Added

• MCP tool filtering: New mcp.include_tools and mcp.exclude_tools options in config.yaml to control which tools are exposed to MCP clients.

Usage

# .mie/config.yaml
mcp:
  # Option A: whitelist — only expose these tools
  include_tools:
    - mie_analyze
    - mie_store
    - mie_query

  # Option B: blacklist — expose all except these
  exclude_tools:
    - mie_export
    - mie_repair

• include_tools takes precedence when both are set
• Filtered tools are hidden from tools/list and rejected on tools/call
• Fully backward compatible — omitting the mcp section exposes all tools as before

Fixed

• Fork bomb in daemon start: forkDaemonBackground and connectOrStartDaemon spawned mie daemon start without --foreground, so each child re-forked indefinitely (~1 fork/500ms). The forked child now runs with --foreground to enter the actual daemon serve loop.

Full Changelog: v1.3.5...v1.3.6

Fixed

• Daemon child processes left as zombies: runDaemonStart and connectOrStartDaemon now call cmd.Wait() in a background goroutine after cmd.Start() to reap the forked daemon process
• Zombie accumulation when daemon runs as PID 1 in a container without tini: a SIGCHLD handler with Wait4(WNOHANG) now reaps orphaned child processes automatically

Full Changelog: v1.3.4...v1.3.5

Fixed

• --foreground flag ignored in mie daemon start --foreground: the parent runDaemon FlagSet had UnknownFlags = true which silently consumed --foreground before it reached runDaemonStart — the daemon would fork into background mode and exit immediately, causing systemd services to fail with a restart loop

Full Changelog: v1.3.1...v1.3.2

Added

• Auto-start daemon on mie init: the daemon is started after config creation (and interview if used), so the MCP server is immediately ready when the IDE connects

Highlights

MIE now supports multiple concurrent MCP clients (Claude, Cursor, etc.) without "database locked" errors. A single daemon process holds the exclusive RocksDB lock and multiplexes access over a Unix domain socket.

How it works

mie --mcp  →  auto-starts daemon if not running  →  connects via socket

No configuration needed — it just works. You can also manage the daemon manually:

mie daemon start              # foreground
mie daemon start --background # detached
mie daemon stop
mie daemon status

What's New

Added

• Daemon server serving CozoDB over Unix domain socket
• SocketBackend client forwarding queries to daemon via newline-delimited JSON
• mie daemon start|stop|status CLI commands
• Auto-start daemon from mie --mcp with retry/backoff
• MetaBackend interface for transparent local/remote storage
• NewClientWithBackend constructor for daemon-connected clients
• Ping-based liveness detection for stale socket cleanup
• PID file locking with flock() to prevent concurrent starts
• Socket permissions restricted to owner-only (0600)
• Embedding dimension validation (daemon ↔ client)
• 15 new tests (13 socket/daemon + 2 dimension validation)

Fixed

• Deadlock in SocketBackend.Close() — mutex released before closing connection
• Silent fallback to embedded mode — now fails with clear error instead
• PID file race condition — atomic flock() instead of write-then-check
• Stale socket from crashed daemon — ping + cleanup on connect
• Scanner errors in daemon now logged
• Context propagation in daemon dispatch
• Protocol response ID validation
• Clean disconnect via MethodClose on close

Changed

• mie --mcp requires daemon (auto-started or manual) instead of opening CozoDB directly
• Graceful shutdown waits up to 5s for active handlers

What's New

Added

• mie_repair tool: rebuilds HNSW indexes and cleans orphaned embeddings when semantic search encounters corruption
• Embedding backfill: BackfillEmbeddings generates vectors for nodes created before embeddings were enabled
• Semantic search result boosting: content containing the query text gets its distance halved
• Semantic search quality filter: results with cosine distance > 0.6 (< 40% similarity) are excluded
• Field length validation: content (50,000 chars), titles (500), descriptions (2,000), names (200)
• mie_bulk_store pre-validation: validates all items (required fields, enums, JSON arrays, date formats) before storing any, ensuring atomic-or-nothing behavior
• Entity upsert detection: mie_store now shows "Stored new entity" vs "Updated existing entity"
• topic added to MCP schema node_types enum across all tools
• Fact invalidation without replacement: replacement_id is now optional in mie_update; omitting it marks the fact invalid without creating a replacement chain
• Edge existence check: mie_delete remove_relationship now verifies the edge exists before attempting removal
• Invalidation target pre-validation: mie_store with invalidates verifies the target fact exists before storing the new fact
• JSON validation for alternatives field in decisions (rejects non-JSON-array values)
• Warning for empty role on decision_entity edges
• Embedding coverage stats per node type in mie_status (e.g., "Facts: 47/49")
• Decision status breakdown in mie_status (e.g., "9 active, 1 superseded")
• Orphaned edge cleanup during node deletion

Fixed

• Datalog export syntax (HIGH): now generates valid CozoDB :put format with proper key/value separation — previously produced unparseable output
• mie_analyze conflict display: shows the existing fact (with ID) instead of the empty proposed fact
• mie_query filter pass-through: category/kind filters no longer exclude Decision and Event types that don't have those fields
• Embedding deletion: errors in DeleteNode now log warnings instead of being silently swallowed, preventing orphaned HNSW entries
• Async embedding timeout: embedding generation now uses a 30-second timeout instead of unbounded context.Background()
• mie_export embeddings message: only shown when actual embedding count > 0
• MockEmbeddingProvider: uses word-level hashing so texts sharing words produce similar vectors, fixing TestIntegrationSemanticSearch

Changed

• Edge schema refactored to support explicit key/value column separation for CozoDB :put syntax
• Sorting and filtering logic improved in list and query operations with better error handling
• CI workflow updated to golangci-lint-action v7
• MCP server version bumped to 1.2.0
