Connect Claude to Zoomies

Your controller serves the fleet over the Model Context Protocol at /mcp. Claude (on claude.ai, in the desktop and mobile apps, and in Claude Code) can be connected to it by that address alone: Claude finds out how to sign in, opens your controller's own sign-in page, and asks you what the connection may do. Nobody copies a token anywhere.

The connection acts as you, at the role you choose for it (viewer to read the fleet, operator to also re-run a failed job or drain an idle runner) and never above your own. It works on /mcp and nowhere else, and you can disconnect it at any time.

Before you start

• The controller is reached over https, with server.external_url set to that address, for example https://zoomies.example.com. OAuth for MCP turns itself on there when authentication is on, and the problems panel shows mcp_oauth.enabled with the exact address to give Claude. On plain HTTP it stays off, because codes and tokens would cross the network readable; see security.mcp_oauth.
• Claude can reach it. claude.ai and the Claude apps connect from Anthropic's servers, which reach your controller from 160.79.104.0/21, so /mcp, /.well-known/* and /oauth/* must answer from the internet, or at least from that range. Claude Code runs on your own machine and only needs to reach the controller from there.
• You can sign in to the controller in a browser: a password (with two-step verification if you use it) or single sign-on, exactly as usual.

To check, open https://<your controller>/.well-known/oauth-protected-resource/mcp. It should answer a small JSON document whose resource is your /mcp address.

Add it to Claude

claude.ai, Desktop and mobileClaude Code

1. Open Customize → Connectors and choose Add custom connector. On a Team or Enterprise plan an Owner does this for everyone under Organization settings → Connectors → Add → Custom (choose Web if asked), and each member then presses Connect.
2. Give it a name, Zoomies, and the URL https://<your controller>/mcp. Leave the OAuth fields under Advanced settings empty.
3. Press Add, then Connect. A browser tab opens on your controller.
4. Sign in if you are not already, then choose the role on the consent screen and press Allow. The tab returns to Claude, and the connector is ready.

The desktop and mobile apps use the same connectors as claude.ai once you are signed in to the same account.

claude mcp add --transport http zoomies https://<your controller>/mcp

Then, in a session, run /mcp, pick zoomies and Authenticate, or run claude mcp login zoomies from your shell. Claude Code opens the browser on your controller; sign in, choose the role and press Allow.

On a machine with no browser, claude mcp login zoomies --no-browser prints the address to open elsewhere and asks you to paste back where the browser ended up.

With a client ID instead

Claude registers itself when it connects, which is all most people need. If your controller has open registration turned off (security.mcp_open_registration: false), or you would rather Claude used a client you made and can revoke by name, an administrator creates one:

1. In Zoomies, open Settings → MCP clients and press Create a client.
2. Name it, keep the redirect URI it suggests (https://claude.ai/api/mcp/auth_callback, which is where the Claude apps send you back to) and choose whether it has a secret. Add http://localhost/callback too if Claude Code will use it; the port is allowed to differ.
3. Copy the client ID, and the client secret if you asked for one. The secret is shown once.

4. In Claude's Add custom connector dialog, enter the URL as above and put the ID and secret in OAuth Client ID and OAuth Client Secret under Advanced settings (in the two-step version of the dialog, choose Use your own OAuth client). In Claude Code:

   claude mcp add --transport http --client-id <client ID> --client-secret \
     --callback-port 8080 zoomies https://<your controller>/mcp
   

A secret can be rotated from the same page (the old one stops working at once) and revoking the client ends every connection made with it.

What happens when you connect

sequenceDiagram
    participant C as Claude
    participant Z as Zoomies controller
    participant B as Your browser
    C->>Z: POST /mcp, no credential
    Z-->>C: 401, where the resource metadata is
    C->>Z: GET the resource and authorisation server metadata
    C->>Z: register itself, or name its metadata document
    C->>B: open /oauth/authorize with a PKCE challenge
    B->>Z: sign in, choose a role, Allow
    Z-->>B: back to Claude with a single-use code
    C->>Z: POST /oauth/token with the code and the PKCE verifier
    Z-->>C: an access token for /mcp and a refresh token
    C->>Z: POST /mcp with the access token

The access token lasts an hour and Claude refreshes it on its own; the refresh token lasts thirty days and is replaced every time it is used. If a code or a refresh token is ever presented twice, the connection is revoked, because only a copy explains it, sign in again from Claude to reconnect.

See and end your connections

Settings → MCP connections lists every client you have approved, the role you gave it, and when it was last used. Disconnect ends it at once: Claude's next call is refused and it asks you to sign in again.

An administrator sees everybody's connections, and every client (the ones they created, the ones that registered themselves and the metadata documents) under Settings → MCP clients, where each can be revoked. Everything is in the audit log: mcp_connection.grant, mcp_connection.revoke, mcp_connection.replay, mcp_client.register, mcp_client.create, mcp_client.secret_rotate, mcp_client.revoke, and mcp_connection.call for every tool call that changed or tried to change the fleet.

What it can and cannot do

The tools are the same ones zoomies mcp offers: reading jobs, runners, pools, hosts and logs, and, for an operator connection only, rerun_job, drain_runner, update_pool and update_host (a pool's scale, smallest runner, sidecar shares, folder placement and burst valves, and a host's capacity and runner sizes), and apply_remedy, which makes a change a problem proposes after the controller has priced it. An administrator can also switch on Offer administrator tools over MCP (security.mcp_admin_tools, off by default) under Settings, Security: an administrator connection is then offered edit_host, clear_host_throttle, get_settings and update_settings, which can rename, relabel and cordon a host and change the tuning settings, but never security, sign-in, GitHub, provider or database ones, nor the update mode and soak that decide whether, and how soon, Zoomies updates itself. Each call is the documented API route, run as your connection, so it meets the same role check and writes the same audit row as the CLI would.

