About Edison.watch 🏢

Edison helps you gain observability, control, and policy enforcement for all AI interactions with systems of records, existing company software and data. Prevent AI from causing data leakage, lightning-fast setup for cross-system governance.

Quick Start 🚀

The fastest way to get started:

# Installs uv (via Astral installer) and launches open-edison with uvx.
# Note: This does NOT install Node/npx. Install Node if you plan to use npx-based tools like mcp-remote.
curl -fsSL https://raw.githubusercontent.com/Edison-Watch/open-edison/main/curl_pipe_bash.sh | bash

Run locally with uvx: uvx open-edison That will run the setup wizard if necessary.

⬇️ Install Node.js/npm (optional for MCP tools)

If you need npx (for Node-based MCP tools like mcp-remote), install Node.js as well:

• uv: curl -fsSL https://astral.sh/uv/install.sh | sh
• Node/npx: brew install node

• uv: curl -fsSL https://astral.sh/uv/install.sh | sh
• Node/npx: sudo apt-get update && sudo apt-get install -y nodejs npm

• uv: powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
• Node/npx: winget install -e --id OpenJS.NodeJS

After installation, ensure that npx is available on PATH.

Install from PyPI

Prerequisites

• Pipx/uvx

# Using uvx
uvx open-edison

# Using pipx
pipx install open-edison
open-edison

Run with a custom config directory:

open-edison run --config-dir ~/edison-config
# or via environment variable
OPEN_EDISON_CONFIG_DIR=~/edison-config open-edison run

Run with Docker

There is a dockerfile for simple local setup.

# Single-line:
git clone https://github.com/Edison-Watch/open-edison.git && cd open-edison && make docker_run

# Or
# Clone repo
git clone https://github.com/Edison-Watch/open-edison.git
# Enter repo
cd open-edison
# Build and run
make docker_run

The MCP server will be available at http://localhost:3000 and the api + frontend at http://localhost:3001. 🌐

⚙️ Run from source

1. Clone the repository:

git clone https://github.com/Edison-Watch/open-edison.git
cd open-edison

1. Set up the project:

make setup

1. Edit config.json to configure your MCP servers. See the full file: config.json, it looks like:

{
  "server": { "host": "0.0.0.0", "port": 3000, "api_key": "..." },
  "logging": { "level": "INFO", "database_path": "sessions.db" },
  "mcp_servers": [
    { "name": "filesystem", "command": "uvx", "args": ["mcp-server-filesystem", "/tmp"], "enabled": true },
    { "name": "github", "enabled": false, "env": { "GITHUB_PERSONAL_ACCESS_TOKEN": "..." } }
  ]
}

1. Run the server:

make run
# or, from the installed package
open-edison run

The server will be available at http://localhost:3000. 🌐

🔌 MCP Connection

Connect any MCP client to Open Edison (requires Node.js/npm for npx):

npx -y mcp-remote http://localhost:3000/mcp/ --http-only --header "Authorization: Bearer your-api-key"

Or add to your MCP client config:

{
  "mcpServers": {
    "open-edison": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "http://localhost:3000/mcp/", "--http-only", "--header", "Authorization: Bearer your-api-key"]
    }
  }
}

🧭 Usage

API Endpoints

See API Reference for full API documentation.

🛠️ Development

Setup 🧰

Setup from source as above.

Run ▶️

Server doesn't have any auto-reload at the moment, so you'll need to run & ctrl-c this during development.

make run

Tests/code quality ✅

We expect make ci to return cleanly.

make ci

⚙️ Configuration (config.json)

Configuration ⚙️

The config.json file contains all configuration:

• server.host - Server host (default: localhost)
• server.port - Server port (default: 3000)
• server.api_key - API key for authentication
• logging.level - Log level (DEBUG, INFO, WARNING, ERROR)
• mcp_servers - Array of MCP server configurations

Each MCP server configuration includes:

• name - Unique name for the server
• command - Command to run the MCP server
• args - Arguments for the command
• env - Environment variables (optional)
• enabled - Whether to auto-start this server

🔐 How Edison prevents data leakages

🔱 The lethal trifecta, agent lifecycle management

Open Edison includes a comprehensive security monitoring system that tracks the "lethal trifecta" of AI agent risks, as described in Simon Willison's blog post:

1. Private data access - Access to sensitive local files/data
2. Untrusted content exposure - Exposure to external/web content
3. External communication - Ability to write/send data externally

The configuration allows you to classify these risks across tools, resources, and prompts using separate configuration files.

In addition to trifecta, we track Access Control Level (ACL) for each tool call, that is, each tool has an ACL level (one of PUBLIC, PRIVATE, or SECRET), and we track the highest ACL level for each session. If a write operation is attempted to a lower ACL level, it is blocked.

🧰 Tool Permissions (tool_permissions.json)

Defines security classifications for MCP tools. See full file: tool_permissions.json, it looks like:

{
  "_metadata": { "last_updated": "2025-08-07" },
  "builtin": {
    "get_security_status": { "enabled": true, "write_operation": false, "read_private_data": false, "read_untrusted_public_data": false, "acl": "PUBLIC" }
  },
  "filesystem": {
    "read_file": { "enabled": true, "write_operation": false, "read_private_data": true, "read_untrusted_public_data": false, "acl": "PRIVATE" },
    "write_file": { "enabled": true, "write_operation": true, "read_private_data": true, "read_untrusted_public_data": false, "acl": "PRIVATE" }
  }
}

📁 Resource Permissions (`resource_permissions.json`)

Resource Permissions (resource_permissions.json)

Defines security classifications for resource access patterns. See full file: resource_permissions.json, it looks like:

{
  "_metadata": { "last_updated": "2025-08-07" },
  "builtin": { "config://app": { "enabled": true, "write_operation": false, "read_private_data": false, "read_untrusted_public_data": false } }
}

💬 Prompt Permissions (`prompt_permissions.json`)

Prompt Permissions (prompt_permissions.json)

Defines security classifications for prompt types. See full file: prompt_permissions.json, it looks like:

{
  "_metadata": { "last_updated": "2025-08-07" },
  "builtin": { "summarize_text": { "enabled": true, "write_operation": false, "read_private_data": false, "read_untrusted_public_data": false } }
}

Wildcard Patterns ✨

All permission types support wildcard patterns:

• Tools: server_name/* (e.g., filesystem/* matches all filesystem tools)
• Resources: scheme:* (e.g., file:* matches all file resources)
• Prompts: type:* (e.g., template:* matches all template prompts)

Security Monitoring 🕵️

All items must be explicitly configured - unknown tools/resources/prompts will be rejected for security.

Use the get_security_status tool to monitor your session's current risk level and see which capabilities have been accessed. When the lethal trifecta is achieved (all three risk flags set), further potentially dangerous operations are blocked.
