Sierra Chart MCP

Status: Experimental, local-use software. It has not been audited for unattended use.

Sierra Chart MCP is a local Model Context Protocol server and launcher for configuration and diagnostics only. It lets an MCP client observe Sierra Chart, inspect chartbooks/charts/studies/drawings/data, read diagnostic information, and apply narrowly validated configuration changes through a local bridge.

Safety boundary: This project has no order execution, trading, position, account, credential, or broker-control features. It is not affiliated with, endorsed by, or sponsored by Sierra Chart. Sierra Chart is a trademark of its respective owner.

 Sierra Chart runtime

The server validates tool inputs, assigns request IDs, filters restricted response fields, and waits for a matching bridge response. The bridge study always uses <Sierra DataFilesFolder>/SierraMCP; it has no queue-root input. Set SIERRA_MCP_ROOT in the server to that exact directory. Use one Controller Instance=Yes bridge in the controller chart. Any chart-targeted setting requires a non-controller bridge on each controlled chart.

Supported tools

The public tool surface includes sierra_status, sierra_chartbooks, sierra_charts, sierra_studies, sierra_drawings, sierra_data, sierra_diagnostics, and sierra_control. Read operations are the default. Mutating operations require explicit targets, expected chartbook/chart identity where applicable, and idempotency keys.

Quick start

1. Install Sierra Chart and the supported build prerequisites for your platform.

2. Build or obtain the ACSIL bridge study and add it manually to a controller chart.

3. Build the server and launcher with the repository instructions in docs/installation.md.

4. Point your MCP client at the generated server entry point using placeholders as shown in docs/mcp-client-config.md.

5. Run the health checks and confirm the bridge heartbeat before using configuration tools.
