Pure Data MCP Server

by nikmaniatis

clear_workspace

Clears all objects from the Pure Data workspace subpatch and resets object index tracking for starting fresh.

Instructions

Clear all objects from the Pd workspace subpatch and reset index tracking.

This sends /pd/clear to Pure Data, which clears the workspace subpatch,
and resets the server-side object index counter so new objects start from 0.

Args:
    ctx: MCP context

Returns:
    Response with status and number of objects cleared

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault

No arguments

Behavior3/5

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

No annotations are provided, so the description carries full burden. It discloses the action of clearing objects and resetting index tracking, but does not mention potential side effects like loss of unsaved work or prerequisites. Destructive nature is implied but not explicitly warned.

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 concise with a single main sentence and a note about the underlying command. It is front-loaded and includes Args/Returns sections without unnecessary detail.

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 zero parameters and no output schema, the description is fairly complete. It explains the action and return value, though it could mention prerequisites or safety considerations for a destructive operation.

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 no parameters, so schema coverage is 100%. The description does not need to add parameter info; baseline score of 4 is appropriate.

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 clears all objects from the Pd workspace subpatch and resets index tracking. It uses a specific verb 'clear' and resource 'workspace', distinguishing it from siblings like delete_object which target individual objects.

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 explicitly state when to use this tool versus alternatives. While it implies it is for a full workspace reset, no guidance is given on when not to use it or what tools to use for partial deletions.

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