Hey team! sorry for the 100 questions :grin:! but ...

# koog-agentic-framework

Hey team! sorry for the 100 questions 😁! but im working on a Koog agent and MCP server... i added this dependencies in the commonMain:

implementation(libs.koog.agents)
implementation(libs.mcp)
mcp = { module = "io.modelcontextprotocol:kotlin-sdk", version.ref = "mcp" }
and
koog-agents = { module = "ai.koog:koog-agents", version.ref = "koog" }
with this version:
koog = "0.3.0"
mcp = "0.6.0"

but when i tried to add the mcp tool to my agent like this:

// Start the MCP server (e.g., as a process)
val process = ProcessBuilder("path/to/mcp/server").start()

// Create a ToolRegistry with tools from the MCP server
val toolRegistry = McpToolRegistryProvider.fromTransport(
    transport = McpToolRegistryProvider.defaultStdioTransport(process)
)

// Use the tools in an AI agent
val agent = AIAgent(
    promptExecutor = executor,
    strategy = strategy,
    agentConfig = agentConfig,
    toolRegistry = toolRegistry
)

// Run the agent
agent.run("Your task here")

my Android Studio can't find these classes McpToolRegistryProvider, McpTool and McpToolRegistryProvider

Hi Eduardo!
Could you please share the imports in the file where you define the agent?
Also, just an assumption, but did you sync Gradle changes agter adding the dependencies?

[Eduardo Ruesta]

Hey Anastasiia! sure let me send you that and yes i suync gradle changes

[Eduardo Ruesta]

more information, i have another koog project but only Android, that works fine the import but for this project that is KMM for Android and WasmJS where i define the dependency inside of the

commonMain.dependencies {

is not

[Eduardo Ruesta]

for kmm project, do we need another import like this:

koog-mcp = { module = "ai.koog:koog-agents-mcp", version.ref ="koog" }

or with this one is okay:

koog-agents = { module = "ai.koog:koog-agents", version.ref = "koog" }

[Pavel Gorgulov]

koog-mcp is currently jvm only. Try adding it directly like this:

koog-mcp = { module = "ai.koog:agents-mcp-jvm", version.ref = "koog" }

Also note that koog 0.3.0 is using mcp client version 0.5.0. There were breaking changes introduced in version 0.6.0, so compatibility between client and server of different versions is not guaranteed

[Eduardo Ruesta]

cool! let me try it! thanks Pavel

[Eduardo Ruesta]

so, for example the McpToolRegistryProvider inside the commonMain is not working?

[Pavel Gorgulov]

Unfortunately, no(
There is in jvmMain
https://github.com/JetBrains/koog/blob/develop/agents/agents-mcp/src/jvmMain/kotlin/ai/koog/agents/mcp/McpToolRegistryProvider.kt

But with the new version of mcp 0.6.0, we’ll be able to add this to common in the upcoming releases

[Eduardo Ruesta]

gotcha!! thanks for this information
