# Cloudflare Control Plane Registry Enhancement Summary
|
|
|
|
## ✅ Enhanced Capability Registry (v1.0.1)
|
|
|
|
**Key improvements implemented:**
|
|
|
|
### 1. **Exact MCP Tool Names & Entrypoints**
|
|
- **Cloudflare Safe**: `cf_snapshot`, `cf_refresh`, `cf_config_diff`, etc.
|
|
- **WAF Intelligence**: `waf_capabilities`, `waf_analyze`, `waf_assess`, etc.
|
|
- **Oracle Answer**: `oracle_answer`
|
|
- **Entrypoints**: Exact Python module paths for execution
|
|
|
|
### 2. **Operational Metadata**
|
|
- **Auth/Env**: Required environment variables per server
|
|
- **Side Effects**: Clear indication of read-only vs. mutating operations
|
|
- **Outputs**: Specific output formats (JSON, Terraform HCL, GitOps MRs)
|
|
|
|
### 3. **Drift Prevention**
|
|
- **Tools section**: Exact MCP tool names prevent registry/source mismatch
|
|
- **Entrypoint specification**: Prevents confusion between modules and runnable servers
|
|
- **File references**: Uses actual file names (e.g., `invariant_checker_py.py`)
|
|
|
|
### 4. **Machine-Checkable Contract**
|
|
The registry now serves as a **verifiable contract** between:
|
|
- **Documentation**: What capabilities are claimed
|
|
- **Implementation**: What tools are actually exposed
|
|
- **Operations**: What side effects and auth are required
|
|
|
|
## 🎯 Registry Structure
|
|
|
|
### MCP Server Template
|
|
```yaml
|
|
server_name:
|
|
module: "exact.python.module.path"
|
|
entrypoint: "runnable.server.path"
|
|
purpose: "clear operational purpose"
|
|
tools: ["exact_tool_name (operation_type)"]
|
|
auth_env: ["REQUIRED_VARS"]
|
|
side_effects: "read-only | propose | mutate"
|
|
outputs: ["json", "terraform_hcl", "gitops_mr"]
|
|
```
|
|
|
|
### GitOps Tool Template
|
|
```yaml
|
|
tool_name:
|
|
file: "exact/file/path.py"
|
|
purpose: "specific operational function"
|
|
side_effects: "creates MRs | applies changes | generates reports"
|
|
outputs: ["terraform_apply", "gitops_mr", "anomaly_report"]
|
|
```
|
|
|
|
## 🔒 Audit-Grade Features
|
|
|
|
### Compliance Validation
|
|
- **Tool enumeration**: Every MCP tool is explicitly listed
|
|
- **Access control**: Auth requirements clearly documented
|
|
- **Change tracking**: Versioned registry with generation timestamps
|
|
|
|
### Operational Transparency
|
|
- **Side effects**: Clear about mutating vs. read-only operations
|
|
- **Output formats**: Specific about what each component produces
|
|
- **Dependencies**: Environmental requirements explicitly stated
|
|
|
|
### Drift Detection
|
|
- **File references**: Uses actual file names to prevent rename drift
|
|
- **Module paths**: Exact Python module paths prevent import confusion
|
|
- **Tool names**: Exact MCP tool names prevent capability mismatch
|
|
|
|
## 🚀 Usage Examples
|
|
|
|
### For Auditors
|
|
```bash
|
|
# Verify MCP server capabilities match documentation
|
|
cat capability_registry_v2.json | jq '.mcp_servers.cloudflare_safe.tools'
|
|
|
|
# Check operational requirements
|
|
cat capability_registry_v2.json | jq '.mcp_servers.cloudflare_safe.auth_env'
|
|
```
|
|
|
|
### For Developers
|
|
```bash
|
|
# Validate new MCP server against registry template
|
|
python3 generate_capability_registry_v2.py
|
|
|
|
# Check for capability drift
|
|
diff capability_registry_v2.json capability_registry.json
|
|
```
|
|
|
|
### For Operations
|
|
```bash
|
|
# Verify side effects before deployment
|
|
cat capability_registry_v2.json | jq '.mcp_servers.cloudflare_safe.side_effects'
|
|
|
|
# Check output formats for integration
|
|
cat capability_registry_v2.json | jq '.gitops_tools.waf_rule_proposer.outputs'
|
|
```
|
|
|
|
## 📊 Registry Files Generated
|
|
|
|
1. **`capability_registry_v2.json`** - Machine-readable contract
|
|
2. **`CAPABILITY_REGISTRY_V2.md`** - Human-readable documentation
|
|
3. **`generate_capability_registry_v2.py`** - Regeneration script
|
|
|
|
## 🎯 Next Steps
|
|
|
|
### Continuous Validation
|
|
- Add CI check to validate MCP tool names against registry
|
|
- Automated drift detection between registry and source code
|
|
- Periodic registry regeneration as capabilities evolve
|
|
|
|
### Extended Metadata
|
|
- Add performance characteristics (timeouts, rate limits)
|
|
- Include error handling patterns
|
|
- Add recovery procedures for failed operations
|
|
|
|
### Integration Testing
|
|
- Use registry to generate comprehensive test suites
|
|
- Validate auth/env requirements in test environment
|
|
- Verify side effects and outputs match expectations
|
|
|
|
This enhanced registry transforms the Cloudflare control plane from **documented infrastructure** to **verifiable, auditable, and drift-resistant infrastructure**. |
