Network glossary

Map Local

A traffic override rule that intercepts a matched request and immediately serves a local file, mock JSON draft, or directory from the host machine rather than forwarding the request to the real internet.

Map Remote

A rule that rewrites the destination hostname, port, protocol, path, or query parameters of a request, forwarding it to a different remote server.

Effect Bundle (.jproxy-effects)

A portable scenario containing coordinated rules and assets. Review before activation; preparing or saving an inactive bundle does not change live traffic.

HLS Fixture Server

An in-process HTTP media server embedded inside JoesProxy that generates synthetic HTTP Live Streaming (HLS) playlists and video segments with controllable defect profiles (missing codecs, timestamp discontinuities, key rotation).

Model Context Protocol (MCP)

An open protocol allowing AI coding assistants and autonomous agents to query contextual data and invoke tools in local developer applications under explicit human supervision.

Inspection Reason and Body Availability

Inspection Reason explains whether HTTPS was inspected or tunneled. Body availability separately describes retained, pending, deferred, omitted or truncated evidence. Neither a size nor a status code proves that the complete body is available.

Delivery Evidence

Proxy-side observations of transport and queued writes. Completed writes do not prove target rendering or playback. Unavailable evidence remains unknown.

Try it

If a capture shows only a tunnel, start with routing and inspection. If it shows a status but no body, check what the capture retained before changing trust settings.
