## Description

Open the GBrain owner dashboard, manage MCP clients and permissions, or connect a native OAuth harness. Distinguishes owner administration from ordinary MCP access.

# MCP access and administration

Use [MCP administration](https://github.com/garrytan/gbrain/blob/master/docs/mcp/ADMIN.md) for the exact commands and
recovery table, [hosted setup](https://github.com/garrytan/gbrain/blob/master/docs/guides/hosted-harness-access.md) for
client installation, and [deployment](https://github.com/garrytan/gbrain/blob/master/docs/mcp/DEPLOY.md) for the running
service. If this skill is loaded remotely without those files, use
https://raw.githubusercontent.com/garrytan/gbrain/master/docs/mcp/ADMIN.md.
No local brain initialization or personal-agent bootstrap is required to
administer an existing server.

## Contract

Inspect the user's supplied endpoint and available configuration. A hosting
harness may administer its own server only when it has that server's owner
credential. A remote administrator needs the same separately supplied authority.
An ordinary MCP OAuth token, client secret, `admin` scope, or full tool surface
does not authorize dashboard login or client management.

Use `gbrain://capabilities` for effective MCP access and administration guidance
when available. Its admin URL is orientation, not a login. Without owner
authority, provide the exact owner-side command and prerequisite instead of
trying successively broader OAuth scopes. Name the server-hosting or authorized
administrator harness in the handoff, rather than asking an arbitrary agent.

## Owner actions

Commands run against the **existing** server with `gbrain mcp admin … --url URL`.
Use `--admin-token-file PRIVATE_FILE`, or the protected
`GBRAIN_ADMIN_BOOTSTRAP_TOKEN` environment variable. Do not print their values.
This HTTP path uses the live database connection; do not open a second PGLite
process, delete its lock, or start another server to obtain administration.
