Devin Foley 059ae49cab feat(connections): add Unikraft Cloud connection (#17139)
## 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

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).

Paperclip maps

The maps describe the same capabilities from two perspectives:

  • Feature map: what a person can do, where to reach it, and how to verify the user journey. Preserve its Poteto format.
  • Agent access map: the APIs and agent entry points for those capabilities, their permission boundaries, and access verification.

These are sibling directories under maps/. Each feature file has a same-named agent access companion. Reuse the product map's sub-feature IDs, so tasks/create identifies the same capability in both maps. Product behavior remains governed by the implementation spec; a map cannot grant authority or redefine a permission denial as success.

Capability identifiers

The feature ID is the recipe filename without .md, such as onboarding. The full capability ID joins that feature ID and a Sub-features key with /: the company key in feature-map/onboarding.md is onboarding/company. Its agent-access-map/onboarding.md companion uses the same local company key. The feature-map index lists the existing feature and full capability IDs.

Each child page states Feature ID: `onboarding`. after its introduction or product-map link. In feature recipes, show the full ID beside the parsed local key: - `company`: `onboarding/company` — create a company. In access companions and Storybook verification guidance, keep the existing local heading and put Capability ID: `onboarding/company`. beneath it. These labels make the existing identifiers visible without changing keys, anchors, or ID generation.

Use full capability IDs in cross-feature references, Storybook annotations, tests, issues, PRs, and verification evidence. Both segments use lowercase letters, digits, and hyphens. Keep filenames and keys stable when display titles or navigation labels change; renaming either changes the capability ID.

Entry-point IDs describe a surface, such as web-wizard, and are scoped to their recipe. Reference them with a recipe link, such as onboarding.md#web-wizard, and record the capability exercised separately. Navigation section labels are not capability IDs. See IDs and references for examples.

Access contract

Every business operation needs both an API and a usable agent entry point for an actor authorized to perform it. A dedicated tool is optional when REST, the CLI, an assigned MCP client, or native search_api / call_api already provides the operation. Record which agent surfaces actually have that path; an installed CLI or optional MCP package cannot be assumed available to every native/remote run.

Track these independently:

Dimension Values and meaning
API present, missing, not-applicable, or unreviewed. Use exact methods/paths; distinguish protocols from REST.
Agent access available, partial, missing, restricted, operator-only, not-applicable, or unreviewed. Name the supported surface and actual entry point.
Policy Actor, action/grant, company/resource/ownership scope, responsible-user intersection, run requirements, work modes, and gates relevant to the operation.
Evidence source-only, verified, failed, blocked, or not-run. Source presence and successful board calls are not agent verification.
Review depth baseline records representative operations and known gaps; operation-reviewed enumerates the capability's meaningful operations and their individual access contracts.

Broad capabilities such as task properties must be split into operations before they count as operation-reviewed: renaming, metadata edits, assignment, dependencies, and lifecycle changes can use different tools and permission rules. An available read path cannot certify a write path. List/get/create/update/delete, execution/control, credential handling, and resolution are separate where their authority or transport differs. Do not duplicate request schemas from OpenAPI.

Exceptions and restrictions

Presentation-only state, static developer fixtures, and pre-start/local operator work may use not-applicable for a domain API, with a concrete reason and the existing local path. When a capability combines shared data with presentation, split the operations: browser recents do not exempt resource lookup from API coverage. Promoting local state to a shared feature requires revisiting the entry.

A board-only endpoint is restricted for agent identity, not an automatic exception or a missing API. Cite the enforced policy and record whether the agent can request the authorized human's action and observe its result. An unresolved delegation question remains in Gaps. Company access, a job title, a personal assistant's OAuth grant, or an accepted interaction does not grant board identity. Keep budget, approval, secret and execution authority intact.

Check actual route/service authorization and production tool admission. OpenAPI actor labels and scenario/evaluation tool declarations are supporting metadata; record disagreements rather than using them as proof of access. Native API fallback restrictions, tool field/scope limits, and rollout settings are part of the agent path, even when a legacy agent can call the REST endpoint directly.

