postiz-mcp

postiz_connect_integration

Generate an OAuth authorization URL to connect a new social channel. Returns a browser URL that completes the authentication flow via Postiz's callback, without requiring a local server.

Instructions

Generate the OAuth authorization URL for connecting a new social channel. Returns a url the user must open in a browser to finish the flow — Postiz redirects back to its own callback. This tool does NOT run a callback server. Requires enableWrite.

A4/5.0

Behavior3/5

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

With no annotations provided, the description carries the full burden of disclosure. It explains that the tool returns a URL and does not run a callback server, but it does not disclose potential side effects, such as whether a pending integration is created, or what happens if the URL is used multiple times. This is adequate but not thorough.

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 description is extremely concise, consisting of two sentences that convey the core purpose, the return type, a key behavioral note, and a requirement. No extraneous information is included, and the most critical points are front-loaded.

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 tool with two simple parameters and no output schema, the description covers the essential aspects: what the tool does, what it returns, a notable limitation (no callback server), and a permission requirement. It lacks details on the expected response structure beyond the url, but this is minor given the tool's simplicity.

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

Parameters3/5

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

The input schema covers both parameters with descriptions, achieving 100% coverage. The description adds minimal extra value by mentioning the default for 'refresh' (false) and the meaning of 'provider' (slug). Since the schema already provides the parameter semantics, the description does not significantly enhance understanding.

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 clearly states the tool generates an OAuth authorization URL for connecting a new social channel, using the verb 'Generate' and resource 'OAuth authorization URL'. It distinguishes itself from sibling tools like 'postiz_check_integration' and 'postiz_list_integrations' by specifying its unique role in initiating the OAuth flow.

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 mentions that the tool requires enableWrite and that it does not run a callback server, providing implicit guidance on when to use it. However, it does not explicitly compare to alternative tools or state when not to use it, leaving some room for ambiguity.

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