v0.2.5

Added

• Gate StdioTransport behind default-on stdio feature (#30)

v0.2.4

Added

• Gate StdioTransport behind default-on stdio feature (#30)

v0.2.3

Added

• Add structured tracing spans around MCP lifecycle operations without adding
  a rig-tap dependency. Loopback and stdio list/call paths plus stdio spawn
  and server dispatch now emit spans with mcp.transport, mcp.endpoint,
  mcp.tool_name, mcp.tool_count, mcp.program, mcp.arg_count, and
  mcp.error fields where applicable.

v0.2.2

Added

• Add cached result transport tools

Added

• Add CachedResultsTransport, CachedResultsConfig, and cache page/release
  tools for opt-in model-boundary caching of oversized MCP array results.

v0.2.1

Added

• Align replay snapshots with compose descriptors

Changed

• Require rig-compose 0.4.1 and use ToolRegistry::descriptors() for
  loopback discovery and registry-backed registration snapshots.

v0.2.0

Added

• Add cached result metadata and replay snapshots

Added

• Extend CachedResultEnvelope with truncated, omitted_items, and
  page_token metadata so MCP cached array previews align with
  rig-compose result-envelope semantics while preserving page handles.
• Add RegistrationSnapshot and RegistrationReplayPolicy for deterministic,
  adapter-local replay of discovered MCP tool registrations after reconnects.

v0.1.5

Added

• Add result cache primitives

Fixed

• Make harness example self-contained

Added

• result_cache module: transport-neutral cache for paged large tool
  results. Public surface: ResultCache trait, MemoryResultCache
  in-memory impl, CachedResultHandle / CachedResultEnvelope JSON
  types, and a cache_if_large helper that envelopes oversized arrays
  with a handle, total item count, page size, and a deterministic first
  page. Wires the foundation for the page/search/release follow-up tools
  called out in ROADMAP "Next Work" item 1; transport-level integration
  remains a separate downstream change.

v0.1.4

Added

• Enhance stdio transport with weather lookup tool and result bounding tests
• (stdio) Add stdio bin + stdio_failures integration tests (#6)
• Add deterministic MCP loopback harness prototype and update documentation

Documentation

• Normalize quick start section
• Rename coordination references to rig-ecosystem
• Align ecosystem docs with rig-compose 0.3, rig-core 0.37, and rig-model-meta 0.1 (#11)
• Update ecosystem topology with rig-compose 0.3 and rig-model-meta (#10)
• Update ecosystem topology with rig-compose 0.3 and rig-model-meta (#9)
• Update ecosystem topology with rig-compose 0.3 and rig-model-meta (#8)
• Add mcp roadmap

Added

• Add crate-local ROADMAP.md documenting maturity status, next work, and
  non-goals for the MCP bridge.
• Add tests/harness.rs, a deterministic MCP loopback harness prototype that
  records task input, endpoint, discovered tool names, normalized invocation,
  MCP-adapted dispatch result, final answer, and passed assertions.
• Add deterministic stdio fixtures covering successful child-process calls,
  unknown tools, missing arguments, wrong argument types, malformed child
  output, and child exit before handshake.
• Add stdio result-envelope coverage for oversized MCP outputs. The test proves
  StdioTransport preserves raw structured output and callers can use
  rig_compose::bound_tool_result for deterministic truncation metadata.
• Extend the deterministic harness to exercise the same tool task through local
  ToolRegistry, LoopbackTransport, and real child-process StdioTransport
  paths.

Deprecated

• McpTool::new is deprecated in favour of [McpTool::from_transport],
  which is the only constructor exercised by callers. The associated
  function will be removed in the next major release.

v0.1.3

Documentation

• Remove retired repo references

v0.1.2

Fixed

• Depend on released rig-compose
• Remove stdio transport mutex

Fixed

• StdioTransport now stores the rmcp peer handle directly and drops
  its tokio::sync::Mutex, eliminating cross-await lock contention and
  letting concurrent tools/list / tools/call RPCs proceed in parallel.
