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 the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http freeastroapi-mcp https://api.freeastroapi.com/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 freeastroapi-mcp --url https://api.freeastroapi.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable freeastroapi-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "freeastroapi-mcp": {
      "url": "https://api.freeastroapi.com/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "freeastroapi-mcp": {

      "type": "http",
      "url": "https://api.freeastroapi.com/mcp"
    }
  }
}

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http freeastroapi-mcp https://api.freeastroapi.com/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
