Baseline MCP Server
AI & MCPTells your agent the Baseline status and browser support of web features, using Web Platform Dashboard data.
Baseline MCP Server is an MCP server that gets the Baseline status of web features from the Web Platform Dashboard API at webstatus.dev.
For a query it returns each matching feature's Baseline status (widely, newly, limited or no_data), browser versions and implementation dates, and usage data. You can also search for features while leaving out a browser such as Safari or Firefox.
Deno is the suggested way to run it, with network access limited to api.webstatus.dev, through jsr:@yamanoku/baseline-mcp-server. Docker and standalone binaries are also available. The main README is in Japanese, and there is an English version.
Good for
- Asking if a CSS feature is Baseline yet
- Finding features Safari has not shipped
- Checking support before adopting new selectors
