About
Local MCP access to Stochastly desktop nodes, diagnostics and research tools.
Security Report
This is a launcher/wrapper MCP server for the Stochastly desktop application with reasonable security posture. The code properly delegates to a local desktop app when available and provides a safe fallback that refuses all tool calls with informative error messages. Minor concerns exist around path traversal via environment variable override and lack of input validation on the fallback handler, but these are appropriately scoped to local operation and do not represent significant security risks. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.

Stochastly MCP
This small public launcher connects an MCP client to the server shipped with the Stochastly desktop app. The app must be installed, running, and licensed for Atelier or Portfolio. The package contains no Stochastly engine code.
Install with pip install stochastly-mcp or run with uvx stochastly-mcp. To try the unpublished source, install this directory with pip install ..
Configure a local stdio server with command stochastly-mcp and no arguments:
- Claude Desktop: add
"stochastly": {"command": "stochastly-mcp"}undermcpServersinclaude_desktop_config.json. - Cursor: add the same entry under
mcpServersin.cursor/mcp.json. - VS Code: add
"stochastly": {"type": "stdio", "command": "stochastly-mcp"}underserversin.vscode/mcp.json.
The server exposes 29 tools, among them node_catalog, compose_graph, backtest_graph, red_flag_check, adversarial_check, portfolio_combine and export_paper. The installed app runs them and checks the licence on every call: portfolio_combine needs Portfolio, every other tool Atelier or Portfolio.
Without the app, the launcher lists the same 29 tools (names, descriptions, input schemas and annotations from stochastly_mcp_data/tools_manifest.json, generated from the app's server), so a client can see what the server offers. Each description then starts with a note that the desktop app is required, and every call returns a structured answer with ok: false, the edition needed and a link to pricing. The manifest is metadata only.
For a nonstandard installation, set STOCHASTLY_MCP_SCRIPT to the installed app's stochastly_mcp.py. This is a local path, not a network endpoint.
