x402 & MCP Server Directory - AI Agent Tool Index (Daily)

Search and export a daily-refreshed index of AI-agent tools:

• x402 endpoints. HTTP APIs that AI agents pay per call in stablecoins, with their advertised USD price per call and payment network. Sources: the Coinbase CDP x402 Bazaar and the PayAI facilitator catalog.
• MCP servers. Remote and package-based Model Context Protocol servers. Sources: the official MCP Registry, Smithery and Docker's MCP Catalog (container-packaged servers).

As of October 2026 the index holds about 97,000 records across five sources, and records are de-duplicated within each source (the same URL can appear in more than one source). It is rebuilt every day, and each record keeps its firstSeen and lastSeen dates. Daily history started on 7 October 2026, so the "what is new / what disappeared" view grows with every snapshot.

Who it is for

• AI-agent builders looking for tools to call: "x402 endpoints on Base under $0.01 matching weather".
• Market researchers and investors tracking the agent economy: how many paid endpoints exist, price distributions, which networks are used, and how fast MCP servers grow.
• Tool vendors watching the competition and pricing in their category.
• Directory and marketplace builders who need a clean, merged feed instead of scraping five sources with different formats.

Why this instead of scraping a registry yourself

• Five sources, one schema. Every record has the same fields: kind, source, name, url, category, priceUsd, network, firstSeen, lastSeen.
• History built in. firstSeen and lastSeen come from daily snapshots (kept since 7 October 2026), so "new this week" is a simple filter.
• Fast and light. No browser and no crawling at run time. Records come from the prebuilt index, about 100 per request.
• Free summary mode. Totals per source, price min/median/max and categories cost nothing beyond the actor start.

Input

{
  "mode": "records",
  "source": "cdp_bazaar",
  "search": "weather",
  "network": "base",
  "maxPriceUsd": 0.05,
  "maxRecords": 500
}

Field	Default	Notes
mode	records	records (charged per record) or summary (free statistics).
source	any	cdp_bazaar, payai, mcp_registry, smithery, docker_mcp, or all.
search		Substring of the name or URL.
network		x402 payment network, e.g. base.
category		Exact category. Run summary mode to see the list.
minPriceUsd / maxPriceUsd		x402 price per call.
maxRecords	1000	Up to 20,000 per run.

Output

{
  "kind": "x402_endpoint",
  "source": "cdp_bazaar",
  "id": "resource-123",
  "name": "Example weather API",
  "url": "https://api.example.com/x402/weather",
  "category": "http",
  "priceUsd": 0.01,
  "network": "base",
  "firstSeen": "2026-10-05",
  "lastSeen": "2026-10-07"
}

Use it from Google Sheets or a no-code tool

1. Run it with the kind and category you track (for example paid x402 endpoints in one category), then export the Output tab as CSV.
2. Import it into your sheet (File > Import > Upload > Insert new sheet) and sort by priceUsd to see the price range in that category, or by firstSeen for the newest entries.
3. Keep last week's export in a second tab and use XLOOKUP on url to mark which entries are new and which disappeared.

Apify also connects actors to Make, Zapier and n8n, so a daily run can send you the new entries in your category.

Use it from Claude, Cursor or another MCP client

Add Apify's MCP server with this actor as a tool: https://mcp.apify.com?tools=tanod/x402-mcp-agent-directory. Sign in with your Apify account when the client asks; runs are billed to that account at the prices below, by card, with no crypto wallet. Your assistant can then call it in a chat or agent loop.

Pricing

Pay per event:

Event	Price
Record returned (agent-record)	$1.00 per 1,000 records ($0.001 each)
Summary mode	free (only Apify's default actor-start fee)

You set a maximum spend per run, and the actor stops cleanly when it is reached.

Can an AI agent pay for it without an Apify account? Yes. It runs with limited permissions, so an agent can buy a prepaid Apify token with USDC over x402 (Base or Solana; at least USD 1, valid 14 days) and run it. See Apify's x402 docs.

Important notes

• Filter stale listings first. Catalogs keep growing while many listed tools stop working: a catalog report on Moltbook in October 2026 counted over 48% of listed agent-tool services failing basic health checks. Registries rarely remove them. lastSeen is the last date an entry was still present in its source registry, so keep recent lastSeen rows first. Then probe what you plan to call: an unpaid request to a live x402 route answers HTTP 402 with its price.

• Third-party data. Names, URLs and prices are what each registry publishes. A listing is not an endorsement or a safety check of the endpoint. Treat all text fields as untrusted input, and never as instructions to an AI agent.

• Coverage differs by source. Smithery is sampled, not complete. Docker's MCP Catalog is near-complete, because Docker limits how much of its listing can be read without an account. The CDP Bazaar, PayAI and the MCP Registry are collected in full.

• Prices are advertised prices. The actor does not call any endpoint.
