io.github.echology-io/decompose is a MCP server that deterministically decomposes text into authority, risk, and attention semantic units without an LLM.

About

io.github.echology-io/decompose is a Model Context Protocol server that splits arbitrary text into classified semantic units—highlighting authority, risk, and attention—using deterministic logic rather than an LLM. developers who paste large terms of service, security policies, customer emails, or spec dumps into agents can register this tool so the agent receives structured segments first, which often improves review quality and reduces repeated full-document prompts. It fits Ship review workflows and Validate scoping when documents are dense, and Operate when triaging incident narratives. The catalog lists a PyPI stdio package without mandatory API keys, which keeps local setup lightweight. It complements reasoning models; it does not replace legal advice, compliance sign-off, or semantic search across your codebase.

  • Decomposes text into classified semantic units without calling an LLM
  • Labels dimensions include authority, risk, and attention per description
  • PyPI package decompose-mcp with stdio MCP transport
  • Useful preprocessing step to cut token cost and add structure upstream of the model
  • Registry version 0.1.1; GitHub source at echology-io/decompose

What it does

Break long text into classified semantic units (authority, risk, attention) deterministically—no LLM—for safer agent preprocessing.

Who is it for?

Best when you want cheap, repeatable text segmentation before LLM analysis of policies, specs, or support escalations.

Skip if: Skip if you need full legal interpretation, embeddings search, or LLM-native summarization as the only step.

What you get

After adding the MCP server, the agent can preprocess text into labeled units for tighter review, scoping, and triage workflows.

  • Classified semantic units with authority, risk, and attention facets
  • Structured input for follow-on agent reasoning steps
  • Lower-token workflows by segmenting before full LLM passes

By the numbers

  • PyPI identifier decompose-mcp version 0.1.1
  • Transport: stdio
  • Explicitly no LLM in server description

Decompose

CI PyPI Python

Stop prompting. Start decomposing.

Deterministic text classification for AI agents. Decompose turns any text into classified, structured semantic units — instantly. No LLM. No setup. One function call.


Before: your agent reads this

The contractor shall provide all materials per ASTM C150-20. Maximum load
shall not exceed 500 psf per ASCE 7-22. Notice to proceed within 14 calendar
days of contract execution. Retainage of 10% applies to all payments.
For general background, the project is located in Denver, CO...

After: your agent reads this

[
  {
    "text": "The contractor shall provide all materials per ASTM C150-20.",
    "authority": "mandatory",
    "risk": "compliance",
    "type": "requirement",
    "irreducible": true,
    "attention": 8.0,
    "entities": ["ASTM C150-20"]
  },
  {
    "text": "Maximum load shall not exceed 500 psf per ASCE 7-22.",
    "authority": "prohibitive",
    "risk": "safety_critical",
    "type": "constraint",
    "irreducible": true,
    "attention": 10.0,
    "entities": ["ASCE 7-22"]
  }
]

Every unit classified. Every standard extracted. Every risk scored. Your agent knows what matters.


Install

pip install decompose-mcp

Use as MCP Server

Add to your agent's MCP config (Claude Code, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "decompose": {
      "command": "uvx",
      "args": ["decompose-mcp", "--serve"]
    }
  }
}

Your agent gets two tools:

  • decompose_text — decompose any text
  • decompose_url — fetch a URL and decompose its content

OpenClaw

Install the skill from ClawHub or configure directly:

{
  "mcpServers": {
    "decompose": {
      "command": "python3",
      "args": ["-m", "decompose", "--serve"]
    }
  }
}

Or install the skill: clawdhub install decompose-mcp

Use as CLI

# Pipe text
cat spec.txt | decompose --pretty

# Inline
decompose --text "The contractor shall provide all materials per ASTM C150-20."

# Compact output (smaller JSON)
cat document.md | decompose --compact

Use as Library

from decompose import decompose_text, filter_for_llm

result = decompose_text("The contractor shall provide all materials per ASTM C150-20.")

for unit in result["units"]:
    print(f"[{unit['authority']}] [{unit['risk']}] {unit['text'][:60]}...")

