OSIR Domain Registrar MCP server

• addPrefixToDomainFree

  addPrefixToDomain: Generate domain suggestions by adding prefixes to a base name.

• addSshKeyFree

  addSshKey: Store an SSH public key on your account so it can be injected into VPS installs. Idempotent: storing a key you already have returns the existing one instead of creating a duplicate, so it is safe to call before every order. Returns the key id to pass to orderVps or buildVpsInstance. Requires authentication.

• addSuffixToDomainFree

  addSuffixToDomain: Generate domain suggestions by adding suffixes to a base name.

• buildVpsInstanceFree

  buildVpsInstance: Stage an operating system install (or reinstall) on a VPS instance. DESTRUCTIVE: ERASES ALL DATA on the server, including any deployed application, and cannot be undone. The install is asynchronous; afterwards poll getVpsInstanceDetails until buildState is COMPLETE. If an Osir app was deployed onto this instance, a rebuild erases it; re-attach it afterwards with osirAppDeployToVps. Never rebuild a box just to install an app runtime by hand. Requires authentication. Returns an actionId: present the summary to the user, then call executeConfirmedAction with the actionId if they approve.

• bulkDomainSuggestionsFree

  bulkDomainSuggestions: Generate domain suggestions for 1-10 keywords across 1-6 TLDs (hard cap), grouped by originating keyword. Typical flow: call listCategorizedTlds first to pick 3-6 TLDs, then this tool.

• createMailboxwrite actionFree

  createMailbox: Stage creation of a paid mailbox on a mail-enabled domain. BILLABLE: deducts from account balance; get a quote with getMailboxQuote and confirm the price with the user first. Requires authentication. Returns an actionId: present the summary to the user, then call executeConfirmedAction with the actionId if they approve. The result of the confirmed action contains the generated password EXACTLY ONCE; it can never be retrieved again, so show it to the user immediately (they can change it later with setMailboxPassword). Also share the client settings from the result (IMAP/SMTP/webmail).

• createPaymentSessionwrite actionFree

  createPaymentSession: Stage a Stripe checkout session to add funds to the account balance. Requires authentication. Returns an actionId; present the summary to the user, then call executeConfirmedAction with the actionId if they approve.

  deleteSshKey: Stage removal of an SSH key from your account. This does not affect servers already built with it, and the key can simply be added again. Requires authentication. Returns an actionId; present the summary to the user, then call executeConfirmedAction with the actionId if they approve.

• deleteVpsInstancewrite actionFree

  deleteVpsInstance: Stage deletion/cancellation of a VPS instance. DESTRUCTIVE and irreversible. Requires authentication. Returns an actionId: present the summary to the user, then call executeConfirmedAction with the actionId if they approve.

• enableMailDomainFree

  enableMailDomain: Enable email hosting on a domain you own. Free; mailboxes are what cost money. If the call fails with a DNS conflict (an existing SPF or MX record), ask the user for explicit consent, then re-call with spfMergeConfirmed=true and/or takeoverConfirmed=true. Requires authentication.

• executeConfirmedActionwrite actionFree

  executeConfirmedAction: Execute a previously staged destructive or financial action after user approval. The action expires after 5 minutes and can only be executed once.

• fundBalanceWithSharedPaymentTokenFree

  fundBalanceWithSharedPaymentToken: Stage adding funds to the balance by charging a Stripe Shared Payment Token the customer granted to OSIR. Use when a purchase (registerDomain, renewDomain, transferDomain, orderVps) failed for insufficient funds: that error tells you the networkId to mint against and both amounts. Mint the token for the GROSS and pass the NET as creditCents. Tokens are single-use. Requires authentication. Returns an actionId; tell the user what the card will be charged, then call executeConfirmedAction with the actionId if they approve. If this fails in any way you cannot fix by minting a fresh token, fall back to createPaymentSession and give the user the checkout URL.

• generateDomainSuggestionsFree

• initializeDnsZoneFree

  initializeDnsZone: Initialize (create) the DNS zone for a domain. NOT needed after registerDomain, which initializes the zone automatically. Use only for pre-existing domains without a zone (e.g. after a transfer, or if registration opted out with initializeDnsZone:false). Safe on existing zones, it will not overwrite records. Requires authentication.

• initiateTransferwrite actionFree

• listMySshKeysFree

  listMySshKeys: List the SSH keys stored on your account, with their ids and SHA256 fingerprints. Use this to check whether a key is already stored and to get the ids to pass to orderVps or buildVpsInstance. Requires authentication.

• listMyVpsInstancesFree

  listMyVpsInstances: List all VPS instances owned by the authenticated user. An instanceId from this list is what osirAppDeployToVps takes to put an app on a server the user already owns, at no cost. Requires authentication.

