v1.3.0

Bug Fix Release — 19 bugs resolved

Critical

• gRPC adapter used input descriptor for response deserialization — all gRPC calls returned wrong/empty results

High (7)

• Prompt handler called under RLock — deadlock risk
• OpenAPI query params not URL-encoded; body fields always sent as strings
• Self-referential structs caused infinite recursion in schema generator
• []Struct slices generated wrong item schema
• SetMaxConcurrentTasks orphaned in-flight tasks
• AsyncToolFunc corrupted existing sync tools with matching base name

Medium (10)

• notifyFn data race between notify() and Handler()
• Completed async tasks never evicted (memory leak)
• HTTP transport silently truncated oversized bodies
• stdio transport append could mutate handler's returned slice
• mcptest.Client panicked on nil returns / missing map keys
• ToolFunc didn't validate function signature types
• Handler returning (nil, nil) produced protocol-violating null result
• watchDir goroutine leaked on shutdown
• Deleted YAML files left zombie tools registered
• provider.go HTTP client had no timeout

Low (1)

• Multiple Handler() calls overwrote notification function
