About Steganography MCP
Steganography MCP is an MCP server in the Files category: 128-tool MCP server for steganography analysis — LSB detection, chi-square steganalysis, RS analysis, JPEG/F5/JSteg/OutGuess detection, BPCS, video & GIF stego, network covert channels, MP3 stego, spread spectrum, archive stego, QR code analysis, audio stego, text encoding, file forensics. 100% offline, zero API keys.
Install
git clone https://github.com/badchars/steganography-mcpThis server has no ConduID identity, so agent calls to it are not receipted. Pin the version you install and review the source before granting it credentials.
Tools (13)
img_appended_dataDetect and extract data appended after the image EOF marker. Checks for hidden data past PNG IEND, JPEG EOI, or BMP file size boundary
Parameters not published.
img_bitplaneExtract and visualize a specific bit plane from an image channel. Shows dimensions, percentage of 1-bits, and an ASCII art preview
Parameters not published.
img_channel_analysisPer-channel statistical analysis for R, G, B, and A channels. Reports mean, standard deviation, entropy, min, max, and unique value count
Parameters not published.
img_chi_squareChi-square steganalysis attack on each color channel independently. Detects LSB replacement by testing whether adjacent pixel value pairs are equalized
Parameters not published.
img_comparePixel-by-pixel comparison of two images. Reports identical/different pixel counts, max difference, and which channels are affected
Parameters not published.
img_detectAuto-detect steganography in an image. Runs chi-square, RS analysis, entropy, metadata, appended data, and tool signature checks. Returns a comprehensive JSON report
Parameters not published.
img_entropy_mapPer-block entropy analysis of an image. Splits the image into blocks and calculates Shannon entropy per block, flagging high-entropy regions
Parameters not published.
img_histogramGenerate a pixel value histogram with anomaly detection. Detects Pairs-of-Values (PoV) anomalies that indicate LSB steganography
Parameters not published.
img_lsb_detectStatistical LSB steganography detection. Runs chi-square and sample pair analysis on each color channel independently
Parameters not published.
img_lsb_embedEmbed a message into an image using LSB steganography. Reads a PNG file, embeds the message into the least significant bits, and writes a new PNG file
Parameters not published.

img_lsb_extractExtract hidden data from image LSBs. Extracts bits from specified channels and bit plane, attempts UTF-8 decode, and shows hex dump
Parameters not published.
img_metadataDeep metadata extraction from an image. For PNG: text chunks, chunk list, IHDR info. For JPEG: EXIF, comments, quantization tables, marker list
Parameters not published.
img_rs_analysisRS (Regular-Singular) steganalysis using the Fridrich-Goljan-Du method. Analyzes pixel groups to estimate LSB embedding rate per channel
Parameters not published.
