Agent-Ready: Content Monetization for Publishers

Turn your RSS feed or sitemap into a monetized MCP endpoint that AI agents discover and pay to query.

Non-technical? Start with the publisher guide on xpay.sh/docs/publishers for a visual walkthrough. This section covers the technical integration details.

How It Works

Paste your RSS/sitemap URL into the dashboard or call the Content Server API
Content is indexed into DynamoDB — titles, descriptions, full article markdown
MCP endpoint goes live at {your-slug}.mcp.xpay.sh
AI agents query your content via 3 MCP tools: search-content, get-article, list-recent
You earn 95% of every query payment (5% platform fee)

Architecture


Publisher RSS Feed → Content Server API (introspect + index)
                         ↓
                    DynamoDB (content index)
                         ↓
AI Agent → MCP Proxy → Content Server (MCP tools) → Return markdown
              ↓
        Billing: lock → deduct → log execution

The Content Server is an internal MCP server that the MCP Proxy routes to. Billing, auth, and execution logging are handled by the proxy — the content server only handles content retrieval.

Key Concepts

Concept	Description
Content Server	Lambda service that indexes RSS/sitemap content and serves it via MCP tools
MCP Proxy	Billing + routing layer at `*.mcp.xpay.sh` — handles auth, fund lock/deduct, logging
Content Index	DynamoDB table storing indexed articles per publisher (PK: serverId, SK: articleId)
Feed Refresh	Scheduled every 6 hours — detects new articles, updates index
upstreamType: content	Server record flag that routes MCP proxy to the content server instead of an external URL

API Endpoints

Endpoint	Method	Purpose
`/introspect`	POST	Validate and preview RSS/sitemap feed
`/index`	POST	Index feed content into DynamoDB
`/mcp`	POST	MCP JSON-RPC (tools/list, tools/call)
`/health`	GET	Health check
