Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog) Scored 2026-08-03. - **Endpoint Security**: 57/100 - The endpoint's TLS certificate is valid, in date, and uses a strong key. - 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. - HTTPS is enforced; there's no plaintext access path. - HSTS check failed: the Strict-Transport-Security header is absent. - DNSSEC check failed: this domain isn't protected by DNSSEC. - **Transport & Reachability**: 100/100 - Verified streamable-http transport via a live MCP handshake. - **Schema Quality & AI Usability**: 40/100 - AI-judged instruction clarity (good). - 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. - Usage-examples check failed: none of the tools include examples. - **Stability & Change Management**: 10/100 - Stability observed for 3 of 30 days with no destabilising changes; credit accrues until the full window elapses. - **Tool Coverage**: 100/100 - 100% of tools have a non-trivial description (not blank, and not just the tool's name). - 100% of tool parameters carry a description. - **Capabilities**: 100/100 - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28. ## Install ### Claude ```bash claude mcp add --transport http com-fabtally-slicer https://fabtally.com/mcp ``` ### Codex ```toml [mcp_servers.com-fabtally-slicer] url = "https://fabtally.com/mcp" ``` ### opencode ```json { "$schema": "https://opencode.ai/config.json", "mcp": { "com-fabtally-slicer": { "type": "remote", "url": "https://fabtally.com/mcp", "enabled": true } } } ``` ### OpenClaw ```bash openclaw mcp add com-fabtally-slicer --url https://fabtally.com/mcp --transport streamable-http ``` ### Hermes ```yaml mcp_servers: com-fabtally-slicer: url: "https://fabtally.com/mcp" ``` ### Other ```json { "mcpServers": { "com-fabtally-slicer": { "type": "http", "url": "https://fabtally.com/mcp" } } } ``` The mcpServers block is a cross-client convention.

Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims. ### 2026-08-02 (score 57, +1) No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes. ### 2026-08-01 (score 56, −2) - [security] Tool “analyze_model” rewrote its description, which is the text the model reads - [security] Tool “check_printability” rewrote its description, which is the text the model reads -

Discovery: the live 12-printer FDM fleet (id, name, bed/build volume mm, nozzle), the 12 filament materials (PLA, PETG, ABS, ASA, Nylon, PC, TPU + carbon-fiber variants), and the pricing model. Call this FIRST to pick a `printer` and `material` id. Personal & interactive use is FREE (fair-use limits); per-call x402 / prepaid credits apply to agents, production and high volume. ### `check_printability` (~679 tokens) Check 3D-print printability (DFM) FREE 3D-printing DFM / printability check for an STL/3MF/OBJ/PLY model. 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. Default (full=false): a fast geometry-only read — printable verdict (yes/with-warnings/no), watertight/manifold, dimensions & volume, fits-on-bed, wall-thickness estimate vs the 0.4mm nozzle, overhang heuristic. Set full=true for the complete report with EXACT support-material grams/time and infill material-saving deltas from REAL slices (every field labelled exact vs heuristic).

Orientation optimiser: really slices up to 4 candidate build orientations with automatic supports and recommends the one using the LEAST support material (exact, slice-derived), with the filament/time saved vs printing as-is and an estimated price. 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).
