elemm 0.5.2

A protocol for autonomous LLM agents to navigate web applications via semantic landmarks.

Elemm (Landmark Protocol)

The Universal AI-Native Backend Bridge. Turn any API into resilient, autonomous AI tools in seconds.

Elemm is a high-performance framework centered around the Model Context Protocol (MCP). It transforms standard REST endpoints into "AI Landmarks", enabling autonomous agents (like Claude or GPT) to discover and interact with your backend with zero-shot precision and self-healing resilience.

Why Elemm? (The Problem with Flat APIs)

Traditional APIs (OpenAPI/Swagger) are built for humans. When you feed a 200-endpoint Swagger file to an LLM:

1. Context Overload: The agent drowns in noise (HTTP codes, headers, internal types).
2. Token Waste: Every turn costs thousands of tokens just for tool descriptions.
3. Fragility: If the AI makes one typo in a parameter, it gets a raw 400 error and gives up.

Elemm solves this with the Landmark-Architecture.

Feature	Standard OpenAPI	Native MCP (Flat)	Elemm (Landmarks)
Noise Level	High (HTTP Metadata)	Medium (Flat-List)	Low (Context Isolated)
Discovery	Static (Manual)	Static (Full Load)	Hierarchical (Drill-Down)
Error Handling	Generic 4xx/5xx	RAW Error	Agent-Repair-Kit (Self-Healing)
Security	Manual Header Logic	Manual	Zero-Config (Auto-Shield)
Max Scale	Limited by Context	~50 Tools	Unlimited (Scale out)
Token Cost	factor 5x	factor 1x	factor < 0.1x (Hygiene)

Key Features

1. Agent-Repair-Kit (Self-Healing)

Elemm is the first protocol that actively talks back to the AI when things go wrong.

• Automated Remedies: If a validation fails (422), Elemm injects your custom remedy instructions into the error response.
• Noise Detection: It explicitly warns the agent if it's hallucinating parameters that don't exist in the manifest.
• Instructional Loops: The AI receives a "behebbar" (fixable) JSON that guides it back to the successful call.

2. Hierarchical Navigation (Context Hygiene)

Stop loading the full API at once. Elemm uses a "Drill-Down" flow:

• Signposts: The agent only sees the "Main Entries" (e.g., explore_logistics, explore_billing).
• Module Loading: Only when the agent enters a module are the specific tools revealed.
• Token Efficiency: This reduces the active context size by up to 90%.

3. Managed Security (Auto-Shield)

Elemm auto-detects HTTPBearer, APIKey, and OAuth2 dependencies.

• Technical credentials are hidden from the agent.
• The protocol marks them as managed_by: protocol.
• Read-Only Mode: Protect your production with a single flag (LANDMARK_READ_ONLY=True) which strips all state-changing actions from the manifest.

Quick Start

1. Installation

pip install elemm

2. Implementation

from elemm import Elemm
from fastapi import FastAPI
from pydantic import BaseModel, Field

app = FastAPI()
ai = Elemm(agent_welcome="Welcome to Solaris-OS.")

class Order(BaseModel):
    item_id: str
    amount: int = Field(..., ge=1, le=100)

@ai.tool(id="get_categories", type="navigation")
@app.get("/categories")
async def list_cats():
    """Discover available product modules."""
    return ["Electronics", "Books"]

@ai.action(
    id="place_order", 
    remedy="Always provide an amount between 1 and 100."
)
@app.post("/order")
async def order(data: Order):
    return {"status": "success"}

# Bind everything
ai.bind_to_app(app)

Decorator Reference

Use the decorators that fit your naming convention – they are all functionally identical aliases of @ai.landmark:

• @ai.tool(id=...): Best for OpenAI / LangChain style.
• @ai.action(id=...): Standard for API-centric logic.
• @ai.landmark(id=...): The precise term for semantic navigation.

Key Options:

• id (Required): The unique name of the tool for the AI.
• type (Default: "read"/"write"): "read", "write", or "navigation".
• remedy: The instruction given to the AI if it fails the validation.
• instructions: Specific rules for this tool (e.g., "Ask for approval first").
• global_access: If True, this tool stays visible even deep inside other modules.

Native MCP Support

Elemm isn't just a manifest; it's a bridge. Use the built-in MCP Server to connect your entire API directly to Claude Desktop, Cursor, or LibreChat.

Claude Desktop Integration

Add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "my-backend": {
      "command": "python3",
      "args": ["/path/to/your/app.py"],
      "env": { "LANDMARK_URLS": "http://localhost:8000" }
    }
  }
}

---

Architecture & Resilience

Elemm is built for scale.

• Reverse Proxy Support: Automatically respects root_path (Nginx/Traefik).
• Circular Ref Safety: Handles complex Pydantic models (self-referencing models).
• ID Sanitization: Safely handles special characters in tags and module names.
