Pcloud Auth Start

pcloud_auth_start

Start pCloud OAuth authorization by generating a browser URL for user approval. After approval, the token is stored automatically, ready to confirm via status check.

Instructions

Begin browser authorization and return the URL for the user to approve.

Open the returned URL. The user approves there, pCloud redirects back to this server, and the token is stored automatically -- nothing is copied back by hand. Then call pcloud_auth_status to confirm.

A4.4/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations available, the description carries the full burden of behavioral disclosure. It explains that authorization happens in the browser, the redirect returns to this server, the token is stored automatically, and no manual copy/paste is required. It does not cover edge cases like repeated starts or token overwrites, but for a zero-parameter start action it is transparent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The primary purpose is front-loaded in the first sentence, followed by compact operational detail. Every sentence earns its place and the overall description is short, scannable, and free of redundant words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a zero-parameter tool with an output schema, the description covers the complete core workflow: initiate authorization, open URL, user approval, server redirect, automatic token storage, and confirmation via pcloud_auth_status. Minor omissions such as repeated-call behavior or edge cases do not materially affect an agent's ability to use the tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has zero parameters, so the baseline is 4. The description appropriately adds no parameter-specific information because there are no parameters to document.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific action ('Begin browser authorization') and the expected deliverable (a URL for the user to approve). It also refers to the follow-up sibling pcloud_auth_status, helping an agent distinguish this tool as the entry point from the other auth-related tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives a clear step-by-step usage flow: open the returned URL, user approves, the server receives the redirect, the token is stored automatically, then call pcloud_auth_status to confirm. It does not explicitly list when not to use alternative auth tools, but the sequencing is clear enough for an agent to know this starts the process.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
