pyomo-mcp is an MCP server for working with the Pyomo optimization library. It ships with the vendored Pyomo docs from ./pyomo-data/OnlineDocs, exposes a persistent Pyomo execution session, and adds inspection and solver-oriented tooling for LLM workflows.

• Search and read vendored Pyomo docs and example files.
• Execute Pyomo code with pyomo.environ preloaded in a persistent session.
• Inspect models, blocks, variables, objectives, constraints, params, sets, and expressions.
• Evaluate expressions and identify referenced Pyomo variables.
• Detect common solver interfaces and attempt solves when the runtime has solver support.
• Export models to solver formats such as LP.
• Expose MCP tools, resources, prompts, plus HTTP health/readiness routes.

uv sync
uv run python mcp_server.py --transport stdio
uv run python mcp_server.py --transport http --host 127.0.0.1 --port 8000

Health endpoints:

• GET /healthz
• GET /readyz

Important environment variables:

• PYOMO_MCP_DOCS_ROOT
• PYOMO_MCP_EXAMPLES_ROOT
• PYOMO_MCP_TRANSPORT
• PYOMO_MCP_HOST
• PYOMO_MCP_PORT

By default the server reads docs and examples from ./pyomo-data/OnlineDocs. Override that with PYOMO_MCP_DOCS_ROOT and PYOMO_MCP_EXAMPLES_ROOT if you keep pyomo-data elsewhere.
