List all pending incoming (gaining) domain transfers. Requires authentication. Returns a list of transfers with their status, request date, current registrar, and expected completion.
| Name | Required | Description | Default |
|---|---|---|---|
| sessionKey | No | Session key (osk_...) returned by checkDeviceLoginStatus. Pass it on every call when logged in via the in-chat device flow; omit when connected via OAuth. |
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden and does disclose an important behavioral trait: authentication is required. It also lists the output fields. However, it does not mention that the operation is read-only, how errors behave, or whether the list is paginated.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise, front-loaded with the core action and scope, and each sentence adds distinct value: what it lists, the auth requirement, and what the response contains. There is no filler.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a simple list operation with no output schema, the description provides the essential return fields and auth context. It falls slightly short on behavioral detail and does not clarify when to prefer this over related transfer-status tools.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already fully documents the single optional sessionKey parameter. The description adds no parameter-specific meaning, keeping this at the baseline of 3.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description uses a specific verb ('List') and a well-defined resource ('pending incoming (gaining) domain transfers'). It clarifies scope by saying 'pending' and 'incoming (gaining)', which distinguishes it from outgoing transfers and related transfer tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies when to use the tool by focusing on pending incoming transfers, but it does not explicitly contrast it with sibling tools like getTransferStatus or initiateTransfer. No exclusions or alternative routing guidance is provided.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
The set has several near-duplicate or heavily overlapping tools: initiateTransfer and transferDomain appear to do the same thing, and generateDomainSuggestions, bulkDomainSuggestions, suggestAlternatives, spinDomainWords, and addPrefix/addSuffixToDomain all occupy suggestion space. Account/profile tools like getAccountSummary, getMyProfile, getRecentActivity, and getMyAuditLogs also blur together.
Many tools follow verb_noun camelCase (createDnsRecord, listInvoices, updateContact), but the broader set mixes styles: osirAppCreateUpload vs osirAppList vs osirAppStatus, plus inconsistent verbs like check/verify/validate/preview for similar lookup actions. The naming is readable but not predictable across the full surface.
105 tools is an extreme count for any single MCP server, even one spanning domain registration, DNS, VPS, email, billing, app deployment, and site publishing. The surface would be far more coherent split into focused servers by domain.
Core domain, DNS, billing, VPS, mail, and app deployment workflows are broadly covered. However, there are notable gaps: no way to update or reassign the contacts on an existing domain, no update operation for host/glue records, and no VPS power operations like reboot or stop outside the external control panel.
