v0.2.0 — server-hosted MCP Latest
Latest

The MCP moved server-side. The loopback MCP is no longer a client-side stdio bundle installed onto each machine — it is now hosted by the loopback service as a remote MCP, so MCP behaviour updates ship with the service and no client re-install is needed.

npx @guidobuilds/loopback-setup [agent] --service-url <your-service> --token <token>

Added

  • Server-hosted MCP (service/app/mcp_server.py): FastAPI mounts a Streamable-HTTP MCP at /mcp with static Authorization: Bearer auth against the existing per-user tokens table. POST /feedback and the MCP submit_feedback tool share one ingest core (service/app/ingest.py).

Changed

  • Installer registers a remote endpoint instead of a bundle — {type:"http"|"remote", url:"<service>/mcp", headers:{Authorization:"Bearer …"}} per harness; no server.bundle.js is downloaded.
  • Redaction is done by the detector skill in-context; the service re-checks and quarantines leaks, returning the patterns for a one-shot re-redact + retry.
  • Detector skill self-detects at every turn boundary with no hook/tripwire dependency.

Removed

  • The client-side loopback/mcp + loopback/core packages and the shipped bundle. loopback is now just the feedback-detector skill + /harness-feedback command.
  • Tools redact_preview, is_muted, mute_artifact, get_session_state, record_signal (the surface is a single submit_feedback), and per-machine muting.

Breaking

  • Existing 0.1.x (stdio-bundle) installs must re-run the installer. The self-hosted service must run 0.2.0+ (it hosts the MCP endpoint).

v0.1.0 — @guidobuilds/loopback-setup

First public release of loopback on npm.

Install: npx @guidobuilds/loopback-setup [agent] (agents: claude-code | opencode | codex)

Highlights

  • Ephemeral installer published as @guidobuilds/loopback-setup — wires the loopback MCP server, the feedback-detector skill, and the /harness-feedback command into your agent. No persistent CLI is left behind.
  • Replaces the old persistent CLI; no hooks, no background turn-state.
  • Wire contract: the client no longer generates a record id; the service assigns the canonical fb_<uuid> on ingest and echoes it back.

Notes

  • Requires Node.js ≥ 18.
  • Deploy the matching service/ (it assigns ids server-side) before the new client submits feedback.

Full notes in CHANGELOG.md.
