QoreChain MCP

An MCP server and a CLI that give AI agents and developer tools read access to QoreChain: blocks, transactions, accounts, validators, staking tiers, the status of the hybrid secp256k1 + ML-DSA-87 (FIPS 204) signature, contract reads, simulation and fee estimates, and unsigned transfers for the user's own wallet to sign.

The server never signs, never holds keys and never broadcasts.

Package

What it is

@qorechain/mcp

MCP server: stdio (npx -y @qorechain/mcp) and Streamable HTTP (qorechain-mcp serve), plus Fetch API and AWS Lambda handlers for self-hosting

@qorechain/qore-cli

qore command line with --json output identical to the MCP tool output

qorechain-mcp (Python)

the same server for Python stacks (uvx qorechain-mcp)

Container image

ghcr.io/qorechain/qorechain-mcp, runs qorechain-mcp serve

Quickstart

Add the server to any MCP client that starts local servers:

{
  "mcpServers": {
    "qorechain": { "command": "npx", "args": ["-y", "@qorechain/mcp"] }
  }
}

Then ask your agent, for example: "Is transaction F642F59F...2152 on QoreChain testnet hybrid-signed, and does the ML-DSA-87 layer verify?" Step by step: docs/quickstart.md.

From a terminal:

npx -y @qorechain/qore-cli pq status F642F59F2A2FEDA2B3A61A3CF49F8B5F792D65985027997004FEBB22A6F42152
npx -y @qorechain/qore-cli account qor1... --network mainnet --json

Tools

Every tool takes an optional network: testnet (chain qorechain-diana, the default) or mainnet (chain qorechain-vladi). Full schemas: docs/tools.md.

Tool

What it returns

get_chain_info

chain ids, latest block, minimum gas price, sign-bytes version, protocol features, pending upgrade, active EVM precompiles

get_block

one block (or the latest): hash, time, proposer, transaction hashes

get_transaction

a transaction by native or EVM hash: status, fee, messages, signers, signature tier

get_address_info

balances, account state, staked amount, both address forms (qor1... and 0x...)

get_pq_status

for an address: registered ML-DSA-87 key, key type, proof of possession, EVM window; for a transaction: exactly one hybrid layer present, and whether it verifies against the signer's registered key

get_validators

validators by stake, voting power share, commission

get_staking_tiers

lock terms and bonuses, bonus pool, one holder's locks

search

detects a height, hash, address or validator and reads it

read_contract

EVM eth_call only, with optional ABI encoding and decoding

estimate_fee

simulated gas, suggested gas limit and fee (including the ML-DSA-87 layer)

simulate_tx

gas, balance changes and decoded refusals for an encoded transaction

prepare_transfer

an unsigned SignDoc for a transfer, with checks and warnings

get_token_holders

not available: needs an indexer the public endpoints do not provide

request_faucet

not available here: testnet QOR comes from the dashboard faucet (sign-in required)

The EVM precompiles 0x...0A01 (ML-DSA-87 verify) and 0x...0A02 (key status) are active on testnet only.

Errors carry a stable code: NOT_FOUND, INVALID_INPUT, UPSTREAM_UNAVAILABLE, NOT_AVAILABLE_ON_CHAIN, RATE_LIMITED, UNAUTHORIZED, INTERNAL_ERROR.
