Rafter is a hosted MCP server that gives your whole team one shared brain across the AI tools you already use. Capture how your team actually solves tasks — as memories, skills and agents — and every teammate's Claude, Cursor or ChatGPT session starts with that context instead of a blank slate.
https://app.heyrafter.xyz/api/mcpRemote server, Streamable HTTP transport, OAuth 2.1 sign-in (browser flow, dynamic client registration — no API keys to paste).
Claude Code
claude mcp add --transport http rafter https://app.heyrafter.xyz/api/mcpClaude Desktop / claude.ai — Settings → Connectors → Add custom connector → paste https://app.heyrafter.xyz/api/mcp.
Cursor — add to ~/.cursor/mcp.json:
{
"mcpServers": {
"rafter": { "url": "https://app.heyrafter.xyz/api/mcp" }
}
}ChatGPT — Settings → Connectors → enable Developer mode → Create a connector with the same URL.
Anything else that speaks MCP — point it at the URL above; the server handles the OAuth dance.
First connection opens a browser sign-in (Google, GitHub or email) and a consent screen scoped to one of your workspaces.

Tool | What it does |
| Full-text + entity search across your workspace's memories, skills and agents |
| Fetch one artifact with its graph edges ( |
| Write a durable team learning back from any session |
| Create or update a skill / agent / memory (versioned) |
| Read, browse and remove artifacts |
| Set up shared spaces |
| Bring the team in, manage roles |
| Current user + workspace context |
Artifacts are versioned, and [[wiki links]] between them resolve into a real graph — so fetch returns not just the document but what it cites and what cites it.
Stop repeating yourself: decisions, conventions and gotchas written once, recalled in every teammate's session.
Turn one person's workflow into everyone's skill: capture the steps that worked, run them from any MCP client.
Onboarding: new teammate connects, asks "how do we do X here", gets the team's actual answer.
Two ready-to-use files make your AI actually use the shared brain instead of guessing:
skill/SKILL.md — a Claude Code skill: drop it into .claude/skills/rafter/SKILL.md in your project (or ~/.claude/skills/rafter/) and your agent searches Rafter before answering "how do we do this" questions, and writes learnings back.
examples/startup-prompt.md — a startup prompt to paste into any tool's project/system instructions for the same behavior without skill support.
