## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Apps connections give agents governed access to external services through vault credentials, grants, action policies, the tool gateway, and audit. > - Unikraft Cloud runs unikernel micro-VMs, services, and volumes across regional metros, and it offers a sandbox plugin for commands and files. > - Unikraft is not in the catalog. It has no hosted MCP server, so the generic "Connect your own MCP server" flow cannot reach it. > - Daytona (#16483) added a native REST pattern for this case: a catalog generated from the provider's published OpenAPI specifications and executed through the gateway. > - This pull request adds Unikraft on that pattern and moves the shared native-provider code into one registry, so the shared connection code does not name each provider. > - The benefit is governed agent access to all published Unikraft actions, with the token kept in the vault and sent only to published Unikraft hosts. ## Linked Issues or Issue Description Refs #16483 **Problem or motivation** Teams that run workloads on Unikraft Cloud want their agents to list instances, read logs, deploy and scale services, and run commands in sandboxes. Unikraft is not in the Apps catalog. Unikraft has no hosted MCP server, so operators cannot connect it through the remote MCP flow. **Proposed solution** Add a native Unikraft connection. Generate its actions from Unikraft's official OpenAPI specifications for the platform API and the sandbox plugin. Pin the specifications to a reviewed commit. The operator connects an API token. The token stays in the vault and goes only to the five published metro hosts. Every action takes an optional metro. Actions without a metro use the connection's default metro, which the operator can change under Advanced. **Alternatives considered** A catalog-only AppDefinition was not possible because no hosted MCP endpoint exists. Wrapping the `unikraft` CLI was rejected because it would expose host filesystem behavior and CLI login state. A second copy of the Daytona bridge was rejected; the shared transport and catalog contract are now one module with a provider registry. **Roadmap alignment** This extends the existing Apps and Connections provider coverage. It uses the existing credential, grant, policy, gateway, and audit model. It does not overlap planned core work. ## What Changed - Added `scripts/generate-unikraft-tools.mjs` and its tests. The generator reads the platform and sandbox plugin specifications at commit `5dd107ea1cd8716b83cb86a83ed2a6ee46f99b5b`, resolves shared parameters, records source SHA-256 hashes, and writes `server/src/services/unikraft/operations.generated.json`. - The catalog has 105 actions: 89 platform operations and 16 sandbox plugin operations. The server-sent audit event stream is recorded in the inventory and is not advertised as an action. - Classification: GET operations and sandbox reads and waits are reads. Delete, stop, suspend, detach, unpin, and sandbox command execution, signals, and stdin are destructive. All other operations are writes. - Added `server/src/services/connectors/unikraft/client.ts` and its generated catalog. It validates arguments against the generated schemas, accepts only published metros, rejects path traversal, sends JSON bodies on GET and DELETE as the specification requires, and verifies the token with `GET /v1/users/quotas`. A sandbox wait that times out (documented HTTP 408) returns a still-running result instead of a failure. - Moved the bounded, credential-redacting HTTP sender and the catalog contract helpers from `daytona.ts` to `native-rest-client.ts`. Added `native-provider-catalogs.ts`. `tool-access.ts`, the `tool-access/catalog` and `token-broker` modules, `connectors/tool-policy.ts`, and `tool-gateway.ts` now use this registry instead of Daytona-specific checks. Daytona behavior does not change. - Added the Unikraft definition source, the generated definition, the brand mark and manifest entry, and the permission review (`liveProof: not-run`). - Added `doc/connections/UNIKRAFT.md` with a sequence diagram, endpoints, setup, actions, and limits. Updated the connections README, the permission audit, and both capability maps. - Tests: definition shape, database-backed gateway reads, writes, deletes, and sandbox commands for personal and shared grants, default and per-call metros, rejection of unpublished metros and traversal, Off policies, revocation, stale-contract blocking, credential export denial, schema validation for all actions, pinned-transport tests for GET and DELETE bodies, and a browser setup check. ## Verification - `pnpm exec vitest run packages/shared/src server/src/__tests__/unikraft-connection.test.ts server/src/__tests__/unikraft-http-boundary.test.ts server/src/__tests__/daytona-connection.test.ts server/src/__tests__/daytona-http-boundary.test.ts server/src/__tests__/tool-access-service.test.ts server/src/__tests__/tool-gateway-service.test.ts server/src/__tests__/tool-gateway.test.ts ui/src/pages/apps/AppsConnect.test.tsx ui/src/pages/apps/Browse.test.tsx ui/src/lib/app-brand-assets.test.ts` plus `connector-tool-policy` and `tool-catalog-publication`: all passed after the rebase onto the split tool-access modules. - `node --test scripts/generate-unikraft-tools.test.mjs scripts/generate-daytona-tools.test.mjs scripts/app-brand-validation.test.mjs`: 20 passed. - `node scripts/check-app-brand-assets.mjs`, `node scripts/check-maps.mjs`, and `git diff --check`: passed. - `pnpm --filter @paperclipai/shared typecheck`, `pnpm --filter @paperclipai/server typecheck`, and `pnpm --filter @paperclipai/ui typecheck`: clean. - `npx playwright test --config tests/e2e/playwright.config.ts