ta-lib-mcp

Read-only Python MCP server for TA-Lib indicator discovery and computation.

What It Exposes

• talib_list_indicators: list available indicators with group, category, and search filters.
• talib_get_indicator_info: inspect one indicator's inputs, outputs, parameters, and category.
• talib_compute_indicator: compute an indicator from numeric OHLCV-like arrays.
• talib_list_categories: list indicator categories (Trend, Momentum, Volume, etc.) with descriptions.
• talib_get_version_info: report MCP, Python, and TA-Lib versions.

Requirements

• Python 3.13+
• mcp[cli]
• Optional: TA-Lib (pip install "ta-lib-mcp-server[talib]")

If TA-Lib is missing, the server still starts and returns actionable errors for TA-Lib tools.

Install

pip install -e ".[dev,talib]"

Engineering Rules

• Read-only server behavior only; no stateful or exchange-connected operations.
• External MCP tool inputs are validated in src/ta_lib_mcp/validators.py.
• Do not use eval or exec.
