RUNTIMEWIRE INVESTIGATION — Original analysis

Original reporting by RuntimeWire, based on reverse engineering.

なぜ重要なのか

企業はモデルエンドポイントの先まで制御を押し進めている。顧客が運用するセッションホストは、従業員のインターフェースとしてDesktopを維持しつつ、Claude Codeの実行、ポリシー、および監査を集中管理するだろう。

Finding

Claude Desktop 2.2553.1 contains an internal, unreleased configuration that can redirect Code session traffic to an organization-specified HTTPS session host while supporting corporate authentication and a restricted bridge to local files.

How we verified

Methods: reverse engineering.

RuntimeWire's static analysis of the packaged Claude Desktop 2.2553.1 source found the “Self-hosted execution” configuration, routing for Code session and environment-provider APIs, authentication plumbing, and a device-file WebSocket bridge.

RuntimeWire statically analyzed the packaged application and compared the September 18 build with a September 10 comparison package; it did not alter the internal-build gate, execute the hidden functionality, authenticate to private services, or contact the placeholder endpoint.

Tested versions:

  • Claude Desktop 2.2553.1

Company response

RuntimeWire requested comment; the company had not responded by publication time.

A desktop computer's screen shows a luminous data connection leading to remote server racks, with a smaller link returning to a local file folder.

Claude Desktop 2.2553.1 contains an internal configuration that can redirect the Code tab's session traffic to an organization-specified HTTPS server, according to RuntimeWire's static analysis of the app's packaged source.

Three days before that build, Coder announced Claude Code support for Agent Relay, an early-access integration that also places tool execution inside customer-controlled workspaces. Coder said it developed the integration with support from the Claude Code team and was working with selected design partners.…
