 ## 🚀 Overview
 
-**FuzzForge OSS** is an open-source runtime that enables AI agents (GitHub Copilot, Claude, etc.) to orchestrate security research workflows through the **Model Context Protocol (MCP)**.
+**FuzzForge AI** is an open-source MCP server that enables AI agents (GitHub Copilot, Claude, etc.) to orchestrate security research workflows through the **Model Context Protocol (MCP)**.
 
-### The Core: Modules
+FuzzForge connects your AI assistant to **MCP tool hubs** — collections of containerized security tools that the agent can discover, chain, and execute autonomously. Instead of manually running security tools, describe what you want and let your AI assistant handle it.
 
-At the heart of FuzzForge are **modules** - containerized security tools that AI agents can discover, configure, and orchestrate. Each module encapsulates a specific security capability (static analysis, fuzzing, crash analysis, etc.) and runs in an isolated container.
+### The Core: Hub Architecture
 
-- **🔌 Plug & Play**: Modules are self-contained - just pull and run
-- **🤖 AI-Native**: Designed for AI agent orchestration via MCP
-- **🔗 Composable**: Chain modules together into automated workflows
-- **📦 Extensible**: Build custom modules with the Python SDK
+FuzzForge acts as a **meta-MCP server** — a single MCP endpoint that gives your AI agent access to tools from multiple MCP hub servers. Each hub server is a containerized security tool (Binwalk, YARA, Radare2, Nmap, etc.) that the agent can discover at runtime.
 
-The OSS runtime handles module discovery, execution, and result collection. Security modules (developed separately) provide the actual security tooling - from static analyzers to fuzzers to crash triagers.
+- **🔍 Discovery**: The agent lists available hub servers and discovers their tools
+- **🤖 AI-Native**: Hub tools provide agent context — usage tips, workflow guidance, and domain knowledge
+- **🔗 Composable**: Chain tools from different hubs into automated pipelines
+- **📦 Extensible**: Add your own MCP servers to the hub registry
 
-Instead of manually running security tools, describe what you want and let your AI assistant handle it.

+Agent → Binwalk:  Extract filesystem from firmware image
+Agent → YARA:     Scan extracted files for vulnerability patterns
+Agent → Radare2:  Trace dangerous function calls in prioritized binaries
+Agent → Report:   8 vulnerabilities found (2 critical, 4 high, 2 medium)
+```
 
 ### 🎬 Use Case: Rust Fuzzing Pipeline
 
 > **Scenario**: Fuzz a Rust crate to discover vulnerabilities using AI-assisted harness generation and parallel fuzzing.

-## 📦 Modules
+## 🧑‍💻 Usage
 
-FuzzForge modules are containerized security tools that AI agents can orchestrate. The module ecosystem is designed around a simple principle: **the OSS runtime orchestrates, enterprise modules execute**.
+Once installed, just talk to your AI agent:
 
