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 ascension-mcp https://ascension.fyi/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 ascension-mcp --url https://ascension.fyi/mcp

Cursor

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

Gemini CLI configuration
gemini mcp add --transport http ascension-mcp https://ascension.fyi/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.
Claude Desktop configuration
