What's New in v1.0.0

v1.0.0 is the first stable release of rust-mcp-sdk.

Highlights

• First stable release - all crates at v1.0.0 together
• 100% MCP conformance - passes all server and client conformance tests
• Handler traits remain open (unsealed) - you can implement them for your own types

Public API Renames

Three typos were fixed in the public API. These are breaking renames - the old names were removed, so update your call sites:

Old Name	New Name
PingParamaters	PingParameters
Implementation.capabilites	Implementation.capabilities
ElicitResult	(corrected serialization)

Dead Code Removal

• Removed unused types from rust-mcp-schema
• Removed server_driver.rs from rust-mcp-sdk
• Removed shutdown functionality from ClientRuntime
• Removed json-with-source response type (never supported by any MCP implementation)

Deprecation Hygiene

All items deprecated in v0.9.x and v0.10.x have been removed.

CI Hardening

• Rust 1.86 clippy compliance
• MSRV bumped to 1.80
• mcp-discovery and rust-mcp-filesystem pinned to rust-mcp-sdk = "1.0"
