Arista CloudVision Portal (CVP) Automation

MCP Server

Field	Value
Repository	noredistribution/mcp-cvp-fun
Transport	stdio (FastMCP)
Python	3.12+
Protocol	HTTPS REST → CloudVision Resource API
Dependencies	fastmcp, httpx, python-dotenv
Install	git clone + uv run (dependencies resolved at runtime)
Entry Point	uv run --with fastmcp fastmcp run /path/to/mcp_server_rest.py
Status	Community demo — not officially supported by Arista

Authentication

CloudVision uses service account tokens passed as HTTP cookies:

1. Log in to CloudVision Portal
2. Navigate to Settings → Service Accounts
3. Create a service account and generate a token
4. Store the token in the .env file as CVPTOKEN

The token is sent as an access_token cookie with every API request (not a Bearer header).

Environment Variables

Variable	Required	Purpose
CVP	Yes	CloudVision instance hostname (e.g., www.arista.io or cvp.example.com)
CVPTOKEN	Yes	Service account token for API authentication

Tools (4)

Device Inventory (1 tool)

Tool	Parameters	Description
get_inventory	—	Get inventory of all devices from CloudVision (hostname, model, serial, version, MAC, IP, streaming status)

Event Monitoring (1 tool)

Tool	Parameters	Description
get_events	—	Get all events from CloudVision (alerts, warnings, informational events with severity, timestamps, device associations)

Connectivity Monitoring (1 tool)

Tool	Parameters	Description
get_connectivity_monitor	—	Get Connectivity Monitor probe statistics (jitter, latency, packet loss, HTTP response time across all probes)

Tag Management (1 tool)

Tool	Parameters	Description
create_tag	tag_name, tag_value	Create a device-level tag in CloudVision via workspace workflow (create workspace → create tag → build → submit)

create_tag Workflow Detail

The create_tag tool follows CloudVision's workspace model — a 5-step process:

1. Create Workspace — POST to /api/resources/workspace/v1/WorkspaceConfig with a UUID-based workspace
2. Create Tag — POST to /api/resources/tag/v2/TagConfig with ELEMENT_TYPE_DEVICE, workspace ID, tag name/value
3. Build Workspace — POST with REQUEST_START_BUILD to validate changes
4. Wait for Build — 10-second wait for build completion
5. Submit Workspace — POST with REQUEST_SUBMIT to apply the tag

CloudVision Resource API Endpoints

Method	Endpoint	Tool
GET	/api/resources/inventory/v1/Device/all	get_inventory
GET	/api/resources/event/v1/Event/all	get_events
GET	/api/resources/connectivitymonitor/v1/ProbeStats/all	get_connectivity_monitor
POST	/api/resources/workspace/v1/WorkspaceConfig	create_tag (workspace create/build/submit)
POST	/api/resources/tag/v2/TagConfig	create_tag (tag creation)

Responses use newline-delimited JSON (NDJSON) format, consistent with CloudVision's streaming resource API.

Workflows

1. Arista Device Discovery

get_inventory → list all Arista devices (hostname, model, serial, version, MAC, IP)
→ Cross-reference with NetBox/Nautobot → flag discrepancies
→ GAIT

2. Arista Event Monitoring

get_events → retrieve all CloudVision events
→ Filter by severity (critical, warning, info)
→ Correlate events with device inventory
→ Severity-sort findings → GAIT

3. Arista Network Health Check

get_inventory → identify all managed devices
→ get_events → check for active alarms and warnings
→ get_connectivity_monitor → analyze jitter, latency, packet loss
→ Correlate connectivity issues with events → severity-sort → GAIT

4. Arista Device Tagging

ServiceNow CR must be in Implement state
→ get_inventory → verify target devices exist
→ create_tag(tag_name, tag_value) → apply device-level tag via workspace workflow
→ get_inventory → verify tag applied
→ GAIT

5. Arista Connectivity Baseline

get_connectivity_monitor → capture current probe statistics
→ Record jitter, latency, packet loss baselines per probe
→ Compare against thresholds → flag degradation
→ GAIT

Guardrails

• Always call get_inventory first — verify CloudVision is reachable and devices are streaming before deeper queries
• Check events before changes — call get_events to identify active issues before any tag operations
• Gate tag creation — all create_tag calls must have a ServiceNow CR in Implement state
• Validate tag names — ensure tag names follow organizational naming conventions before creation
• Monitor connectivity baselines — use get_connectivity_monitor to establish baselines before and after network changes
• Cross-reference inventory — compare CVP device data with NetBox/Nautobot to detect SoT drift
• Record in GAIT — every inventory query, event pull, connectivity check, and tag creation must be logged
• Community project — this is an unofficial demo; evaluate security implications (TLS verification disabled in source) before production use
