Provides target profiles and one-shot payment routes for agents using Coinbase AgentKit and CDP, including failure mode handling and x402 payments via USDC on Base.
Provides target profiles and one-shot routes for agents built with CrewAI, enabling payment and verification through the Second Eyes substrate.
Provides target profiles and one-shot routes for LangGraph agents, integrating payment and verification for wallet-equipped agents.
Provides target profiles and one-shot routes for agents using OpenAI SDK with wallets, supporting payment and deterministic verdicts.
Accepts payments via Stripe ACP (Automated Clearing Payments) as a human or low-trust agent checkout rail for accessing one-shot routes.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Second Eyes MCP help me with schema repair"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.

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.

Identity / Reputation | ERC-8004 | Open registry — anyone queryable |
Payments | x402 (USDC / Base) | Default machine rail — open HTTP 402, no allowlist |

Transport | A2A / MCP | Existing |

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

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.
Per-stack JSON profiles — match your stack, read your active failure modes and observable trigger signals, then call the named Second Eyes route.
