Second Eyes Agent Workflow Services

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

Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

Environment variables

SECOND_EYE_BASE_URL Second Eyes service base URL
MCP_X402_WALLET_KEY EVM private key (0x…) for auto USDC payment on 402. SECURITY: MCP process can drain this wallet — use a dedicated low-balance payer.
MCP_X402_MAX_SPEND_USD Per-call spending cap (default 0.50)
MCP_X402_SESSION_MAX_USD Process lifetime spending cap (default 2.00)
MCP_X402_ALLOW_SLUGS Comma-separated capability slugs allowed for compatibility auto-pay. Default (unset) or * enables every zero-argument capability priced at or below $0.05 USDC. Input-requiring transcription and extraction routes remain excluded unless explicitly selected. Spending caps remain authoritative.

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.

Surface	Location
Live API + site	`/` — Cloudflare Pages (`wrangler pages deploy public`)
MCP npm package	`packages/secondeye-mcp` — `@secondeyes/mcp-unblock`
Agent entry	`GET https://secondeyesai.com/api/bar`
Agent instructions	`public/llms.txt` — how to pay, service catalog, one-shot routes
Help-me JSON packet	`public/.well-known/help-me.json` — machine-readable distress entry route
Agent card	`public/.well-known/agent-card.json`
Crawler policy	`public/robots.txt`

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

Protocol anchors

Layer	Protocol	Role
Identity / Reputation	ERC-8004	Open registry — anyone queryable
Payments	x402 (USDC / Base)	Default machine rail — open HTTP 402, no allowlist
Payments	AP2 + VDC mandates	Gates internal ephemeral spawn only
Payments	Stripe ACP	Human or low-trust agent checkout
Discovery	x402 Bazaar / CDP	Substrate endpoints registered publicly
Transport	A2A / MCP	Existing

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.

Door	Path	Price
help-me (canonical meta-tool — looping, schema mismatch, context pressure, crash, handoff failure, wallet/spend-policy, grounding risk, auth/tool/sandbox failure, payment uncertainty)	`/api/bar/x402/help-me`	$0.01
AWS AgentCore one-shot map	`/api/bar/x402/aws-agent-survival`	$0.01
`peril-router` (legacy alias of help-me)	`/api/bar/x402/peril-router`	$0.01
Schema repair	`/api/bar/x402/schema-repair`	$0.03
Context pressure (alias: token-pressure)	`/api/bar/x402/context-pressure`	$0.03
Payment confirmation check	`/api/bar/x402/payment-confirmation-check`	$0.01
Specialist one-shot routes	`/api/bar/x402/{slug}`	$0.01–$0.05
Transcribe (audio/video/PDF) + meaning	`/api/bar/x402/transcribe`	$0.05
Doc extract (invoice/contract/PDF)	`/api/bar/x402/extract`	$0.05
Bazaar index check	`/api/bar/x402/index-check`	$0.05
x402 format doctor	`/api/bar/x402/doctor`	$0.25

Full agent-facing docs: /llms.txt. Index new routes: node scripts/canary-pay.mjs.

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.

Wallet-equipped agent target profiles

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

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.
