Kimi Eyes 👀
中文 | English
Give non-multimodal models in Kimi Code the ability to analyze images and screenshots (inspired by opencode-vision, but thinner: no hooks, no message transforms, no leftover state).
How it works: the plugin declares an MCP stdio server exposing two tools —
read_image (read a local image) and read_clipboard_image (read a clipboard
screenshot) — and a SYSTEM.md guide tells the model when to call them. The server
sends the image to your own vision API (OpenAI-compatible or Anthropic protocol) and
returns the text description.
Multimodal models: paste with Alt+V, see natively — the plugin stays idle.
Non-multimodal models: @image-path / "analyze this screenshot"
→ model calls mcp__kimi-eyes__read_image / read_clipboard_image
→ your VLM returns a description
Prerequisites
- Kimi Code CLI (with
/pluginsand MCP support) - Node.js ≥ 18 (
node --version; nativefetchrequires 18+) - A multimodal vision API of your own (OpenAI-compatible
chat/completions, or Anthropicmessages) — you provide the key
Compatibility
The plugin puts no restriction on your main model. No matter which model your
Kimi Code session is running, or which provider it comes from, as long as it lacks
native image input (image_in), this plugin adds vision to it:
- Common non-multimodal models: DeepSeek (
deepseek-chat), Qwen text-only (qwen-plus/qwen-turbo), Llama text variants, and locally deployed text models (Ollama / vLLM, etc.) - Any third-party model: any OpenAI-compatible or custom model configured in Kimi Code — if it cannot see images natively, the plugin guides it to call the vision tools whenever an image is involved
- Multimodal models: skipped automatically (paste with Alt+V, see natively)
Vision capability is provided by the VLM you configure, fully decoupled from the main model:
| Protocol | Example vision models |
|---|---|
| OpenAI-compatible | qwen-vl series, GLM-4V, GPT-4o / GPT-5 compatible endpoints, Gemini-compatible endpoints, etc. |
| Anthropic | Claude 3.5 / 3.7 / 4 series, etc. |
In short: the main model handles text, the external VLM handles images. When configuring, just pick the protocol that matches your vision API provider (step 1 of the setup wizard); everything else is automatic.
Quick start
1. Install the plugin
In a Kimi Code session (any of these):
# From GitHub (recommended)
/plugins install https://github.com/billowliu2/kimi-eyes
# From a local directory
/plugins install D:\AIGC\Plugin\kimi-eyes
2. Configure the vision API (one-time)
Run the setup wizard (any of these):
# One-shot via npm
npx kimi-eyes setup
# From the local plugin directory
cd D:\AIGC\Plugin\kimi-eyes
node setup.mjs
The wizard walks you through: choose protocol (OpenAI-compatible / Anthropic) → enter Base URL → enter API Key (masked input) → fetch model list and pick a multimodal model → 1×1 image vision check → optionally enter your main model name (for trigger decisions) → write config.
- The model list is fetched from
GET {BaseUrl}/models; entries are tagged "✓vision / text" using the bundled models.dev database, with a "★guess" fallback for models the database does not know; if fetching fails it falls back to manual entry - The vision check must pass before the config is saved, so you never end up with a model that rejects images
- The last step asks for your main model name (optional): the plugin looks it up in models.dev, and if that model supports native image input the tools refuse with a hint — the code-level "multimodal → don't trigger" switch (see Triggering)
- Config is written to
~/.kimi-code/kimi-eyes/config.json(chmod 600on non-Windows systems)
3. Enable
/reload
The MCP server starts automatically with the session.
4. Use it
| Scenario | Action |
|---|---|
| Multimodal model | Paste with Alt+V directly — native vision, plugin not involved |
| Non-multimodal + image path | Type @screenshot.png or paste the path; the model calls read_image |
| Non-multimodal + just screenshotted/copied | Do not Alt+V paste (the CLI rejects pasting on non-multimodal models with Current model does not support image input); just ask "analyze this screenshot" — the model calls read_clipboard_image to read the system clipboard |
| Non-multimodal + paste was rejected | Tell the model "my paste was blocked" — it will switch to read_clipboard_image automatically; no need to save the file |
Want Alt+V pasting? (declare image_in on the model)
Kimi Code's frontend blocks pasting on models that lack image support. Add
image_in to the model in ~/.kimi-code/config.toml:
[models."opencode-go/deepseek-v4-flash"]
capabilities = [ "thinking", "tool_use", "image_in" ] # append image_in
⚠️ Important:
image_inonly lets the frontend accept the paste — it does not mean the provider can actually receive images.
