OpenCode
Give OpenCode real-time web search, content extraction, and citation-backed research through the You.com MCP Server.
Quick setup
Add You.com to your OpenCode config
Edit ~/.config/opencode/opencode.json (or your project-local opencode.json) and add:
This uses the free tier — 100 web searches per day, no signup.
Higher rate limits + full toolset
For unlimited queries plus you-contents (page extraction) and you-research (citation-backed deep research):
Get a key at you.com/platform.
Local install (stdio)
If you’d prefer to run the MCP server locally:
Omit YDC_API_KEY for free-tier behavior.
Quick demo
Troubleshooting
Server doesn't load
Check opencode.json is valid JSON. OpenCode silently skips invalid MCP entries.
spawn npx ENOENT
For local installs, install Node.js 18+ and ensure npx is on your PATH.
401 errors
Verify the Authorization header is exactly Bearer YDC-... with one space.
Tool calls fail with no error
Check OpenCode’s logs (opencode --debug) for MCP server errors. Most failures are config-format mismatches.
