Coinglass

coinglass-mcp is an MCP server for CoinGlass derivatives data. It exposes funding rates, open interest, long/short ratios, liquidation metrics, and the BTC Bubble Index for LLM workflows that need market structure context.

What It Covers

• Current funding rates across major exchanges
• Funding rate history for one exchange and symbol
• Open interest snapshots and aggregated OI history
• Global long/short account ratio history
• Liquidation summaries and liquidation chart history
• Bitcoin Bubble Index

Why This Server Exists

CoinGlass is useful for derivatives structure, but its API is not ergonomic for agent tool use. This project wraps the API in MCP tools with:

• cleaner tool descriptions
• interval validation
• normalized symbols
• HTTP and stdio transport support
• safer defaults for local deployment

Requirements

• Python 3.11+
• A CoinGlass API key

Quick Start

1. Create your local env file:

cp secrets/coinglass.env.example secrets/coinglass.env

2. Fill in COINGLASS_API_KEY in secrets/coinglass.env.

3. Run locally:

pip install -e .
python -m coinglass_mcp

Docker

docker build -t coinglass-mcp .
docker run --rm -p 38090:38090 --env-file secrets/coinglass.env coinglass-mcp

Tools

Tool	Purpose
get_funding_rates	Current perpetual funding rates across exchanges
get_funding_rate_history	Historical funding rates for a symbol on one exchange
get_open_interest	Current open interest by exchange
get_open_interest_history	Aggregated open interest history

Interpreting the Data

Signal	Typical Interpretation
Funding rate > 0.1%	Longs crowded, higher squeeze risk
Funding rate < -0.05%	Shorts crowded, rebound or squeeze setup
OI rising + price rising	Trend confirmation
OI rising + price falling	Short pressure building
OI falling	Position unwinding
Long/short ratio > 1.5	Retail long crowding
Large long liquidations	Forced selling, can mark local panic
Large short liquidations	Short squeeze / forced upside

Configuration

Variable	Default	Description
COINGLASS_API_KEY	required	CoinGlass API key
COINGLASS_BASE_URL	https://open-api.coinglass.com	API base URL
MCP_TRANSPORT	http	http, streamable-http, sse, or stdio
MCP_HOST	0.0.0.0	Bind host
PORT	38090	HTTP listen port
MCP_PATH	/mcp	MCP endpoint path
MCP_ALLOWED_HOSTS	empty	Extra allowed hosts, comma-separated
MCP_ALLOWED_ORIGINS	empty	Extra allowed origins, comma-separated

Development

Install test dependencies and run tests:

pip install -e ".[test]"
pytest

Security Notes

• Do not commit secrets/coinglass.env
• Prefer using a restricted API key when possible
• Expose the HTTP transport behind your own auth layer if you open it beyond localhost
