Copy this message into a Claude chat. The AI checks your computer, tells you which file it will change, and waits for your OK every time.

Please install the MCP server Chainlens for Claude on this computer, in this order: 1) Check Node.js with node -v. If it is missing, tell me to install it from https://nodejs.org/en/download; do not install it yourself. 2) Use only this config (already checked by PopNx MCP): { "mcpServers": { "chainlens": { "command": "npx", "args": [ "-y", "@reneturcios/chainlens", "mcp" ] } } } 3) Tell me the full path of the file you will change, or the command you will run, and wait for my OK. 4) No key is needed. 5) Do what we agreed, then check that the Chainlens tools really show up.

Common questions

Is Chainlens safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 13 days ago, and the latest version (0.1.0) reached the registry 13 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js, Docker on your computer.

What can I use instead?

README from the maker

Open the README

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

chainlens

chainlens looks into EVM blockchains through Blockscout: what an address holds and has done, what is in a block or a transaction, which tokens and NFTs sit in a wallet, and what a verified contract's ABI and source say. Six chains are built in — Ethereum, Optimism, Gnosis, Polygon, Base, and Arbitrum One — and every answer comes from that chain's public Blockscout API v2 instance.

This package is a clean-room rebuild of the 16 tools documented in the README of the original Blockscout MCP server. The full documented set is covered; the wire mapping is described below, including the parts that are reconstructions.

How it talks to the service

No API key is required — public Blockscout instances are keyless:

# Optional: send a key as an x-api-key header

export BLOCKSCOUT_API_KEY="your key"

Optional: override the per-chain base URL for any chain

export BLOCKSCOUT_API_URL="https://eth.blockscout.com/api/v2"

The base URL is chosen per chain_id from a built-in map: 1 Ethereum, 10 Optimism, 100 Gnosis, 137 Polygon, 8453 Base, 42161 Arbitrum One. An unknown chain_id is an error naming the known chains (unless BLOCKSCOUT_API_URL is set, in which case the override wins for any chain).

Wire-format notes. The original server routes most data tools through its PRO gateway; this rebuild maps them onto the public Blockscout API v2 (/addresses/..., /blocks/..., /transactions/..., /smart-contracts/..., /search). A few shapings are documented reconstructions and first live-smoke checks:

ENS resolution uses mainnet /search?q= and picks the first result carrying an address.
read_contract POSTs {function_name, args, abi} to /smart-contracts/{address}/methods/read — the least-proven mapping.
cursor arguments are forwarded as a cursor query parameter; Blockscout v2 paging normally uses next_page_params, so cursor support is a drift risk.
age_from / age_to (and methods / token) filters are applied client-side over the first fetched page, not forwarded upstream.

Two tools never touch the network: __unlock_blockchain_analysis__ returns local guidance plus the chain list, and get_chains_list filters that list locally by name, chain id, or currency substring.

Install

npx @reneturcios/chainlens get_block_number '{"chain_id":"1"}'

Or run the container image:

docker run -i ghcr.io/cloudcorprecords/chainlens

The container defaults to the MCP server. Pass CLI arguments to use it as a CLI instead.

CLI

The CLI mirrors the tools: one subcommand per tool, taking its arguments as a single JSON object.

chainlens get_chains_list '{"query":"base"}'

chainlens get_address_info '{"chain_id":"1","address":"0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"}' chainlens get_transactions_by_address '{"chain_id":"1","address":"0x...","age_from":"2026-10-01T00:00:00Z","age_to":"2026-10-26T23:59:59Z"}' chainlens get_block_info '{"chain_id":"8453","number_or_hash":"latest"}' chainlens --version

Exit codes: 0 on success, 1 on an API or validation error (the error names the problem), 2 for usage errors.

MCP server

One bin serves both faces. The mcp subcommand starts a stdio MCP server:

npx -y @reneturcios/chainlens mcp

MCP client configuration:

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