Connect OpenCode to Rafter’s MCP server
OpenCode takes remote MCP servers natively — no bridge, no API key. One block in opencode.json and its agent can search your team's shared memory, follow its skills, and write learnings back.
Add Rafter to opencode.json
Add this
mcpentry toopencode.jsonin your project root. OpenCode reads a global config too, if you would rather have Rafter everywhere.{ "$schema": "https://opencode.ai/config.json", "mcp": { "rafter": { "type": "remote", "url": "https://app.heyrafter.xyz/api/mcp", "enabled": true } } }The "remote" type is what tells OpenCode this is a hosted HTTP server rather than a command to run.
Sign in and pick a workspace
OpenCode notices Rafter’s sign-in requirement on the first call and opens the browser itself. Pick the workspace to connect. You can also start it by hand with
opencode mcp auth rafter.Ask something your team already knows
Try “Check Rafter: how do we handle a new client?” — the answer comes from your team’s own memories and skills.
Your first five minutes
The connection is the easy part. The habit is what pays: make OpenCode check the shared brain before it improvises. Three things to try in OpenCode:
- “What do we know about [a client or project]?”Rafter’s search answers from your team’s actual notes — with what they cite.
- “How do we [something a teammate has done before]? Follow the skill if we have one.”Skills are the team’s way of doing it, taught once and reused.
- “Save this as a memory: [a decision you just made].”Written back with add_memory — versioned, searchable, there for the next person.
To make it automatic, paste this line into OpenCode’s project or system instructions:
Check Rafter first: search our skills and memories before you answer, and save anything durable back with add_memory.

Troubleshooting
Do I need an API key?
No. Rafter authenticates with OAuth in the browser, and OpenCode handles that flow for remote servers on its own — there is no token to paste or store in the config file.
Which workspace should I pick when signing in?
The one whose skills and memories you want this tool to see. A connection sees exactly what you can see — your teams and your role — never more. You can connect again later and grant a different workspace.
Is my team's content used to train AI models?
No. Rafter does not use your content to train generalized or foundation models — see the privacy policy.
