[](https://jsr.io/@yamanoku/baseline-mcp-server) ## Overview This server implements an MCP server that can retrieve Baseline status (support status) of Web API features using the [Web Platform Dashboard](https://webstatus.dev/) API. It fetches information about web features based on queries and returns the results to MCP clients.  ## Features - Feature search using Web Platform Dashboard API - Providing Baseline status (`widely`, `newly`, `limited`, `no_data`) for features - Browser implementation status (version and release date) - Feature usage data - Feature search excluding specific browsers (`chrome`, `edge`, `firefox`, `safari`) - Integration with various AI models via MCP ## About Baseline Status Baseline status indicates browser support for web features: - **widely**: Widely supported web standard features. Safe to use in most browsers. - **newly**: Newly standardized web features. Beginning to be supported in major browsers but still in the process of adoption. - **limited**: Web features with limited support. May not be available in some browsers or may require flags. - **no_data**: Web features not currently included in Baseline. Browser support status needs to be checked individually. For more details about Baseline, refer to "[Baseline (Compatibility) - MDN Web Docs Glossary](https://developer.mozilla.org/en-US/docs/Glossary/Baseline/Compatibility)". ## MCP Client Configuration - Deno is recommended for running the server - Please only allow access to `api.webstatus.dev` as a permission - Specify [`@yamanoku/baseline-mcp-server`](https://jsr.io/@yamanoku/baseline-mcp-server) or set up your local environment to read baseline-mcp-server.ts ### Claude Desktop To use with Claude Desktop's MCP client, add the following configuration to `cline_mcp_settings.json`: ```json { "mcpServers": { "baseline-mcp-server": { "command": "deno", "args": [ "run", "--allow-net=api.webstatus.dev", "jsr:@yamanoku/baseline-mcp-server" ] } } } ``` ### Visual Studio Code To use with Visual Studio Code's MCP client, add the following configuration to `settings.json`: ```json { "mcp": { "servers": { "baseline-mcp-server": { "command": "deno", "args": [ "run", "--allow-net=api.webstatus.dev", "jsr:@yamanoku/baseline-mcp-server" ] } } } } ``` ## Running with Docker First, build the Docker image: ```shell docker build -t baseline-mcp-server . ``` Configure your MCP client to run the Docker container: ```json { "mcpServers": { "baseline-mcp-server": { "command": "docker", "args": [ "run", "-i", "baseline-mcp-server:latest" ] } } } ``` ## Acknowledgements The logo for this OSS was created by GPT-4o Image Generation, and the implementation and documentation samples were suggested by Claude 3.7 Sonnet.
