GitHub Copilot CLI

View as MarkdownOpen in Claude

The You.com plugin for GitHub Copilot CLI installs four skills and the You.com MCP servers from the agent-skills repo. The MCP servers give Copilot tools such as you-search, you-contents, you-research, and you-finance. The skills tell it when to use each one and how to cite what it finds.

Install the Docs MCP server

The Docs MCP server lets your agent search over the entirety of these docs. Free to use.

Install https://you.com/docs/_mcp/server. See the Docs MCP Server guide to learn more.

Install the Plugin

1

Add the Marketplace and Install

copilot plugin marketplace add youdotcom-oss/agent-skills
copilot plugin install you@you-com

Inside a Copilot CLI session, run the same commands as /plugin marketplace add youdotcom-oss/agent-skills and /plugin install you@you-com.

2

Sign In

The you, you-research, and you-finance servers sign in with your You.com account over OAuth. If /mcp lists one as needing auth, run /mcp auth <server-name>, such as /mcp auth you, to open the browser sign-in.

3

Try It

Use you-web to find what's new in the latest TypeScript release, with sources.

What the Plugin Installs

MCP servers. Run /mcp to see them:

ServerEndpointAuth
youhttps://api.you.com/mcpOAuth
you-researchhttps://api.you.com/mcp/researchOAuth
you-financehttps://api.you.com/mcp/financeOAuth
you-discoverhttps://api.you.com/mcp?profile=discoverNone

Skills.

SkillUse it for
you-webCurrent web search and URL reading, with sources cited. Switches to keyless you-search when no credentials are set.
you-researchChoosing between agent-led searching and a single cited you-research call
you-financeFinance questions through the you-finance tool
you-discoverFinding the right You.com API, MCP server, or SDK for a project you’re building

Use the MCP Server Without the Plugin

To add only the tools, without the skills, add the You.com MCP server with copilot mcp add. The CLI writes it to ~/.copilot/mcp-config.json.

Free profile (you-search and you-discover, 100 queries per day, no account):

copilot mcp add --transport http you-com "https://api.you.com/mcp?profile=free"

API key. Get a key at you.com/platform:

copilot mcp add --transport http you-com https://api.you.com/mcp \
  --header "Authorization: Bearer <YDC_API_KEY>"

Troubleshooting

Inside a Copilot CLI session, refresh the marketplace with /plugin marketplace update you-com, then retry /plugin install you@you-com.

Run copilot plugin list to confirm you is installed. If it’s disabled, run copilot plugin enable you, then start a new session.

If you added the MCP server by hand before installing the plugin, remove the manual entry with /mcp delete you-com.
