mm-ctx 0.8.1

Fast, multimodal context for agents.

mm-ctx

Fast, multimodal context for agents

---

Familiar UNIX CLI tools like find, grep, cat — with multimodal powers.

mm offers both a CLI and a Python API that enable agents to work with file types that LLMs can't natively read, including images, video, audio, PDFs, and other binary formats. Rust core for speed, Python for dev-ex, UNIX philosophy for composability.

Installation

# with pip
pip install mm-ctx

# with uv
uv pip install mm-ctx

# or run directly without installing
uvx --from mm-ctx mm --help

Alternative methods

# macOS / Linux (shell installer)
curl -LsSf https://vlm-run.github.io/mm/install/install.sh | sh

# Windows (PowerShell)
irm https://vlm-run.github.io/mm/install/install.ps1 | iex

CLI

Commands that mirror familiar Unix tools but operate on multimodal semantics. Indexing is implicit — every command auto-builds a metadata index on first use.

Metadata commands (find, wc with --format json) run in ~60ms on 700 files via the Rust fast path.

$ mm cat mm-samples/bench.jpg -m accurate

<description>
This outdoor daytime photograph captures a peaceful park scene on a sunny day. The primary focus is a modern dark gray metal slat bench  positioned in the foreground on a patch of green grass. The bench is set upon a small concrete pad, and its curved backrest and armrests  create a sleek, contemporary silhouette. Behind the bench, a paved walkway cuts through a well-maintained lawn.

Quick start

mm --version                                                    # print version
mm find mm-samples/ --tree --depth 1                            # directory overview with sizes
mm wc mm-samples/ --by-kind                                     # file/byte/token counts by kind

# PDF — text extraction (no LLM needed)
mm cat wordpress-pdf-invoice-plugin-sample.pdf                  # extract text
mm cat wordpress-pdf-invoice-plugin-sample.pdf -n 20            # first 20 lines

# Image / Video / Audio — require a configured LLM profile
mm cat bench.jpg -m accurate                                    # LLM caption
mm cat Timelapse.mp4 -m accurate                                # keyframe mosaic → LLM description
mm cat mp3_44100Hz_320kbps_stereo.mp3 -m accurate               # Whisper transcript → LLM summary
mm cat wordpress-pdf-invoice-plugin-sample.pdf -m accurate      # LLM-structured invoice

Python API

mm is also a library. mm.Context is the one class you need to build a multimodal prompt incrementally, then hand the whole thing to a VLM. Backed by a Rust core: O(1) insert/lookup, sub-millisecond render at 10K items.

The public namespace is intentionally tiny:

import mm
mm.Context              # the one class you use
mm.Ref                  # Annotated[str, "mm.Ref"] typed alias for ref ids
mm.RefNotFoundError     # KeyError subclass raised by ctx.get on miss
mm.uuid7()              # UUIDv7 helper (time-ordered default session_id)

Build a prompt

import mm
from pathlib import Path
from PIL import Image

ctx = mm.Context(session_id=mm.uuid7())      # or omit; auto-mints a UUIDv7

img:  mm.Ref = ctx.put(Path("photo.jpg"))
img2: mm.Ref = ctx.put(Image.open("x.png"),
                       metadata={"note": "product hero shot"})
doc:  mm.Ref = ctx.put(Path("paper.pdf"),
                       metadata={"summary": "Attention is all you need",
                                 "tags": ["nlp", "transformer"]})
vid:  mm.Ref = ctx.put(Path("clip.mp4"),
                       metadata={"scene": 3, "actor": "A"})

ctx.put(obj, *, metadata=...) accepts a pathlib.Path, a str (file path or http(s):// URL), bytes, or a PIL.Image.Image. metadata is a single free-form JSON-serialisable dict — note / summary / tags are conventional keys used by rendering surfaces; anything else flows through to the VLM as a leading text block per item. Every put returns a short kind-prefixed ref id like img_a1b2c3, typed as mm.Ref.

