MCP server · General-purpose
Give your assistant a cloud browser agent it can actually run.
A raw, unopinionated 1:1 mapping of the OpenHelm public API. Write custom instructions, spawn an ephemeral agent run in a browser sandbox, and read back evidence-backed structured JSON, all from ChatGPT, Claude or Cursor.

What it does
The general-purpose server exposes the OpenHelm /v1 engine directly to any MCP client. Instead of a fixed set of opinionated workflows, it gives your assistant the primitives: define a task in natural language, optionally pin a JSON output schema, run it in an isolated cloud browser sandbox, and retrieve structured, evidence-backed results.
It is the right server when you are building custom automations, prototyping in Cursor, or want full control over prompts and output shape rather than a domain-specific toolset.

Add the remote server
In ChatGPT, Claude, Cursor or any MCP client, add a remote connector pointing at https://mcp.openhelm.ai/main/mcp. No install, no terminal, no Node setup. For clients that need a local bridge, run npx mcp-remote https://mcp.openhelm.ai/main/mcp.

Connect your OpenHelm account
Click Connect and you are sent to app.openhelm.ai/connect to authorise via OAuth 2.1. Your encrypted OpenHelm API key is wrapped in a signed token, the server itself stores no secrets.

Add a card to start the trial
New accounts add a card to activate a 14-day free trial (you are not billed during the trial). This keeps the shared cloud compute protected from multi-account abuse.

Run tasks from your assistant
Ask your assistant in plain English. It calls the right tool, OpenHelm spins up an isolated cloud browser sandbox, and returns evidence-backed structured results, polling check_result for longer runs.
Prefer to call the engine directly from your own product? The same primitives are available over REST.
