# Run as MCP server (for AI agent integration)
deploydiff mcp- Resource summary: count of creates, updates, deletes, and replaces
- Property-level diffs: what changed, from what to what
- Destructive action highlighting: replaces and deletions called out
- Multi-provider: Terraform, CloudFormation, Pulumi from a single CLI
- Cost impact estimate: before vs. after per resource
- Provider-native pricing: reads Terraform/CFN cost metadata
- Summary row: total monthly change
- Generated rollback commands: reverse the last plan
- Provider-specific: correct syntax for Terraform, CloudFormation
- No manual command construction: eliminates panic-mode mistakes
DeployDiff can run as an MCP (Model Context Protocol) server, letting AI coding agents like Claude Code and Cursor interact with your infrastructure diffs directly:
# Start MCP server (requires click-to-mcp)
deploydiff mcp# Preview changes in CI pipeline
deploydiff preview --tf plan.json
# Check cost impact before deploy
deploydiff cost --tf plan.json
# Generate rollback commands for rapid recovery
deploydiff rollback --tf plan.jsonCombine with shell scripting for pipeline gating:
# Gate on destructive changes (check preview output for destroy actions)
deploydiff preview --tf plan.json | grep -q "destroy"&&echo"WARNING: Contains destructive changes!"# Check cost impact (use --pricing for custom pricing data)
deploydiff cost --tf plan.json --pricing custom-pricing.jsonDeployDiff is one of 11 tools in the Revenue Holdings suite. One license covers all CLI tools.
