata, tags, and related context IDs. Use this after query_context or find_similar to get complete
• find_similar — Find knowledge base entries similar to a given entry by comparing tags and content. Returns related contexts ranked by similarity score. Useful for discovering related patterns, examples, or documenta
• get_knowledge_stats — Get summary statistics of the Klever VM knowledge base. Returns total entry count, counts broken down by context type (code_example, best_practice, security_tip, etc.), and a sample entry title for ea
• enhance_with_context — Augment a natural-language query with relevant Klever VM knowledge base context. Extracts Klever-specific keywords, finds matching entries, and returns the original query combined with relevant code e
• search_documentation — Search Klever VM documentation and knowledge base. Returns human-readable markdown with titles, descriptions, and code snippets. Optimized for "how do I..." questions. Use this instead of query_contex
• analyze_contract — Analyze Klever smart contract Rust source code for common issues. Checks for missing imports, missing #[klever_sc::contract] macro, missing endpoint annotations, payable handlers without call_value us
• get_balance — Get the KLV or KDA token balance for a Klever blockchain address. Returns the balance in the smallest unit (for KLV: 1 KLV = 1,000,000 units with 6 decimal places). Optionally specify an asset ID to q
• get_account — Get full account details for a Klever blockchain address including nonce, balance, frozen balance, allowance, and permissions. Use this when you need comprehensive account state beyond just the balanc
• get_asset_info — Get complete properties and configuration for any asset on the Klever blockchain (KLV, KFI, KDA tokens, NFT collections). Returns supply info, permissions (CanMint, CanBurn, etc.), roles, precision, a
• query_sc — Execute a read-only query against a Klever smart contract (VM view call). Returns the contract function result as base64-encoded return data. Arguments must be base64-encoded. Use this to read contrac
• get_transaction — Get transaction details by hash from the Klever blockchain. Returns sender, receiver, status, block info, contracts, and receipts. Uses the API proxy for indexed data.
• get_block — Get block information from the Klever blockchain by nonce (block number). If no nonce is provided, returns the latest block. Returns hash, timestamp, proposer, number of transactions, and other block
• list_validators — List active validators on the Klever blockchain network. Returns validator addresses, names, commission rates, delegation info, and staking amounts.
• init_klever_project — Scaffold a new Klever smart contract project using the SDK. Creates the Rust project structure via `ksc new` and generates automation scripts (build, deploy, upgrade, query, test, interact). Requires
• add_helper_scripts — Add build, deploy, upgrade, query, test, and interact automation scripts to an existing Klever smart contract project. Creates a scripts/ directory with bash scripts and updates .gitignore. Run this f

Answers a call

yes — get_knowledge_stats returned in 140 ms

Live probe verifies the interface responds — not what the tools do, their safety, or their output quality. The call is one read-only tool named by this server's own list (list_/get_/search_, no mutating verb anywhere in the name, no required arguments and none that look like a key, an address or an amount), asked once a day with no arguments. Not asked is not a failure.
