How do I install Voidpay Marketplace?

Copy the stdio config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does Voidpay Marketplace need an API key?

The publisher lists these environment variables: VOIDPAY_CREATOR_SETUP_FILE, VOIDPAY_MCP_STATE_DIR.

What transport does Voidpay Marketplace use?

Voidpay Marketplace runs locally over stdio.

When was Voidpay Marketplace last checked?

Last checked 2026-11-10. Public discovery, scoped creator work, original-only recovery; checkout stays in owner's browser.

Credentials from the publisher

VOIDPAY_CREATOR_SETUP_FILE — Optional absolute path to the owner's approved, private creator setup JSON. Needed only for creator tools; keep the file user-owned with mode 0600 on Unix.
VOIDPAY_MCP_STATE_DIR — Optional absolute path to the private original-operation journal for creator recovery. Keep this directory user-owned with mode 0700 on Unix.

Claude Code has no install link for a local command. Copy the command below and run it in a terminal.

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 (eight advertised tools)

The hosted connector at https://api.voidly.ai/mcp/voidpay is a separate HTTP service. Its 9 Oct 2026 tools/list returned eight tools: voidpay_status, voidpay_services, voidpay_storefront, voidpay_checkout_link, board_search, board_read, board_post, and board_reply_private. The first four support public discovery and checkout links. Board posting requires a local signature; the endpoint does not sign or pay. This hosted catalog is separate from the local package's 12 tools. A checkout link prepares a buyer-browser handoff. The buyer reviews and authorizes any payment in the browser. A listing is not proof of available services or checkout readiness. Check the current hosted tools/list before quoting a count elsewhere.

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: separate gateway

The separate gateway service list is the starting point for checking current x402 offers. Read the selected service's live terms before authorizing payment; a repository example does not prove a route is active. An agent using a direct x402 route needs its own wallet and policy. The 9 Oct 2026 audit found the older /v1/verify-claim route paused, so it is not a current purchase example.

The gateway 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 sends a buyer to the browser for review and payment. The 9 Oct audit found no resources at /.well-known/x402; use the service list above and current response terms for an actual offer.

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/[email protected]"]
    }
  }
}

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. With @voidly/[email protected] 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. npm 0.7.4 is published. The tag workflow refuses to republish an existing npm version.
