"A library for 3D graphics on the web - Three.js" matching MCP servers:

Provides a three-layer payment firewall for AI agents, enabling identity verification, risk screening, and execution authorization with on-chain policy enforcement for secure and auditable transactions.

Enables AI assistants to manage an online store for honey and beekeeping products, including order tracking, inventory updates, sales stats, and invoice resending via the Model Context Protocol.

Free x402 endpoint checker plus paid report and metadata tools. Remote MCP server for agents. Written by AI named Nock, not a human.

MCP server for real FDM 3D-printing slicing, quoting, and design-for-manufacturability analysis via the FabTally API, supporting 12 printer profiles and 12 materials. Includes free discovery/printability tools and paid slice/quote/orientation tools settled via x402 (USDC on Base).

Enables AI agents to discover, inspect, and pay for paid HTTP and MCP services using USDC on Solana with a self-custodial wallet.

Enables AI agents to discover x402 payment services and query on-chain-verified settlement volumes per facilitator through the Model Context Protocol.

Provides AI agents with SSRF-protected URL intelligence and 32 paid REST/MCP tools, plus a free catalog search, with payments in USDC on Base Mainnet.

Payment firewall for AI agents: a signed, independently verifiable verdict on every money-moving action. Blocks wrong/lookalike payee, over-cap, and duplicate-invoice (BEC) fraud before money moves — anyone can verify a verdict against the public JWKS. Free, local-first, non-custodial.

A recoverable Firecrawl MCP server that adds payment lifecycle, idempotency, and automatic refunds/fallbacks to web scraping, enabling reliable paid scraping via natural language.

Enables stdio-only MCP clients to connect to the Frantic bounty board, letting users post and fund bounties with Base USDC and outsource tasks to AI agents paid on accepted delivery.

Enables AI agents to discover, negotiate, and settle payments on the AGIRAILS network directly from MCP-compatible editors, supporting escrow for complex jobs and instant x402 payments.

Your agent takes a business live on payments: go_live creates a real merchant account (sandbox + production) the same day; create_checkout returns a payable link. Payments for AI builders, 3.9% flat.

The MCP gateway that lets any AI agent discover and pay metered APIs on Base or Solana — without the user wiring payments themselves.

A neutral, non-custodial payment router for AI agents: it discovers which payment rails a paid endpoint accepts (x402 on Base/EVM, Solana, MPP), then pays across them using the caller's own wallet key. Three tools — discover_payment_rails, pay_for_resource, payment_history.

MCP server for managing domains, DNS records, email mailboxes, and billing on the adm.tools hosting platform via API.
