Available Tools

The full list of 20 tools your coding agent can use through the Hamster MCP server.

Overview

When your agent connects to the Hamster MCP server, it gains access to 20 tools organized across six areas: accounts, briefs, tasks, subtasks, documents, and plans. These tools let the agent read your project context, create and update work items, and navigate between accounts — all scoped to your permissions.

Accounts

Tool	What it does
`list_accounts`	Show all your accounts (personal and team)
`switch_account`	Switch to a different account

Briefs

Tool	What it does
`list_briefs`	List briefs in the current account
`get_brief`	Get a brief's full content and metadata
`create_brief`	Create a new brief
`update_brief`	Update a brief's title, description, or status
`delete_brief`	Delete a brief

Tasks

Tool	What it does
`list_tasks`	List tasks for a brief, with optional filters for status, priority, and assignee
`get_task`	Get a task's full details including subtasks and dependencies
`create_task`	Create a new task under a brief
`update_task`	Update a task's title, description, priority, assignee, or other fields
`update_task_status`	Move a task to a new status (to do, in progress, done)
`get_next_task`	Get the next task to work on based on priority and dependencies

Subtasks

Tool	What it does
`list_subtasks`	List subtasks for a task
`create_subtask`	Add a subtask to a task
`update_subtask`	Update a subtask's content or status
`delete_subtask`	Remove a subtask

Documents

Tool	What it does
`list_documents`	List documents attached to a brief
`get_document`	Get a document's full content

Plans

Tool	What it does
`get_plan`	Get the full plan for a brief, including all generated tasks

Tips

get_next_task is particularly useful for agentic workflows. It returns the highest-priority task that has no unfinished dependencies — so the agent always picks up the right thing next.
get_task accepts both UUIDs and display IDs (like HAM-123), so your agent can reference tasks the same way you do.
list_tasks supports filters for status, priority, and assignee — useful when you want the agent to focus on a specific slice of work.
update_task_status handles reordering automatically. When the agent moves a task to "done", the task list stays correctly sorted.