-### Module Ecosystem
-
-| | FuzzForge OSS | FuzzForge Enterprise Modules |
-|---|---|---|
-| **What** | Runtime & MCP server | Security research modules |
-| **License** | Apache 2.0 | BSL 1.1 (Business Source License) |
-| **Compatibility** | ✅ Runs any compatible module | ✅ Works with OSS runtime |
-
-**Enterprise modules** are developed separately and provide production-ready security tooling:
-
-| Category | Modules | Description |
-|----------|---------|-------------|
-| 🔍 **Static Analysis** | Rust Analyzer, Solidity Analyzer, Cairo Analyzer | Code analysis and fuzzable function detection |
-| 🎯 **Fuzzing** | Cargo Fuzzer, Honggfuzz, AFL++ | Coverage-guided fuzz testing |
-| 💥 **Crash Analysis** | Crash Triager, Root Cause Analyzer | Automated crash deduplication and analysis |
-| 🔐 **Vulnerability Detection** | Pattern Matcher, Taint Analyzer | Security vulnerability scanning |
-| 📝 **Reporting** | Report Generator, SARIF Exporter | Automated security report generation |
-
-> 💡 **Build your own modules!** The FuzzForge SDK allows you to create custom modules that integrate seamlessly with the OSS runtime. See [Creating Custom Modules](#-creating-custom-modules).
-
-### Execution Modes
-
-Modules run in two execution modes:
-
-#### One-shot Execution
-
-Run a module once and get results:
-
-```python
-result = execute_module("my-analyzer", assets_path="/path/to/project")
+```
+"What security tools are available?"
+"Scan this firmware image for vulnerabilities"
+"Analyze this binary with radare2"
+"Run nuclei against https://example.com"
 ```
 
-#### Continuous Execution
+The agent will use FuzzForge to discover the right hub tools, chain them into a pipeline, and return results — all without you touching a terminal.
 
-For long-running tasks like fuzzing, with real-time metrics:
-
-```python
-# Start continuous execution
-session = start_continuous_module("my-fuzzer", 
-    assets_path="/path/to/project",
-    configuration={"target": "my_target"})
-
-# Check status with live metrics
-status = get_continuous_status(session["session_id"])
-
-# Stop and collect results
-stop_continuous_module(session["session_id"])
-```
-
----
-
-## 🛠️ Creating Custom Modules
-
-Build your own security modules with the FuzzForge SDK:
-
-```python
-from fuzzforge_modules_sdk import FuzzForgeModule, FuzzForgeModuleResults
-
-class MySecurityModule(FuzzForgeModule):
-    def _run(self, resources):
-        self.emit_event("started", target=resources[0].path)
-        
-        # Your analysis logic here
-        results = self.analyze(resources)
-        
-        self.emit_progress(100, status="completed", 
-            message=f"Analysis complete")
-        return FuzzForgeModuleResults.SUCCESS
-```
-
-📖 See the [Module SDK Guide](fuzzforge-modules/fuzzforge-modules-sdk/README.md) for details.
+See the [Usage Guide](USAGE.md) for detailed setup and advanced workflows.

-## Building Modules
+## Terminal UI
 
-FuzzForge modules are containerized security tools. After cloning, you need to build them once:
+FuzzForge ships with a terminal user interface (TUI) built on [Textual](https://textual.textualize.io/) for managing AI agents and MCP hub servers from a single dashboard.
 
-### Build All Modules
+### Launching the UI
 
