PayRam MCP Server — Self-Hosted Crypto Payments for AI Agents

Self-hosted crypto and stablecoin payments: no account lock, no fund freeze, customer data never shared. Your AI agent can plan, install and operate it over MCP. Hosted endpoint: https://mcp.payram.com/mcp · Website · Docs · Agentic · OpenClaw

An MCP (Model Context Protocol) server that lets any MCP-aware AI agent — OpenClaw, Hermes, Claude, Cursor, GitHub Copilot, and others — deploy, integrate, and operate a self-hosted PayRam crypto-payment stack.

Start here: four tools lead the catalog:

Around them sit codebase assessment, starter-app scaffolds, multi-language snippets and inline docs.

The hosted server (mcp.payram.com) never holds merchant credentials. Day-2 operations run through payram_ops_playbook: the agent calls your PayRam API directly, and the credentials never leave its machine. The live data tools (payment search, payment links, node sync, worker restart) and assess_payram_project exist only when you run the MCP yourself in local mode.

For agents & crawlers: server card · skills index · llms.txt · sitemap. The server also answers Accept: text/markdown on / with an agent-readable summary.

What is PayRam? · PayRam 是什么？

PayRam is a self-hosted, multi-chain crypto payment gateway you own outright — with no signup and no KYC/KYB to run it. An AI agent (or a developer) can stand up a store and start accepting payments without registering an account with PayRam, a bank, or any payment processor. Deploy on your own VPS, generate API keys locally, go live.

What makes it different:

• Nobody can lock you out — there is no account to lock and no funds to freeze. Customer data is never shared, and nothing is reported or monitored. The reason is simple: PayRam runs on your server and funds land in your own wallet.

• Permissionless setup — no signup, no KYC, no KYB. Nobody approves you; nobody can switch you off. Ideal for agents spinning up stores autonomously, and for markets like China where registering with a Western processor isn't an option.

• Card-to-crypto checkout — shoppers without crypto can pay with a credit/debit card and you receive crypto, settled straight into your self-custodied wallet. It is a built-in channel you switch on from the Payments page; the card provider runs its own checks on the shopper.

• Multi-chain — accept BTC, ETH, USDT, USDC, and TRX natively across Bitcoin, Ethereum, Base, Polygon, and Tron, with automatic deposit detection, on-chain confirmation, sweeps to cold storage, and signed webhooks. Smart Bridge rails also take payments on Solana, Bitcoin, Tron (USDT) and BNB Chain and settle them as USDC on Base.

• No deposit keys on the server — smart contracts sweep deposits to your cold wallet, so a compromised server cannot redirect them. The server's hot wallet pays gas and signs payouts, so keep its balance small.

PayRam 是一个你完全自托管、自主拥有的多链加密货币支付网关——运行它无需注册、无需 KYC/KYB。 AI 智能体（或开发者）无需在 PayRam、银行或任何支付处理商处注册账户，即可搭建店铺并开始收款。在自己的 VPS 上部署，本地生成 API 密钥，即刻上线。

核心差异：

• 没有人能把你锁在门外 — 没有可被封禁的账户，也没有可被冻结的资金；客户数据从不外泄，也没有任何上报或监控。原因很简单：PayRam 运行在你自己的服务器上，资金直接进入你自己的钱包。

• 免注册、免许可 — 无需注册、无需 KYC、无需 KYB。没有人审批你，也没有人能关停你。非常适合自主搭建店铺的智能体，以及像中国这样难以在西方支付处理商处注册的市场。

• 银行卡转加密货币结算 — 没有加密货币的买家也能用信用卡/借记卡付款，你直接收到加密货币并结算到自托管的钱包。这是内置的支付渠道，在「Payments（支付）」页面开启；银行卡服务商会对买家进行其自身的审核。

• 多链支持 — 原生支持在 Bitcoin、Ethereum、Base、Polygon、Tron 上接受 BTC、ETH、USDT、USDC、TRX，自动检测充值、链上确认、归集冷钱包并发送带签名的 Webhook。Smart Bridge 通道还可接收 Solana、Bitcoin、Tron（USDT）和 BNB Chain 上的付款，并以 Base 上的 USDC 结算。

