Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@manifest-network/manifest-mcp-node

Node.js CLI entry points for the Manifest MCP servers with stdio transport and encrypted keyfile wallet.

Provides five binaries:

  • manifest-mcp-chain -- Chain MCP server (6 tools, +1 optional request_faucet: queries, transactions, fee estimation, module discovery)
  • manifest-mcp-lease -- Lease MCP server (8 tools: credit balance, funding, lease queries, custom-domain claim/lookup, SKUs, providers)
  • manifest-mcp-fred -- Fred MCP server (12 tools, plus 3 resources & 3 prompts: catalog, deployment readiness, manifest preview, deployment, ready polling, status, logs, restart, update, restore, diagnostics, releases)
  • manifest-mcp-cosmwasm -- CosmWasm MCP server (2 tools: MFX-to-PWR rate query, token conversion)
  • manifest-mcp-agent -- Agent MCP server (5 orchestrated tools: 3 broadcasting tools — deploy, manage-domain, close-lease — drive MCP elicitation and require an elicitation-capable host; 2 read-only tools — lookup-domain, troubleshoot — run on any host)

Setup

Requires Node.js >= 22.19.0 (declared via engines).

# From the monorepo root
npm install
npm run build

Wallet setup

All five servers need a wallet to sign transactions. Choose one of the options below.

Option A -- Generate a new keyfile (recommended)

npx manifest-mcp-chain keygen

All CLIs share the same keyfile (~/.manifest/key.json), so any of the five commands works for keygen and import. You will be prompted for an encryption password. The keyfile is written with mode 0600.

Option B -- Import an existing mnemonic

npx manifest-mcp-chain import

You will be prompted for your mnemonic (any valid BIP-39 length: 12, 15, 18, 21, or 24 words) and an encryption password. The wallet is derived from the mnemonic, encrypted, and stored in the same keyfile location. The raw mnemonic is not retained.

Option C -- Mnemonic via environment variable (fallback)

Set COSMOS_MNEMONIC in your .env or shell environment. This is used only when no keyfile exists.

Wallet resolution order

  1. If the keyfile exists at the path specified by MANIFEST_KEY_FILE (default ~/.manifest/key.json), use it
  2. Otherwise, if COSMOS_MNEMONIC is set, use it
  3. Exit with an error if neither is available

MCP client integration

Claude Desktop

Add the following to your claude_desktop_config.json:

Replace the placeholder values below with your actual chain ID, RPC/REST endpoint, gas price, and keyfile password.

{
  "mcpServers": {
    "manifest-chain": {
      "command": "npx",
      "args": ["manifest-mcp-chain"],
      "env": {
        "COSMOS_CHAIN_ID": "your-chain-id",
        "COSMOS_RPC_URL": "https://your-rpc-endpoint/",
        "COSMOS_GAS_PRICE": "0.01umfx",
        "MANIFEST_KEY_PASSWORD": "your-keyfile-password"
      }
    },
    "manifest-lease": {
      "command": "npx",
      "args": ["manifest-mcp-lease"],
      "env": {
        "COSMOS_CHAIN_ID": "your-chain-id",
        "COSMOS_RPC_URL": "https://your-rpc-endpoint/",
        "COSMOS_GAS_PRICE": "0.01umfx",
        "MANIFEST_KEY_PASSWORD": "your-keyfile-password"
      }
    },
    "manifest-fred": {
      "command": "npx",
      "args": ["manifest-mcp-fred"],
      "env": {
        "COSMOS_CHAIN_ID": "your-chain-id",
        "COSMOS_RPC_URL": "https://your-rpc-endpoint/",
        "COSMOS_GAS_PRICE": "0.01umfx",
        "MANIFEST_KEY_PASSWORD": "your-keyfile-password"
      }
    },
    "manifest-cosmwasm": {
      "command": "npx",
      "args": ["manifest-mcp-cosmwasm"],
      "env": {
        "COSMOS_CHAIN_ID": "your-chain-id",
        "COSMOS_RPC_URL": "https://your-rpc-endpoint/",
        "COSMOS_GAS_PRICE": "0.01umfx",
        "MANIFEST_KEY_PASSWORD": "your-keyfile-password",
        "MANIFEST_CONVERTER_ADDRESS": "manifest1..."
      }
    }
  }
}

If you use a mnemonic instead of a keyfile, replace MANIFEST_KEY_PASSWORD with COSMOS_MNEMONIC.

