GitHub Copilot

LNAI exports unified configuration to GitHub Copilot’s native formats, including repository instructions, path-specific rules, and MCP servers.

Generated mcp.json

MCP servers are exported to .vscode/mcp.json with transformations:

// Input (LNAI format)
{
  "mcpServers": {
    "database": {
      "command": "npx",
      "args": ["-y", "@example/db"],
      "env": { "DB_URL": "${DB_URL}" }
    }
  }
}

// Output (Copilot format in .vscode/mcp.json)
{
  "inputs": [],
  "servers": {
    "database": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@example/db"],
      "env": { "DB_URL": "${env:DB_URL}" }
    }
  }
}

Stdio Servers

LNAI	Copilot
`${VAR}`	`${env:VAR}`
Stdio implicit	`type: "stdio"` explicit

HTTP/SSE Servers

// Input (LNAI format)
{
  "mcpServers": {
    "api": {
      "type": "http",
      "url": "https://api.example.com/mcp",
      "headers": { "Authorization": "Bearer ${TOKEN}" }
    }
  }
}

// Output (Copilot format)
{
  "inputs": [],
  "servers": {
    "api": {
      "url": "https://api.example.com/mcp",
      "requestInit": {
        "headers": { "Authorization": "Bearer ${env:TOKEN}" }
      }
    }
  }
}

LNAI	Copilot
`type: "http"`	`url` field only (no type)
`type: "sse"`	`url` field only (no type)
`headers: {}`	`requestInit: { headers: {} }`

Rules Transformation

Rules are transformed from .md to .instructions.md format with YAML frontmatter:

paths:

- "\*_/_.ts"
- "\*_/_.tsx"

LNAI Field	Copilot Field	Notes
`paths`	`applyTo`	Joined with comma
(first H1)	`description`	Extracted from content
(empty paths)	(no applyTo)	Rule applies globally

Unsupported Features

Feature	Status	Notes
Permissions	⚠️ Ignored	Copilot does not support permissions
Non-MCP overrides	⚠️ Ignored	Only `mcpServers` is supported in JSON overrides

LNAI will display warnings when unsupported features are configured.

Overrides

Place Copilot-specific files in .ai/.copilot/ to have them symlinked to .github/:

.ai/.copilot/
└── workflows/
    └── custom.yml → .github/workflows/custom.yml

When an override file exists at the same path as a generated file, the override takes priority.