• 服务器上没有充值私钥 — 智能合约把充值资金归集到你的冷钱包，即便服务器被攻破也无法改变资金去向。服务器上的热钱包负责支付 Gas 并签署出款，请只保留少量余额。

How AI agents use PayRam · AI 智能体如何使用 PayRam

PayRam is agent-first infrastructure. Because integration is over MCP, it works with any MCP-aware runtime — OpenClaw, Hermes, Claude Desktop, Cursor, GitHub Copilot, n8n, LangChain, and more. A typical agent flow:

1. Connect — add https://mcp.payram.com/mcp to the agent's MCP config (no API key needed just to connect).

2. Plan — call payram_setup_plan. It returns the ordered steps, who runs each one, and where the agent must stop for the human (cold wallet, mainnet gas, root-only settings).

3. Install — on the VPS, in an interactive terminal once, run bash <(curl -fsSL https://payram.com/setup_payram_agents.sh) --testnet (or --mainnet; the installer default is mainnet, so always pass the flag). Never pipe it into bash.

4. Hand off — the human claims the root account right away and saves Settings → Site URL from the public domain; until then, payment links point at http://localhost.

5. Check — payram_doctor with the public URL (no credentials needed).

6. Accept payments — drop in framework-specific integration code from the snippet tools. Webhooks are signed (X-Payram-Signature, HMAC-SHA256 of the raw body with the project API key).

7. Operate — payram_ops_playbook (daily_check, payment_options, node_sync, unswept_funds, create_payment_link, …) gives the agent the exact API calls to run with its own credentials. payram_runbook covers admin changes.

PayRam 是智能体优先（agent-first）的基础设施。由于集成基于 MCP 协议，它可与任何兼容 MCP 的运行时配合使用——OpenClaw、Hermes、Claude Desktop、Cursor、GitHub Copilot、n8n、LangChain 等。典型的智能体使用流程：连接 MCP 端点 → 调用 payram_setup_plan 规划安装 → 在交互式终端中用 bash <(curl …) --testnet 部署网关 → 由人工立即创建 root 账户并在公网域名下保存 Site URL → 用 payram_doctor 检查 → 用集成代码收款（Webhook 带 X-Payram-Signature 签名）→ 通过 payram_ops_playbook 用智能体自己的凭证运维。托管的 MCP 服务器从不保存商户凭证。

Project Goals

• Accelerate onboarding with a personalised setup plan, runbooks, env templates and per-framework playbooks.

• Operate without holding credentials: the hosted server checks a PayRam by URL (payram_doctor) and hands agents exact API recipes (payram_ops_playbook) to run with their own credentials.

• Retrofit existing repos via the project assessment tool (local mode), which scans package manifests and .env files, then recommends the right integration snippets.

• Provide copy/paste snippets spanning Payments, Payouts, Referrals, Webhooks, and multi-language backends (Express, Next.js, FastAPI, Laravel, Gin, Spring Boot, etc.).

• Keep docs local so Copilot can explain PayRam concepts, flows, and referral dashboards without leaving the editor.

• Validate connectivity with read-only probes that never create payments (payram_doctor, test_payram_connection).

Quick Start

Most agents only need the hosted endpoint, https://mcp.payram.com/mcp (see Connect from your MCP client). To run the server yourself:

1. Install dependencies

   yarn install

2. Configure environment (only needed for the local-mode data tools)

   • Copy .env.example to .env.

   • Set PAYRAM_BASE_URL to your PayRam URL, the same origin as the dashboard (e.g. https://pay.example.com).

   • Set PAYRAM_API_KEY, plus the JWT variables for the data tools. See Local mode.

