McpToolRegistryProvider

A provider for creating tool registries that connect to Model Context Protocol (MCP) servers.

This class facilitates the integration of MCP tools into the agent framework by:

Connecting to MCP servers through various transport mechanisms (Streamable HTTP, stdio, SSE)
Retrieving available tools from the MCP server
Transforming MCP tools into the agent framework's Tool interface
Registering the transformed tools in a ToolRegistry

Types

Configuration for connecting to an MCP server over the Streamable HTTP transport.

Default name for the MCP client when connecting to an MCP server.

Default version for the MCP client when connecting to an MCP server.

Creates a default server-sent events (SSE) transport from a provided URL.

Creates a default standard input/output transport for a provided process.

suspend fun fromClient(mcpClient: Client, serverInfo: McpServerInfo, mcpToolParser: McpToolDescriptorParser = DefaultMcpToolDescriptorParser): ToolRegistry

Creates a ToolRegistry with tools from an existing MCP client.

suspend fun McpToolRegistryProvider.fromProcess(process: Process, clientInfo: Implementation = Implementation(DEFAULT_MCP_CLIENT_NAME, DEFAULT_MCP_CLIENT_VERSION), mcpToolParser: McpToolDescriptorParser = DefaultMcpToolDescriptorParser): ToolRegistry

Creates a Mcp ToolRegistry instance from a process using default standard input/output transport.

suspend fun fromSseUrl(sseUrl: String, clientInfo: Implementation = Implementation(DEFAULT_MCP_CLIENT_NAME, DEFAULT_MCP_CLIENT_VERSION), mcpToolParser: McpToolDescriptorParser = DefaultMcpToolDescriptorParser): ToolRegistry

Creates a ToolRegistry with tools from an MCP server using a server-sent events (SSE) transport.

suspend fun fromTransport(transport: Transport, serverInfo: McpServerInfo, mcpToolParser: McpToolDescriptorParser = DefaultMcpToolDescriptorParser, name: String = DEFAULT_MCP_CLIENT_NAME, version: String = DEFAULT_MCP_CLIENT_VERSION): ToolRegistry

Creates a ToolRegistry with tools from an MCP server using provided transport for communication.

Creates a ToolRegistry from a Streamable HTTP MCP server.
