drpcli mcp serve¶
Run a Model Context Protocol server over stdio
Synopsis¶
Run an MCP (Model Context Protocol) server over stdin/stdout that exposes the drpcli command surface as MCP tools, suitable for embedding in MCP-aware clients such as Claude Desktop or Claude Code.
The server inherits authentication from the surrounding drpcli flags and environment variables (RS_ENDPOINT, RS_KEY, etc.). Each MCP tool call runs the corresponding drpcli command in-process and returns its JSON output.
Use --read-only to expose only commands that read state. Mutating commands (create, update, destroy, params set, generate repo, ...) are then filtered out of the published tool list entirely.
Examples¶
Text Only
# Start with default credentials from environment
drpcli mcp serve
# Read-only mode (no mutations)
drpcli mcp serve --read-only
# Connect to a specific endpoint
drpcli mcp serve -E https://drp.example.com:8092 -U admin
# Serve docs from the stable tree instead of dev
drpcli mcp serve --docs-version stable
# Serve docs from a local zip (airgapped / pinned snapshot)
drpcli mcp serve --local-docs drp-docs.zip
# Disable the documentation tools
drpcli mcp serve --no-docs
Options¶
Text Only
--docs-url string Base URL of the docs site for remote docs (default "https://docs.rackn.io")
--docs-version string DRP docs tree version to serve over the docs tools (e.g. dev, stable, v4.17) (default "dev")
-h, --help help for serve
--local-docs string Path to a local docs archive (zip, .tgz, or rofs tar/iso/squashfs; a top-level llms.txt plus an md/ tree); overrides remote docs
--no-docs Disable the DRP documentation tools (docs_search/docs_fetch)
--output-format string Output format MCP tools return for every call (json or yaml) (default "json")
--read-only Only expose tools that read state; mutating commands are not registered
Options inherited from parent commands¶

-c, --catalog string The catalog file to use to get product information (default "https://repo.rackn.io")
--catalog-path string The path to where the catalog file exists on the drp server. By default and historically this has been /files/rebar-catalog. For example, if no catalog urls are provided, the complete path will be https://drp-ip:8090/files/rebar-catalog (default "/files/rebar-catalog")
-S, --catalog-source string A location from which catalog items can be downloaded. For example, in airgapped mode it would be the local catalog
--client-cert string Client certificate to use for communicating to the server - replaces RS_KEY, RS_TOKEN, RS_USERNAME, RS_PASSWORD
--client-key string Client key to use for communicating to the server - replaces RS_KEY, RS_TOKEN, RS_USERNAME, RS_PASSWORD
-C, --colors string The colors for JSON and Table/Text colorization. 8 values in the for 0=val,val;1=val,val2... (default "0=32;1=33;2=36;3=90;4=34,1;5=35;6=95;7=32;8=92")
-d, --debug Whether the CLI should run in debug mode
-D, --download-proxy string HTTP Proxy to use for downloading catalog and content
-E, --endpoint string The Digital Rebar Provision API endpoint to talk to (default "https://127.0.0.1:8092")
-X, --exit-early Cause drpcli to exit if a command results in an object that has errors
--fetch-catalogs all Determines which catalog urls to use to fetch the catalog. If set to all, all the catalog urls defined with catalog_url and catalog_urls as well as the default catalog will be used. If set to server, only the catalog urls defined on the server will be used. If set to cli, then the specific url specified with the -c flag will be used. It defaults to `all`. Allowed values `all, `server`, `cli`. (default "all")
-f, --force When needed, attempt to force the operation - used on some update/patch calls
--force-new-session Should the client always create a new session
-F, --format string The serialization we expect for output. Can be "json" or "yaml" or "text" or "table" (default "json")
--http-request-retry-count int Specifies the number of retries for downloads in case of failure
--http-request-retry-delay-max int Specifies the maximum delay (in seconds) between HTTP/HTTPS retry attempts (default 60)
--ignore-unix-proxy Should the client ignore unix proxies
-N, --no-color Whether the CLI should output colorized strings
-H, --no-header Should header be shown in "text" or "table" mode
-x, --no-token Do not use token auth or token cache
-P, --password string password of the Digital Rebar Provision user (default "r0cketsk8ts")
-p, --platform string Platform to filter details by. Defaults to current system. Format: arch/os
-J, --print-fields string The fields of the object to display in "text" or "table" mode. Comma separated

-G, --show-global-help-flags Show global flags in help message
-T, --token string token of the Digital Rebar Provision access
-t, --trace string The log level API requests should be logged at on the server side
-Z, --trace-token string A token that individual traced requests should report in the server logs
-j, --truncate-length int Truncate columns at this length (default 40)