- Declare it only when the provider truly supports image input (e.g. MiniMax-M3, k3, gpt-5.6-luna, grok-4.5) — those models see natively and the plugin stays idle
- Never declare it on text-only providers (e.g. deepseek-v4-flash, GLM text variants): the paste gets accepted, then the request fails at the provider with
400 unknown variant image_url, expected text. The frontend block is a guard.Correct usage for text-only models:
@image-path(read_image) or screenshot and ask directly (read_clipboard_image); if a paste is rejected, tell the model "the paste was blocked" and it will read the clipboard instead. No commands needed.
Activation and triggering
Activation (one-time)
/plugins install D:\AIGC\Plugin\kimi-eyes # 1. Install
/reload # 2. Enable (or start a new session with /new)
Once enabled, the MCP server starts automatically with every session — there is no separate "turn on the feature" step. To verify:
/plugins list→ kimi-eyes should show as enabled/mcp→ the kimi-eyes server should show as connected/plugins info kimi-eyes→ should show no diagnostics errors
Triggering (everyday, fully automatic)
The plugin is passive: SYSTEM.md plants the rules into the model, and the model
calls the tools automatically at the right moment — you do nothing:
| Signal (anything in the message) | Model's automatic behavior |
|---|---|
Image-format path or @ reference (.png/.jpg/.jpeg/.webp/.gif/.bmp) |
Hard trigger: unconditionally calls read_image(path), regardless of wording |
| Media content you cannot interpret (e.g. a pasted image) | Ignores that media part, calls read_clipboard_image() (the pasted image is almost always still in the clipboard) |
| Wording implies image content: image / screenshot / photo / UI / chart / CAPTCHA / OCR, etc., but no path | Calls read_clipboard_image() |
Model natively supports image_in (multimodal) |
Skips all rules, sees images natively, never calls the tools |
Triggering does not depend on fixed wording — the user does not need to say "analyze the image". Image-format paths are an unconditional hard trigger; when in doubt, the model is instructed to call a tool rather than guess.
On model-capability detection: Kimi Code does not expose "is the current model multimodal?" to plugins, so this plugin provides two layers:
- Code-level (recommended): declare
mainModelin the config (last wizard step, or theVISION_MAIN_MODELenvironment variable). The plugin looks it up in the bundled models.dev database — if it supports image input, the tools refuse with a hint ("paste the image directly"); if it is text-only, the tools proceed normally. - Prompt-level: without
mainModel, the SYSTEM.md explicit skip rule handles it (the model recognizes its own capability).
Both layers are fail-safe: a wrong judgment costs at most one wasted external call
(a multimodal model calling a tool) or a missed trigger (a text model — covered by
the path/semantic signals). For a hard switch, simply /plugins disable kimi-eyes
when running multimodal models.
Claude Code usage (optional)
kimi-eyes's MCP server is standard MCP, so it can be mounted directly into Claude
Code. Run the commands below in a system terminal (PowerShell / Git Bash), not
inside Claude Code's own Bash tool (the in-app environment mishandles options
like --scope).
1. Prerequisites
- Node.js ≥ 18
- Claude Code CLI (
claude --version) - A multimodal vision API of your own
2. Mount the MCP server (any of these)
# User-scope (global, all projects)
# Replace <plugin-dir> with the absolute path to kimi-eyes on your machine (e.g. D:\code\kimi-eyes)
claude mcp add --scope user kimi-eyes -- node "<plugin-dir>/mcp/server.mjs"
# Project-scope only
claude mcp add kimi-eyes -- node "<plugin-dir>/mcp/server.mjs"
# npx generic version (no local path; copy-paste on any machine)
claude mcp add --scope user kimi-eyes -- npx --prefer-online -y -p kimi-eyes kimi-eyes-mcp
3. Configure the vision API (one-time)
npx kimi-eyes setup
Same config is shared: kimi-eyes uses
~/.kimi-code/kimi-eyes/config.json(orVISION_*env vars) under both Kimi Code and Claude Code.
