More Details Connect to Claude

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

  1. Subscribe to this server
  2. Enter your Caddy Admin API URL (e.g., http://localhost:2019)
  3. 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.

delete_config

Deletes the value at the named path in Caddy config

replace_config

get_config_by_id

Access a configuration object directly via its @id field

get_metrics

Exposes metrics in Prometheus exposition format

get_pki_ca_certs

Returns the certificate chain for a particular CA

get_upstreams

Returns the current status of configured proxy upstreams

load_config

Use application/json for native JSON, or text/caddyfile for Caddyfile. Sets or replaces the active Caddy configuration

stop_server

Gracefully shuts down the Caddy server and exits the process

adapt_config

Adapts a configuration (e.g., Caddyfile) to JSON without running it

append_config

and target is array, expands payload array and appends elements. Sets or replaces an object; appends to an array in Caddy config

get_config

Leave empty for full config. Exports the configuration at the specified path as JSON

get_pki_ca

Returns information about a particular PKI app CA

insert_config

Creates a new object or inserts into an array at a specific index

Get the full JSON configuration of my Caddy server.

I've retrieved the configuration. It contains 2 HTTP servers and 4 routes. Would you like me to analyze a specific path like 'apps/http'?

Adapt this Caddyfile to JSON: 'example.com { reverse_proxy localhost:8080 }'

I've adapted the Caddyfile. The resulting JSON structure defines a server for 'example.com' with a reverse proxy handler pointing to 'localhost:8080'. Shall I apply this configuration using load_config?

Check the status of my proxy upstreams.

Fetching upstream status... I found 3 configured upstreams. All backends for 'api-cluster' are currently healthy, but one node in 'static-assets' is reporting a timeout. Would you like the full metrics?

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.