 ```bash
-# From the fuzzforge-oss directory
-make build-modules
+uv run fuzzforge ui
 ```
 
-This builds all available modules:
-- `fuzzforge-rust-analyzer` - Analyzes Rust code for fuzzable functions
-- `fuzzforge-cargo-fuzzer` - Runs cargo-fuzz on Rust crates
-- `fuzzforge-harness-validator` - Validates generated fuzzing harnesses
-- `fuzzforge-crash-analyzer` - Analyzes crash inputs
+### Dashboard
 
-### Build a Single Module
+The main screen is split into two panels:
 
-```bash
-# Build a specific module
-cd fuzzforge-modules/rust-analyzer
-make build
-```
+| Panel | Content |
+|-------|---------|
+| **AI Agents** (left) | Shows GitHub Copilot, Claude Desktop, and Claude Code with live link status and config file path |
+| **Hub Servers** (right) | Shows all configured MCP hub tools with Docker image name, source hub, and build status (✓ Ready / ✗ Not built) |
 
-### Verify Modules are Built
+### Keyboard Shortcuts
 
-```bash
-# List built module images
-docker images | grep fuzzforge
-```
+| Key | Action |
+|-----|--------|
+| `Enter` | **Select** — Act on the selected row (setup/unlink an agent) |
+| `h` | **Hub Manager** — Open the hub management screen |
+| `r` | **Refresh** — Re-check all agent and hub statuses |
+| `q` | **Quit** |
 
-You should see something like:
-```
-fuzzforge-rust-analyzer    0.1.0    abc123def456    2 minutes ago    850 MB
-fuzzforge-cargo-fuzzer     0.1.0    789ghi012jkl    2 minutes ago    1.2 GB
-...
-```
+### Agent Setup
+
+Select an agent row in the AI Agents table and press `Enter`:
+
+- **If the agent is not linked** → a setup dialog opens asking for your container engine (Docker or Podman), then installs the FuzzForge MCP configuration
+- **If the agent is already linked** → a confirmation dialog offers to unlink it (removes the `fuzzforge` entry without touching other MCP servers)
+
+The setup auto-detects:
+- FuzzForge installation root
+- Docker/Podman socket path
+- Hub configuration from `hub-config.json`
+
+### Hub Manager
+
+Press `h` to open the hub manager. This is where you manage your MCP hub repositories:
+
+| Button | Action |
+|--------|--------|
+| **FuzzingLabs Hub** | One-click clone of the official [mcp-security-hub](https://github.com/FuzzingLabs/mcp-security-hub) repository — clones to `~/.fuzzforge/hubs/mcp-security-hub`, scans for tools, and registers them in `hub-config.json` |
+| **Link Path** | Link any local directory as a hub — enter a name and path, FuzzForge scans it for `category/tool-name/Dockerfile` patterns |
+| **Clone URL** | Clone any git repository and link it as a hub |
+| **Remove** | Unlink the selected hub and remove its servers from the configuration |
+
+The hub table shows:
+- **Name** — Hub name (★ prefix for the default hub)
+- **Path** — Local directory path
+- **Servers** — Number of MCP tools discovered
+- **Source** — Git URL or "local"

-## MCP Server Configuration
+## MCP Hub System
 
-FuzzForge integrates with AI agents through the Model Context Protocol (MCP). Configure your preferred AI agent to use FuzzForge tools.
+### What is an MCP Hub?
+
+An MCP hub is a directory containing one or more containerized MCP tools, organized by category:
+
+```
+my-hub/
+├── category-a/
+│   ├── tool-1/
+│   │   └── Dockerfile
+│   └── tool-2/
+│       └── Dockerfile
+├── category-b/
+│   └── tool-3/
+│       └── Dockerfile
+└── ...
+```
+
+FuzzForge scans for the pattern `category/tool-name/Dockerfile` and auto-generates server configuration entries for each discovered tool.
+
+### FuzzingLabs Security Hub
+
+The default MCP hub is [mcp-security-hub](https://github.com/FuzzingLabs/mcp-security-hub), maintained by FuzzingLabs. It includes **40+ security tools** across categories:
+
+| Category | Tools |
+|----------|-------|
+| **Reconnaissance** | nmap, masscan, shodan, zoomeye, whatweb, pd-tools, externalattacker, networksdb |
+| **Binary Analysis** | binwalk, yara, capa, radare2, ghidra, ida |
+| **Code Security** | semgrep, rust-analyzer, harness-tester, cargo-fuzzer, crash-analyzer |
+| **Web Security** | nuclei, nikto, sqlmap, ffuf, burp, waybackurls |
+| **Fuzzing** | boofuzz, dharma |
+| **Exploitation** | searchsploit |
+| **Secrets** | gitleaks |
+| **Cloud Security** | trivy, prowler, roadrecon |
+| **OSINT** | maigret, dnstwist |
+| **Threat Intel** | virustotal, otx |
+| **Password Cracking** | hashcat |
+| **Blockchain** | medusa, solazy, daml-viewer |
+
+**Clone it via the UI:**
+
+1. `uv run fuzzforge ui`
+2. Press `h` → click **FuzzingLabs Hub**
+3. Wait for the clone to finish — servers are auto-registered
+
+**Or clone manually:**
+
+```bash
+git clone git@github.com:FuzzingLabs/mcp-security-hub.git ~/.fuzzforge/hubs/mcp-security-hub
+```
+
+### Linking a Custom Hub
+
+You can link any directory that follows the `category/tool-name/Dockerfile` layout:
+
+**Via the UI:**
+
+1. Press `h` → **Link Path**
+2. Enter a name and the directory path
+
+**Via the CLI (planned):** Not yet available — use the UI.
+
+### Building Hub Images
+
+After linking a hub, you need to build the Docker images before the tools can be used:
+
+```bash
+# Build all images from the default security hub
+./scripts/build-hub-images.sh
+
+# Or build a single tool image
+docker build -t semgrep-mcp:latest mcp-security-hub/code-security/semgrep-mcp/
+```
+
+The dashboard hub table shows ✓ Ready for built images and ✗ Not built for missing ones.

+
+## MCP Server Configuration (CLI)
+
+If you prefer the command line over the TUI, you can configure agents directly:
 
 ### GitHub Copilot
 
