Any compliant MCP client can build, read, validate, and\nsave `.stmx` files in the XMILE format; optional host features still vary.\n\n## What is this for?\n\n**Stella** is a system dynamics modeling tool used for simulating complex systems in fields like ecology, biogeochemistry, economics, and engineering. This MCP server allows AI assistants to:\n\n- **Create models from scratch** - Build stock-and-flow diagrams programmatically\n- **Read existing models** - Parse and understand .stmx files\n- **Validate models** - Check for errors like undefined variables or missing connections\n- **Modify models** - Add stocks, flows, auxiliaries, and connectors\n- **Save models** - Export valid XMILE files that open in Stella Professional\n\nThis is particularly useful for:\n- Teaching system dynamics modeling\n- Rapid prototyping of models through natural language\n- Batch creation or modification of models\n- Documenting and explaining existing models\n\n## Installation\n\n### From PyPI\n\n```bash\npip install stella-mcp\n```\n\n### From source\n\n```bash\ngit clone https://github.com/bradleylab/stella-mcp.git\ncd stella-mcp\npip install -e .\n```\n\n### Requirements\n\n- Python 3.10+\n- `mcp>=2.0.0,<3`\n\n## Configuration\n\n### Via uvx (no install required)\n\nIf you have [uv](https://docs.astral.sh/uv/) installed, the lowest-friction\nconfiguration runs the published package directly:\n\n```json\n{\n  \"mcpServers\": {\n    \"stella\": {\n      \"command\": \"uvx\",\n      \"args\": [\"stella-mcp\"]\n    }\n  }\n}\n```\n\n### Claude Desktop\n\nAdd to your `claude_desktop_config.json`:\n\n```json\n{\n  \"mcpServers\": {\n    \"stella\": {\n      \"command\": \"stella-mcp\"\n    }\n  }\n}\n```\n\n### Claude Code\n\nAdd to your `.claude/settings.json`:\n\n```json\n{\n  \"mcpServers\": {\n    \"stella\": {\n      \"command\": \"stella-mcp\"\n  …","publisher":null,"homepage":null,"repository":null,"version":"0.14.0","license":null,"protocols":["mcp"],"tags":["mcp"],"pricing":null,"endpoints":[{"url":"pypi:stella-mcp","type":"package_pypi","auth":null,"probeable":false}],"skills":null,"tools":null,"extra":null,"attribution":{"kind":"pypi","name":"pypi","summary":"pypi","version":"pypi","description":"pypi"}},"derived":{"capabilities":[{"slug":"commerce.ecommerce","name":"E-commerce Operations","confidence":0.791,"provenance":"derived"},{"slug":"dev.package-management","name":"Packages & Dependencies","confidence":0.768,"provenance":"derived"},{"slug":"dev.version-control","name":"Version Control","confidence":0.745,"provenance":"derived"}],"categories":["commerce","dev"],"language":"en"},"observed":{"status":"unknown","statusReason":"Distributed as a package to run locally; no network endpoint to check.","lastOkAt":null,"lastProbedAt":null,"statusComputedAt":null,"reliability30d":null,"latestObservations":[],"tools":null,"package":{"name":"stella-mcp","registry":"pypi","observedAt":"2026-11-04T01:24:55.579Z","publishedAt":"2026-08-10T02:04:37.306896Z","latestVersion":"0.14.0"},"toolSurface":null,"endpointFacts":[]},"verification":{"claimed":false,"claimedAt":null,"proofs":[]},"provenance":{"sources":[{"source":"pypi","key":"stella-mcp","url":"https://pypi.org/project/stella-mcp/","firstSeenAt":"2026-09-10T13:19:42.736Z","fetchedAt":"2026-11-04T01:23:49.299Z","normalizedAt":"2026-11-04T01:23:49.299Z"}]},"firstSeenAt":"2026-09-10T13:19:42.736Z","updatedAt":"2026-11-04T01:24:55.579Z"}
