CostBench is a Model Context Protocol (MCP) server: Verified pricing, hidden costs, negotiation data, price changes & TCO for 3,390+ software products. Because it speaks the Model Context Protocol, AI assistants can use CostBench as a set of callable tools instead of you copy-pasting between apps.
It's a hosted (remote) server — point your client at https://costbench.com/mcp and you're connected, with nothing to install locally. The current release is v1.1.0, published under the MIT license, with source at aadilr/costbench-mcp on GitHub.
On mcp.site, CostBench sits in the AI & Agents category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
