Free catalog for Fabler's USDC-paid x402 agent tools on Base; no account or wallet required.
Most developer tooling work still happens through a UI a human drives. Fabler X402 Tools MCP server moves it into the conversation instead. Free catalog for Fabler's USDC-paid x402 agent tools on Base; no account or wallet required.
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.
github on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.
The server publishes 8 tools. What each one is for:
fabler_list_products — freefabler_scan_secrets — paidfabler_audit_agent_config — paidfabler_audit_pre_deploy — paidfabler_audit_url_security — paidfabler_scrape_web_page — paidfabler_render_og — paidfabler_market_funding_spreads — paid ($0.001 fixed)Configuration is passed through the environment: X402_BUYER_PRIVATE_KEY, X402_BASE_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Fabler X402 Tools's toolset — fabler_list_products, fabler_scan_secrets, fabler_audit_agent_config and 5 more — is a fair guide to whether it matches your workflow. It is maintained by com.fablerlabs; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
