Struct McpToolAdapter 

pub struct McpToolAdapter { /* private fields */ }

Adapter that exposes an MCP tool as an agentkit Tool.

This is the tool-layer adapter for the tool registry. For the capabilities-layer adapter, see McpInvocable. Tool names are prefixed as mcp_<server_id>_<tool_name>.

Example

use std::sync::Arc;
use agentkit_core::MetadataMap;
use agentkit_mcp::{McpToolAdapter, McpToolDescriptor, McpServerId};

Implementations

impl McpToolAdapter

pub fn new( server_id: &McpServerId, connection: Arc<McpConnection>, descriptor: McpToolDescriptor, ) -> Self

Creates a new tool adapter for the given MCP tool.

Arguments

• server_id - The server’s identifier, used to namespace the tool name.
• connection - A shared connection to the owning MCP server.
• descriptor - The tool descriptor obtained from discovery.

Trait Implementations

impl Tool for McpToolAdapter

fn spec(&self) -> &ToolSpec

Returns the static specification for this tool.

fn invoke<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, request: ToolRequest, _ctx: &'life1 mut ToolContext<'life2>, ) -> Pin<Box<dyn Future<Output = Result<ToolResult, ToolError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Executes the tool and returns a result or error.

fn current_spec(&self) -> Option<ToolSpec>

Returns the current specification for this tool, if it should be advertised right now.

fn proposed_requests( &self, _request: &ToolRequest, ) -> Result<Vec<Box<dyn PermissionRequest>>, ToolError>

Returns permission requests the executor should evaluate before calling invoke.