4. Guidance rules (CLAUDE.md)
Create (or append to) CLAUDE.md in your project root; the repo root CLAUDE.md
is a ready-made example. Core rules:
# Kimi Eyes — Vision Assist (Claude Code)
Whenever the user's request involves image content and you cannot see it directly:
1. Image path / @ reference → call `mcp__kimi-eyes__read_image` with that path.
2. Just screenshotted/copied, or media you cannot read → call
`mcp__kimi-eyes__read_clipboard_image` (image is almost always still in the clipboard).
3. Wording implies an image but no path → prefer `read_clipboard_image` over guessing.
If your model is multimodal (Claude 3+), you see images natively — ignore these rules.
5. Verify
claude mcp list
# kimi-eyes should show √ Connected
6. Usage
Image file → @C:\path\image.png what's in this?
Screenshot → ask "analyze this screenshot" (model calls read_clipboard_image)
Notes
- Claude 3+ models are natively multimodal, so Claude Code usually sees images directly; the plugin matters for text-only models or when you want a single external VLM
- Uninstall (Claude Code mount): see Uninstall
The first tool call prompts one approval (MCP tool permission): choose Approve
for this session to skip prompts for the rest of the session; for permanent
approval, add to ~/.kimi-code/config.toml:
[[permission.rules]]
decision = "allow"
pattern = "mcp__kimi-eyes__*"
A successful trigger looks like: a tool call appears in the TUI before the answer, and the model then answers based on the returned description. If the model does not call the tool on its own (e.g. you pasted a path without asking a question), just command it: "Call the read_image tool to analyze D:\xxx.png".
Uninstall
Kimi Code plugin
Run the uninstall script from the plugin directory (either way):
# From the local plugin directory
node uninstall.mjs
# One-shot via npm
npx -p kimi-eyes kimi-eyes-uninstall
The script cleans up these leftovers (under KIMI_CODE_HOME or ~/.kimi-code):
- the kimi-eyes entry in
plugins/installed.json(auto-backed-up toinstalled.json.bak.uninstall-*before editing) - the
plugins/managed/kimi-eyes/installed copy - the
kimi-eyes/config.jsonconfig directory (contains your VLM API key; you get a second confirmation before it is deleted)
Flags: --yes skips all confirmations (for scripting); --dry-run only previews,
executes nothing. Re-running is safe (idempotent).
While the plugin is loaded by a running session, the installed-copy directory may not be fully removable — its contents are deleted first, leaving an empty directory shell. After restarting the kimi-code session, clean it up with:
rmdir "C:\Users\<username>\.kimi-code\plugins\managed\kimi-eyes"
Once uninstalled, restart the kimi-code session (or /reload) for it to fully
take effect: the mcp__kimi-eyes__* tools disappear and the SYSTEM.md guidance
rules are no longer injected.
Claude Code mount
claude mcp remove kimi-eyes
Environment variables (optional; override the config file)
| Variable | Description | Priority |
|---|---|---|
VISION_API_PROTOCOL |
openai or anthropic; force the protocol |
Higher than config file |
VISION_API_KEY |
API key | Higher than config file |
VISION_API_URL |
Base URL | Higher than config file |
VISION_MODEL |
Model name | Higher than config file |
VISION_MAIN_MODEL |
Your main model name (optional), used for trigger decisions | Higher than config file |
VISION_MAX_TOKENS |
Max tokens for the vision response (default 1024) | — |
VISION_FETCH_TIMEOUT_MS |
Request timeout in ms (default 60000) | — |
When an environment variable conflicts with
config.json, the variable wins. If neither is set, the tools return a clear error pointing atsetup.mjs. Variable names are compatible with opencode-vision, so migrating is trivial.

