This matrix reflects the current SecureMCP-Lite MVP on March 21, 2026.
| Client / platform | Local stdio MCP support in client | SecureMCP-Lite fit today | Notes |
|---|---|---|---|
| Claude Code | Yes | Strong | Best current fit |
| Codex CLI / IDE extension | Yes | Strong | Best current fit |
| Cursor | Yes | Strong | Best current fit |
| Antigravity | Likely yes | Reasonable with caveat | Public MCP config flow appears compatible |
| GitHub Copilot Chat | Yes | Strong | Local editor-side MCP config supported |
| GitHub Copilot CLI | Yes | Strong | Local MCP server config supported |
| Your own local AI agent | Yes | Strong | Good if your app can spawn a stdio MCP process |
| ChatGPT Developer Mode | Remote only | Not direct today | Requires HTTP or SSE MCP server |
| Anthropic Messages API MCP connector | Remote only | Not direct today | Requires public HTTP/SSE MCP server |
SecureMCP-Lite currently supports:
- local stdio transport
- local child process target servers
It does not currently expose:
- Streamable HTTP transport
- SSE transport
- remote-hosted MCP endpoints
That is why local-first clients are the primary target in 0.1.0.
