Exchange Rate Mcp

Name: Exchange Rate Mcp
Author: LLM Mart

No install snippet on purpose. A working MCP config is a command, its arguments and an environment block — the last two are where API keys live, so this catalogue never stores them and cannot publish them. Follow the link above for the authors' own instructions.

Live currency exchange rates and amount conversion for 30+ currencies, accepting both ISO codes (USD) and Chinese names (美元), based on ECB daily reference rates.

Try it in 30 seconds: a free public MCP endpoint is already running — just paste the URL into your MCP client (no install, no API key).
Or self-host: a single Python file, stdlib HTTP + FastMCP, zero paid dependencies.

⚡ Use the hosted endpoint (no setup)

https://mcp.pianam.cn/exchange-mcp/mcp

Transport: Streamable HTTP (MCP 2025-03-26 compatible). No authentication required.

🔌 Client configuration

Add this to your MCP client's mcpServers configuration (Claude Desktop claude_desktop_config.json, Cursor mcp.json, Cline, Cherry Studio, etc.):

{
  "mcpServers": {
    "exchange-rate": {
      "type": "http",
      "url": "https://mcp.pianam.cn/exchange-mcp/mcp"
    }
  }
}

Clients that do not accept "type": "http" (some Cherry Studio / older Cline versions) accept the same entry with just "url".

🧰 Tools

Tool	Parameters	Returns
`query_exchange_rate(base="USD", target="", amount=0)`	`base` / `target`: ISO code or Chinese name — `"USD"` / `"美元"` / `"美金"` all work. Empty `target` returns common rates (CNY/EUR/JPY/GBP/HKD/KRW). `amount`: optional, converts N units of base currency.	Rate date, base→target rate, reverse rate, and (when `amount` is given) the converted amount. Reference rates — not live trading prices.

📡 Data sources, caching & limits

Primary source: Frankfurter — European Central Bank (ECB) daily reference rates, free, no API key.
Automatic fallback: open.er-api.com if the primary source fails.
32 currencies with Chinese display names (人民币, 美元, 欧元, 日元, 港币, 韩元, 新台币 …) and Chinese aliases (美金/美刀, 港元, 台币, 澳币 …).
Rates cached for 2 hours (ECB updates on working days); hosted endpoint rate-limited to 200 requests / minute / IP.

🐢 Self-hosting

git clone https://github.com/boy-373/exchange-rate-mcp.git
cd exchange-rate-mcp
pip install -r requirements.txt
python exchange_mcp_server.py
# the server listens on 127.0.0.1:8005 by default; override with:
#   MCP_HOST=0.0.0.0 MCP_PORT=9000 python exchange_mcp_server.py
#   MCP_ALLOWED_HOSTS="your-domain.com,127.0.0.1:*"
#   MCP_ALLOWED_ORIGINS="https://your-domain.com"

Then point your MCP client at http://127.0.0.1:8005/mcp. No API keys or accounts are ever required.

🐳 Self-host with Docker

Option A — pull the pre-built image (fastest, no build):

docker run -d -p 8000:8000 --name exchange-rate-mcp ghcr.io/boy-373/exchange-rate-mcp:latest

Option B — build from source:

git clone https://github.com/boy-373/exchange-rate-mcp.git
cd exchange-rate-mcp
docker build -t exchange-rate-mcp .
docker run -d -p 8000:8000 --name exchange-rate-mcp exchange-rate-mcp

Then point your MCP client at http://127.0.0.1:8000/mcp. The container listens on 0.0.0.0:8000 by default (override with -e MCP_PORT=9000 and adjust -p accordingly). No API keys or accounts required.
