OrcaSlicer MCP Server
Server Configuration
Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|
| workdir | No | The directory that will serve as the working folder for projects and operations. |
Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| list_profilesC | List available profile files for a given category (machine, filament, or process). |
| search_settingsA | Search for setting keys containing a keyword across all (or a specific type of) profiles. Useful when you don't know the exact key name — e.g. query "infill" returns all infill-related settings and their current values. |
| get_profile_contentB | Read and return the full JSON content of a profile file. |
| update_profile_settingA | Update a single setting key in a profile. By default (dry_run=true), the change is saved to a _tuned copy rather than overwriting the original. |
| slice_modelC | Run OrcaSlicer CLI to slice a model file. Specify input/output filenames and optionally profiles to use. |
| analyze_gcode_metadataB | Parse metadata (estimated time, filament usage, cost, layers) from a G-code file and return structured JSON. |
| health_checkB | Diagnose the server environment: check if the OrcaSlicer binary is reachable and if the settings/work directories are accessible. |

Scored across 7 tools
Each tool has a clearly distinct purpose with no overlap: analyze_gcode_metadata parses G-code files, get_profile_content reads profiles, health_check diagnoses the server, list_profiles enumerates profiles, search_settings finds settings, slice_model performs slicing, and update_profile_setting modifies profiles. The descriptions clearly differentiate their functions, making misselection unlikely.
All tool names follow a consistent verb_noun pattern using snake_case (e.g., analyze_gcode_metadata, get_profile_content, slice_model). The verbs are descriptive and appropriate for each action, and there are no deviations in naming conventions across the set.
With 7 tools, the count is well-scoped for an OrcaSlicer server, covering essential operations like slicing, profile management, and diagnostics. Each tool serves a clear purpose without redundancy, and the number is manageable for agents to navigate effectively.
The tool set provides strong coverage for core 3D printing workflows, including slicing, profile handling, and G-code analysis. A minor gap is the lack of tools for creating or deleting profiles, which might require workarounds, but the existing tools support most common tasks without dead ends.
