# Testing list_organizations Tool
## ✅ Implementation Complete
I've created the `list_organizations` tool following the exact pattern from the documentation.
---
## 📁 Files Created/Modified
### 1. **Tool Implementation**
- **File**: `src/mcp_server/tools/organizations/list_organizations.py`
- **Lines**: 300+ lines with full documentation
- **Pattern**: Follows `TOOL_DEVELOPMENT_TEMPLATE.md` exactly
### 2. **RBAC Configuration**
- **File**: `src/core/security.py` (line 170)
- **Change**: Added `"list_organizations"` to `ORGANIZATION_TOOLS`
- **Effect**: Tool is now accessible to Org-level users and Global Admins
### 3. **Package Init**
- **File**: `src/mcp_server/tools/organizations/__init__.py`
- **Purpose**: Makes the package discoverable
---
## 🎯 What I Implemented (From Documentation)
### From RBAC_IMPLEMENTATION_ANALYSIS.md:
✅ **Stage 1: Tool Visibility (RBAC)**
- Tool added to `ORGANIZATION_TOOLS` category
- Only Org-level users and Global Admins can see this tool
- Platform and Dealership users won't see it in their available tools
✅ **Stage 2: Permission Check**
```python
required_permission = "organization.show"
if required_permission not in (user_context.permissions or []):
return error("Missing required permission")
```
✅ **Stage 3: Data Filtering (Hierarchy)**
```python
# Global Admin: Sees ALL organizations
# Org-level users: See only THEIR organization
filtered_organizations = RBAC.filter_data_by_hierarchy(...)
if not user_context.is_global_admin:
filtered_organizations = [
org for org in filtered_organizations
if org.get("id") == user_context.organization_id
]
```
✅ **Stage 4: N/A (Read-only tool)**
- No write/delete actions needed
---
## 🔄 Request Flow (From ARCHITECTURE_FLOW.md)
```
User: "Show me all organizations"
↓
Web Chat API: Extract Bearer token → Get cached user
↓
Orchestrator: Filter tools by RBAC
├─ Global Admin: ✅ list_organizations available
├─ Org Admin: ✅ list_organizations available
├─ Platform Admin: ❌ Tool not visible (RBAC filtered)
└─ Dealership Admin: ❌ Tool not visible (RBAC filtered)
↓
LLM: Chooses list_organizations tool
↓
Tool Execution:
1. Check permission: "organization.show" ✅
2. Call Laravel: GET /api/v2/list-organizations/
3. Filter by hierarchy:
- Global Admin → All organizations
- Org Admin → Only their organization
4. Return envelope response
↓
LLM: "You have access to 1 organization: Sai SinglePoint Org..."
```

## 🧪 Testing
### Test 1: Global Admin (Sees All Organizations)
```bash
curl -X POST http://localhost:8002/chat \
-H "Content-Type: application/json" \
-H "Authorization: Bearer GLOBAL_ADMIN_TOKEN" \
-d '{
"message": "Show me all organizations"
}'
```
**Expected Result:**
- Tool is visible to LLM ✅
- Permission check passes ✅
- Returns ALL organizations from Laravel
- No hierarchy filtering (Global Admin)
---
### Test 2: Org Admin (Sees Only Their Org)
```bash
curl -X POST http://localhost:8002/chat \
-H "Content-Type: application/json" \
-H "Authorization: Bearer ORG_ADMIN_TOKEN" \
-d '{
"message": "Show me my organization details"
}'
```
**Expected Result:**
- Tool is visible to LLM ✅
- Permission check passes (has organization.show) ✅
- Returns organizations from Laravel
- Filtered to only organization_id = user's org ✅
---
### Test 3: Platform Admin (Tool Not Available)
```bash
curl -X POST http://localhost:8002/chat \
-H "Content-Type: application/json" \
-H "Authorization: Bearer PLATFORM_ADMIN_TOKEN" \
-d '{
"message": "Show me all organizations"
}'
```
**Expected Result:**
- Tool is NOT visible to LLM ❌ (RBAC filtered)
- LLM responds: "I don't have access to list organizations"
- Tool never executes
---
### Test 4: Org Viewer (Has Permission)
```bash
curl -X POST http://localhost:8002/chat \
-H "Content-Type: application/json" \
-H "Authorization: Bearer ORG_VIEWER_TOKEN" \
-d '{
"message": "What organization am I in?"
}'
```
**Expected Result:**
- Tool is visible to LLM ✅ (Org-level user)
- Permission check passes (Org Viewer has organization.show) ✅
- Returns only their organization
- Read-only (no write actions needed)
---
### Test 5: Org User WITHOUT Permission (Edge Case)
If an Org User somehow doesn't have `organization.show` permission:
**Expected Result:**
- Tool is visible to LLM ✅ (RBAC allows)
- Permission check FAILS ❌
- Returns: `{"missing_reason": "Missing required permission: organization.show"}`
- LLM tells user they lack permission
---
## 📊 What Each Role Sees
| Role | Tool Visible? | Permission Check | Data Returned |
|------|---------------|------------------|---------------|
| **Global Admin** | ✅ Yes | ✅ Pass | All organizations |
| **Org Admin** | ✅ Yes | ✅ Pass | Their organization only |
| **Org Manager** | ✅ Yes | ✅ Pass | Their organization only |
| **Org User** | ✅ Yes | ✅ Pass | Their organization only |
| **Org Viewer** | ✅ Yes | ✅ Pass | Their organization only |
| **Platform Admin** | ❌ No | N/A | N/A (tool filtered) |
| **Platform User** | ❌ No | N/A | N/A (tool filtered) |
| **Dealership Admin** | ❌ No | N/A | N/A (tool filtered) |
| **Dealership User** | ❌ No | N/A | N/A (tool filtered) |

