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 Security46
- 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 3 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 check failed: the endpoint is reachable over plaintext HTTP. See how to fix → View diagnostics → Fail
- 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 Usability66
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 800 tokens (~266/item across 3 items; 3 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 Management40
- Stability observed for 12 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage99
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 96% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
How do I install the favicon.zip MCP server?
favicon.zip is a hosted endpoint at https://favicon.zip/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.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. 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 →
check_favicon Check a site's favicon setup ~72
Fetches a URL, probes every icon it declares (root favicon.ico, SVG icon, apple-touch-icon, web manifest), and grades the setup against the modern set. Follow up with generate_favicon to fix what is missing.
| Name | Type | Req | Description |
|---|---|---|---|
| url | string | yes | The site to check, e.g. example.com |
No output schema declared.
No examples provided.
generate_favicon Generate a favicon package ~631
Generates the complete modern favicon set (favicon.ico, icon.svg, apple-touch-icon.png, PWA icons, manifest.webmanifest, favicon-setup.md with the install snippet) from an SVG, an emoji, or short text. Returns a download URL for favicon.zip plus the HTML head snippet to paste. Files follow current best practice: ICO with 16, 32, and 48px layers, a 96px Google Search icon, opaque apple-touch-icon, and a maskable icon with safe-zone padding.
| Name | Type | Req | Description |
|---|---|---|---|
| app_name | string | – | App name written into the web manifest. |
| background | – | – | Icon background: "none" (default), a hex color, or a linear gradient. |
| dark_background | string | – | Hex background for a dark-mode variant; icon.svg then adapts to the browser theme. |
| dark_text_color | string | – | Hex glyph color for the dark-mode variant (text mode). |
| dynamic_module | boolean | – | Add favicon-dynamic.js — badge/progress/spinner with the icon baked in. |
| emoji | string | – | A single emoji character, rendered with Twemoji vector artwork. |
| env_variants | boolean | – | Also emit dev/staging/preview favicon copies with a corner badge. |
| font | string | – | Typeface for text mode: any Google Fonts family name (e.g. "Bangers", "Bebas Neue", "Press Start 2P"), or a bundled id like inter-800, geist-700, silkscreen-400. |
| framework | string | – | Tailors the setup guide: html, nextjs, vite, astro, rails, wordpress. Next.js App Router uses file conventions, not link tags. |
| google_96 | boolean | – | Emit favicon-96x96.png for Google Search results (default true). |
| monochrome | boolean | – | Add a monochrome manifest icon for tinted/badge surfaces. |
| offset_x | number | – | Nudge content horizontally, -0.25 (left) to 0.25 (right). |
| offset_y | number | – | Nudge content vertically, -0.25 (up) to 0.25 (down). |
| padding | number | – | Content inset as a fraction of icon size, -1–0.35. Negative zooms in: the mark scales past the frame and is cropped toward the center (-0.5 renders it at 2x). |
| pwa | boolean | – | Include PWA icons + manifest (default true). |
| radius | number | – | Corner rounding: 0 square, ~0.25 rounded, 1 circle. |
| short_name | string | – | – |
| svg | string | – | Raw SVG markup to use as the icon. The best source when available. |
| text | string | – | 1–4 characters rendered as vector glyphs (e.g. a brand initial like "F"). |
| text_color | string | – | Hex glyph color for text mode, default #0a0a0b. |
| theme_color | string | – | Hex theme color for the manifest. |
No output schema declared.
No examples provided.
get_html_snippet Get the favicon HTML snippet ~97
Returns the modern minimal <head> snippet for favicons, plus placement guidance. Use when the favicon files already exist and only the HTML wiring is needed.
| Name | Type | Req | Description |
|---|---|---|---|
| google_96 | boolean | – | Site ships favicon-96x96.png (default true) |
| has_svg_icon | boolean | – | Site ships an /icon.svg (default true) |
| pwa | boolean | – | Site ships PWA icons + manifest (default true) |
No output schema declared.
