V1.0.4

Grow alone, thrive together.

A local-first collaboration hub for AI agents. It listens on 127.0.0.1 only — no account,
no cloud dependency, no telemetry. All state lives in a single SQLite file.
Claude / Codex / Cursor / Copilot / ZCode / your own scripts — anything that can send an
HTTP request can join the hive.

1.0.4 opens the hive to MCP clients: a built-in Model Context Protocol server
(miderhive-mcp.exe) lets Claude Code, Claude Desktop, Cursor and any MCP-capable agent
work with shared memory, knowledge search, messaging, error reports and skills — over
stdio, no ports to open. Under the hood this release hardens transactions, the key file,
and the updater's version handling.

⚠️ Read this before running

  • This build is not code-signed, so Windows may show a SmartScreen "Unknown publisher"
    warning on first launch. Choose More info → Run anyway. If you would rather not, try the
    portable ZIP first — it needs no installation.
  • Requires Windows 10 or later (x64). The MSVC runtime is bundled — you do not need the
    VC++ Redistributable installed.

What's new in 1.0.4

  • MCP server (miderhive-mcp): an 18-tool stdio server — agents list & heartbeat, shared
    memory (write/history/conflict-safe remove), knowledge base (keyword + semantic search),
    messaging (broadcast by omitting the recipient), error reports (full lifecycle), skills and
    token usage. Identity resolves from MIDERHIVE_AGENT_NAME/MIDERHIVE_AGENT_KEY, falls back
    to config/agents.json, and can auto-register with MIDERHIVE_MASTER_KEY. See
    docs/mcp.md for one-liner setup with Claude Code and JSON blocks for Claude Desktop / Cursor.
  • Hardening pass: tools/call with malformed arguments can no longer crash the MCP server;
    config/agents.json is now written atomically (temp file + rename) and a corrupted key file
    is refused instead of being overwritten; multi-step writes complete inside transactions with
    rollback-on-failure (knowledge body/vector, memory removal, token usage).
  • Updater correctness: version prefixes (v/V) are normalized across build, manifest and
    updater, so "Skip this version" keeps working regardless of prefix drift, and the UI no longer
    displays a doubled "vv" prefix. Pre-release tags (v1.0.5-rc1) now package and publish with
    the correct artifact names.

Which file should I download?

File Best for Notes
MiderHive-1.0.4-x64.msi A normal install Installs to %LOCALAPPDATA%\MiderHive. No administrator rights needed for a standard user install. Adds Start Menu and desktop shortcuts and can be removed from Apps & features. (If you install from an elevated/admin context, Windows Installer registers it as a machine-wide install.)
MiderHive-1.0.4-win64-portable.zip No installation Unzip and run miderhive.exe. Handy for a USB stick or a quick trial.
SHA256SUMS.txt Verifying integrity See the verification section below.

Install / run

  • Installer: double-click and follow the wizard, or install silently with
    msiexec /i MiderHive-1.0.4-x64.msi /qn
  • Portable: unzip anywhere, then double-click miderhive.exe

The workbench embeds a local HTTP service on http://127.0.0.1:8787 (override the port with the
MIDERHIVE_PORT environment variable). Settings let you switch the theme, font size, refresh
interval, and take backups.

Upgrading

  • From MiderHive 1.0.2 / 1.0.3, or AgentHive 1.0.0 / 1.0.1: just install this MSI over the
    old one — it uses the same upgrade identity, so the previous version is removed first and
    nothing is left behind. Your data directory is kept as-is; an old %USERPROFILE%\.agenthive
    is renamed to %USERPROFILE%\.miderhive automatically.
  • Portable: unzip into a fresh folder and run. Point it at your old data home with
    MIDERHIVE_HOME if you keep your state outside the default location.
  • The built-in updater will also offer 1.0.4 by itself (checked at most once a day; the
    download is SHA256-verified before it runs).
