AI Landmarks: The specialized protocol for autonomous agent discovery.

Elemm: The Landmark Manifest Protocol

The Infrastructure for the Agentic Web.

Elemm is the Landmark Manifest Protocol, a next-generation communication framework designed to transform how autonomous LLM agents interact with the digital world. Instead of static tool definitions, Elemm provides a dynamic, manifest-driven architecture that enables agents to discover, navigate, and execute complex workflows across distributed APIs with unprecedented efficiency.

Quick Start

1. Install

python3 -m venv .venv
source .venv/bin/activate  # Windows: .venv\Scripts\activate
pip install elemm

2. Generate your MCP Client Configuration

The easiest way to connect your MCP Client (e.g., Cursor, Claude Desktop) is to use the built-in configuration generator. It automatically detects your OS, paths, and WSL environment:

elemm-gateway cfg-gen

Follow the interactive prompts to generate your JSON config snippet, then copy and paste it into your MCP client's configuration file.

3. Start the Dashboard (Optional but Recommended)

Launch the interactive dashboard to monitor tokens, manage credentials (Vault), configure security policies, and generate configs visually:

elemm-dashboard

Open http://localhost:8090 in your browser.

4. Start Discovering

Once connected, tell your agent:

"Use Elemm to connect to https://petstore.swagger.io/v2/swagger.json and list all available pets."

The Gateway provides 9 core tools to the agent. All domain-specific actions are discovered on-the-fly via the Elemm protocol.

5. Build Your Own Landmark Server (Optional)

You can turn any Python function into a high-performance landmark using decorators. Depending on your needs, you can expose these landmarks in two ways:

Option A: FastAPI (Web-based via HTTP/SSE)

Exposes the landmarks as a standard web service / API:

import uvicorn
from fastapi import FastAPI
from elemm import AIProtocolManager, MetadataRegistry
from elemm.gateways.fastapi import FastAPIGateway

app = FastAPI()
registry = MetadataRegistry("landmarks.yaml")
manager = AIProtocolManager(registry=registry)

@manager.landmark("security:quarantine_node")
async def quarantine_node(node_id: str, urgent: bool = False):
    """Quarantines a compromised server node."""
    return {"status": "success", "node": node_id}

# Expose the Elemm manifest and endpoint dynamically on your FastAPI app
gateway = FastAPIGateway(manager)
gateway.bind_to_app(app)

if __name__ == "__main__":
    uvicorn.run(app, host="0.0.0.0", port=8000)

Option B: Standalone MCP (Local via STDIO)

Exposes the landmarks directly as a local STDIO MCP server:

from elemm import ElemmGateway

# Initialize the high-level gateway wrapper
gateway = ElemmGateway(name="MySecurityServer")

@gateway.action("security:quarantine_node")
async def quarantine_node(node_id: str, urgent: bool = False):
    """Quarantines a compromised server node."""
    return {"status": "success", "node": node_id}

# Run directly as a local STDIO MCP Server!
if __name__ == "__main__":
    gateway.run_mcp()

Advanced Usage

• Pydantic Discovery: Elemm automatically generates schemas from Pydantic models.
• Response Hygiene: Built-in _select, _filter, _limit, and _offset parameters prevent context overflow.
• Session Isolation: Use session_id to run parallel tasks without cross-contamination.
• Self-Healing: The SmartRepair engine provides agents with actionable remedies when errors occur.
• Search: Use search_landmarks(query) with Python REGEX to locate tools instantly without full hierarchy traversal.
• Dashboard: Start the dashboard via elemm-dashboard for a real-time observability UI on port 8090.

The Vision: Agentic Web

In the Agentic Web, every API is a "Landmark". Agents no longer need massive, hardcoded system prompts to understand a service. They discover capabilities on-the-fly via a standardized manifest, just like a human navigates a website.

• Unified Discovery: Every Elemm-compliant server exposes its structure at /.well-known/elemm-manifest.md.
• Zero System Prompt: By providing rich semantic landmarks and manifest-driven discovery, you can eliminate thousands of tokens from your system prompts. The protocol is the documentation.
• One MCP Server, Infinite APIs: The built-in Elemm Gateway connects to any OpenAPI, GraphQL, or native Elemm service. A single pip install gives you a universal MCP server that discovers and loads landmarks on-the-fly, allowing you to scale your agent's capabilities without ever restarting your infrastructure.

The Philosophy: Decoupling Intelligence

Elemm is more than just a protocol; it's a shift toward Decentralized Intelligence. In the traditional SaaS model, providers often bundle their APIs with expensive, centralized LLM interfaces. Elemm decouples the "Body" (the API) from the "Brain" (the Agent).

Bring Your Own Agent (BYOA)

With Elemm, API providers only define the Landmarks and Manifests. The user brings their own autonomous agent to the platform. This shifts the computational burden and cost of "reasoning" to the edge—the user's own system.

Sustainability & Efficiency

By eliminating the need for massive, repetitive system prompts and context-heavy tool injections, Elemm significantly reduces the global token footprint of AI interactions.

• Lower Latency: No more waiting for centralized "gatekeeper" models to process 20k tokens of documentation.
• Reduced CO2 & Energy: Fewer tokens mean less GPU compute time, directly translating into a lower carbon footprint for every autonomous task.
• Cost Sovereignty: Providers save on LLM hosting and token costs, while users get the freedom to choose the model that best fits their task and budget.

Core Advantages

Standard protocols like MCP often struggle with large-scale toolsets. Elemm provides a structural solution:

• Efficient Discovery: Agents only see a high-level manifest, loading detailed tool schemas only when needed (on-demand inspection).
• Direct Search: search_landmarks(query) enables regex-based tool discovery without traversing the full hierarchy — ideal for large API surfaces.
• Atomic Sequencing: Execute multiple tool calls in a single LLM turn with native variable piping ($step0.id).
• Multi-Protocol Gateway: Connect to any OpenAPI, GraphQL, or native Elemm service through a single MCP server.
• Security Policy Engine: Built-in Guardian mode with Zero-Trust whitelist, pattern blacklists, landmark restrictions, HTTP method filtering, and Data Loss Prevention.
• SmartRepair Engine: Built-in error handling that provides agents with actionable remedies instead of cryptic stack traces.
• Token Economy: Reduces input tokens by up to 90% in complex forensic and administrative scenarios.
• Observability Dashboard: Optional web UI for real-time monitoring, API exploration, and configuration management.
