AI agent support¶

The live MCP gateway is a standard, public, read-only MCP server, so any MCP-capable agent can connect to it. This page lists the popular clients, the exact configuration each one needs, and what has been verified against the hosted endpoint.

The endpoint is:

https://hkex-listco-updates.ascent-partners.com/api/mcp

There is no authentication and no API key — connect anonymously. The transport is Streamable HTTP with JSON-RPC 2.0. A browser GET returns 405 Method Not Allowed by design (the endpoint offers no server-sent-events stream); if a client only offers an "SSE" transport, choose "Streamable HTTP" where the client allows it, or bridge through mcp-remote.

Compatibility¶

Client	Transport	Status
opencode	Streamable HTTP (remote)	Verified live
Claude Code	Streamable HTTP (`--transport http`)	Supported
Claude Desktop	Remote connector, or `mcp-remote` stdio bridge	Supported
ChatGPT	Developer-mode custom connector	Supported
Cursor	Streamable HTTP (`url`)	Supported
VS Code (GitHub Copilot)	Streamable HTTP (`type: "http"`)	Supported
Gemini CLI	Streamable HTTP (`httpUrl`)	Supported
Manus	Custom MCP server (Streamable HTTP)	Supported
Perplexity	Custom remote connector (Streamable HTTP)	Supported
Any MCP SDK client	Streamable HTTP	Verified live (official Python SDK)
Any stdio-only client	`mcp-remote` bridge	Verified live

"Verified live" means the handshake, tools/list, and a tool call were exercised against the hosted endpoint. "Supported" clients speak the same standard Streamable HTTP transport; only the configuration differs.

Claude Code¶

claude mcp add --transport http hkex-live \
  https://hkex-listco-updates.ascent-partners.com/api/mcp

Or commit a project-scoped .mcp.json (a url entry requires a type):

{
  "mcpServers": {
    "hkex-live": {
      "type": "http",
      "url": "https://hkex-listco-updates.ascent-partners.com/api/mcp"
    }
  }
}

Claude Desktop¶

Add the server under Settings → Connectors → Add custom connector and paste the endpoint URL. Alternatively, bridge it as a local stdio server in claude_desktop_config.json:

{
  "mcpServers": {
    "hkex-live": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://hkex-listco-updates.ascent-partners.com/api/mcp"]
    }
  }
}

ChatGPT¶

Enable developer mode, then Settings → Connectors → Advanced → Developer mode → Add custom connector and paste the endpoint URL as a remote MCP server.

Cursor¶

Add to ~/.cursor/mcp.json (or the project .cursor/mcp.json):

{
  "mcpServers": {
    "hkex-live": {
      "url": "https://hkex-listco-updates.ascent-partners.com/api/mcp"
    }
  }
}

VS Code and GitHub Copilot¶

Add to .vscode/mcp.json (workspace) or the user profile mcp.json:

{
  "servers": {
    "hkex-live": {
      "type": "http",
      "url": "https://hkex-listco-updates.ascent-partners.com/api/mcp"
    }
  }
}

Gemini CLI¶

Add to ~/.gemini/settings.json (Streamable HTTP uses httpUrl; url is the deprecated SSE form):

{
  "mcpServers": {
    "hkex-live": {
      "httpUrl": "https://hkex-listco-updates.ascent-partners.com/api/mcp"
    }
  }
}

opencode¶

Add to opencode.json (global or project):

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "hkex-live": {
      "type": "remote",
      "url": "https://hkex-listco-updates.ascent-partners.com/api/mcp",
      "enabled": true
    }
  }
}

Manus¶

In Manus, open Settings → Integrations → Custom MCP Servers → Add Server, then provide the server name, the endpoint URL, and the transport (Streamable HTTP). Manus verifies the connection and lists the tools.

Perplexity¶

In Perplexity, open the connector settings and choose Add custom remote connector, then set the URL to the endpoint, the transport to Streamable HTTP, and the authentication to None.

stdio-only clients¶

If a client can only launch local stdio servers, bridge the gateway with mcp-remote:

{
  "mcpServers": {
    "hkex-live": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://hkex-listco-updates.ascent-partners.com/api/mcp"]
    }
  }
}

For a stored corpus (rather than live fetches), use the stdio MCP server instead, which reads from a configured database sink.

Protocol details¶

Transport — Streamable HTTP, POST with JSON-RPC 2.0; OPTIONS answers CORS preflight; other methods return 405 with Allow: POST.
Protocol versions — 2024-11-05, 2025-03-26, 2025-06-18, and 2025-11-25 are negotiated with the version the client requests; anything else falls back to 2024-11-05.
Capabilities — tools only. Probes for resources/list, resources/templates/list, and prompts/list return empty lists so probing clients connect cleanly.
Origin — a web Origin must be allowlisted (MCP's DNS-rebinding mitigation). Desktop shells that send no Origin, null, or a file:// origin are allowed.
Tools — get_server_info, search_filings, and get_filing; all read-only.
