Sierra MCP Bridge

Read selected Sierra Chart study outputs from MCP clients. The bridge runs beside Sierra and offers eight read-only tools over Streamable HTTP or local stdio. It does not call a model API and needs no LLM API key.

Status: 0.1.0 alpha. One Windows/Sierra installation has demonstrated Entra OAuth, ngrok HTTPS, Windows services and authenticated ChatGPT reads across two charts. Independent installation and broader lifecycle validation are ongoing.

Features

  • Optional bounded chart discovery, saved exporter IDs and explicit paths.

  • Chart symbol/timeframe and selected study names, settings, colors and values.

  • Up to 200 loaded bars of history, with forming-bar status and quality warnings.

  • Microsoft Entra OAuth, optional ngrok exposure and optional NSSM services.

Tools: get_startup_context, list_charts, list_studies, get_snapshot, get_study_values, get_study_history, get_footprint, get_data_health.