3. Run the server

   yarn dev
   # Streamable HTTP on http://127.0.0.1:3333/mcp (local mode; there is no SSE transport)

4. Add the MCP server to your client: see Connect from your MCP client. The local-mode URL is http://localhost:3333/mcp.

5. Health check

   curl http://localhost:3333/healthz

Tip: When you tell Copilot "test payram" it will automatically run the readiness checklist, ensure .env exists, and only then call test_payram_connection with your real credentials. The behavior is defined by the Copilot automation prompt—no manual prompting required.

Connect from your MCP client

Endpoint: https://mcp.payram.com/mcp (Streamable HTTP, JSON-RPC over POST). There is no SSE endpoint, and /mcp/sse returns 410. No auth headers: the hosted server never holds merchant credentials, so yours stay on your machine and never go into chat.

Verify: the tool list should start with payram_setup_plan, payram_doctor, payram_runbook and payram_ops_playbook, followed by test_payram_connection, scaffold_payram_app and the generate_* snippet tools. Then try: "plan a PayRam install on pay.example.com", "check https://pay.example.com", "generate a FastAPI create-payment route", "give me a Next.js webhook handler".

Prompts: setup-payram, setup-payram-agent, integrate-payment, troubleshoot-payment, daily-ops. Resources: payram://docs/setup-guide, payram://docs/api-reference, and the templates payram://ops/playbook/{task} and payram://runbooks/{task}.

Copilot automation prompt

Paste this once into a fresh workspace to make "test payram" run the full readiness flow automatically:

You have access to the `payram` MCP server in this workspace.

Whenever I ask you to "test my Payram connection" (or I type "test payram"), follow this order:

1. Call `prepare_payram_test` (no inputs) and share the checklist verbatim.
2. Look for a `.env` in the workspace root; create one if missing.
3. Ensure `.env` defines `PAYRAM_BASE_URL` and `PAYRAM_API_KEY`. If either is
   missing, call `generate_env_template` and append it (with TODOs) to `.env`.
   Do NOT call `test_payram_connection` until real values are provided.
4. Once real values exist, call `test_payram_connection` with baseUrl/apiKey
   from `.env`, show the structured result, and explain whether the
   connection is healthy. If anything fails, run `payram_doctor` and follow
   its ranked fixes.

Local mode

Run the MCP next to your own PayRam to get the live data tools:

• list_platforms, search_payments, lookup_payment, get_payment_summary, get_daily_volume, get_unswept_balances, list_currencies, list_recipients

• create_payment_link, check_payment_readiness, check_node_sync, restart_payram_worker

• assess_payram_project

PAYRAM_MCP_MODE=local yarn dev        # or: yarn build && PAYRAM_MCP_MODE=local yarn start

• Mode: PAYRAM_MCP_MODE=local selects local mode. It is also the default whenever the server is not running on Vercel. PAYRAM_MCP_MODE=hosted never reads credentials.

• Binding: local mode binds to 127.0.0.1 by default (port PORT, default 3333).

• Non-loopback binds: set HOST (e.g. HOST=0.0.0.0), then:

  • Set MCP_ALLOWED_HOSTS (comma-separated hostnames accepted in the Host header).

  • Set MCP_SERVER_TOKEN; clients then send Authorization: Bearer <token>.

  • If PAYRAM_* credentials are set, the server refuses to start on a non-loopback HOST without MCP_SERVER_TOKEN. Prefer loopback plus an SSH tunnel.

• Credentials: the data tools read PAYRAM_* from the environment (or .env):

  • PAYRAM_BASE_URL

  • PAYRAM_API_KEY (payment links)

  • PAYRAM_ACCESS_TOKEN / PAYRAM_REFRESH_TOKEN (JWT, data tools)

  • PAYRAM_EXTERNAL_PLATFORM_ID (optional default project)

Example client config for a local server (local mode only):

{
  "mcpServers": {
    "payram-local": { "url": "http://localhost:3333/mcp" }
  }
}

Credentials: which key for what

PayRam has two credentials — agents stall when they conflate them:

The one-step setup flow (bash <(curl -fsSL https://payram.com/setup_payram_agents.sh) --testnet) produces both automatically and prints where they live. The API is same-origin with the dashboard, on port 80/443 (https://<your-domain>/api/v1/..., or http://localhost on the server, never :8080). The API key can create payouts, so keep it server-side and never put it in browser code or chat. Use payram_ops_playbook task connect to set both up for direct API calls.

