Slack Notifications MCP Server

check_build_status

Retrieve recent Xcode Cloud build status from Slack notifications, including workflow name, duration, and timestamp. Filter by workflow for specific builds.

Instructions

Get the latest Xcode Cloud build status from Slack notifications. Returns recent build messages including status, workflow name, duration, and timestamp.

Tool call template

This tool declares no required parameters. Add optional parameters from the input schema as needed.

Input Schema

Name	Required	Description	Default
`limit`	No	Number of recent build messages to retrieve (default: 5, max: 20)
`workflow`	No	Filter by workflow name (e.g., 'Cuti-E-Admin', 'Nutri-E'). Case-insensitive partial match.

Behavior2/5

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

No annotations are provided, so the description carries full burden. It indicates a read-like operation ('get') but does not explicitly state it is safe or non-destructive. Missing details on permissions, rate limits, or side effects.

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 two sentences, front-loaded with the tool's purpose, and efficient with no waste. Every sentence adds value.

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?

Given 100% schema coverage and simple parameters, the description is fairly complete. It lists return fields (status, workflow, duration, timestamp) but could clarify ordering (e.g., 'latest' meaning most recent) or mention that it filters specifically for Xcode Cloud notifications.

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?

Schema description coverage is 100%, and parameters are well-described in the schema (limit with default/max, workflow with case-insensitive partial match). The description adds no additional meaning beyond the schema, so baseline 3.

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 gets the latest Xcode Cloud build status from Slack notifications and specifies the return fields (status, workflow name, duration, timestamp). It distinguishes from sibling tools like get_channel_messages or search_messages, which are general Slack operations.

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

Usage Guidelines3/5

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

The description implies usage for retrieving Xcode Cloud build notifications but does not explicitly state when to use it versus alternatives or provide exclusions (e.g., not for general messages). No guidance on prerequisites or when not to use.

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