MCP Resources (Client)

You can access the server-defined resources and resource-templates using PluMCP client API. It is assumed that you would require and alias the client namespace as follows:

[plumcp.core.api.mcp-client :as mc]

List resources and resource-templates

You can list the server-defined resources using list-resources and resource-templates using list-resource-templates:

Clojure

In Clojure (JVM) list-resources and list-resource-templates return a value.

(let [resources (mc/list-resources plumcp-client)]
  (println "Resources" resources))

(let [templates (mc/list-resource-templates plumcp-client)]
  (println "Resource templates" resource-templates))

ClojureScript

In ClojureScript list-resources and list-resource-templates return a js/Promise, so we need to chain through the value.

(-> (mc/list-resources plumcp-client)
    (.then (fn [resources]
             (println "Resources" resources))))

(-> (mc/list-resource-templates plumcp-client)
    (.then (fn [templates]
             (println "Resource templates" templates))))

Read resource

To read the resource defined in Resources (Server) by name the call would be:

Clojure

In Clojure read-resource returns a value.

(let [resource (mc/read-resource plumcp-client
                                 "text://fire/safety")]
  (println resource))

(let [resource (mc/read-resource plumcp-client
                                 "info://consumable/148")]
  (println resource))

ClojureScript

In ClojureScript read-resource returns a js/Promise.

(-> (mc/read-resource plumcp-client
                      "text://fire/safety")
    (.then (fn [resource]
             (println resource))))

(-> (mc/read-resource plumcp-client
                      "info://consumable/148")
    (.then (fn [resource]
             (println resource))))

Error handling

If an error is encountered when reading a resource, the error is printed on the screen by default. To handle the error you can specify an error handler to the call:

(mc/read-resource plumcp-client
                  "info://consumable/148"
                  {:on-error (fn [id jsonrpc-error]
                               (println "ERROR reading resource"
                                        jsonrpc-error)
                               nil)})

The :on-error option is specified to use a handler for the error. Rest is similar to result handling (CLJ vs CLJS difference remains as it is.)