Emit VLM-ready messages (OpenAI / Gemini)

from openai.types.chat import ChatCompletionMessageParam
from google.genai import types as genai_types

messages_openai: list[ChatCompletionMessageParam] = ctx.to_messages(format="openai")
messages_gemini: list[genai_types.ContentDict]    = ctx.to_messages(format="gemini")

Drop messages_openai directly into client.chat.completions.create(messages=...), or messages_gemini into model.generate_content(contents=...). Per-kind encoder overrides:

messages: list[ChatCompletionMessageParam] = ctx.to_messages(
    format="openai",
    encoders={"image": "tile", "video": "mosaic"},
)

Unspecified kinds fall back to sensible defaults (image-resize, video-frame-sample, document-rasterize).

Round-trip and resolve

obj: Path | Image.Image | bytes | str = ctx.get(img)   # instance: returns the stored object
row: dict | None = mm.Context.get(f"{ctx.session_id}/{img}")  # classmethod: cross-session DB lookup

Instance ctx.get(ref) returns the exact Python object you put — identity is preserved for in-memory items (no copy, no rehydrate). Classmethod mm.Context.get("<session>/<ref>") resolves against the global ~/.local/share/mm/mm.db when you only have a ref string and no live Context.

Missed a ref? ctx.get("img_a1b2cZ") raises mm.RefNotFoundError (a KeyError subclass) with a Levenshtein-based "did you mean" and the full context table inline — agent-friendly by default.

Render

ctx.print_tree()                  # insertion-order tree with metadata
print(ctx.to_md(mode="fast"))     # markdown: ref | kind | source | content
print(repr(ctx))                  # markdown summary: ref | kind | source

Context(session=019da4…, items=4)
├── [1] img_a1b2c3  image     /abs/path/photo.jpg
├── [2] img_9f0e12  image     PIL.Image(RGB, 1024×768)

Context("~/data") continues to support the directory-scan surface (to_polars, to_pandas, to_arrow, sql, show, info). See docs/api.md for the full spec — print_tree layouts, cross-session resolution, and the deferred save() API.

Output modes

• TTY: Rich formatted tables/panels
• Piped: plain TSV/text (machine-readable, no ANSI)
• **--format json**: JSON output on any command that supports it
• **--format csv**: Comma-separated values
• **--format dataset-jsonl**: JSONL for dataset export
• **--format dataset-hf**: HuggingFace Datasets format (requires --output-dir)

Verbose mode (--verbose / -v)

mm cat <file> [OPTIONS] --verbose shows the pipeline execution tree after content:

pipeline
  ├─ encode: resize · 0.0s → 1 parts (1 image)
  └─ generate: ollama · 2.3s · 354→195 tokens

Processing Modes

Mode	What	Speed	How
fast (default)	Local extraction — text from PDF, image hash/EXIF, video metadata	<100ms/file	pypdfium2 (PDF), Rust mmap (images), mp4parse/matroska (video)
accurate	LLM-powered semantic understanding (captions, descriptions, summaries)	Varies	LLM API via active profile + pipeline config

Metadata scanning (find, wc) always uses Rust-native extraction (~60ms / 700 files).

Performance

Benchmarked on Apple Silicon (M-series), 702 files (7.2GB):

Operation	Latency
Metadata scan (702 files)	8ms
CLI cold start (find --format json)	60ms
CLI cold start (find --schema --format json)	109ms
CLI cold start (sql)	300ms
Fast code extraction	~52ms
Fast image extraction	~61ms
Fast PDF text extraction	~220ms
Fast video metadata	<100ms
PDF page mosaic (per page)	~10ms
Video keyframe mosaic (48 frames)	~1s

Storage

mm uses a global SQLite database at ~/.local/share/mm/mm.db with sqlite-vec for vector search:

Table	Contents	Relationship
files	File metadata + content (one row per file, uri = absolute path)	—
l2_results	LLM-generated summaries (many per file)	FK → files.uri
chunks	~2048-char content chunks	FK → l2_results.id
chunks_vec	Embedding vectors (sqlite-vec virtual table)	FK → chunks.id
cache	Key-value result cache	—

The files table includes metadata columns (path, size, kind, etc.) and content columns (content_hash, text_preview, line_count, duration_s, exif_*, video_codec, etc.).

