feat: add an opt-in Parallel Search MCP example

[georgeatparallel]

Problem

If you want to search the web from bolt.diy, you need to find an MCP server and figure out how to connect it. There's no Parallel Search example in the app to help you get started, and it's easy to mistake Load Example for something that adds to your existing settings.

Solution

This adds Parallel Search to the existing Load Example config, plus a short walkthrough in the README. You can save just that connection, check that web_search and web_fetch are available, and use them in chat. No Parallel account or API key is needed.

Nothing connects automatically. Load Example only replaces the editor draft, and the instructions explain how to keep your other servers when saving. Your model choice and tool approvals stay the same. The guidance also explains what gets sent to Parallel when you approve a call, how to inspect the results, and that free search has rate limits. Model and hosting costs are separate.

This is for community bolt.diy, not hosted Bolt.new.

Testing

• Checked the settings flow in the browser, from an empty config through saving only Parallel and discovering both tools.
• Ran an anonymous search and fetch through bolt.diy's real MCP client and chat approval-processing path. Source URLs and excerpts came through in the results.
• All 59 tests pass, including saved-settings protection, approval and denial, and HTTP, RPC, and MCP tool errors. Lint, build, and post-build typecheck pass too.

A full model-generated conversation wasn't tested because the isolated app had no model credentials configured. GitHub's application, code-quality, security, PR-validation, and preview workflows still require maintainer approval.

I work at Parallel, which operates this service.
