Claude Code
Connect Part3 to Claude Code (CLI) in one command.
Claude Code is Anthropic's terminal-based AI coding assistant. Part3 ships a first-class MCP integration.
One-liner
claude mcp add --transport http part3 https://mcp.part3.ioNo header, no secret. On first use Claude Code opens a browser to the Part3 sign-in page, then to a consent screen where you approve the requested access. After that, tokens refresh automatically and you only re-authenticate every ~90 days.
Prime-only access
MCP is currently limited to users who are a Project Prime on at least one project, plus super-duper-admins. If you're not, the consent screen will show an access-denied page instead of completing the flow.
Settings file (alternative)
If you'd rather edit a config file, add this to .claude/settings.local.json
(per-project, gitignored) or ~/.claude/settings.local.json (global):
{
"mcpServers": {
"part3": {
"type": "url",
"url": "https://mcp.part3.io"
}
}
}No headers field — Claude Code discovers the OAuth endpoints automatically.
Verify
Restart Claude Code, then run /mcp. You should see part3 listed with its
available tools. Ask a question:
List my three most recent projects.
If Claude responds with a project list, you're wired up.
