Use hirestreamers from Claude, ChatGPT or any MCP client.

claude mcp add --transport http hirestreamers https://hirestreamers.com/api/mcp --header "Authorization: Bearer hs_pat_…"

Then run /mcp in Claude Code to check it connected.

{
  "mcpServers": {
    "hirestreamers": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://hirestreamers.com/api/mcp",
        "--header",
        "Authorization:${HS_AUTH}"
      ],
      "env": {
        "HS_AUTH": "Bearer hs_pat_…"
      }
    }
  }
}

Uses the mcp-remote bridge (needs Node.js) to send your token. Restart Claude Desktop after saving. Custom connectors in Claude's settings sign in with OAuth, which we are adding next.

import Anthropic from "@anthropic-ai/sdk";

const client = new Anthropic();
const response = await client.beta.messages.create({
  model: "claude-opus-5-5",
  max_tokens: 16000,
  betas: ["mcp-client-2025-11-20"],
  mcp_servers: [
    {
      type: "url",
      url: "https://hirestreamers.com/api/mcp",
      name: "hirestreamers",
      authorization_token: process.env.HS_TOKEN,
    },
  ],
  tools: [{ type: "mcp_toolset", mcp_server_name: "hirestreamers" }],
  messages: [{ role: "user", content: "Find open T2 briefs in English over $150." }],
});

Your own app calls the tools on your behalf; keep the token in a server-side secret.

ChatGPT connectors (developer mode) add a remote MCP server by URL and sign in with OAuth, which we are adding next. Until then, use the OpenAI Responses API's MCP tool, which can send the header:

{
  "type": "mcp",
  "server_label": "hirestreamers",
  "server_url": "https://hirestreamers.com/api/mcp",
  "headers": { "Authorization": "Bearer hs_pat_…" },
  "require_approval": "always"
}

Point it at https://hirestreamers.com/api/mcp with the bearer header. The server is stateless and answers in JSON (no SSE stream, no session id). Quick check from a terminal:

curl -s https://hirestreamers.com/api/mcp \
  -H "Authorization: Bearer hs_pat_…" \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"whoami","arguments":{}}}'
