What is the Caddy Server MCP Server?
Connect your Caddy Server instance to any AI agent and automate your web infrastructure management through natural conversation.
What you can do
- Configuration Management — Load, get, append, or replace server configurations using JSON or Caddyfile formats.
- Caddyfile Adaptation — Instantly convert Caddyfile text into native Caddy JSON without applying the changes.
- Upstream Monitoring — Check the real-time status and health of your proxy upstreams and backends.
- PKI & Certificates — Inspect internal CA information and retrieve certificate chains for your managed domains.
- Metrics & Observability — Access Prometheus-style metrics to monitor server performance and request traffic.
- Granular Control — Delete specific configuration paths or gracefully stop the server process.
How it works
- Subscribe to this server
- Enter your Caddy Admin API URL (e.g., http://localhost:2019)
- Start managing your reverse proxies and web servers from Claude, Cursor, or any MCP client
Who is this for?
- DevOps Engineers — automate infrastructure updates and monitor backend health without leaving the terminal or chat.
- Web Developers — quickly test and adapt Caddyfile configurations during local development.
- SREs — retrieve live metrics and PKI status to ensure site reliability and security compliance.
Built-in capabilities (13)
Adapts a configuration (e.g., Caddyfile) to JSON without running it
and target is array, expands payload array and appends elements. Sets or replaces an object; appends to an array in Caddy config
Deletes the value at the named path in Caddy config
Leave empty for full config. Exports the configuration at the specified path as JSON
Access a configuration object directly via its @id field
Exposes metrics in Prometheus exposition format
Returns information about a particular PKI app CA
Returns the certificate chain for a particular CA
Returns the current status of configured proxy upstreams
Creates a new object or inserts into an array at a specific index
Use application/json for native JSON, or text/caddyfile for Caddyfile. Sets or replaces the active Caddy configuration
Strictly replaces an existing object or array element in Caddy config
Gracefully shuts down the Caddy server and exits the process
Why Mastra AI?

Frequently asked questions
Can I use a Caddyfile instead of JSON to update my configuration?
Yes! Use the load_config tool and set the content_type to text/caddyfile. You can also use adapt_config to preview the JSON conversion before applying it.
How can I monitor the health of my load-balanced backends?
Use the get_upstreams tool. It returns the current status and health metrics of all configured proxy upstreams in your Caddy instance.
Is it possible to remove a specific site or route without resetting the whole server?
Absolutely. Use delete_config with the specific path (e.g., apps/http/servers/srv0/routes/1) to remove only that element from the active configuration.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
