ai.kaiv/can-i-use MCP Server

The ai.kaiv/can-i-use MCP server provides browser support for web features, sourcing live data from caniuse. It reports from which version a feature is supported and whether that support is considered safe to ship. It is focused on delivering version-level compatibility information for web features.

🛠️ Key Features

Live browser support data from caniuse
Indicates the version where a feature becomes available
Assesses whether it is safe to ship

🚀 Use Cases

Checking cross-browser compatibility for specific web features
Determining release readiness based on browser version support
Verifying whether a feature is supported before deployment

⚡ Developer Benefits

Version-specific compatibility answers for planning changes
“Safe to ship” guidance grounded in caniuse data

⚠️ Limitations

Limited to browser support information for web features; no other data sources are described

Captured live from the server via tools/list.

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.

Parameters1

feature

string

required

Feature name or caniuse id. Loose names are resolved, e.g. "has selector" finds "css-has".

Raw schema

{
  "type": "object",
  "properties": {
    "feature": {
      "type": "string",
      "x-in": "query",
      "description": "Feature name or caniuse id. Loose names are resolved, e.g. \"has selector\" finds \"css-has\"."
    }
  },
  "required": [
    "feature"
  ]
}

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.

Parameters1

string

required

Exact caniuse feature id, e.g. "css-has".

Raw schema

{
  "type": "object",
  "properties": {
    "id": {
      "type": "string",
      "x-in": "query",
      "description": "Exact caniuse feature id, e.g. \"css-has\"."
    }
  },
  "required": [
    "id"
  ]
}

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.

Parameters1

string

required

Free-text query, e.g. "grid" or "web share".

Raw schema

{
  "type": "object",
  "properties": {
    "q": {
      "type": "string",
      "x-in": "query",
      "description": "Free-text query, e.g. \"grid\" or \"web share\"."
    }
  },
  "required": [
    "q"
  ]