Use mm config reset-db to clear all databases and caches.

Pipelines — encode + generate

Pipelines are YAML configs under pipelines/{kind}/{mode}.yaml that pair an encoder with optional LLM generation parameters. When generate is null, the pipeline is encode-only (no LLM call). Encoders are Python classes under encoders/ that convert media files into VLM-ready Messages. See [docs/PIPELINES.md](docs/PIPELINES.md) and [docs/ENCODERS.md](docs/ENCODERS.md) for the full pipeline and encoder reference.

Pipeline fields can be overridden from the CLI:

mm cat photo.jpg -m accurate --encode.strategy tile --generate.max-tokens 1024
mm cat photo.jpg -m accurate --generate.temperature 0.5

# Override individual strategy_opts entries (repeatable KEY=VALUE form;
# values are coerced to int/float/bool when possible).
mm cat photo.jpg -m accurate --encode.strategy_opts max_width=768
mm cat video.mp4 -m accurate --encode.strategy_opts max_width=768 --encode.strategy_opts fps=5

# Print a built-in pipeline's YAML as a starting point for your own.
mm cat --print-pipeline image/accurate

Load explicit pipeline YAML(s) with -p (repeatable, dispatched by kind field):

mm cat photo.jpg -p my-image-pipeline.yaml
mm cat *.jpg *.mp4 -p image-pipeline.yaml -p video-pipeline.yaml
mm cat photo.jpg -p ~/custom.yaml --generate.max-tokens 512

Custom pipeline paths can also be set in ~/.config/mm/mm.toml:

[pipelines]
image.fast = "/path/to/my-image-fast.yaml"
video.accurate = "/path/to/my-video-accurate.yaml"

LLM Configuration using Profiles

For accurate mode, mm uses the openai Python SDK to call any OpenAI-compatible API. Provider settings are managed through profiles — named configurations stored in ~/.config/mm/mm.toml.

Quick setup

mm config init                # create config with default profile (local Ollama)
mm config show                # show resolved config with sources

Managing profiles

Each profile stores base_url, api_key, and model. You can have as many as you need — one per provider, one per use-case, etc.

# Add custom profiles
mm profile add openai --base-url https://api.openai.com/v1 --api-key sk-... --model gpt-4o
mm profile add openrouter --base-url https://openrouter.ai/api/v1 --model qwen/qwen3.5-27b

# Update reserved profiles (ollama, gemini, vlmrun)
mm profile update ollama --base-url http://localhost:11434 --model qwen3.5:9B

# List all profiles (● = active)
mm profile list

# Switch the active profile
mm profile use openai

# Update a field on an existing profile
mm profile update openai --model gpt-4o-mini --api-key sk-new-key

# Remove a profile (cannot remove the active one)
mm profile remove openai

Selecting a profile per-command

# --profile flag (one-off override, does not change active profile)
mm --profile openai cat photo.png -m accurate

# Environment variable
MM_PROFILE=openai mm cat photo.png -m accurate

Resolution order

Provider settings (base_url, api_key, model) come from the active profile, falling back to built-in defaults.

The active profile is resolved as:

--profile flag  >  MM_PROFILE env  >  active_profile in config file  >  "ollama"

Config file format

# ~/.config/mm/mm.toml
active_profile = "ollama"

[profile.ollama]
base_url = "http://localhost:11434"
api_key = ""
model = "qwen3.5:0.8"

[profile.gemini]
base_url = "https://openrouter.ai/api/v1"
api_key = "<OPENROUTER_API_KEY>"
model = "google/gemini-2.5-flash-lite"

[profile.vlmrun]
base_url = "https://api.vlm.run/v1/openai"
api_key = "<VLMRUN_API_KEY>"
model = "Qwen/Qwen3.5-0.8B"
