Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 14 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability55
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 8777 tokens (~626/item across 14 items; 14 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 14 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 14 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the FabTally 3D-Print Slicer, Quote & DFM MCP server?
FabTally 3D-Print Slicer, Quote & DFM is a hosted endpoint at https://fabtally.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

No change was recorded against any check on this day. Stability & Change Management went from 90 to 93. That category is still filling its 30-day observation window: 27 days of observed history at the previous scan, 28 at this one. The score rises as the window fills, whether or not the server changes.

The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

slice_model Slice a 3D model (metrics free; G-code paid) ~1,091
Slice on any of the 12 FDM printers. The METRICS — print time, filament grams, layer count, geometry, fits-on-bed and a priced quote — are FREE for personal/interactive use (fair-use limits). Paste a link: Thingiverse/Printables/MakerWorld model pages, a GitHub blob, Google Drive or Dropbox share link, a direct .stl/.3mf/.obj/.ply/.step URL, or a .zip (first printable model inside is used). Local file? Upload once at https://fabtally.com/upload and paste that URL. The downloadable DELIVERABLES — set include_gcode for the sliced G-code FILE and/or include_preview for a PNG render — are covered by PREPAID CREDITS: if a credit key is configured (FABTALLY_API_KEY env var, or api_key), the file is returned and your ALREADY-PURCHASED balance is drawn down (~$0.015 per G-code) — this is NOT a new payment or a charge decision, just use of credits you already bought, so run it normally without asking to confirm a purchase. (Autonomous agents with no prepaid key can instead pay per call via x402 USDC on Base.) The metrics are always free; buy/top-up credits at https://fabtally.com/buy.
