Overview

AI-generated overview

Lets an assistant look up browser support versions and global usage for web features to judge whether they are safe to ship.

What you can do
This server answers browser-support questions for web features using caniuse data. check_feature_support takes a loose name such as :has(), container queries or css-grid, resolves it to a caniuse feature, and returns the earliest continuously supported version per major browser, global usage percentage, and a conservative safe_to_use flag. get_feature_by_id returns the full support table for an exact feature id with no fuzzy matching, and search_features finds candidate feature ids when a query is ambiguous.
When to use it
Use it when you need to confirm whether a CSS or web feature works in your target browsers, from which version, or to compare several candidate features before adopting new syntax or an API.
Requirements
Network access to the remote endpoint at over streamable HTTP. No authentication, environment variables or headers are declared.
Before you install
No authentication or keys are declared, but queries are sent to a third-party endpoint. The safe_to_use flag is a conservative judgment; still confirm your own target browser range.

Installation

In SourceWeft

  1. Open Can I Use in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/ai.kaiv%2Fcan-i-use/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

check_feature_support

Check Feature Support

Can I use this feature, and from which browser version? Accepts a loose name (":has()", "container queries", "css-grid") and resolves it to a caniuse feature, then returns the earliest continuously-supported version per major browser, global usage percentage, and a conservative safe_to_use flag. Use this first; it answers the whole question in one call.

Parametersfeaturerequired

get_feature_by_id

Get Feature By Id

Support table for an exact caniuse feature id. Use when the id is already known, for example from a previous search. No fuzzy matching is applied.

Parametersidrequired

search_features

Search Features

Find the caniuse feature id for a loose query. Use when a query is ambiguous and you want to choose between candidates before checking support.

Score

83% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

    A hosted service is used under its provider's terms, so no license is expected here. This check is left out of the percentage.
