Struct McpCapabilityProvider 

pub struct McpCapabilityProvider { /* private fields */ }

A CapabilityProvider that surfaces MCP tools, resources, and prompts into the agentkit capabilities system.

Built from a discovery snapshot, this provider wraps each MCP tool as an McpInvocable, each resource as an McpResourceHandle, and each prompt as an McpPromptHandle.

Example

use std::sync::Arc;
use agentkit_mcp::{McpCapabilityProvider, McpServerConfig, McpTransportBinding, StdioTransportConfig};

let config = McpServerConfig::new(
    "filesystem",
    McpTransportBinding::Stdio(StdioTransportConfig::new("npx")
        .with_arg("-y")
        .with_arg("@modelcontextprotocol/server-filesystem")),
);
let (connection, provider, snapshot) = McpCapabilityProvider::connect(&config).await?;
// `provider` implements CapabilityProvider and can be registered with an agent.

Implementations

impl McpCapabilityProvider

pub fn from_snapshot( connection: Arc<McpConnection>, snapshot: &McpDiscoverySnapshot, ) -> Self

Creates a capability provider from an existing connection and its discovery snapshot.

Each tool, resource, and prompt in the snapshot is wrapped in the appropriate adapter type.

pub fn merge<I>(providers: I) -> Self

where I: IntoIterator<Item = Self>,

Merges multiple capability providers into a single provider.

This is useful when managing several MCP servers through a McpServerManager and you want one combined provider for the agent.

pub async fn connect( config: &McpServerConfig, ) -> Result<(Arc<McpConnection>, Self, McpDiscoverySnapshot), McpError>

Connects to an MCP server, performs discovery, and builds a capability provider in one step.

Returns the shared connection, the provider, and the discovery snapshot.

Errors

Returns McpError if connection or discovery fails.
