v0 by Vercel

v0 is Vercel's AI-powered tool for generating React components and UI. Connect v0 to memories.sh to access your rules and context.

Setup

1. Get Your API Key

Sign up or log in at memories.sh/app
In the dashboard, find the MCP API Key section
Click Generate API Key
Copy the key (you won't see it again)

2. Configure v0

In v0's MCP settings, add:

{
  "mcpServers": {
    "memories": {
      "url": "https://memories.sh/api/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Replace YOUR_API_KEY with the key you generated.

3. Verify Connection

Test the connection:

curl -H "Authorization: Bearer YOUR_API_KEY" https://memories.sh/api/mcp
# Should return: {"status":"ok","name":"memories.sh MCP Server","version":"0.4.0"}

Using with v0

Once connected, v0 can access your memories:

Get context for a task:

Search my memories for React component patterns

Save new learnings:

Save this as a rule: "Use Tailwind's cn() helper for conditional classes"

Recall decisions:

What decisions have I made about design system components?

Available Tools

The hosted MCP server provides these tools:

Tool	Description
`get_context`	Get rules and relevant memories
`add_memory`	Store a new memory (rule, decision, fact, note)
`search_memories`	Search by content
`list_memories`	List recent memories

Syncing with CLI

Memories added via v0 sync to your cloud database. To access them locally:

# Login (if not already)
memories login

# Enable sync
memories sync enable

# Pull latest memories
memories sync pull

Now your memories are available both in v0 and your local CLI/IDE tools.

Managing Your API Key

In the dashboard:

Regenerate — Create a new key (invalidates the old one)
Revoke — Delete the key entirely

API keys are tied to your account. Anyone with your key can read and write to your memories.

Alternative: Local Server (Development)

For local development without cloud sync, you can run a local MCP server:

memories serve --sse --port 3030

Then configure v0 to connect to http://localhost:3030/mcp (no auth required for localhost).

Troubleshooting

401 Unauthorized

Check your API key is correct
Ensure the Authorization header includes Bearer prefix
Regenerate your key in the dashboard

No memories found

Verify you have memories: memories list
Check sync is enabled: memories sync status
Push local memories to cloud: memories sync push

v0 not using my rules

Make sure your rules are synced to the cloud:

memories sync push

Then verify in the dashboard that your rules appear.
