Freeno charge per call

Runs on your machine from its package; the steps are below.

What it does

  1. Reads
  2. Writes
  3. High impact

At most: only reads or looks up information.

What it costs

Free

Odel charges nothing per call. The publisher may charge for its own service.

Runs locally over stdio

This server isn't hosted — your MCP client launches it from a package registry. Use one of the commands below, or drop the config into your client (e.g. Claude Desktop).

npm@sylphx/irisv0.4.1

Run

npx -y @sylphx/iris

MCP client config

{
  "mcpServers": {
    "iris": {
      "command": "npx",
      "args": [
        "-y",
        "@sylphx/iris"
      ]
    }

Iris

Image facts with pixel-level proof.

Dimensions, format, and metadata by default. Local Tesseract OCR only when requested.

The problem

A screenshot is not a paragraph. An agent that guesses the text, the size, or the pixels it never measured will cite something it cannot show.

The difference

The askIris returns
“Read this screenshot.”dimensions, format, metadata, and trust warnings. No OCR unless you ask.
“Read the text.”OCR lines with boxes, only when include_ocr is true or profile is quality.
“What changed between these two captures?”changed pixels and a changed box, when both images are the same size.
“Crop this region.”pixel bounds and a hash. PNG bytes only if include_region_image is true.

Iris does not run a generative vision model. A missing Tesseract binary is a gap, not a made-up transcription.

Install

bash
npx -y @sylphx/iris

That starts a stdio MCP server. No API key. OCR needs the tesseract binary on PATH.

Your clientSetup
Any agent / CLInpx -y @sylphx/iris
Claude Codeclaude mcp add iris -- npx -y @sylphx/iris

{
  "mcpServers": {
    "iris": { "command": "npx", "args": ["-y", "@sylphx/iris"] }
  }
}

A read, then text only if you ask

json
{ "path": "/absolute/path/to/screenshot.png" }

fast, or no profile, returns dimensions, format, metadata, and trust warnings. It does not run OCR.

json
{
  "path": "/absolute/path/to/screenshot.png",
  "include_ocr": true
}

include_ocr: true, or profile: "quality", runs local Tesseract. Explicit include_ocr: false wins over quality. If Tesseract is missing, status stays ok and gaps includes OCR_UNAVAILABLE.

Tools

ToolWhen to call it
read_imageOne local image. Geometry and metadata. OCR only when requested. An optional region crops inside this read.
image_probeFormat, dimensions, pixel count, and source hash. No OCR and no crop.
crop_regionOne citeable region: bounds and hash. Set include_region_image for PNG bytes. No OCR.
compare_imagesChanged pixels between two images of equal dimensions. No OCR.

What it will not pretend

  • GPS fields are always redacted. There is no switch that puts them back.
  • The default file cap is 32 MiB (33,554,432 bytes). A cropped region may not exceed 67,108,864 pixels.
  • compare_images requires equal dimensions. It does not resize either image.
  • OCR lines are {text, bbox, confidence}. The default language is eng.
  • Oversized or undecodable files fail with an error. They are not returned as a successful read.
