orcaslicer-mcp@0.1.25

CAUTION· not started

Publisher claims: "Work a running OrcaSlicer from Claude or any MCP client: load models, tune settings, slice, and understand the result through per-feature breakdowns, setting explanations, and physics checks" Observed in sandbox: no network, touches nothing outside the project, writes no memory.

Coverage

Not started: dependency install failed; the server itself was not observed.
Tested
the dependency install step · every file read, file written and host contacted by what ran
Not tested
server startup · the tool list · tool behavior

What this means for the label: Caution here covers what ran. The server's tools were not exercised with a real credential, so nothing about their behavior is asserted; the credential summary below says what to do with that.

Before you give it your token

It will ask for
ORCA_PRINTER_API_KEYORCA_TOKENUV_PUBLISH_TOKENConfiguration, not credentials: ORCA_API_TIMEOUT, ORCA_BASE, ORCA_MCP_ALLOW_KEYS, ORCA_MCP_NOTES_DIR, ORCA_PRINTER_ID, ORCA_PRINTER_URL, PRINT_OUTCOMES_DIR
Where it talks to
orcaslicer.com (its own)
What the honeypot saw
no credential files read · no network
What we could not test
server startup · the tool list · tool behavior

Connect it with a scoped credential, under the guard. It asks for ORCA_PRINTER_API_KEY, ORCA_TOKEN, UV_PUBLISH_TOKEN and talks to orcaslicer.com. Give the credential to the guard, not the server: the value never enters the server's environment and only travels to the host you bind. What the tools do with a real credential was not observed.

$vet-skills run --secrets ORCA_PRINTER_API_KEY=orcaslicer.com,ORCA_TOKEN=orcaslicer.com,UV_PUBLISH_TOKEN=orcaslicer.com -- uvx orcaslicer-mcp

Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios; not started: dependency install failed; the server itself was not observed) on 2026-11-13 and scored it 73/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: URL with embedded credentials; Destructive file system command detected; HTTP URL with a raw public IP address. Summary: no network, touches nothing outside the project, writes no memory.
