v0.2.0

Added

• A dependency-free, read-only mcp-hub-rescue CLI with status, health,
  logs, validate-config, diagnose, and doctor commands. It is installed
  outside the hub virtualenv and never imports the main server or integrations.
• Rescue isolation tests run without installing MCP Hub dependencies and verify
  that diagnostics still import when server.py is broken.

v0.1.0

First public release. Extracted from a private deployment and made
config-driven so it can run against any fleet.

Added

• 85 MCP tools over a single streamable-http endpoint, covering fleet SSH
  execution, Proxmox, Docker, Synology DSM, Cloudflare tunnels and DNS, n8n,
  Notion, a Bitwarden/Vaultwarden bridge, LM Studio, Wake-on-LAN, background
  jobs, and health probes.
• config.py, a single place resolving every site-specific value from the
  environment, .env, and YAML inventory. No address, hostname, domain, or
  credential identifier lives in the tool code.
• hosts.yaml fleet inventory with roles and tags; fleet_exec targets a
  tag rather than a hand-maintained list.
• topology.yaml (optional): curated overlay for guest mapping,
  recycled-IP traps, and a hard do-not-touch list — the knowledge a live scan
  cannot recover.
• endpoints.yaml (optional): HTTP health probes for endpoints_health,
  with a separate intermittent list for hosts that are often powered down.
• Opt-in integrations. Each is off until its *_ENABLED flag is set, and
  disabled ones return a clear error rather than failing obscurely.
• Pluggable secrets provider: env (default) or vaultwarden via a
  bw serve daemon. DSM and Notion credentials resolve through either.
• Bearer-token authentication (MCP_AUTH_TOKEN), enforced by ASGI
  middleware with a constant-time comparison.
• Multiplexed SSH with a configurable ControlPath, so fleet-wide commands
  reuse one connection per host.
• Packaging: pyproject.toml with a mcp-hub entry point, pinned
  requirements.txt, systemd unit templates, and an idempotent
  deploy/install.sh that provisions a dedicated user, a dedicated SSH key,
  and generated secrets without ever overwriting existing config.
• --version / -V flag, and a version field in mcp_health.
• CI: lint, an import-and-register smoke test across Python 3.11–3.13, a
  read-only enforcement test, and a guard rejecting private network data or a
  tracked real config file.

Security

• MCP_READ_ONLY defaults to true. All 37 mutating tools refuse until
  it is explicitly turned off. Enforcement is centralised by wrapping tool
  registration, so a tool cannot silently escape the guard — but a new
  mutating tool must be added to config.MUTATING_TOOLS, which CI checks.
• Binds 127.0.0.1 by default instead of 0.0.0.0. Exposing remote shell
  execution on a network is now a deliberate act.
• SECURITY.md states the threat model without softening it: this is
  remote code execution as a service, and prompt injection is an RCE primitive
  against it. It also lists what the project explicitly does not defend
  against.
• The MCP initialize handshake now reports the hub's own version. Previously
  it fell back to the installed mcp library version, misinforming clients.
• Secret redaction is applied to file reads and command output.

Known limitations

• Docstrings are a mix of French and English; the project began as a private
  French-language tool.
• server.py is a ~3600-line monolith. Splitting it into tools/* modules is
  planned, in reviewable behaviour-preserving chunks.
• ruff format and the UP lint rules are not enforced yet — applying either
  wholesale would bury every subsequent diff.
• There is one trust level. Anyone holding the bearer token has full access;
  there is no per-tool ACL and no multi-user model.
