## Before you call it

1. Point the AWS SDK at https://t3.storage.dev with region `auto`; the stdio MCP README still shows the older fly.storage.tigris.dev endpoint
2. Ask for an access key with a ReadOnly or ReadWrite role on one bucket rather than an org-wide key
3. Keep presigned URLs short; Tigris accepts up to 90 days
4. Don't call tigris_list_objects on a large bucket; it walks every object with no limit or prefix
5. Use @tigrisdata/iam 2.6.0 or later before writing policies with conditions

## Connect

```bash
AWS_ACCESS_KEY_ID=$TIGRIS_ACCESS_KEY_ID AWS_SECRET_ACCESS_KEY=$TIGRIS_SECRET_ACCESS_KEY \
  aws s3 cp ./hello.txt s3://my-bucket/hello.txt \
  --endpoint-url https://t3.storage.dev --region auto
```

```bash
claude mcp add --transport http tigris https://mcp.storage.dev/mcp --scope user
```