## 🔍 Code Walkthrough
### 1. Permission Check (Lines 60-75)
```python
# From RBAC_IMPLEMENTATION_ANALYSIS.md - Strategy 2: Laravel Permission Check
required_permission = "organization.show"
if required_permission not in (user_context.permissions or []):
return wrap_response(
tool_name="list_organizations",
trace_id=trace_id,
data={"organizations": [], "total": 0},
missing_reason=f"Missing required permission: {required_permission}"
)
```
**Why this works:**
- `user_context.permissions` contains Laravel permissions array
- Checked from your database: All org-level roles have `organization.show`
- Returns safe error if permission missing
---
### 2. Laravel API Call (Lines 77-115)
```python
# From TOOL_DEVELOPMENT_TEMPLATE.md - Step 2: Call Laravel API
url = f"{settings.laravel_api_url}/api/v2/list-organizations/"
headers = {
"Authorization": f"Bearer {user_context.bearer_token}", # ← From cached user
"Content-Type": "application/json",
"Accept": "application/json"
}
async with httpx.AsyncClient(timeout=30.0) as client:
response = await client.get(url, headers=headers, params=params)
response.raise_for_status()
data = response.json()
```
**Why this works:**
- Uses `user_context.bearer_token` (cached from authentication)
- Laravel validates token and returns data
- Proper error handling with `raise_for_status()`
---
### 3. Hierarchy Filtering (Lines 117-145)
```python
# From ARCHITECTURE_FLOW.md - Stage 3: Data Filtering
filtered_organizations = RBAC.filter_data_by_hierarchy(
data=organizations,
user_context=user_context,
org_field="id", # Organization's own ID
platform_field="platform_id",
dealership_field="dealership_id"
)
# Additional filtering for non-global admins
if not user_context.is_global_admin:
filtered_organizations = [
org for org in filtered_organizations
if org.get("id") == user_context.organization_id
]
```
**Why this works:**
- `RBAC.filter_data_by_hierarchy()` handles basic filtering
- Additional check ensures non-admins only see their org
- Global Admins bypass this filter (see all orgs)
---
### 4. Envelope Response (Lines 147-160)
```python
# From wrap_response pattern
return wrap_response(
tool_name="list_organizations",
trace_id=trace_id,
data={
"organizations": filtered_organizations,
"total": len(filtered_organizations),
"message": f"Successfully retrieved {len(filtered_organizations)} organization(s)"
}
)
```
**Why this works:**
- Consistent response format for LLM
- Includes metadata (total count, message)
- LLM can parse and present nicely to user
---
### 5. Auto-Registration (Lines 180-260)
```python
def register(mcp):
"""Auto-discovered by src/mcp_server/tools/__init__.py"""
@mcp.tool(name="list_organizations", description="...")
async def list_organizations_tool(
# Tool params
glo_platform_id: str = "all",
# User context (auto-injected)
user_id: int = 0,
bearer_token: str = "",
permissions: list = None,
...
):
# Create UserContext
user_context = UserContext(...)
# Call logic
return await list_organizations_logic(user_context, ...)
```
**Why this works:**
- `register()` function is auto-discovered
- Orchestrator injects all user context params
- Clean separation: wrapper vs. logic
---
## 📈 Performance
Based on BEARER_TOKEN_AUTH.md:
- **First request**: ~150ms (calls Laravel for user data)
- **Cached requests**: ~10ms (user data cached)
- **Tool execution**: ~50-100ms (Laravel API call)
- **Total**: ~200ms average
---
## ✅ Checklist (From READY_TO_BUILD.md)
- [x] ✅ Calls Laravel API with bearer_token
- [x] ✅ Checks appropriate Laravel permission (`organization.show`)
- [x] ✅ Filters data by hierarchy (Global Admin vs. Org users)
- [x] ✅ Handles viewer roles (read-only, no write check needed)
- [x] ✅ Handles errors gracefully (HTTP errors, exceptions)
- [x] ✅ Returns envelope response
- [x] ✅ Logs all actions (info, warning, error)
- [x] ✅ Added to RBAC category (`ORGANIZATION_TOOLS`)
- [x] ✅ Auto-discovered by MCP (has `register()` function)

## 🎓 Key Implementation Details
### From RBAC_IMPLEMENTATION_ANALYSIS.md:
1. **No Laravel Middleware Needed** ✅
- MCP architecture handles this better
- RBAC filters tools before LLM sees them
- Permission checks happen in tool code
2. **Bearer Token Authentication** ✅
- Token validated once at API entry
- Cached for 15 minutes
- Passed to tools for Laravel API calls
3. **Hierarchy-Aware Filtering** ✅
- Global Admin: All data
- Org-level: Their org only
- Platform/Dealership: N/A (tool not visible)
4. **Laravel Permissions Integration** ✅
- Permissions array passed to tools
- Checked with simple `in` operator
- Matches your database permissions exactly
---
## 🚀 Next Steps
The tool is **ready to use**! To test:
1. **Start the servers**:
```bash
# Terminal 1: MCP Server
python -m src.mcp_server.server
# Terminal 2: Web Chat API
python -m src.web_chat.main
```
2. **Test with cURL** (see examples above)
3. **Check logs**:
- Look for `list_organizations_called`
- Check `organizations_filtered_by_hierarchy`
- Verify permission checks
4. **Build more tools**:
- Use this as template
- Follow same pattern
- Copy-paste and modify
