Solispec MCP server

An MCP server for Solispec, the browser app for solar installers: mounting frame design, snow and wind load checks, bill of materials, calculation reports and client proposals.

It lets an AI assistant (Claude, Cursor, VS Code and other MCP clients) work with your Solispec organization through the public Solispec API: list and update projects, read the calculation report of a version, create a commercial proposal, manage clients and your price list.

The API is part of the Solispec Business plan. Create a key in the cabinet: solispec.com/app/api. A read key can only read; a write key acts as a member of the organization.

Tools

Set SOLISPEC_READ_ONLY=1 to expose the read tools only.

Environment

Examples

• "List my projects in status offer and summarize the loads of each."

• "Open version 2 of the Kraków project and tell me which structural check is closest to its limit."

• "Create a proposal from version 3 with three options, valid 14 days, for client Anna Weber."

• "Raise all fastener prices by 5 %, show me the changes first."

Notes

• The calculation itself runs on the Solispec server; this package is a thin API client and contains no engineering code.

• Results are a design aid. Loads and structural checks must be verified by a qualified engineer for the actual site.

• Free calculators (snow and wind loads, string sizing, ballast, battery backup, tilt and row spacing) are on solispec.com and need no key.
