## Thinking Path > - Paperclip is the open source control plane people use to manage AI agents for work > - Local coding adapters can be confined with filesystem and network sandbox policies > - Codex confinement proxied only user-allowlisted hosts, so it denied Paperclip's own run API and managed MCP endpoints > - The same proxy returned untyped plaintext denials, which MCP clients could treat as a fatal unexpected content type > - Host-only `PAPERCLIPAI_CMD` values could also leak into agents even when the referenced checkout module did not exist > - This pull request gives the sandbox an explicit trusted-URL channel for Paperclip endpoints, returns structured JSON errors, and removes the inherited host CLI pointer > - The benefit is confined Codex agents retain control-plane access without broadening the operator's external network allowlist or crashing on policy denials ## Linked Issues or Issue Description Refs #3802 Related foundation: #9504 ### What happened? A `codex_local` agent configured with `networkScope: "allowlist"` and an external-only allowlist could not reach its own Paperclip API or Paperclip-managed MCP endpoints. The sandbox proxy returned a `403` plaintext response without `Content-Type`, and an inherited `PAPERCLIPAI_CMD` could point at a missing checkout-local CLI module. ### Expected behavior Paperclip's run-scoped API and managed MCP endpoints remain reachable regardless of the user external allowlist. Policy denials are valid structured JSON responses with an explicit media type, and host-only CLI pointers are not inherited by agent processes. ### Steps to reproduce 1. Configure a `codex_local` agent with `networkScope: "allowlist"` and `networkAllowlist: ["api.openai.com"]`. 2. Run the agent and request its Paperclip issue API or a Paperclip-managed MCP endpoint. 3. Observe the sandbox proxy deny the request with an untyped plaintext `403` response. ### Environment - Paperclip commit: `f49a3f99` originally exhibited the defect; fix is based on current `master`. - Deployment: local source build on Linux. - Adapter: Codex. - Database: not database-related. - Access context: agent bearer/run-scoped credentials. ## What Changed - Added internal trusted URL rules to the local network allowlist proxy and supplied the Codex run API plus managed MCP endpoints. - Returned JSON error envelopes with `Content-Type` and `Content-Length` for HTTP and CONNECT policy denials. - Removed inherited `PAPERCLIPAI_CMD` from child process environments while preserving explicitly constructed runtime variables. - Added focused proxy and environment sanitizer regression tests. ## Verification - `pnpm exec vitest run packages/adapter-utils/src/local-process-sandbox.test.ts packages/adapter-utils/src/server-utils-env.test.ts --reporter=verbose` - 2 test files passed; 8 tests passed; 4 platform-dependent tests skipped. - `git diff --check` - Package typecheck was attempted; it reaches unrelated current-`master` type drift in untouched files (`spawnCwd` in `adapter-utils`, and staged-runtime ACP types in `codex-local`). ## Risks - Low risk: trusted access is restricted to exact HTTP(S) hostname and port pairs derived from Paperclip-provided URLs. - Invalid or non-HTTP trusted URL values are ignored rather than broadening access. - Denial response bodies change from plaintext to structured JSON; status codes remain unchanged. > For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and discuss it in `#dev` before opening the PR. Feature PRs that overlap with planned core work may need to be redirected — check the roadmap first. See `CONTRIBUTING.md`. ## Model Used - OpenAI Codex coding agent (exact model ID and context window are not exposed to this runtime), reasoning and terminal/tool execution enabled. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: Paperclip <noreply@paperclip.ing>
