MCP Server Config Compatibility

Entry
JSON All of v2.1.136
EntryKind: in v2.1.136,
ChangesSection of the release

Claude Code now accepts streamable-http as an MCP transport alias for HTTP and gives clearer errors for invalid MCP server types.

Usage
{
  "mcpServers": {
    "example": {
      "type": "streamable-http",
      "url": "https://example.com/mcp"
    }
  }
}
Evidence

MCP transport normalization and validation (search for "streamable-http" and "Valid types are: stdio, sse, http (or streamable-http), ws, sdk")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