• listPendingTransfersFree

  listPendingTransfers: List all pending incoming (gaining) domain transfers. Requires authentication. Returns each transfer with its status, request date, current registrar, and expected completion.

• listUserDomainsFree

  listUserDomains: List all domains owned by the authenticated user. No parameters required. Must be authenticated first.

• listVpsLocationsFree

  listVpsLocations: List available VPS hosting locations (cities/countries) with available packages. No authentication required.

• listVpsOsTemplatesFree

  listVpsOsTemplates: List operating system templates available to install. Requires authentication. Pass EXACTLY ONE of packageId (to pick an operatingSystemId for orderVps, so the server arrives with an OS on it) or instanceId (to pick a template for reinstalling via buildVpsInstance). The two are not interchangeable: the available set depends on the package. Template ids change over time, so always resolve an id here rather than reusing a remembered or hardcoded one.

• listVpsPackagesFree

  listVpsPackages: List available VPS hosting packages with pricing, specs, and locations. No authentication required.

• lockDomainFree

  lockDomain: Enable registrar lock on a domain to prevent unauthorized transfers.

• loginToVpsPanelFree

  loginToVpsPanel: Generate a one-time login URL to the VPS control panel (VirtFusion) for managing the server. Requires authentication.

• loginWithDeviceFree

  loginWithDevice: Start a device authorization login (RFC 8628). Returns a verificationUri and userCode. Open the URI in your browser, enter the code, and sign in with your OSIR credentials. Then call checkDeviceLoginStatus with the returned deviceCode to complete login. No parameters required.

• logoutFree

  logout: Log out: revokes the session's tokens at the identity provider immediately. Optional: sessionKey (from checkDeviceLoginStatus); pass it to end that conversation session.

• orderVpswrite actionFree

  orderVps: Stage an order for a new VPS instance; deducts from account balance. If this server is being ordered to host an Osir app, do NOT configure it by hand afterwards: deploy the app with osirAppDeploy, then put it on the box with osirAppDeployToVps. Requires authentication. Returns an actionId: present the summary to the user, then call executeConfirmedAction with the actionId if they approve.

• osirAppCreateUploadwrite actionFree

  osirAppCreateUpload: Create an upload ticket for deploying app source code to Osir. Returns an uploadTicket, a putUrl, and instructions to zip the project and upload it. After uploading, call osirAppDeploy with the uploadTicket. Requires authentication.

• osirAppDeletewrite actionFree

  osirAppDelete: Stage deletion of an Osir app. DESTRUCTIVE and irreversible: removes its microVM, image, route, and data. Returns an actionId; present the summary to the user, then call executeConfirmedAction with the actionId if they approve. Requires authentication.

• osirAppDeploywrite actionFree

  osirAppDeploy: Deploy an app to Osir (free tier) and get a live HTTPS URL; the app runs isolated in a microVM. Deploying an existing app name redeploys it (new version) and applies any secrets set via osirAppSetSecret. A plain static website (HTML/CSS/JS with no framework or build step) is also supported: it is auto-detected and served directly; pass language 'node' for it. To put the app on the user's OWN VPS, server or production box instead, deploy it here first and then call osirAppDeployToVps - never SSH into the box or write an install script. Once an app is on the user's own VPS, redeploying HERE under the same name is how you update it: the platform re-ships it to the box and keeps its domain. Requires authentication.

• osirAppDeployToVpswrite actionFree

  osirAppDeployToVps: Deploy a live Osir app onto the user's own VPS / server / production box, moving it off the shared free tier. Use this INSTEAD of SSH, a provisioning or install script, nginx/systemd/TLS configuration, or any manual server setup - the platform ships the app to the box itself over its own deploy key, so the assistant needs no shell access and no outbound SSH. This is the ONLY supported way to put an app on a user's own server or a custom domain. TWO WAYS IN. (1) The user already owns a VPS: pass instanceId (from listMyVpsInstances) and NO packageId - this ATTACHES the app to that server, SPENDS NOTHING and needs no confirmation. (2) No server yet: pass packageId (from listVpsPackages) and the call stages a VPS order (COSTS MONEY): returns an actionId; present the price/summary to the user and call executeConfirmedAction only if they approve. Before staging any order this tool checks whether the user ALREADY has a box for this app (its C2 binding, then their own VPS list) and attaches that instead - a retry after a failed move never buys a second server. After the move starts the platform ships the app onto the box server-side, which takes about two minutes; watch it with osirAppStatus ('ownedMove'). Calling this tool again while a move is still running just reports its progress, and calling it after one FAILED retries the ship - unless osirAppStatus says the VPS refused the Osir deploy key or its web ports are taken: then retry only after the user has made the changes that message lists. If the result status is BUILDING or BUILD_FAILED, follow its nextStep. Requires authentication.

