WarpPay402 Backend

WarpPay402 operates a hosted MCP server at https://api.warppay402.com/mcp. It answers Streamable-HTTP JSON-RPC POSTs directly (200 application/json) and also the legacy HTTP+SSE transport (GET /mcp opens an event stream whose first event names a per-session /messages?sessionId=... endpoint; ?v=1 and ?v=2 serve the same 19 tools). initialize reports protocolVersion 2024-11-05, serverInfo "WarpPay402 Backend" 1.0.0 and capabilities tools/resources/prompts; resources/list and prompts/list are empty. tools/list is anonymous and returns 19 tools with inputSchema. Tool invocation is metered per call in USDC through the x402 protocol rather than an API key: the REST endpoint behind each tool answers HTTP 402 with a PAYMENT-REQUIRED challenge until a PAYMENT-SIGNATURE is presented, and the provider ships @warppay402/mcp-client, a stdio-to-SSE bridge that signs those challenges with a CUSTOMER_PRIVATE_KEY so Cursor, Windsurf and Claude Desktop can use the tools. An unauthenticated tools/call from this crawler returned 200 with an empty result object rather than a 402, so the payment negotiation for the MCP path is observed only through the bridge.

Connect

This is a remote MCP server — point an MCP client at the endpoint URL. Clients with native remote support (Claude, Cursor, VS Code, …):

# mcp client config (e.g. .mcp.json / mcp settings) { "mcpServers": { "warppay402-com": { "url": "https://api.warppay402.com/mcp" } } }

For stdio-only clients (older Claude Desktop, etc.), bridge with mcp-remote:

# Add to claude_desktop_config.json { "mcpServers": { "warppay402-com": { "command": "npx", "args": ["-y", "mcp-remote", "https://api.warppay402.com/mcp"] } } }

If the server requires authentication, add the provider's token/header (e.g. an X-API-Key) per its docs. A quick reachability check:

curl -i -X POST https://api.warppay402.com/mcp \ -H "Content-Type: application/json" -H "Accept: application/json, text/event-stream" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

About MCP

The Model Context Protocol (MCP) is an open protocol Anthropic introduced for connecting LLM-based agents to external tools and data sources. Providers publish MCP servers that expose their API surface as structured, discoverable tools — an MCP-compatible client (Claude Desktop, Cursor, Cline, Continue, etc.) can connect to the server and call its tools without any per-provider integration code.

Browse every MCP server on the APIs.io network or compare with the broader Agent Skill surfaces of the same providers.

Work with this as data

Every MCP server here is available over the APIs.io API and to AI agents over MCP.
