Preview what would happen if change_plan were called with this plan: the immediate-charge amount (cents), the next-invoice amount, the effective date, and the kind (`applied` for in-cycle upgrade, `scheduled` for at-period-end downgrade / cancel). Owner-only; requires a token minted with the billing scope.

Turn on archive protection for a project you own: archive_project (on every surface — panel, REST, and this tool) then refuses until it is lifted. Idempotent. Permanent from here — there is no tool or API call to turn it back off; only contacting support can. Requires an ACCOUNT-scoped token and the `config` scope.

Publish one line draft now and clear only its schedule.

Remove a member (accepted or pending) from this project by their member ID or email. Owner only.

Rename a project you own (the display name only — the slug, which is the identity in URLs / Redis, never changes). Requires an ACCOUNT-scoped token and the `config` scope. 404-equivalent error when you do not own the slug.

Re-send the invitation email for a still-pending invite, by member ID or email (from list_members). The original accept link is reused. Already-accepted members are rejected. Owner only.

Resume (un-cancel) a pending-cancel add-on whose paid-through cycle has not yet ended. Clears the cancellation so the add-on renews normally at the next cycle boundary. No new charge — the cycle was already paid. Stackable add-ons cannot be resumed; buy a new unit instead. Returns {addonKey, project, nextRenewalAt, resumed}. Owner-only; requires a token minted with the billing scope.

Re-enqueue a DLQ entry to the main relay stream and delete it from the DLQ. A replay is billed like any relay — it charges the entry's original credit cost to the project before re-sending; if the balance is too low the entry stays in the DLQ and this returns an insufficient-credits error (top up and retry). Succeeds if the entry exists, errors if it's already gone (retried or discarded). Requires edit access.

One-shot retrieval of the plaintext for a successor minted by the auto-rotation scheduler (not by rotate_api_key — that returns its own plaintext directly). Decrypts the at-rest ciphertext, returns it once, then destroys it; a second call errors. Only available while the predecessor still has an unrevealed successor.

Manual hard revoke. The key stops authenticating on the next request. Owner anywhere, editor on own keys.

Revoke a PROJECT-scoped API token on a project you own — any holder's, not just your own (the account-owner kill switch for a leaked or retired integration token). Soft-revoke: the row stays for traceability and the token is rejected immediately. Idempotent. Requires an ACCOUNT-scoped token and the `config` scope.

Publish a retained line revision immediately and clear any pending schedule.

Mint a linked successor for an existing key. Returns the successor plaintext exactly once — store it now. The predecessor stays valid through its overlap window so callers can swap without downtime. Owner anywhere, editor on own keys.

Schedule one non-empty line draft. Active subscribers required.

Enable or disable the auto-decaying burst window for live traffic and publish the change immediately. When enabled, brief spikes a little above your steady RPM cap are absorbed at the normal credit rate (no surcharge, no burst SKU) instead of being rejected. Sustained overage decays back to your steady cap; headroom returns once traffic cools below the cap or you add RPM. Burst usage is tracked so you can see when to upgrade. Default is off (steady cap is a hard 429). Requires edit access.

Turn the line's public OpenAPI docs on or off. When enabled, the line's spec is published at docs.{baseDomain}/{slug}/{lineKey} (and …/openapi.json); when disabled those URLs return 404. The `docsShared` field on each line read (list_lines) reflects the current state. Requires edit access.

Owner-only. Edit the project's key policy. Only fields present in the patch are touched. Editors calling this get an error — use get_key_policy to read.

Change a member's role between editor, viewer, and billing. Identify the member by their member ID or email (from list_members); the project owner's own role cannot be changed. Returns the updated member record. Owner only.

Narrow the project's outbound host allowlist — the hosts a target may point at. The current list is on get_project as `outboundHostAllowlist` (empty means any public host). This tool may only narrow it: `patterns` must be a strict subset of, or equal to, the current list, compared as exact strings — submitting a wildcard that would cover an existing exact host, or clearing to empty, is refused as a widen. Widening the list is web-only, in the panel. Refused when the project already has a target (inactive lines included) outside the submitted list. Requires edit access.

Set or clear a self-set ceiling on this project's own effective live-traffic RPM (Traffic shaping) — for when your origin can't take the throughput your plan grants. Never plan-gated: the ceiling can only LOWER your effective RPM below your plan/add-on rate, never raise it, and never touches billing. Steady traffic is capped at the ceiling; if Burst Protect is on, its headroom is measured above the ceiling, not above the plan rate. The current value is on get_project as `rpmCeiling` (null = no ceiling). Requires edit access.

Begin a new Pro or Scale subscription for the project owner. Returns `{checkoutUrl, plan}` — surface the URL to the human for approval. Errors if the owner is already on an active paid plan (use change_plan instead). Owner-only; requires a token minted with the billing scope.

Begin a credit-pack top-up for the project owner. Pass the pack`s `eurCents` (from list_credit_packs). Returns `{checkoutUrl, credits, eurCents, directCharge}` or `{transactionId, credits, eurCents, directCharge:true}` on subsequent MCP purchases. Owner-only; requires a token minted with the billing scope.

Subscribe the project owner to a monthly add-on (RPM upgrade, team seat, extended log retention, extra file storage in +5 GB blocks, …). Charges the saved payment method immediately, then auto-renews every 30 days until `unsubscribe_addon` — or until the subscription ends, after which the already-paid cycle stays active to its own end date and stops without further charges. Requires an active Pro/Scale subscription and a saved PM. RPM upgrades (rpm_*) are per-project and apply to THIS project automatically. Returns `{addonKey, project, monthlyEurCents, transactionId, activatedAt, nextRenewalAt}`. Owner-only; requires a token minted with the billing scope.

Restore an archived project you own to the data plane. Restoring consumes one of your plan's active-project slots, so at the limit this returns an error telling you to archive another project or upgrade. Idempotent for an already-active project. Requires an ACCOUNT-scoped token and the `config` scope.

Cancel an active add-on subscription. Stops future charges; the current cycle stays active until expiry. RPM upgrades are cancelled for THIS project. Returns `{addonKey, project, cancelledAt}`. Owner-only; requires a token minted with the billing scope.

Rename a credential and/or rotate its secret, publishing the change immediately so every target that uses this credential picks it up right away. Omit a secret field (or the whole `auth` object) to keep the existing value — the vault can never show a secret back to confirm it, so leaving it out means "unchanged," not "cleared." The destination host cannot be changed here: create a new credential for a new destination.

Update an endpoint immediately or in its line draft. The patch is merged field-by-field. Requires edit access.