| Model list | GET {BaseUrl}/models |
GET {BaseUrl}/v1/models (not an official Anthropic endpoint; falls back to manual entry) |
Model capability database (models.dev)
The plugin ships a slim capability cache mcp/models-db.json synced from
models.dev (currently 279+ models, tagged with whether each
supports image input, ~19 KB). It powers two things:
- Exact tagging in the setup wizard's model picker ("✓vision / text"), replacing pure keyword guessing
- The code-level trigger switch: once
mainModelis declared, the plugin checks whether your main model is multimodal
Sync at packaging time (the data evolves — run before each release):
node scripts/sync-models.mjs
- Source:
https://models.dev/models.json - Behind a proxy: set
HTTPS_PROXY, e.g.HTTPS_PROXY=http://127.0.0.1:7897 node scripts/sync-models.mjs - Options:
--timeout <seconds>(default 180),--out <path>(defaultmcp/models-db.json),--endpoint <URL> - Matching strategy: exact id →
provider/model-namesuffix → case-insensitive name - Unknown models: lookup returns unknown — the wizard falls back to keyword guessing ("★guess") and triggering falls back to the SYSTEM.md rules; nothing breaks
- Manual extras: models.dev does not list every vision model (e.g.
k3-256k,kimi-for-coding). Keep them inEXTRA_ENTRIESinsidescripts/sync-models.mjs— every sync merges them in, so re-syncs never drop them
Version management: package.json is the single source of truth. Before a
release:
npm version patch --no-git-tag-version # bumps package.json; the version hook syncs kimi.plugin.json
npm publish # prepublishOnly syncs models-db automatically
The version hook runs scripts/bump-version.mjs to sync kimi.plugin.json;
the MCP serverInfo.version (mcp/vision.mjs) reads package.json at runtime,
so it never drifts. To bump manually: node scripts/bump-version.mjs 1.0.6.
Tools
| Tool | Arguments | Description |
|---|---|---|
read_image |
path (required), prompt (optional) |
Validates the file is an image (extension + magic bytes), then calls the VLM |
read_clipboard_image |
prompt (optional) |
Captures the clipboard image to a temp file, calls the VLM, deletes the temp file |
Clipboard capture depends on the platform: Windows uses PowerShell (built-in),
macOS needs pngpaste (brew install pngpaste), Linux needs wl-paste (Wayland)
or xclip (X11).
Troubleshooting
- Alt+V paste reports
Current model does not support image input→ that is the Kimi Code CLI rejecting pastes on non-multimodal models. Use@image-path(read_image) instead, or screenshot and ask directly (read_clipboard_imagereads the clipboard) - Tool returns "Vision API is not configured" → run
node setup.mjs, or setVISION_API_KEY/VISION_API_URL/VISION_MODEL - Model list fetch fails (404/401) → the wizard falls back to manual entry; if
your provider has no
/modelsendpoint, just type the model name - Vision check fails → pick a model that really accepts image input (e.g.
qwen-vl-max,glm-4v,gpt-4o,claude-3-5-sonnet— check your provider's docs) read_clipboard_imageerrors → make sure the clipboard actually holds an image (Ctrl+C an image or Win+Shift+S a screenshot first); on macOS/Linux check the platform tool above is installed- Tools not showing up after install → verify the plugin is enabled
(
/plugins list) and run/reloador start a new session
Security notes
config.jsonstores your API key in plain text (600perms on non-Windows); never commit it to a repositoryread_clipboard_imagereads the system clipboard — it may contain sensitive content you just copied. The tool call goes through the approval flow, so you decide when it runs- This project ships no credentials; vision requests go only to the Base URL you configured
Limitations
- No subagent delegation: Kimi Code's
model_preferenceonly supports primary/secondary (it cannot name a specific vision model the way opencode can), so the value is limited - No
UserPromptSubmithook fallback: theSYSTEM.mdguide covers the common cases; if paste/reference behavior misbehaves in your TUI, a hook can be re-evaluated then