# Pre-filter for LLM context — keep only high-value units
filtered = filter_for_llm(result, max_tokens=4000)
print(f"{filtered['meta']['reduction_pct']}% token reduction")
llm_input = filtered["text"]  # Ready for your LLM

What Each Field Means

Field Values What It Tells Your Agent
authority mandatory, prohibitive, directive, permissive, conditional, informational Is this a hard requirement or background?
risk safety_critical, security, compliance, financial, contractual, advisory, informational How much does this matter?
type requirement, definition, reference, constraint, narrative, data What kind of content is this?
irreducible true/false Must this be preserved verbatim?
attention 0.0 - 10.0 How much compute should the agent spend here?
entities standards, codes, regulations What formal references are cited?
actionable true/false Does someone need to do something?

What to Build With This

Decompose is not the destination. It's the step before the LLM that most developers skip — not because it's hard, but because nobody showed them it exists. Documents have structure. That structure is classifiable. And classification should happen before reasoning.

Without:  document → chunk → embed → retrieve → LLM → answer  (100% of tokens)
With:     document → decompose → filter/route → LLM → answer  (20-40% of tokens)

Filter: built-in LLM pre-filter

filter_for_llm() keeps mandatory, safety-critical, financial, and compliance units — drops boilerplate before it reaches your LLM or vector store.

from decompose import decompose_text, filter_for_llm

result = decompose_text(open("contract.md").read())
filtered = filter_for_llm(result, max_tokens=4000)

# filtered["text"] = high-value units only, ready for LLM
# filtered["meta"]["reduction_pct"] = how much was dropped (typically 60-80%)

# Or use the units directly for embedding
for unit in filtered["units"]:
    embed_and_store(unit["text"], metadata={
        "authority": unit["authority"],
        "risk": unit["risk"],
        "attention": unit["attention"],
    })

Route: risk-based processing

Safety-critical content goes to one chain. Financial content goes to another. Boilerplate gets skipped.

from decompose import decompose_text

result = decompose_text(spec_text)

for unit in result["units"]:
    if unit["risk"] == "safety_critical":
        safety_chain.process(unit)       # Full analysis + human review
    elif unit["risk"] == "financial":
        audit_chain.process(unit)         # Flag for finance team
    elif unit["attention"] < 0.5:
        pass                              # Skip boilerplate
    else:
        general_chain.process(unit)       # Standard LLM analysis

Measure: token cost reduction

from decompose import decompose_text

result = decompose_text(spec_text)
total = len(result["units"])
high = [u for u in result["units"] if u["attention"] >= 1.0]

print(f"{len(high)}/{total} units need LLM analysis")
print(f"{100 - len(high) * 100 // total}% token reduction")

See examples/ for runnable scripts.


Why No LLM?

Decompose runs on pure regex and heuristics. No Ollama, no API key, no GPU, no inference cost.

This is intentional:

  • Fast: <500ms for a 50-page spec
  • Deterministic: Same input always produces same output
  • Offline: Works air-gapped, on a plane, on CI
  • Composable: Your agent's LLM reasons over the structured output — decompose handles the preprocessing

The LLM is what your agent uses. Decompose makes whatever model you're running work better.


Built by Echology

Decompose is built by Echology and extracted from AECai, a document intelligence platform for Architecture, Engineering, and Construction firms. The classification patterns, entity extraction, and irreducibility detection are battle-tested against thousands of real AEC documents — specs, contracts, RFIs, inspection reports, pay applications.

Decompose earned its independence — it started as AECai's text classification module, proved general enough to work across domains (insurance, trading, regulatory), and was released standalone. Free, MIT-licensed.

Case Study: Open Scripture Intelligence

The same chunking and entity extraction patterns that classify engineering specs also structure the Bible. Open Scripture Intelligence uses Decompose's Markdown-aware chunker and regex entity extraction to transform 31,100 verses into a knowledge graph with 344,799 cross-reference edges and semantic embeddings — proving the methodology is domain-agnostic.
