blender_mcp_edit_model

Send STL edit instructions to a Blender MCP bridge to apply remesh, boolean, or decimate operations for advanced model editing before 3D printing.

Instructions

Send STL-edit instructions to a Blender MCP bridge command for advanced model edits

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
stl_pathYesPath to the local STL file
operationsYesOrdered edit operations for Blender (e.g. remesh, boolean, decimate)
bridge_commandNoOverride command for invoking Blender MCP bridge
executeNoExecute bridge command (true) or return payload only (false)
Behavior2/5

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

No annotations provided. The description only says 'send instructions' without disclosing side effects, environment requirements, or execution behavior. Lacks transparency.

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?

Single sentence is concise and contains essential information. No wasted words, but could be slightly more informative.

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

Completeness2/5

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

Missing output schema and annotations. Description does not explain return values, error conditions, or format of operations array. Insufficient for a 4-parameter tool.

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?

Input schema has 100% coverage with clear descriptions for all 4 parameters. The description does not add extra meaning beyond the schema, but baseline 3 is acceptable.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool sends STL-edit instructions to a Blender MCP bridge for advanced edits. While it distinguishes from basic edit tools like rotate_stl, it doesn't fully differentiate from other bridge tools.

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

Usage Guidelines2/5

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

No guidance on when to use this tool vs alternatives like center_model or lay_flat. No prerequisites or exclusions mentioned.

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