Bitbucket Server MCP

list_branches

Retrieve a paginated list of branches from a Bitbucket repository, with optional text filtering for branch names.

Instructions

List branches in a repository (paginated).

Args: project_key: The project key. repo_slug: The repository slug. filter_text: Optional text to filter branch names. start: Page start index (default 0). limit: Number of results per page (default 25).

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

Behavior4/5

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

Since no annotations are provided, the description carries the full burden of behavioral disclosure. It explicitly mentions pagination and explains the start and limit parameters, which are key behavioral aspects. It does not mention any side effects, which is appropriate for a read operation.

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

Conciseness4/5

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

The description is reasonably concise with two sentences and a parameter list. It front-loads the purpose. The parameter list adds clarity but could be slightly more compact; overall it is well-structured.

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 the tool's complexity (5 simple parameters, no nested objects, output schema present), the description covers the purpose and parameters well. It does not discuss error conditions or prerequisites, but for a list operation this is acceptable. A mention of pagination details is already included.

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 schema description coverage is 0%, so the description must compensate. It provides explanations for all five parameters, including defaults for start and limit, and the role of filter_text. This adds meaningful semantics beyond the bare schema.

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 action (list) and resource (branches), and explicitly notes pagination. It distinguishes from siblings like create_branch (different action) and list_tags (different resource).

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 does not provide explicit guidance on when to use this tool versus alternatives such as list_commits or browse_files. Usage context is implied through the action and parameters, but no when-not or alternative recommendations are given.

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