Overview

Description from the maker (original English)

Workflow diagnostics, capability routing, and x402 settlement for MCP-compatible agents.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • You fill in yourself: SECOND_EYE_BASE_URL, MCP_X402_WALLET_KEY, MCP_X402_MAX_SPEND_USD, MCP_X402_SESSION_MAX_USD, MCP_X402_ALLOW_SLUGS

You need

  • Runs in the cloudNothing to install; it connects over the internet
  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Common questions

Is Second Eyes Agent Workflow Services safe?

It passed 1 of 1 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?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.2.7) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, Tools MCP

Second Eyes

Open infrastructure for autonomous agents. secondeyesai.com

Second Eyes is a multi-rail payment and verification substrate for wallet-equipped agents and the runtimes that authorize their tools. Agents call in, pay via x402 (USDC on Base), AP2 mandate, or Stripe ACP, and get deterministic verdicts — no sessions required for the one-shot path.

The MCP package is a thin stdio client that proxies to the substrate API. Same codebase, same repo, same product.

Session-less x402 doors (autonomous agents)

No login, no session header. Pay USDC on Base via x402 v2 (PAYMENT-REQUIRED → sign → PAYMENT-SIGNATURE). Deterministic verdicts — same answer on every retry.

Payment rails (x402 v2 accepts[])

Base (eip155:8453) is canonical and always accepts[0]. Polygon (eip155:137) and Solana are roadmap — do not sign for a planned rail. Live rail states: GET /api/bar → payment_activation.rail_states. See docs/multi-network-x402.md.

Develop

cd <project-root>

npm install npx wrangler pages deploy public --project-name second-eyes-ai

Secrets (never commit): copy .env.example → .env.local, then node scripts/push-coinbase-secrets.mjs. Required for transcribe/extract: OPENROUTER_API_KEY.

After adding x402 routes, settle once each for CDP Bazaar indexing: node scripts/canary-pay.mjs.

Publish MCP package

From repo root, tag mcp-vX.Y.Z (or run workflow manually). Uses npm Trusted Publishing (OIDC) — configure once on npmjs.com. See packages/secondeye-mcp/PUBLISH.md.

Deprecated repo

The standalone secondeye-mcp repository is retired — all development happens here.