Companion file format

Each agent-access-map/<area>.md has an H1, a relative link to its product file, and its feature ID, followed by one H2 backticked local key per product sub-feature. Each capability starts with its full capability ID and contains these fields:

  • Review: baseline or operation-reviewed.
  • API: presence state and exact operation IDs, or a reasoned exception.
  • Agent access: availability state and concrete entry points by surface.
  • Policy: relevant permission and runtime boundaries, with source references.
  • Evidence: evidence state, reviewed commit and sources or executed proof.
  • Verification: allowed/denied assertions and observable result; record what has actually run separately from the proposed recipe.
  • Gaps: missing APIs/paths, discovery drift, unreviewed operations or policy decisions; use none only for the enumerated scope that was reviewed.

For an operation-reviewed capability, use H3 backticked operation IDs and repeat API, Agent access, Policy, Evidence, Verification and Gaps for each operation. Use small operation names such as create, update, read, or run-now. The enclosing capability has Review: operation-reviewed only after its meaningful operations have been enumerated. The following excerpt shows one operation; include the others before using that review label:

## `definition`

Review: `operation-reviewed`.

### `create`

API: `present` — POST /api/companies/{companyId}/routines.
Agent access: `available` — agent REST, CLI routine create and native call_api
under the enabled rollout and active-run/mode gates.
Policy: same company; assigneeAgentId must be the calling agent; cite the
routine authorization and native API policy sources.
Evidence: `source-only` — reviewed commit and source links; no live proof.
Verification: `not-run` — create an owned routine; reject assignment to another
agent; inspect saved configuration, attribution and retry behavior.
Gaps: verify ownership and responsible-user resolution with a permitted agent
context; source presence alone does not qualify this operation.

Keeping the maps synchronized

When a change adds/removes a capability or changes its behavior, API, permission, tool binding, CLI support, or work mode, update the affected companion and product recipe as appropriate in the same change. Preserve IDs across renames where the capability is unchanged; update the affected cross-links together. Indexes discover recipes automatically. An API-only change may update the companion without rewriting unchanged user instructions.

maintain-verification-skill owns reconciliation of both maps. It follows changed source and authorization, checks real agent reachability, and records product gaps without implementing them during a maintenance pass. The creation skill uses this structure. verify-paperclip consumes the relevant recipes and reports evidence/drift; map editing belongs to maintenance.

Run the structural check after map changes:

node scripts/check-maps.mjs

It checks paired areas/IDs, navigation metadata, required fields, and local references. It does not certify endpoint authorization, production bindings, operation completeness, or live behavior. Source audits must check those against the existing API and tool contracts; avoid a second schema catalog or runtime.

For live access proof, use Paperclip's existing API/runner/MCP fixtures or an owned isolated instance. Use the actual agent identity, target and work mode. Assert the allowed result and relevant denial (another company/private resource, wrong owner, missing grant, invalid run, restricted mode or resolver). Mutations also need persisted state/attribution and retry behavior. Capture evidence using the existing artifact workflow; keep executed run results separate from generated maps/generated/coverage.json, which lists page references.

Local authorship and generated indexes

Change only the recipes, access contracts and stories whose behavior or intent changed. Feature recipes own navigation metadata; stories own small parameters.paperclip annotations. Keep the feature-map README's readable ID index aligned with those sources; it does not register entries for generation. Do not refresh counts in shared READMEs, inventories, fingerprints or review journals.

node scripts/storybook-catalog.mjs validates and generates aggregate navigation, Storybook data, verification routes and the page inventory. All outputs live in ignored maps/generated/, ui/storybook/generated/, and the ignored Storybook preview.tsx wrapper. Start/build and UI typechecking generate their own inputs. A clean merged checkout therefore assembles both branches' changes automatically.

Git provides history and diffs. PRs, issues and CI artifacts retain review/run evidence for the named revision. Capability associations do not create whole-file review dependencies. Keep durable scenario limits in the affected recipe or story.