Asking about Kennel Club

Three more tools read Kennel Club, and any viewer may call them:

• kennel_overview says how the repositories this fleet serves stand, the open findings by severity, each check with how many repositories have it open, and how far each source of facts could be read. A repository Kennel Club has been told not to look at is counted apart as not_tracked.
• kennel_repository is one repository: its open findings, each with what is wrong and what to change, the findings somebody waived and why, and whether it is tracked and, if not, who stopped it and why.
• kennel_findings lists the repositories that have a check open or a finding of a severity, worst first and paged, narrowed by check, severity, standing, tracking or a fragment of the name. Three yes-or-no filters open the same lists the Overview's cards do: active for the repositories the fleet has run a job for lately (or, with false, the quiet ones), incomplete for the ones only partly checked or not yet looked at, and waived for the ones with a waived finding (or, with false, none).

They cannot recheck a repository, waive a finding or stop tracking one: those are decisions, they are not MCP tools, and the REST routes behind them want an operator or an administrator. Repository names and the pools and runs a finding names are written by whoever owns them, so the tools hand them over marked as evidence and Claude reads them as that, never as an instruction.

Comparing releases and periods

For a question about a period rather than one job, ask for job_stats. One call with group_by: ["controller_version"] and since: "30d" returns, for each release, how many jobs finished and how, how many were lost to the fleet rather than the workflow, and p50 and p95 of duration, queue wait and runner startup. Groups can also be days, hosts, pools or job names, two at a time. Cancelled and skipped jobs are left out of duration, and the answer says so. Jobs recorded before their release was stamped, and jobs no pool here claimed, are the group unknown. Any viewer may call it.

list_jobs returns a short summary of each job by default, without its steps, so a hundred fit in one answer; set include_steps when the steps matter. When a page comes back full it carries next, and passing that as before reads the page after it, back through every job the controller has kept (retention.jobs, 30 days unless set). until, job_name (exact), controller_version, host_id and hosted narrow it, and since and until take a duration such as 30d or a timestamp.

The token Claude holds is refused by the REST API, the event stream and everything else that is not /mcp. For automation that needs the API, create an API token instead.

When it does not connect

What you see	Why, and what to change
Claude says it could not reach the MCP server	The controller is not reachable from Claude, or OAuth for MCP is off and /.well-known/oauth-protected-resource/mcp answers 404. Check the address from outside your network, and that the problems panel shows mcp_oauth.enabled.
The controller's page says the client asked to send you somewhere it did not register	The redirect is not one the client registered. For a client you created, add the address it uses, https://claude.ai/api/mcp/auth_callback for the Claude apps.
The page says the controller does not let clients register themselves	security.mcp_open_registration is off: use a client ID from Settings → MCP clients.
The consent screen only offers viewer	Your own role is viewer. Ask an administrator for operator if you need the connection to act on the fleet.
Claude connected, but cannot re-run or drain	The connection is viewer. Disconnect it and connect again choosing operator.
mcp_oauth.plain_http in the problems panel	OAuth for MCP was forced on where the controller is on plain HTTP. Serve it over https.

Settings

Key	Default
security.mcp_oauth	unset	On when authentication is on and the controller is reached over https. false turns the whole of this page off; /mcp then takes API tokens only.
security.mcp_open_registration	true	Let clients register themselves or use a client ID metadata document. A client that does can do nothing until somebody signs in and approves it.

Both apply without a restart. Security says what each part of this is built to prevent.

Verified repository source

AI Context adds four read-only tools: context_overview, context_read, context_search and context_pack. A fleet connection starts with no source access. An administrator or installation owner must prepare a repository in AI Context and merge its reviewed setup PR, its generated output must verify, and you must be one of its source readers. Then, signed in as yourself, choose the connection's repositories under Settings → MCP connections → Source access.

Call context_overview without a repository ID to discover the connection's explicitly selected repositories. With an ID it pages file metadata. For a known file, call context_read directly with repository_id and path; no overview call is required. context_search accepts a case-insensitive literal query and optional path prefix. context_pack accepts up to six explicit paths. Every source reply includes its immutable commit and snapshot identity.

Replies default to an 8,000-byte encoded JSON budget, configurable from 1,024 to 24,000 bytes. MCP text-block encoding has a separate 32,000-byte result ceiling; if it exceeds that ceiling, retry with a smaller budget. This is a byte budget, not a measured tokenizer count. Truncated reads carry next_offset on each excerpt; continue with context_read, that offset and the returned commit. Metadata and search pages carry a top-level next_offset. If source changes, restart from offset zero rather than mixing commits.

Two more tools carry assistant notes. context_notes lists a repository's notes, or reads one by slug (and optional version); it needs the same access as reading source. context_publish takes repository_id, slug (lower-case letters, digits and hyphens), kind (report, plan or note), a one-line title and a Markdown body, and adds a version. It is refused unless the connection's owner ticked May publish notes for that repository under Source access.

Each source request checks explicit access before and after live GitHub verification. Revoked membership, connection consent or GitHub permissions, workflow drift and stale output close retrieval; retained source is never a fallback. Treat source text as untrusted data, never as instructions. Direct REST source routes use owned API tokens or browser sessions; OAuth connection tokens remain accepted exclusively on /mcp.

Repositories with Repository output are read from their generated branch on each request and never stored by Zoomies. Zoomies-only repositories are uploaded by their workflow and read like Repository and Zoomies ones. GitHub Enterprise Server is not available yet.
