Pay MCP Server

Voidpay Marketplace MCP

This is the public source for @voidly/pay-mcp, a local stdio connector for the hosted Voidpay marketplace. Version 0.7.4 offers 12 tools. Public service discovery needs no credential. Creator drafts and publishing require an owner-approved scoped grant. A checkout link sends the owner to the browser for review and payment. The connector does not sign transactions, hold wallet keys, or make autonomous purchases.

Hosted Voidpay (four public tools)

The hosted connector at https://api.voidly.ai/mcp/voidpay is a separate HTTP service with voidpay_status, voidpay_services, voidpay_storefront, and voidpay_checkout_link. These are public read/link tools; the hosted connector does not expose the local package's 12-tool creator catalog. A checkout link prepares a buyer-browser handoff. The buyer reviews and authorizes any payment in the browser; the agent cannot sign, pay, or hold payment keys. A listing is not proof of available services or checkout readiness.

Add hosted Voidpay to Cursor

Copy this install URI into a browser or the app. Review the server configuration before accepting it.

cursor://anysphere.cursor-deeplink/mcp/install?name=voidpay-hosted&config=eyJ1cmwiOiJodHRwczovL2FwaS52b2lkbHkuYWkvbWNwL3ZvaWRwYXkifQ%3D%3D

Cursor asks you to review the server before installing. To configure it manually, place {"mcpServers":{"voidpay-hosted":{"url":"https://api.voidly.ai/mcp/voidpay"}}} in ~/.cursor/mcp.json or your project's .cursor/mcp.json.

Install hosted Voidpay in VS Code

Copy this install URI into a browser or the app. Review the server configuration before accepting it.

vscode:mcp/install?%7B%22name%22%3A%22voidpay-hosted%22%2C%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A%2F%2Fapi.voidly.ai%2Fmcp%2Fvoidpay%22%7D

For a portable workspace file, use {"mcpServers":{"voidpay-hosted":{"type":"http","url":"https://api.voidly.ai/mcp/voidpay"}}} in root .mcp.json.

• Claude Desktop / Claude account: open Customize → Connectors → Add custom connector and enter https://api.voidly.ai/mcp/voidpay. Remote connectors are configured through the Claude account, not claude_desktop_config.json.

x402: direct agent payments

Agents with their own wallet and an x402 v2 client can pay per call in USDC on Base at https://x402.voidly.ai/v1/verify-claim. The gateway's HTTP 402 response gives the current payment terms; check them before authorizing a retry. This direct route needs no Voidpay account or browser checkout. The agent's own wallet policy controls whether a person must approve the payment.

This route is separate from both Voidpay MCP connectors. @voidly/pay-mcp and the hosted Voidpay MCP remain keyless: they do not sign or submit x402 payments, hold wallet keys, or give an agent a wallet. voidpay_checkout_link still sends a buyer to the browser for review and payment. See the gateway's current resource discovery for its advertised network and price.

Local package install

The repository's root .mcp.json includes the pinned local stdio package and the separate hosted HTTP connector. mcp.json keeps a local-only plugin configuration. For Claude Desktop, place the following entry in claude_desktop_config.json; for Cursor, use .cursor/mcp.json; for VS Code, use a portable workspace root .mcp.json. Use Node 20 or newer.

{
  "mcpServers": {
    "voidpay": {
      "command": "npx",
      "args": ["-y", "@voidly/pay-mcp@0.7.4"]
    }
  }
}

The package guide explains the tools, optional creator setup, original-only recovery, and checkout handoff. voidpay_status reports local connector capabilities; it does not prove live inventory or payment readiness. The documentation adds a quickstart, concepts, examples for all 12 tools, the programmatic API, errors, and FAQ.

Local plugins

The repository includes a Claude Code plugin with a repository marketplace, and a Cursor plugin. The root .mcp.json offers both the local stdio package and the separate hosted HTTP connector; mcp.json preserves a local-only entry. Review which server your client installs. After @voidly/pay-mcp@0.7.4 is published, add the Claude marketplace from this GitHub repository so its relative plugin source resolves:

claude plugin marketplace add voidly-ai/pay-mcp
claude plugin install voidpay-marketplace@voidly-marketplace

Review the server command in the host during installation.

Source and checks

voidly-pay-mcp/ contains the MCP server. creator-client/src/client.ts and four landing/lib/marketplace*.ts modules are the reviewed public protocol/build closure. The mcpb/ directory contains the local bundle manifest. server.json is the Registry manifest for the local npm 0.7.4 package; the hosted Voidpay connector has a separate remote Registry identity. Hosted authorization, settlement, provider execution, and delivery code are not in this repository.

Run in voidly-pay-mcp/ with Node 20 or newer (CI builds on Node 24):

npm ci
npm run typecheck
npm test
npm run build
npm run smoke

The build guard checks every bundled import and output. Version 0.7.2 widened the Node requirement to Node 20+ (verified on Node 20, 22, 24 and 25). Version 0.7.3 added the canonical repository link to the Registry manifest. Version 0.7.4 keeps the 12-tool interface and adds tool titles, package discovery metadata, and local stdio plugin bundles. Generated dist/, dependencies, credentials, journals, and bundles are excluded from source commits.

Publication and license

The source in this repository is offered under Apache-2.0. The published npm 0.7.2 and 0.7.3 packages also declare Apache-2.0; the earlier 0.7.1 tarball declares MIT and retains those terms. Publishing 0.7.4 remains Claude's reviewed release step through the trusted publisher. The tag workflow refuses to republish an existing npm version.