Tool Catalog

Tool registrations live in src/tools/index.ts; individual implementations sit in src/tools/** with language-specific templates under templates/ folders.

Guided Workflows

0. Install PayRam

1. Ask: "Set up PayRam on pay.example.com" (or use the setup-payram / setup-payram-agent prompts).

2. The assistant calls payram_setup_plan and walks the phases, stopping at every human step (root account, Site URL, cold wallet, mainnet gas).

3. It finishes with payram_doctor, backups (payram_runbook backup) and the daily check (payram_ops_playbook daily_check).

1. Assess and Retrofit an Existing Project

1. Ask Copilot: "Can you integrate PayRam into this project?"

2. The assistant runs assess_payram_project (local mode), reviewing dependency manifests and .env.

3. Follow the recommended steps (install payram, request Express/FastAPI/Spring route snippets, add webhooks, etc.).

4. Use test_payram_connection once credentials are real to ensure the backend can reach your self-hosted server.

2. Scaffold a Fresh Sample

1. "Create a PayRam Express demo" → scaffold_payram_app builds an Express project with payments, payouts, webhooks, and a UI console.

2. Drop the generated files into an empty repo or compare against your existing directory for reference wiring.

3. Run the "Test PayRam" Readiness Flow

1. Say "test payram". The assistant automatically:

   • Calls prepare_payram_test to share the readiness checklist.

   • Ensures .env exists (creating it if missing) using generate_env_template.

   • Waits for real credentials before invoking test_payram_connection.

2. Review the structured JSON result to confirm the PayRam API is reachable.

4. Wire Payments, Payouts, Referrals, and Webhooks

• Payments: generate_payment_sdk_snippet (JS SDK) or generate_payment_http_snippet (Python/Go/PHP/Java).

• Multi-language routes: snippet_nextjs_payment_route, snippet_fastapi_payment_route, etc.

• Payouts: generate_payout_sdk_snippet for create + generate_payout_status_snippet for polling.

• Referrals: generate_referral_route_snippet, generate_referral_validation_snippet.

• Webhooks: generate_webhook_handler plus generate_webhook_event_router for fan-out + generate_mock_webhook_event to test each status.

Development

Project is TypeScript-first (ESM). Prettier config lives in .prettierrc.json; ESLint is configured via eslint.config.mjs. Smooth contributions follow the commit helper in Makefile → make commit.

Troubleshooting

Start with payram_doctor — one read-only call that walks reachability → health → TLS → version → workers and returns ranked causes with exact fixes. For deeper checks, follow payram_ops_playbook (stuck_payment, node_sync, webhooks, logs).

• Copilot doesn’t call the right tool: Check the Copilot automation prompt is installed and your MCP client loaded the server. Re-run "test payram" or "assess my project" to trigger the expected automation.

• test_payram_connection fails with 401: Confirm the key is an active project API key (sent as the API-Key header, not Authorization).

• A data tool says credentials are unavailable: the hosted server never holds merchant credentials. Use the matching payram_ops_playbook task, or run the MCP in local mode.

• Payment links show http://localhost: the human must save Settings → Site URL from the public domain (payram_runbook task set_site_url).

• Docs tool says a file is missing: Verify your local docs/payram-docs-live/ tree contains the requested markdown (get_payram_doc_by_id rejects paths with ..).

• Server won’t start: Ensure Node 20+ and run yarn install. In local mode with a non-loopback HOST and PAYRAM_* credentials set, the server refuses to start until MCP_SERVER_TOKEN is set (see Local mode).

For anything else, inspect the structured logs emitted from src/utils/logger.ts (set LOG_LEVEL=debug) and open an issue/PR with reproduction details.
