Mira, short-term memory for autonomous systems
An OTLP-native telemetry storage engine that turns logs, traces, and metrics into immutable Apache Arrow IPC blocks readable through a UI, terminal, or MCP.
Field notes
Mira accepts OpenTelemetry data over gRPC or HTTP and stores it as immutable Apache Arrow IPC blocks. Its documented access paths include a browser UI, terminal commands, an HTTP API, and MCP, with example endpoints on ports 4317 and 4318. The homepage reports 1,458,967 records per second on 1.78 cores and describes a 5.62 MiB binary containing three signals, two interfaces, and MCP access. Its comparison table explicitly warns that competing figures use different conditions.
