Description

Add an opt-in Parallel Search MCP example for researching Unity APIs, package documentation, and troubleshooting sources. It provides free web search powered by Fast mode and page fetching without an account or API key. The guide shows how to add the HTTP server alongside unityMCP, and includes a runnable search-and-fetch client.

Type of Change

  • Documentation update
  • Test update

Changes Made

  • Add the web research guide and a standalone FastMCP configuration example.

Compatibility / Package Source

  • Unity version(s) tested: Not applicable; no Unity package changes.
  • Package source used: Repository checkout on beta.
  • Resolved commit hash from Packages/packages-lock.json: Not applicable.

Testing/Screenshots/Recordings

  • Not applicable (explain why in Additional Notes)

The example was exercised through its configuration loader against anonymous HTTP search and fetch. Focused request tests and the documentation build passed.

Documentation Updates

  • I have added/removed/modified tools or resources

Related Issues

None.

Additional Notes

Unity test suites do not apply to this standalone client example. The example makes direct MCP calls; it does not run an LLM or control the Editor. Anonymous access is rate-limited.

I work at Parallel.

Summary by CodeRabbit

📝 Walkthrough

Walkthrough

This change adds a configured Parallel Search MCP server and a standalone CLI that calls web_search and web_fetch. It adds network-free tests for successful requests and failure cases, plus documentation for configuring and using the integration.

The example works with its supplied configuration, but the CLI rejects a combined Unity and Parallel configuration. This is a bounded issue with a workaround.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Handle tool names in combined configurations.

If --config points to a configuration containing both unityMCP and parallel, FastMCP 3 prefixes the tools with their server names. The check on Line 19 then rejects parallel_web_search and parallel_web_fetch, although the Parallel server exposes both tools. Select the parallel server from the configuration before creating Client, or use the prefixed names for discovery and calls. The current test covers only the one-server configuration.
