turbomcp-core

Core MCP types and primitives - no_std compatible for WASM targets.

Overview

This crate provides the foundational types for the Model Context Protocol (MCP) that can be used in no_std environments including WebAssembly. It is part of the TurboMCP v3.0 architecture.

Features

std (default): Enable standard library support
rich-errors: Enable UUID-based error tracking (requires std)
wasm: Enable WASM-specific optimizations

no_std Usage

[dependencies]
turbomcp-core = { version = "3.0", default-features = false }

What's Included

Types: Core MCP types (Tool, Resource, Prompt, Content, Capabilities)
Error: Unified McpError type with JSON-RPC code mapping
JSON-RPC: JSON-RPC 2.0 request/response types

Example

use turbomcp_core::types::{Tool, ToolInputSchema};
use turbomcp_core::error::{McpError, ErrorKind, McpResult};

// Create a tool definition
let tool = Tool::new("calculator")
    .with_description("Performs calculations")
    .with_input_schema(ToolInputSchema::object());

// Handle errors
fn my_handler() -> McpResult<String> {
    Err(McpError::tool_not_found("unknown_tool"))
}