 ```bash
-# That's it! Just run this command:
 uv run fuzzforge mcp install copilot
 ```
 
-The command auto-detects everything:
-- **FuzzForge root** - Where FuzzForge is installed
-- **Modules path** - Defaults to `fuzzforge-oss/fuzzforge-modules`
-- **Docker socket** - Auto-detects `/var/run/docker.sock`
+The command auto-detects:
+- **FuzzForge root** — Where FuzzForge is installed
+- **Docker socket** — Auto-detects `/var/run/docker.sock`
 
-**Optional overrides** (usually not needed):

 ## Using FuzzForge with AI
 
-Once MCP is configured, you interact with FuzzForge through natural language with your AI assistant.
+Once MCP is configured and hub images are built, interact with FuzzForge through natural language with your AI assistant.
 
 ### Example Conversations
 
 **Discover available tools:**
 ```
-You: "What FuzzForge modules are available?"
-AI: Uses list_modules → "I found 4 modules: rust-analyzer, cargo-fuzzer, 
-    harness-validator, and crash-analyzer..."
+You: "What security tools are available in FuzzForge?"
+AI: Queries hub tools → "I found 15 tools across categories: nmap for 
+    port scanning, binwalk for firmware analysis, semgrep for code 
+    scanning, cargo-fuzzer for Rust fuzzing..."
 ```
 
-**Analyze code for fuzzing targets:**
+**Analyze a binary:**
+```
+You: "Extract and analyze this firmware image"
+AI: Uses binwalk to extract → yara for pattern matching → capa for 
+    capability detection → "Found 3 embedded filesystems, 2 YARA 
+    matches for known vulnerabilities..."
+```
+
+**Fuzz Rust code:**
 ```
 You: "Analyze this Rust crate for functions I should fuzz"
-AI: Uses execute_module("rust-analyzer") → "I found 3 good fuzzing candidates:
-    - parse_input() in src/parser.rs - handles untrusted input
-    - decode_message() in src/codec.rs - complex parsing logic
-    ..."
-```
+AI: Uses rust-analyzer → "Found 3 fuzzable entry points..."
 
