empulse-mcp

A small stdio bridge to the EMpulse Street FX Index MCP server (https://api.empulse.ai/mcp) for clients that only speak stdio. Standard library only, no build step: every JSON-RPC message from stdin is posted to the remote server and the answer is written to stdout. Clients that support remote servers can skip this package and connect to the URL directly — see https://github.com/empulse-ai/empulse-mcp#connect.

Install and run

uvx empulse-mcp                       # or: pipx run empulse-mcp
EMPULSE_API_KEY=emp_... uvx empulse-mcp

Client configuration (Claude Desktop, Cursor, Windsurf, Zed, …):

{
  "mcpServers": {
    "empulse": {
      "command": "uvx",
      "args": ["empulse-mcp"],
      "env": { "EMPULSE_API_KEY": "emp_..." }
    }
  }
}

Environment: EMPULSE_API_KEY (optional — without it the free level applies: free currencies, data up to yesterday, a daily limit per network), EMPULSE_MCP_URL (default https://api.empulse.ai/mcp).

What the server offers

Street exchange rates of emerging-market currencies against the US dollar — the rate people actually pay where the official rate is managed, lagging or unavailable — built from transaction-based market data and quotes from independent public market sources, with a confidence class and the number of sources on every figure.

Tools: get_street_rate, get_rate_history, list_currencies, get_official_vs_street, get_stress_signals, get_fx_events, get_hourly, get_rail_health, get_rail_incidents, get_unmet_demand, get_usdt_liquidity, get_methodology, request_free_key. Resources: empulse://methodology, empulse://coverage, empulse://pricing. Every answer carries source, as_of, confidence and a ready citation.
