Installation

npm install @manifest-network/manifest-mcp-chain

Tools

| Tool | Description | |------|-------------| | get_account_info | Get the address of the configured wallet | | cosmos_query | Execute any Cosmos SDK query (bank, staking, gov, etc.) | | cosmos_tx | Sign and broadcast any Cosmos SDK transaction | | cosmos_estimate_fee | Estimate gas and fee for a transaction without broadcasting | | list_modules | List all available query and transaction modules | | list_module_subcommands | List subcommands for a specific module | | request_faucet | Request testnet tokens from the faucet — only registered when a faucet URL is configured (CLI: set MANIFEST_FAUCET_URL; library: pass the faucetUrl constructor option) |
