OpenEdison 🔒⚡️

Deterministic Agentic Data Firewall

Agentic AI breaks traditional data security. OpenEdison secures & unifies agent data access to stop data leaks by securing your agent's interactions with your data/software.

Gain visibility, monitor potential threats, and get alerts on the data your agent is reading/writing.

How is it different from other MCP Gateways? Read our MCP Gateway Comparison Blog and our OpenEdison release post.

OpenEdison helps address the lethal trifecta problem, which can increase risks of agent hijacking & data exfiltration by malicious actors.

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.

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.

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

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. 🌐

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"},
  "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. 🌐

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"]
    }
  }
}

Open-Edison comes preconfigured with ngrok for easy ChatGPT integration. Follow these steps to connect:

🔐 How Edison reduces data leakages

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 can be blocked based on your configuration.

🧰 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)

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)

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.
