Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

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

Claude Code configuration

claude mcp add --transport http xearno-tools-mcp https://xearno.tools/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 xearno-tools-mcp --url https://xearno.tools/mcp

Cursor

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

Cursor configuration

{
  "mcpServers": {
    "xearno-tools-mcp": {
      "url": "https://xearno.tools/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.

Cline configuration

{
  "mcpServers": {
    "xearno-tools-mcp": {
      "type": "streamableHttp",
      "url": "https://xearno.tools/mcp",
      "disabled": false
    }
  }
}

  "servers": {
    "xearno-tools-mcp": {
      "type": "http",
      "url": "https://xearno.tools/mcp"
