Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http testsy-mcp https://app.testsy.dev/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add testsy-mcp --url https://app.testsy.dev/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable testsy-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "testsy-mcp": {
      "url": "https://app.testsy.dev/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).

Cline configuration

{
  "mcpServers": {