-**Generate and validate harnesses:**
-```
-You: "Generate a fuzzing harness for the parse_input function"
-AI: Creates harness code, then uses execute_module("harness-validator") 
-    → "Here's a harness that compiles successfully..."
-```
-
-**Run continuous fuzzing:**
-```
 You: "Start fuzzing parse_input for 10 minutes"
-AI: Uses start_continuous_module("cargo-fuzzer") → "Started fuzzing session abc123"
-
-You: "How's the fuzzing going?"
-AI: Uses get_continuous_status("abc123") → "Running for 5 minutes:
-    - 150,000 executions
-    - 2 crashes found
-    - 45% edge coverage"
-
-You: "Stop and show me the crashes"
-AI: Uses stop_continuous_module("abc123") → "Found 2 unique crashes..."
+AI: Uses cargo-fuzzer → "Fuzzing session started. 2 crashes found..."
 ```
 
-### Available MCP Tools
-
-| Tool | Description |
-|------|-------------|
-| `list_modules` | List all available security modules |

-| `list_continuous_sessions` | List all active sessions |
-| `get_execution_results` | Retrieve results from an execution |
-| `execute_workflow` | Run a multi-step workflow |
+**Scan for vulnerabilities:**
+```
+You: "Scan this codebase with semgrep for security issues"
+AI: Uses semgrep-mcp → "Found 5 findings: 2 high severity SQL injection 
+    patterns, 3 medium severity hardcoded secrets..."
+```

 FuzzForge is a security research orchestration platform. Use these tools to:
 
-1. **List modules**: Discover available security research modules
-2. **Execute modules**: Run modules in isolated containers
-3. **Execute workflows**: Chain multiple modules together
+1. **List hub servers**: Discover registered MCP tool servers
+2. **Discover tools**: Find available tools from hub servers
+3. **Execute hub tools**: Run security tools in isolated containers
 4. **Manage projects**: Initialize and configure projects
 5. **Get results**: Retrieve execution results
 
 Typical workflow:
 1. Initialize a project with `init_project`
-2. Set project assets with `set_project_assets` (optional, only needed once for the source directory)
-3. List available modules with `list_modules`
-4. Execute a module with `execute_module` — use `assets_path` param to pass different inputs per module
-5. Read outputs from `results_path` returned by `execute_module` — check module's `output_artifacts` metadata for filenames
+2. Set project assets with `set_project_assets` — path to the directory containing
+   target files (firmware images, binaries, source code, etc.)
+3. List available hub servers with `list_hub_servers`
+4. Discover tools from servers with `discover_hub_tools`
+5. Execute hub tools with `execute_hub_tool`
+
+Agent context convention:
+When you call `discover_hub_tools`, some servers return an `agent_context` field
+with usage tips, known issues, rule templates, and workflow guidance. Always read
+this context before using the server's tools.
+
+File access in containers:
+- Assets set via `set_project_assets` are mounted read-only at `/app/uploads/` and `/app/samples/`
+- A writable output directory is mounted at `/app/output/` — use it for extraction results, reports, etc.
+- Always use container paths (e.g. `/app/uploads/file`) when passing file arguments to hub tools
+
+Stateful tools:
+- Some tools (e.g. radare2-mcp) require multi-step sessions. Use `start_hub_server` to launch
+  a persistent container, then `execute_hub_tool` calls reuse that container. Stop with `stop_hub_server`.
+
+Firmware analysis pipeline (when analyzing firmware images):
+1. **binwalk-mcp** (`binwalk_scan` + `binwalk_extract`) — identify and extract filesystem from firmware
+2. **yara-mcp** (`yara_scan_with_rules`) — scan extracted files with vulnerability rules to prioritize targets
+3. **radare2-mcp** (persistent session) — confirm dangerous code paths
+4. **searchsploit-mcp** (`search_exploitdb`) — query version strings from radare2 against ExploitDB
+   Run steps 3 and 4 outputs feed into a final triage summary.
+
+radare2-mcp agent context (upstream tool — no embedded context):
+- Start a persistent session with `start_hub_server("radare2-mcp")` before any calls.
+- IMPORTANT: the `open_file` tool requires the parameter name `file_path` (with underscore),
+  not `filepath`. Example: `execute_hub_tool("hub:radare2-mcp:open_file", {"file_path": "/app/output/..."})`
+- Workflow: `open_file` → `analyze` → `list_imports` → `xrefs_to` → `run_command` with `pdf @ <addr>`.
+- Static binary fallback: firmware binaries are often statically linked. When `list_imports`
+  returns an empty result, fall back to `list_symbols` and search for dangerous function names
+  (system, strcpy, gets, popen, sprintf) in the output. Then use `xrefs_to` on their addresses.
+- For string extraction, use `run_command` with `iz` (data section strings).
+  The `list_all_strings` tool may return garbled output for large binaries.
+- For decompilation, use `run_command` with `pdc @ <addr>` (pseudo-C) or `pdf @ <addr>`
+  (annotated disassembly). The `decompile` tool may fail with "not available in current mode".
+- Stop the session with `stop_hub_server("radare2-mcp")` when done.
