## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Agents can receive governed access to connected apps through the runtime MCP gateway. > - A connected app can become unavailable when its sign-in expires or its health state needs attention. > - The native runner treated that optional app state as a fatal runtime setup error. > - One unavailable app could therefore stop all unrelated agent work. > - This pull request removes the fatal dependency and keeps the available app assignment immutable. > - The benefit is that an agent can continue its work while the stream tells the user which app needs reconnection. ## Linked Issues or Issue Description **What happened?** An agent could not start a native run when one assigned app connection was disabled, degraded, failed, or missing its secret. Runtime context creation or MCP delivery threw an error before the agent could do unrelated work. **Expected behavior** The run must continue without the unavailable app. Healthy assigned apps must remain available. The stream must explain which app needs reconnection. A changed assignment must not give a native run new access after its immutable context is captured. **Steps to reproduce** 1. Assign an MCP app connection to a Paperclip Runner agent. 2. Set the connection to a state that needs attention, such as `degraded`. 3. Start a task run for that agent. 4. Observe that native runtime setup fails before the agent starts. **Paperclip version or commit** Reproduced from `ee2a19062`. The branch is rebased on `dda4dff64`. **Deployment mode** Local development from source with embedded Postgres. No matching public issue or open pull request was found in the GitHub search. ## What Changed - Filter unavailable assigned app connections from the immutable native runtime MCP snapshot. - Keep healthy assigned connections and their tools in the snapshot. - Replace the fatal native MCP availability check with an optional stream warning callback. - Withhold MCP delivery when the current assignment digest does not match the captured native context. - Prevent a warning delivery failure from stopping the agent run. - Add regression tests for disabled, degraded, mixed healthy and unavailable, and assignment-drift cases. ## Verification - `pnpm exec vitest run server/src/services/native-runtime/runtime-context.test.ts server/src/__tests__/heartbeat-runtime-mcp-servers.test.ts` passes with 8 tests. - `pnpm -r typecheck` passes. - `pnpm check:token-gates` passes. - `pnpm build` passes. - `pnpm test:run` was attempted. Unrelated workspace runtime and port-exposure tests failed on this macOS host. The same files also failed when run without the changed MCP tests. The changed MCP tests remained green. Clean GitHub CI is the final full-suite check. ## Risks - Low migration risk. This change has no schema or API contract migration. - An unavailable app is absent from the run MCP surface until it is reconnected and a later run captures it again. - Assignment drift fails closed. The agent keeps running, but the changed gateway is not delivered. - This pull request does not auto-block the issue before the agent decides that the app is required. It emits reconnect guidance in the stream. The existing connection-request interaction remains the path for a required app. > For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and discuss it in `#dev` before opening the PR.

The runtime did not expose the context-window size. ## 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 - [ ] All Paperclip CI gates are green - [ ] 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>
