VS Code
Connect Part3 to VS Code's built-in MCP support (GitHub Copilot Chat agent mode).
VS Code has built-in MCP support — generally available since the v1.102 (June 2025) release. GitHub Copilot Chat in agent mode can call MCP servers directly. The Part3 MCP server connects with no custom code or extension.
Add the MCP server
Open the Command Palette (Cmd/Ctrl + Shift + P) → MCP: Add Server, choose HTTP, and paste:
https://mcp.part3.ioWhen prompted, pick Workspace (stores the entry in .vscode/mcp.json) or
Global (your user profile). The workspace file looks like:
{
"servers": {
"part3": {
"type": "http",
"url": "https://mcp.part3.io"
}
}
}No header, no secret. VS Code discovers the OAuth endpoints automatically and opens a browser on first use to sign in and approve access.
Prime-only access
MCP is currently limited to users who are a Project Prime on at least one project, plus super-duper-admins. Non-Primes will see an access-denied page on the consent screen.
Use it
Open Copilot Chat and switch to Agent mode (the dropdown in the chat
input). Tools from part3 will appear under the tools picker. Ask:
Using Part3, list my active projects.
