Permissions Found in Source Code

Found by scanning the linked source code. This listing connects to a hosted endpoint, so none of this runs on your machine: it describes what the server software does where it is hosted.

file_system

Applies to the server that hosts this plugin, not to your machine.

HTTP Network Access

Connects to external APIs or services over the internet.

How to Connect

Remote Plugin

No local installation needed. Your AI client connects to the remote endpoint directly.

Paid Agent APIs

Pay-per-call MCP APIs for AI agents. Every call is settled in USDC via the x402 protocol on Base — no accounts, no API keys, no subscriptions. Payment is the auth: your agent pays per call and gets the result.

Products

Service	What it does	MCP tool	Price	Status
AI Storefront Readiness Grader	Grades any storefront URL A–F across 20 weighted conversion-readiness checks (checkout friction, trust signals, mobile readiness, merchandising completeness) and returns the failing checks	`grade_storefront`	$1.00 / call	✅ LIVE
GEO Audit	Scores any URL's visibility to AI search engines (ChatGPT, Perplexity, Claude, Google AI Overviews) across 20 weighted checks and returns concrete fixes. Free tier: `audit_geo_lite`, rate-limited	`audit_geo`	$1.50 / call	✅ LIVE
A11y Audit	Accessibility lawsuit-risk scan: 20 weighted WCAG checks plus a lawsuit-risk level, framed as risk reduction for US businesses. Automated triage, not a certification	`audit_a11y`	$1.50 / call	Code complete — deploys with the next release
Feed Audit	Product-feed hygiene audit: flags the feed errors that get listings disapproved or suppressed before they cost sales	—	$1.00 / call	Code complete — deploys with the next release

Live endpoints

Service	MCP endpoint	HTTP endpoint
Storefront Grader	`POST https://grader-al6bxcngia-ue.a.run.app/mcp`	`POST https://grader-al6bxcngia-ue.a.run.app/grade`
GEO Audit	`POST https://geo-al6bxcngia-ue.a.run.app/mcp`	`POST https://geo-al6bxcngia-ue.a.run.app/geo` · free: `POST /geo-lite`

Both take { "url": "https://your-site.example" }. Source for every service lives in this repo (grader/, geo/, a11y/).

Add either live service to any MCP client as a remote server:

{
  "mcpServers": {
    "storefront-grader": { "url": "https://grader-al6bxcngia-ue.a.run.app/mcp" },
    "geo-audit": { "url": "https://geo-al6bxcngia-ue.a.run.app/mcp" }
  }
}

For agents: how payment works

Call the tool or endpoint without payment → you get an HTTP 402 with the full payment requirements (amount, network, pay-to address).
Pay in USDC on Base mainnet (eip155:8453) with any x402 client (@x402/fetch, the x402 Python package, CDP or PayAI wrappers) and retry with the payment proof.
The call runs and returns the result. No signup, no key management, no invoice.

Discovery documents (/.well-known/x402):

Both services also declare the Bazaar discovery extension (extensions.bazaar) in their 402 responses, so catalog crawlers can index the paid routes from the 402 alone.

Payment terms: x402 exact scheme · asset USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) · pay to 0xd702C8A8Ee30F6950A2a663010d12FC195D5348e · facilitator PayAI (https://facilitator.payai.network), with Coinbase CDP facilitator support built in.
