Pure Data MCP Server

by nikmaniatis

disconnect_objects

Remove a connection between two Pure Data objects by providing their source and destination IDs.

Instructions

Remove an existing connection between two Pd objects.

This tool disconnects two objects in the Pure Data patch.
It handles the translation from string IDs to numeric indices
required by the Pure Data patch.

Args:
    source_id: ID of the source object
    destination_id: ID of the destination object
    ctx: MCP context
    
Returns:
    Response with status

Behavior2/5

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

No annotations are provided, so the description bears full responsibility. It mentions handling string-to-numeric index translation but omits other behavioral traits such as error handling, side effects, or permission requirements.

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 concise with four sentences covering purpose, behavior, and parameters. It is well-structured and front-loaded, avoiding unnecessary details.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the simple tool with two string parameters and no output schema, the description explains the core functionality and the notable translation detail. However, it lacks information about failure cases, return value details beyond 'status', and the overall workflow context.

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

Parameters2/5

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

The input schema has zero description coverage, so the description must compensate. It labels parameters as 'ID of the source object' and 'ID of the destination object', which adds minimal meaning beyond their names. No further details on ID format or constraints.

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 verb 'remove' and the resource 'existing connection between two Pd objects'. It distinguishes from the sibling 'connect_objects' which performs the opposite action.

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. It implies usage for disconnecting objects, but lacks guidance on prerequisites or when not to use it.

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