Agent Rynku - Warsaw Stock Exchange (GPW) data for your agent MCP server

Agent Rynku MCP: Warsaw Stock Exchange (GPW) data for your AI agent

Agent Rynku is a hosted Model Context Protocol server with 93 tools for the Polish stock market: live and historical quotes, ESPI/EBI filings with an assessment of each one, quarterly KPIs extracted from company documents, earnings forecasts with a track record, and portfolio analytics in PLN.

Connect it to Claude, Cursor, or any MCP client and ask things like:

• "What did KGHM report today, and how does it compare with the forecast?"
• "Show WIG20 companies after their latest results."
• "Which of my positions are above 20% concentration?"
• "How much tax will I owe on this year's sales?"

Quick start

1. Get an API key. Create a free account at agentrynku.pl and generate a key in settings. The free account covers unlimited data tool calls; only the LLM-backed companion queries are metered. The bridge below makes one check call per start to verify the key.

2. Connect your client. The server speaks Streamable HTTP at:

https://agentrynku.pl/api/mcp

with the header Authorization: Bearer YOUR_KEY.

Claude Code

claude mcp add --transport http agentrynku https://agentrynku.pl/api/mcp \
  --header "Authorization: Bearer YOUR_KEY"

Cursor and other clients with remote HTTP support

{
  "mcpServers": {
    "agentrynku": {
      "type": "http",
      "url": "https://agentrynku.pl/api/mcp",
      "headers": { "Authorization": "Bearer YOUR_KEY" }
    }
  }
}

Claude Desktop and other clients that only run local commands

This package is a small stdio bridge to the hosted server (it uses mcp-remote):

{
  "mcpServers": {
    "agentrynku": {
      "command": "npx",
      "args": ["-y", "agentrynku-mcp"],
      "env": { "AGENTRYNKU_API_KEY": "YOUR_KEY" }
    }
  }
}

More configs in examples/.

Try before signing up: initialize and tools/list work without a key, so you can see the full catalogue first:

curl -s https://agentrynku.pl/api/mcp \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'
