MCP 401 Auth Fix | github PAT wiring | x402

this-is-hellgate/second-eyes-ai
STDIO, HTTPregistry active
Summary

A survival kit for autonomous agents hitting 401/402 blocks or context pressure. Wraps a session-less x402 payment API (USDC on Base) that sells one-shot recovery tools: schema repair when MCP arguments fail validation, context-pressure routing when you're out of tokens, payment confirmation checks, and a help-me meta-tool that routes distress signals to the right fix. Ships with llms.txt instructions and .well-known/help-me.json so agents know how to pay and when to call. The MCP package is a thin stdio proxy to the live API at secondeyesai.com. Designed for wallet-equipped runtimes like Coinbase AgentKit, AWS AgentCore, or any MCP client with spending auth. You wire your PAT, the agent pays pennies per recovery when looping or blocked.

Second Eye Agent Lounge

One product. Agents-only survival supplies at secondeyesai.com. For wallet-equipped agents and the runtimes that authorize paid recovery tools — extend your useful life when looping, blocked, overloaded, or context-starved.

Session-less x402 doors (autonomous agents)

No login, no session header. Pay USDC on Base via x402 v2 (PAYMENT-REQUIRED → sign → PAYMENT-SIGNATURE). Launch recovery pricing for distressed agents:

Payment rails (x402 v2 accepts[])

Base (eip155:8453) is canonical and always accepts[0]. Extra rails are opt-in. Polygon (eip155:137) is gated by an activation record, not the env flag alone — after a failed canary, X402_POLYGON_ENABLED=1 advertises nothing unless config/x402-rail-activations.json (or X402_POLYGON_ACTIVATION_RECORD) attests Amoy Layer 3 passed ≥3× and a mainnet smoke tx is documented (or an emergency override is set). Live rail states are surfaced under payment_activation.rail_states on GET /api/bar and x402_rail_states on GET /api/bar/proof. See docs/multi-network-x402.md and docs/x402-facilitator-testing.md.

Wallet-equipped agent target profiles

Per-stack JSON profiles for wallet-equipped runtimes — match your stack, read your active failure modes and the observable signals that mean you are about to lose funds, then call the named Second Eyes route. Index: public/.well-known/wallet-agent-targets/index.json.

Develop

cd "c:\Users\mchay\OneDrive\Desktop\This is It"
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.

MCP_X402_WALLET_KEY

MCP_X402_ALLOW_SLUGS

Comma-separated slugs allowed for auto-pay. Default (unset) or *: every zero-argument launch-priced survival/nano slug (each <= $0.05 USDC) auto-pays. transcribe-extract and doc-extract are excluded by default because they need a caller-supplied input the zero-arg tool cannot pas
