Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@Token2OAuthadd a new bearer token to the credential pool"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
ROTOXY
One gateway for authorized AI workspaces, model accounts, search tools and local workers. ROTOXY combines Token2OAuth's OAuth/MCP gateway with Snooze's durable jobs and monitoring. Existing token2oauth commands, configuration paths and client URLs remain compatible.
Workspace providers: pooled LightSprint access, pinned sessions, distributed job tools and a persistent supervisor.
Models & APIs: an encrypted Ollama Cloud key pool, scoped model tokens, and explicitly permitted Exa, Firecrawl and Tavily search/extraction tools.
Private workers: a durable Oracle queue with health, assignments, model names and reported throughput.
Codex profiles: isolated official CLI sign-in, model discovery and reported AI quota windows. Automatic subscription pooling/dispatch is not enabled.
The dashboard distinguishes reported values, historical snapshots and unknown metrics. Monitoring survives a closed chat while the service host remains online. Automatic recovery capabilities and client limitations are described in the consolidation checkpoint and the actionable supervision update.

Quick install
Install Node.js 22+, Git, npm and an authenticated Tailscale client first, then run:
curl -fsSL https://raw.githubusercontent.com/p5n-n3t/token2oauth/main/install-rotoxy.sh | bash
rotoxy upThe manual installer prepares the gateway and foreground Funnel units without enabling boot startup or publishing routes. rotoxy up starts the configured services and publishes one root route to port 2030. rotoxy down withdraws that route and stops the services. Existing conflicting routes cause a refusal and must be migrated explicitly; global resets are never used. Oracle and monitoring units are started when separately installed and configured.

--upstream-url https://provider.example.com/mcpFirst run
1. Open the admin console
The installer prints the Gateway, MCP, and Admin URLs. On first initialization it also generates an admin password. Only its scrypt hash is persisted.
2. Configure the real upstream MCP URL
Use the web Admin console, or:
token2oauth config set upstreamUrl https://provider.example.com/mcp3. Add your authorized provider accounts
token2oauth account add --label "Pro account 1"
token2oauth account add --label "Pro account 2" --weight 1.5
token2oauth account add --label "Pro account 3" --priority 503a. Test every credential
New accounts begin as unknown until the proxy uses them. To verify every
token before attaching ChatGPT, run a direct authenticated MCP initialize
probe. It runs sequentially and records only the resulting status, never the
token itself:
token2oauth account probeThe admin console provides Test credential and Test all enabled credentials controls with the same behavior.
The interactive CLI disables terminal echo while the token is entered.
For automation:
printf '%s' "$PROVIDER_TOKEN" |
token2oauth account add --label "CI account" --token-stdin
token2oauth account add \
--label "Environment account" \
--token-env PROVIDER_TOKEN4. Add one URL to ChatGPT
Add only:
https://your-node.your-tailnet.ts.net/token2oauth/mcpToken2OAuth advertises OAuth metadata. ChatGPT performs OAuth with Token2OAuth; upstream bearer tokens stay on your host.
See ChatGPT OAuth.
Smart pooling
The default strategy is adaptive-sticky.
For a new MCP session, Token2OAuth favors an enabled credential with low normalized usage, low error rate, no cooldown, and low current concurrency. Once the upstream establishes an MCP session, Token2OAuth pins that session to the same upstream credential.
This distributes load without randomly switching accounts in the middle of a stateful MCP session.
Signal | Default action |
2xx | mark healthy and clear failure streak |
401 | mark credential auth-failed |
402 | mark exhausted and cool down |
429 | honor Retry-After, cool down, choose another |
quota/credit exhaustion text | cool down even if provider uses another status |
5xx, timeout, network failure | short cooldown and failover |
request already has Mcp-Session-Id | no cross-account failover by default |
There is intentionally no fake "remaining credits" counter. If a provider publishes a real usage endpoint, a provider adapter can add proactive checks. Otherwise provider responses are more reliable than guessing.
See Pooling and failover.

token2oauth pools previewFor the unified foreground stack use rotoxy up|down|status. The older lifecycle up|down and tailscale expose commands refuse changes when a foreground stack exists; otherwise they are dry runs that print the exact
commands unless --execute is given. They only ever add or remove the
/token2oauth mount, re-read tailscale serve status --json before and after
each write, and stop if any other route changed.
Admin console
Pool — upstream URL, strategy (with live help for each choice), failover/cooldown/timeout settings and per-credential health probes.
Tools — per-account tool inventory from
tools/list, enable/disable toggles enforced by the gateway for every MCP client, and "replay-safe" marks for read-only tools.Diagnostics — doctor report, read-only service/Funnel check, request analytics by account and tool, recent events in plain language, and quota data only when a provider actually reports it.
Security — regenerate the admin password (shown once) and optionally disconnect every MCP client.
Every admin form is CSRF-protected and the admin cookie is scoped to the gateway path.
Every command supports --help through Commander.
LightSprint
Token2OAuth is provider-agnostic. For LightSprint or another service, configure the actual remote MCP endpoint that accepts the account's bearer credential, then add each authorized account token to the pool.
Example labels:
LightSprint Pro #1
LightSprint Pro #2
LightSprint Pro #3
LightSprint Pro #4
LightSprint Pro #5The public LightSprint CLI/plugin demonstrates Bearer-token API calls, token refresh and explicit handling of HTTP 429. Token2OAuth therefore treats 429/Retry-After as a strong cooldown signal by default, while also supporting configurable credit/quota patterns. It does not assume an undocumented balance endpoint.
Tailscale
Token2OAuth never calls tailscale funnel reset or tailscale serve reset.
The generated route is equivalent to:
tailscale funnel --bg \
--https=443 \
--set-path=/token2oauth \
http://127.0.0.1:2030See Tailscale deployment.
Docker
Tailscale normally stays on the host:
docker compose up -d --build
tailscale funnel --bg --https=443 --set-path=/token2oauth http://127.0.0.1:2030Persist the data volume. It contains encrypted account envelopes, OAuth client state, and the local master key.
Security
Upstream tokens are encrypted with AES-256-GCM using a random 256-bit key stored separately in ~/.config/token2oauth/master.key. The admin UI never reveals a stored bearer token. Gateway OAuth access tokens are short-lived and audience-bound; refresh tokens are stored as hashes and rotated.
Read SECURITY.md before putting the gateway on a public hostname.
Development
git clone https://github.com/p5n-n3t/token2oauth.git
cd token2oauth