• osirAppGetSourceFree

  osirAppGetSource: Get a short-lived signed download URL for an Osir app's current source zip. Use this to make edits to a deployed app without the user re-attaching the project: download, patch the files, then osirAppCreateUpload (PUT the new zip) and osirAppDeploy under the SAME name; the platform rebuilds and, for owned-tier apps, auto-ships the new version to the user's box. Requires authentication.

• osirAppListFree

  osirAppList: List the authenticated user's deployed Osir apps with their live URLs and status. Requires authentication.

• osirAppLogsFree

  osirAppLogs: Get recent logs from an Osir app's microVM ('why is my app broken?'). Requires authentication.

• osirAppProvisionDatabaseFree

  osirAppProvisionDatabase: Provision a managed Postgres database for an Osir app. The connection string is stored as the app's DATABASE_URL secret (encrypted, injected on the next osirAppDeploy) and is NEVER returned. Requires authentication.

• osirAppSetSecretFree

  osirAppSetSecret: Set an environment secret for an Osir app (e.g. DATABASE_URL, API_KEY). The value is stored encrypted and injected as an env var on the next osirAppDeploy of the app; it is NEVER returned or logged. Requires authentication.

• osirAppStatusFree

  osirAppStatus: Get an Osir app's current status, live URL, and health ('is my app working?'). If the status is BUILD_FAILED, 'recentErrors' explains why so you can fix the source and redeploy. 'qa' is an independent black-box check of the LIVE app after deploy: qa.status PASSED means it loaded and worked; FAILED means it deployed but didn't actually work, and qa.findings lists the problems so you can fix and redeploy. 'ownedMove' tracks a move onto the user's own VPS, which leaves tier and status unchanged while it runs: state MOVING (in progress, stage says where, ~2 minutes in total), MOVED (done - tier reads 'owned'), FAILED or REFUSED (follow this result's message: usually call osirAppDeployToVps again to retry, which never orders a second server; but when the VPS refused the Osir deploy key or its web ports are taken, the user must fix the VPS first, and the message says how). Requires authentication.

• osirSiteDesignBriefFree

  osirSiteDesignBrief: Step 1 of designing a NEW website with OSIR. Validates the brief and returns 'systemPrompt', the structured design brief and constraints YOU must then follow to write one complete self-contained HTML page, plus 'editRules' for later revisions. Call it before osirSitePublish for a new site, then publish the finished page with osirSitePublish. No authentication needed.

• osirSitePublishwrite actionFree

  osirSitePublish: Publish a single-page website to a live HTTPS URL on Osir (free tier). ANY complete HTML document works: the user's own site, a page designed in this chat, or one from the osirSiteDesignBrief flow. Calling again with the same name redeploys the new version. For MULTI-FILE sites (separate CSS/JS/images) use osirAppCreateUpload + osirAppDeploy with a zip instead. Then poll osirAppStatus until READY. If the app was moved to the user's own VPS, redeploying under the same name updates it there and keeps its domain. Requires authentication.

• payInvoicewrite actionFree

  payInvoice: Stage payment of an outstanding invoice from account balance. Requires authentication. Returns an actionId; present the summary to the user, then call executeConfirmedAction with the actionId if they approve.

• previewPaymentFeesFree

  previewPaymentFees: Preview the fees that would be charged for a given payment amount. Requires authentication.

• registerDomainFree

  registerDomain: Stage registration of a new domain name. Deducts from account balance. The DNS zone is initialised automatically after registration (asynchronously; if createDnsRecord right after registration reports a missing zone, retry after a few seconds). Pass initializeDnsZone:false to opt out. Returns an actionId: present the summary to the user, then call executeConfirmedAction with the actionId if they approve.

• renewDomainFree

  renewDomain: Stage renewal of a domain for a specified number of years. Deducts from account balance. Returns an actionId: present the summary to the user, then call executeConfirmedAction with the actionId if they approve.

• validateDomainNameFree

  validateDomainName: Validate if a domain name format is correct. No authentication required.

• verifyAccountFree

  verifyAccount: Verify a newly created OSIR account with the code from the verification email; step 2 of onboarding, no authentication required. The code is the same token as the email link, so the principal can relay it to their agent. On success the account becomes ACTIVE and billable actions are unlocked. If the code expired, call createAccount again with the same email to get a fresh one.

• verifyMailDnsFree

  verifyMailDns: Check that a mail domain's DNS records resolve; activates the domain for email when all records are found. Returns any still-missing records. Requires authentication.