tests/e2e/unikraft-connector.spec.ts tests/e2e/daytona-connector.spec.ts`: 2 passed. - `node scripts/generate-unikraft-tools.mjs` regenerates the committed catalog with the recorded hashes. - Manual: on a local instance, open Connectors, search for Unikraft, and select **Add key**. Confirm the icon, the password field, the key guidance, and the default metro select under **Change**. - Not verified: a real Unikraft account. Live provider read and write proof is pending. ## Risks - A Unikraft token acts for the whole organization in every metro. Unikraft offers no narrower token permissions. Assign only trusted agents and review action permissions. - Sandbox actions run arbitrary commands inside the selected instance. They are classified as destructive. - A timed-out write can still complete at the provider. The bridge does not retry writes automatically. - New metros fail closed until the specification is regenerated and reviewed. Legacy `*.kraft.cloud` hosts are not reachable. - The Daytona refactor moves code without behavior changes. All Daytona tests pass without edits. - The generated JSON snapshot is large because it holds the provider input contracts. No migration or lockfile change is required. ## Model Used - Claude Opus 5.5 (Anthropic), model ID `claude-opus-5-5`, 1M context window, used through Claude Code with tool use (shell, file editing, web research, browser tests). ## 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
Paperclip agent access map
This map accompanies the feature map. It records APIs, agent entry points, permission boundaries and verification for the same capability IDs. The shared contract defines the format and maintenance rules.
Use full capability IDs when referring to access contracts outside their file:
onboarding/company means the company capability in onboarding.md in both maps.
The feature index lists feature and
capability IDs; IDs and references
explains entry-point references and stable naming.
Browse access contracts
The same-named feature recipes define navigation and capability IDs. Run
node scripts/storybook-catalog.mjs for the generated
maps/generated/agent-access-map.md index, or browse the
published feature guide.
Add or update the affected companion; there is no central registration or count.
Existing baseline source references describe the original inspection, not current verification. Record new executed evidence in the PR, issue, or CI artifact with its revision and scope. Do not refresh unrelated headers as bookkeeping.
Using an entry
Read its Policy and Gaps before selecting an agent path. Native fallback, legacy
REST/CLI, stdio MCP and a personal assistant connection can have different
authority and availability. Use a real admitted production binding; a scenario
declaration is not an installed tool. A restricted entry records current
enforcement and leaves any unresolved delegation decision visible.
For API catalog disagreements, follow the route/service authorization and record
discovery drift. For not-applicable, retain the concrete exception and local
path. Split shared business operations from client-only presentation.
Use maintain-verification-skill to reconcile changed source and both maps.
Use verify-paperclip and existing API/runner/MCP fixtures to collect the
permitted-agent and denial evidence; report blocked/not-run coverage honestly.
Run node scripts/check-maps.mjs after editing. The structural check does not
certify permissions, API catalog coverage, tool admission or live behavior.
Native REST transport
The call_api parity change reconciles affected baselines against
58e16dbddfc9c8d0cf60867f9d9847f0feda055b and the changes in this PR. Ordinary
REST operations use the same route authorization as legacy agent REST. Dedicated
tools remain optional for those operations; protocol endpoints still need their
existing clients. Board-only routes remain restricted for agent identity.
Native search_api / call_api requires operator rollout admission, a running
authorized native run, current task assignment and execution-run binding, company
and budget authority, task privacy, and a permitted work mode. Ask and Plan retain
mutation restrictions, and runs retain their admitted JWT scope during restart
recovery even when task mode changes. A waiting
agent does not gain independent native control just because a REST route exists.
Credential-bearing replies, including company exports and their legacy alias, stay inline under a 10 MiB limit and use encrypted mutation receipts. Other saved API snapshots are limited to the issuing actor and responsible user, plus authorized administrators. Artifact uploads enforce the same access checks as downloads; private snapshots are excluded from company exports and public company logos. Explicit deliverables use the existing sharing path. Native event history, checkpoints and completion records omit API bodies while preserving receipt metadata and replay digests. Restored webhook secrets use the same encrypted receipt and inline response policy as newly created webhook secrets. Task image access requires the company boundary and the task permission; skill-test and low-trust agents do not need company-wide browsing authority. Completion replay applies the same idempotent projection to stored and expected payloads; the run-log guide describes its fields.
Sources: API client,
catalog,
native authority,
credential storage classification,
snapshot access,
and history redaction. The affected entries remain
baseline and source-only; this reconciliation does not certify every operation.
Targeted real-route proof lives in the
API integration suite,
including owned routines, skill tests, scoped secrets, proposals and private export replay.
