Functions

func New

func New(cfg Config) (tool.Toolset, error)

New returns MCP ToolSet. MCP ToolSet connects to a MCP Server, retrieves MCP Tools into ADK Tools and passes them to the LLM. It uses https://github.com/modelcontextprotocol/go-sdk for MCP communication. MCP session is created lazily on the first request to LLM.

Usage: create MCP ToolSet with mcptoolset.New() and provide it to the LLMAgent in the llmagent.Config.

Example:

llmagent.New(llmagent.Config{
	Name:        "agent_name",
	Model:       model,
	Description: "...",
	Instruction: "...",
	Toolsets: []tool.Set{
		mcptoolset.New(mcptoolset.Config{
			Transport: &mcp.CommandTransport{Command: exec.Command("myserver")}
		}),
	},
})

Types

type Config

type Config struct {
	// Transport that will be used to connect to MCP server.
	Transport mcp.Transport
	// ToolFilter selects tools for which tool.Predicate returns true.
	// If ToolFilter is nil, then all tools are returned.
	// tool.StringPredicate can be convenient if there's a known fixed list of tool names.
	ToolFilter tool.Predicate
}

Config provides initial configuration for the MCP ToolSet.
