Stock Price API
io.github.Br0ski777Published by GitHub account Br0ski777v1.1.0Updated Oct 25, 2026
Real-time stock quotes — price, change, volume, market cap. x402 micropayment.
The publisher's own server: PriceWin
Overview
A remote MCP server that returns real-time stock quotes — price, change, volume and market cap — for a ticker symbol, paid per call via x402.
- What you can do
- Fetch a real-time stock quote for a ticker symbol, returning price, change, change percent, volume, market cap, company name, exchange, previous close and day high/low as JSON.
- When to use it
- Useful when an assistant needs current stock prices for portfolio monitoring, financial analysis, stock dashboards, price alerts or investment research. It is not for crypto prices, currency conversion or weather.
- Requirements
- A remote MCP endpoint added to the client configuration; no API key or signup. Each call is paid per use in USDC on the Base L2 network through the x402 protocol, so an x402-capable client and a funded wallet are needed to complete the payment challenge.
Installation
In SourceWeft
- Open Stock Price API in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Web executable via SSE. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.github.Br0ski777%2Fstock-price/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Other MCP clients
Add this to your client's mcpServers config.
