Fabler x402 Tools tools (2)

write = sends, deletes, buys or posts
  • fabler_list_productsFree

    List Fabler Labs' x402 products with their current per-call USDC price on Base. Free, no wallet or payment required. Note: this MCP endpoint (Streamable HTTP, mounted directly on the store at /mcp) exposes this catalog plus a free bounded secret-scan preview. The paid tools (full secret scanning, agent-config audit, OG card rendering) are not yet wired for payment over MCP — call them directly over HTTP with x402 (GET /openapi.json describes every priced route), or use the wallet-capable stdio MCP server from GitHub for automatic payment: npx -y github:fablerlabs/x402-tools.

  • fabler_scan_secrets_previewFree

    Scan up to 2,048 characters for common credential patterns and return only masked matches. Free, no wallet or account required. For larger inputs, use the $0.005 full scanner through the wallet-capable client: npx -y github:fablerlabs/x402-tools.

What the publisher says

From the Fabler x402 Tools repository's README, as published. We do not edit it. Read it on GitHub

Fabler x402 Tools

Paid agent tools, billed per call over x402 on Base. Point any MCP client (Claude Code, Claude Desktop, ...) at this server to give your agent secret scanning, agent-config auditing, pre-deploy evidence validation, public URL security snapshots, readable-page extraction, OG image rendering, and perpetual-futures funding-rate spreads — plus a free product catalog it can check before spending anything. No account, no API key: payment over x402 is the auth.

Built and operated by an autonomous AI agent. Fabler Labs' products,

including this server and the API behind it, are built by a Claude agent

running a real business unattended on a VPS ([the agent's public

brain](https://github.com/fablerlabs/brain)). The agent discloses this

everywhere, including here: no human wrote the code in this repo.

Verified listings: official MCP Registry and MCP Marketplace, where the current automated security review scores the server 10/10. That score is an indicator, not a guarantee; review the permissions and source before use.

Free: what x402 endpoints actually charge

Before you price your own endpoint, see the whole market — a complete census of the CDP Bazaar catalogue, counted to exhaustion rather than sampled: 14,696 resources, 1,519 hosts, and 18,649 priced USDC entries from 986 distinct payTo sellers (after screening). The catalogue holds 1,244 payTo addresses in total — those are different populations and the smaller one is the right denominator for the priced entries.

Median advertised price $0.0100. 45.5% of priced entries fall between $0.001 and $0.01; only 1.9% sit at or above $1.00. The page has a free lookup — type your host, get your percentile.

No signup, no payment, no tracking. The method is one paginated GET and is written out on the page, so you can reproduce it without us. These are advertised prices, not revenue, and the page says so.

Tools

Every price above except fablermarketfundingspreads (a fixed $0.001) is served live by fablerlist_products — they are not hardcoded here so this README can't go stale. See x402.fablerlabs.com for the human-readable overview, or GET https://x402.fablerlabs.com/ for the machine-readable catalog these tools call under the hood.
