# Voidpay Marketplace MCP [![npm version](https://img.shields.io/npm/v/%40voidly%2Fpay-mcp?label=npm)](https://www.npmjs.com/package/@voidly/pay-mcp) [![MCP Registry](https://img.shields.io/badge/MCP-Registry-blue)](https://registry.modelcontextprotocol.io/?search=io.github.voidly-ai%2Fpay-mcp) [![Glama directory](https://img.shields.io/badge/Glama-directory-6b21a8)](https://glama.ai/mcp/servers/voidly-ai/pay-mcp) [![smithery badge](https://smithery.ai/badge/voidly/voidpay)](https://smithery.ai/servers/voidly/voidpay) 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. ```text 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. ```text 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](https://x402.voidly.ai/v1/services) 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. ```json { "mcpServers": { "voidpay": { "command": "npx", "args": ["-y", "@voidly/pay-mcp@0.7.4"] } } } ``` The [package guide](voidly-pay-mcp/README.md) 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](docs/README.md) adds a quickstart, concepts, examples for all 12 tools, the programmatic API, errors, and FAQ. ### Local plugins The repository includes a [Claude Code plugin](.claude-plugin/plugin.json) with a [repository marketplace](.claude-plugin/marketplace.json), and a [Cursor plugin](.cursor-plugin/plugin.json). 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/pay-mcp@0.7.4` published, add the Claude marketplace from this GitHub repository so its relative plugin source resolves: ```sh 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): ```sh 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.
