stacksfinder — Claude Code MCP server: what it does, how to install
This MCP server recommends technologies, compares stacks, estimates projects, and checks technical debt. It works with Claude Code and other MCP clients.
claude mcp add stacksfinder -e STACKSFINDER_API_KEY=<STACKSFINDER_API_KEY> -- npx -y @stacksfinder/mcp-serverWhat stacksfinder does
stacksfinder gives an agent tools for making technology choices and inspecting a project. It can group available technologies, compare alternatives, suggest a stack, and build an MCP project kit from a description. Repository analysis can also identify relevant MCP servers and prepare an .env-mcp credentials template.
Other tools cover project scope, pricing, and market analysis, plus technical-debt audits and migration suggestions. Several features work without an account, including a daily stack recommendation and project-kit tools. An API key is required for estimates, expanded recommendations, and audits, so those tools depend on STACKSFINDER_API_KEY.
What it helps with
- choose a stack for a project brief
- compare several technologies side by side
- estimate project scope and pricing
- audit a stack for technical debt
- find MCP servers for a repository
Example prompts for the agent
