RASON

A local MCP server that lets an assistant build, solve and analyze RASON optimization, simulation and decision models through the RASON REST API.

What you can do

Create and manage RASON decision models, including optimization, simulation and data science models, through the RASON API using a bearer token. Solve models and retrieve results, with large arrays and dataFrames summarized and oversized results truncated according to configured limits. Run diagnostics on models and requests to check them before or after solving. Point the server at a different RASON REST API base URL when needed.

When to use it

Useful when you work with RASON models and want an assistant to draft, solve and inspect them without leaving the conversation, especially for optimization or simulation studies that need repeated runs and result checks.

Requirements

Runs as a local process (npm package or MCPB bundle) on a desktop machine. Requires a RASON API bearer token in RASON_BEARER_TOKEN, obtained from the RASON site, and network access to the RASON REST API. Optional settings cover request timeout, result array row limit, result size limit and an alternate API base URL.