Query-only mode (REST/LCD)

To use query-only mode without transaction signing, replace COSMOS_RPC_URL and COSMOS_GAS_PRICE with COSMOS_REST_URL:

{
  "mcpServers": {
    "manifest-chain": {
      "command": "npx",
      "args": ["manifest-mcp-chain"],
      "env": {
        "COSMOS_CHAIN_ID": "your-chain-id",
        "COSMOS_REST_URL": "https://your-rest-endpoint/",
        "MANIFEST_KEY_PASSWORD": "your-keyfile-password"
      }
    }
  }
}

A wallet is still required at startup even in query-only mode. Transaction tools will return an INVALID_CONFIG error.

Environment variables

| Variable | Required | Default | Description | |----------|----------|---------|-------------| | COSMOS_CHAIN_ID | Yes | -- | Chain ID (e.g. manifest-ledger-beta) | | COSMOS_RPC_URL | One of COSMOS_RPC_URL or COSMOS_REST_URL required | -- | RPC endpoint URL (HTTPS required; HTTP allowed for localhost) | | COSMOS_GAS_PRICE | Required when COSMOS_RPC_URL is set | -- | Gas price with denom (e.g. 0.01umfx) | | COSMOS_REST_URL | One of COSMOS_RPC_URL or COSMOS_REST_URL required | -- | LCD/REST endpoint URL for query-only mode | | COSMOS_GAS_MULTIPLIER | No | 1.5 | Gas simulation multiplier (must be >= 1) | | COSMOS_MAX_GAS | No | 50000000 | Absolute per-tx gas-limit ceiling; a broadcast whose ceil(simulate × multiplier) exceeds it aborts with GAS_LIMIT_EXCEEDED; -1 disables | | COSMOS_ADDRESS_PREFIX | No | manifest | Bech32 address prefix | | MANIFEST_KEY_FILE | No | ~/.manifest/key.json | Path to the keyfile (encrypted, or a plaintext mnemonic loaded with a warning) | | MANIFEST_KEY_PASSWORD | No | -- | Password to decrypt the keyfile | | COSMOS_MNEMONIC | No | -- | BIP-39 mnemonic (fallback when no keyfile exists) | | MANIFEST_FAUCET_URL | No | -- | Faucet URL (enables request_faucet tool on chain server) | | MANIFEST_CONVERTER_ADDRESS | Required for cosmwasm server | -- | CosmWasm converter contract address | | MANIFEST_FRED_FETCH_GUARDED | No (fred server) | 1 (default ON) | SSRF guard for provider/Fred HTTP. Accepts 1/true/yes/on and 0/false/no/off (case-insensitive) | | MANIFEST_AGENT_FETCH_GUARDED | No (agent server) | 1 (default ON) | SSRF guard for agent-core provider HTTP. Same parser as MANIFEST_FRED_FETCH_GUARDED | | MANIFEST_AGENT_DATA_DIR | No (agent server) | -- | Directory for persisted deploy manifests (chmoded to 0o700); when unset, persistence is skipped | | MANIFEST_CHAIN_DATA_FILE | No (agent server) | -- | Path to a chain-registry JSON ({ feeTokens: [...] }) for denom humanization (umfx → MFX) | | MANIFEST_AGENT_ELICIT_TIMEOUT_MS | No (agent server) | 600000 (10 min) | Per-elicitInput timeout in milliseconds | | LOG_LEVEL | No | warn | Log level: debug, info, warn, error, or silent |

Set COSMOS_RPC_URL + COSMOS_GAS_PRICE for full access (queries + transactions). Set COSMOS_REST_URL alone for query-only mode (LCD/REST). When both are set, COSMOS_REST_URL is preferred for queries.

COSMOS_CHAIN_ID and at least one endpoint URL are only required when starting an MCP server, not for keygen or import.
