Agents and self-hosted apps

VGC Teambuilder is a remote MCP server at this address, using the Streamable HTTP transport with no sign-in:

https://api.pokemcp.com/mcp

None of the apps on this page has been tested with VGC Teambuilder yet; the steps follow each project’s own documentation. The code examples at the end have been tested. If something doesn’t connect, see Troubleshooting.

OpenClaw

openclaw mcp add vgc-teambuilder --url https://api.pokemcp.com/mcp --transport streamable-http
openclaw mcp doctor vgc-teambuilder --probe

Keep --transport streamable-http: without it, OpenClaw uses the older SSE transport, which won’t connect. You can also add it in the Control UI under Settings → MCP, or in the config file:

{ mcp: { servers: { "vgc-teambuilder": { url: "https://api.pokemcp.com/mcp", transport: "streamable-http", enabled: true } } } }

Hermes Agent

Add this to ~/.hermes/config.yaml, then run /reload-mcp or restart Hermes:

mcp_servers:
  vgc_teambuilder:
    url: "https://api.pokemcp.com/mcp"

Don’t set transport: sse or auth: oauth; the defaults are right.

Goose

Add to Goose

Or run goose configure, choose Add Extension and then Remote Extension (Streamable HTTP). In ~/.config/goose/config.yaml:

extensions:
  vgc-teambuilder:
    name: VGC Teambuilder
    type: streamable_http
    uri: https://api.pokemcp.com/mcp
    enabled: true
    timeout: 300

LM Studio

Needs LM Studio 0.3.17 or later. Add to LM Studio, or open the Program tab in the right sidebar, choose Install → Edit mcp.json and add:

{ "mcpServers": { "vgc-teambuilder": { "url": "https://api.pokemcp.com/mcp" } } }

Open WebUI

Needs Open WebUI 0.6.31 or later, and an administrator account.

1. Open Admin Settings → Integrations → External Tool Servers and choose Add Connection.
2. Set Type to MCP (Streamable HTTP). Choosing OpenAPI instead breaks the form.
3. Enter the address above and set Authentication to None.

LibreChat

In librechat.yaml, then restart LibreChat:

mcpServers:
  vgc-teambuilder:
    type: streamable-http
    url: https://api.pokemcp.com/mcp
    requiresOAuth: false

From your own code

Tested with the official TypeScript SDK (version 1) and the official Python SDK (versions 1 and 2).

TypeScript (@modelcontextprotocol/sdk):

import { Client } from "@modelcontextprotocol/sdk/client/index.js";
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp.js";
 
const client = new Client({ name: "my-app", version: "1.0.0" });
await client.connect(new StreamableHTTPClientTransport(new URL("https://api.pokemcp.com/mcp")));
const result = await client.callTool({ name: "get_top_usage", arguments: { limit: 5 } });

Python (mcp 2.x):

import asyncio
from mcp import Client
 
async def main():
    async with Client("https://api.pokemcp.com/mcp") as client:
        result = await client.call_tool("get_top_usage", {"limit": 5})
        print(result)
 
asyncio.run(main())

Every request is a POST. There is no session to keep and no event stream to open. Clients must send Accept: application/json, text/event-stream. The Tools page lists every tool and its parameters.
