Platform Comparison
All 6 MCP Clients vs anonym.legal
Every platform supports all 7 MCP tools and 6 operators. The differences lie in transport protocol, config format, LLM flexibility, and setup complexity. This page breaks down every relevant difference.

Transport Protocols
Streamable HTTP (MCP 1.0)
Single POST https://anonym.legal/mcp endpoint. Supports both request-response and streaming via SSE in one connection.
- No local subprocess
- No Node.js required
- TLS 1.3 encrypted
- Works behind corporate firewalls
- Recommended for all cloud-connected setups
stdio (subprocess IPC)
The MCP server runs as a local subprocess. Communication via stdin/stdout pipes. Original MCP transport method.
- Requires Node.js + npx
- Subprocess starts with the client
- Works offline (local validation)
- Claude Desktop: only supports stdio
- Good for air-gapped environments
Config Format Differences
The biggest source of confusion when switching between platforms. Pay attention to the top-level key and how the server entry is structured:
{
"mcpServers": {
"anonym-legal": {
"command": "npx",
"args": ["-y", "@anthropic-ai/mcp-server-anonym-legal"],
"env": {"ANONYM_LEGAL_API_KEY": "YOUR_KEY"}
}
}
}
{
"mcpServers": {
"anonym-legal": {
"url": "https://anonym.legal/mcp",
"headers": {"Authorization": "Bearer YOUR_KEY"}
}
}
}
{
"servers": {
"anonym-legal": {
"type": "http",
"url": "https://anonym.legal/mcp",
"headers": {"Authorization": "Bearer YOUR_KEY"}
}
}
}
{
"mcpServers": [
{
"name": "anonym-legal",
"transport": {
"type": "streamableHttp",
"url": "https://anonym.legal/mcp",
"requestOptions": {"headers": {"Authorization": "Bearer YOUR_KEY"}}
}
}
]
}
Which Platform Should I Use?
| Use Case | Recommended Platform | Why |
|---|---|---|
| Non-technical users / simplest setup | Claude Desktop | One config file, no HTTP setup, Anthropic's reference implementation |
| Developer coding workflows | Cursor | Best AI IDE experience, per-project config, HTTP is zero-friction |
| VS Code power users (already using Copilot) | VS Code + Copilot | Stays in existing IDE, Copilot Agent mode is powerful |
| Multi-LLM workflows (Claude + GPT + Gemini) | Windsurf or Continue | Both support multiple LLM providers per session |
| Autonomous/agentic coding tasks | Cline | Designed for autonomous multi-step tasks with tool use |
| Open-source preference | Continue or Cline | Both are fully open-source, self-hostable configs |
| JetBrains IDE users | Continue | Only major MCP client with native JetBrains support |
| Air-gapped / offline setup | Claude Desktop (stdio) | stdio subprocess runs locally; install npm package globally for offline |
Key Gotchas & Differences
VS Code uses "servers" — not "mcpServers"
This is a breaking difference. Every other client uses "mcpServers" as the top-level config key. VS Code uses "servers". Copying config from Cursor to VS Code will silently fail.
Claude Desktop is stdio-only
Claude Desktop does not support HTTP transport. You must use the npx subprocess method. This requires Node.js to be installed on the machine.
Continue uses an array for mcpServers
Continue's config format uses an array: "mcpServers": [{ ... }] — not an object like Cursor/Claude Desktop. You also need to specify a "transport" object with a "type" field.
VS Code requires "type" field for each server
Unlike Cursor which infers the transport type from the presence of a "url" vs "command", VS Code requires an explicit "type": "http" or "type": "stdio" field in each server entry.
Windsurf and Cline prefer UI configuration
Both Windsurf and Cline are designed to configure MCP servers through their UI — not raw JSON files. This is simpler for setup but less portable for team sharing.
