## Which one, for what

### Functionize MCP server (E)

Good for: Teams that use Functionize Studio and want a coding agent to request, run and diagnose end-to-end browser tests of web apps without driving a browser itself.

Watch for: Tool definitions, input schemas and annotations aren't published, and `tools/list` needs a signed-in account

### Notte (B)

Good for: Teams that want hosted browsers together with agents, vaults for logins, personas with mailboxes and scheduled browser functions behind one key.

Ahead on:
- Reliability, 58 against 50
- Schema & documentation, 74 against 29
- Agent ergonomics, 75 against 43
- Payments & pricing, 40 against 30
- Maintenance & community, 83 against 49

Watch for: status.notte.cc shows the Scrape API down on 15 of 90 days (about 6 hours in total) and CAPTCHA solving at 88.9 per cent availability

## Verdicts

**Functionize MCP server.** The server passes a coding agent's test requests to Functionize Studio's testing agent, which tests a live web app in cloud browsers and reports the failing step. It uses OAuth with read and write scopes and has a no-card free plan. Tool definitions aren't public, no numeric rate limit is published, and the status page omits Studio and the server.

**Notte.** Notte publishes an OpenAPI 3.1 contract for 100 operations, a hosted MCP server with eight tools and OAuth, and a free plan with $10 of credits and no card. Its status page records about six hours of Scrape API downtime in 90 days, and a bot check blocked our read of the terms and privacy policy.

## Before you call either

### Functionize MCP server

1. Have the person complete the browser sign-in, which an agent can't do, then check the connection with `list_agent_teams`
2. Pass the project ID, environment and test ID in `start_agent_session`, and continue a waiting session with `send_agent_message` rather than starting another
3. Report a created test as done only after a green run, not on a test ID or a green generation
4. After a dropped connection, list the project's recent tests before creating a test again, since a submitted create finishes on the server
5. Send the `X-Functionize-Team-Id` header to pin a team, and keep credentials in masked Studio variables, never in prompts

### Notte

1. Send `Authorization: Bearer $NOTTE_API_KEY` to https://api.notte.cc. A person creates the key in the console at console.notte.cc first
2. Stop every session when the task ends. Sessions close after 3 idle minutes or 15 minutes in total by default, and the Free plan caps a session at 15 minutes
3. Use https://api.notte.cc/mcp for browser work. Function and agent administration tools are only on https://api.notte.cc/mcp/full
4. Back off on 429 and on 529, which means the cluster has too many sessions. The SDKs do not retry rate limits for you
5. Download session replays within 24 hours. The recordings page says they are deleted after that
