Transport: Streamable HTTP
Runtime: Web executable
Trust: Verified

Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to x402broker.com, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Remote MCP gateway for browsing a catalog of API passes and credits, managing carts and checkouts, and retrieving order keys.

What you can do: Search and look up catalog products and API passes by keyword or identifier
Read product metadata, pricing and variant IDs
Search store policies and FAQs on privacy, refunds, terms and SLAs
Create, view, update and cancel shopping carts
Create, view, update, cancel and complete checkout sessions
Retrieve fulfilled order receipts and API pass keys
When to use it: Use it when an assistant needs to find and buy API passes or credits from this provider, compare pricing, or check refund and SLA terms before a purchase. It is a commerce flow, not a general-purpose tool router for arbitrary MCP servers.
Requirements: A remote streamable HTTP endpoint; no local package, environment variables or headers are declared. Checkout completion references payment rails (Base USDC x402 or Stripe MPP), so a payment method is presumably needed, though the input does not specify how it is supplied.

Before you install

Checkout tools create and finalize real purchases and settle payment via Base USDC x402 or Stripe MPP, which can spend money. Carts and checkouts can be created, changed and cancelled. Order lookups return API pass keys, which are credentials. The README describes a separate assurance service at a different host, not this gateway's endpoint.

Installation

In SourceWeft

Open X402-Broker Universal MCP Gateway & Multi-Agent Swarm Router in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.x402broker%2Fmcp-gateway/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Assay continuously probes remote MCP, A2A, and x402 endpoints to verify liveness, pin canonical SHA-256 tools/list schema hashes (detecting silent MCP Rug Pulls), and scan for prompt-injection tool poisoning before your agent pays or executes a tool.
