check_fulu_orca_setup

Verify FULU OrcaSlicer-bambulab setup by inspecting installation, runtime payload, and commands; optionally probe BambuNetwork bridge to diagnose issues.

Instructions

Inspect a FULU OrcaSlicer-bambulab install, platform runtime payload, setup commands, and optionally probe the BambuNetwork bridge.

Tool call template

This tool declares no required parameters. Add optional parameters from the input schema as needed.

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "arguments": {},
    "name": "check_fulu_orca_setup"
  }
}

Input Schema

Name	Required	Description
`platform`	No	Platform to inspect. Defaults to the current Node.js platform.
`plugin_dir`	No	Directory containing the FULU Bambu runtime payload; on macOS this is usually OrcaSlicer.app/Contents/MacOS. When run_bridge_probe=true, requires MCP_ALLOW_EXECUTABLE_ARG=1 to be accepted here.
`runtime_dir`	No	Installed runtime directory. On macOS this defaults to ~/Library/Application Support/OrcaSlicer/macos-bridge/runtime. When run_bridge_probe=true, requires MCP_ALLOW_EXECUTABLE_ARG=1 to be accepted here.
`slicer_path`	No	Path to the FULU OrcaSlicer executable. Defaults from SLICER_PATH/FULU_ORCA_PATH. When run_bridge_probe=true, requires MCP_ALLOW_EXECUTABLE_ARG=1 to be accepted here.
`bridge_command`	No	Command that starts the FULU BambuNetwork bridge host for probing. Read from FULU_BAMBU_BRIDGE_COMMAND by default; requires MCP_ALLOW_EXECUTABLE_ARG=1 to be accepted here.
`probe_timeout_ms`	No	Bridge probe timeout in milliseconds (default: 5000).
`run_bridge_probe`	No	When true, sends bridge.handshake, bridge.capabilities, and bridge.runtime_info to the bridge host.

C2.9/5.0

Behavior2/5

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

No annotations are provided, so the description carries full behavioral burden, and it does not disclose that run_bridge_probe spawns a bridge host process, that bridge_command is an executable that will be launched, or that some inputs are gated behind MCP_ALLOW_EXECUTABLE_ARG=1 (that constraint appears only in the schema). It also says nothing about side effects or environment 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?

A single dense sentence that front-loads the inspection targets and appends the optional probe last. No filler, though the packing of five distinct concerns into one clause makes it slightly harder to scan.

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?

For a 7-parameter diagnostic tool with no annotations and no output schema, the description should convey what the inspection returns and what the optional probe yields, but it stops at naming the targets. An agent cannot predict the shape or content of the result, leaving a significant gap.

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?

Schema description coverage is 100%, so all seven parameters (including the enum platform and the executable-gated paths) are already fully documented in the schema, setting the baseline at 3. The description adds no parameter-level meaning beyond what the schema provides.

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?

States a clear verb (inspect) and specific resources (FULU OrcaSlicer-bambulab install, runtime payload, setup commands, BambuNetwork bridge), so an agent knows this is a diagnostic/inspection tool. It does not explicitly distinguish itself from the related sibling fulu_bambu_network_rpc, which is the only differentiation gap.

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?

The description gives no when-to-use or when-not-to-use guidance and names no alternatives. The only usage signal is the word 'optionally probe', which hints at a conditional mode but never says when an agent should enable it versus run a plain inspection.

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