How do I use Nautobot MCP Server v2?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Nautobot MCP Server v2 list all cables in data center A" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

Nautobot MCP Server v2

Enhanced Nautobot 3.1.0 integration for NetClaw — GraphQL reads, REST writes, ITSM-gated changes, live-vs-SoT reconciliation.

Replaces the v1 mcp-nautobot (5 IPAM-only REST tools) with 13 tools covering devices, interfaces, VLANs, prefixes, IP addresses, cables, raw GraphQL, write operations, and reconciliation.

Architecture

Reads: GraphQL API (POST /api/graphql/) — efficient field selection, nested relationships
Writes: REST API (POST/PATCH /api/dcim/*, /api/ipam/*) — Nautobot 3.1.0 has no GraphQL mutations
Transport: stdio (FastMCP)
