Devin FoleyandPaperclip 0b62c736a0 feat(connections): add generic Daytona API and Toolbox access (#16483)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Apps connections give agents controlled access to external services.
> - Daytona provides sandbox, file, command, Git, and account APIs.
> - Operators need to assign this access without exposing a server
credential.
> - A small task-specific tool list cannot serve general Daytona work.
> - This pull request adds the published HTTP actions through the
existing connection gateway.
> - Operators keep control of identity, agent access, and each action.

## Linked Issues or Issue Description

**Problem or motivation**

Paperclip has a Daytona sandbox provider for its own execution
infrastructure. It lacks a normal Apps connection for agents to manage
an operator's Daytona account. Reusing the server's provider credential
would bypass normal connection ownership and action permissions.

**Proposed solution**

Add a Daytona connection with personal or shared vault credentials.
Generate its action catalog from the official platform and Toolbox API
specifications. Use the existing run-bound gateway, grants, action
policies, approvals, revocation, and audit paths. Sandbox IDs come from
Daytona; tools need no Paperclip task or lease ID.

**Alternatives considered**

A four-action diagnostic subset cannot support general provider work.
Launching the provider CLI would expose host filesystem behavior. Native
OAuth is not included because a supported third-party registration path
was not verified. The native method uses an organization API key.
Existing Composio setup is a separate possible OAuth route and is not
qualified by this change.

**Roadmap alignment**

This extends the existing Apps and Connections provider coverage in
`ROADMAP.md`. It uses that system's credential and permission model.
GitHub searches found no existing Daytona Apps connector PR or issue.

## What Changed

- Add the Daytona catalog entry, provider source override, official
theme logos, permission review, and setup documentation.
- Generate 274 HTTP actions: 169 platform and 105 Toolbox operations.
Record two WebSocket upgrades separately; do not advertise them as HTTP
tools. Record source URLs and hashes.
- Add provider-focused execution for sandboxes, snapshots, volumes,
files, Git, commands, computer use, and account resources. Provider
authority still limits which endpoints accept an organization key.
- Validate action arguments. Resolve Toolbox targets through the fixed
platform API. Check sandbox identity and organization before using an
approved Daytona proxy. Keep normal guarded network requests and vault
resolution.
- Transfer file bytes without reading or writing host files. Share one
caller deadline across prerequisite reads, dispatch, and response
reading. Bound requests and responses. Do not automatically retry writes
with unknown outcomes. Redact the selected credential from results and
errors.
- Classify credential access, access changes, interactive input, command
execution, file permissions, and deletion (including TTL and
auto-delete) as destructive actions. Keep new and changed actions under
catalog review.
- Upgrade saved catalogs and retire the earlier diagnostic names. Hide
retired actions from the UI and agent discovery even when provider
refresh fails. Preserve existing action choices and historical records.
Reject stale same-name contracts during agent discovery and dispatch
before a board refresh.
- Add database-backed gateway and catalog-upgrade regressions, schema
generator tests, a browser setup check, and both capability map updates.

## Verification

- Passed on the review-fix head: 57 focused Vitest cases (18 Daytona
database/client cases, five HTTP boundary cases, and 34 shared catalog
cases), four generator tests, `pnpm -r typecheck`, and `pnpm build`. The
five HTTP cases use a real local server through the pinned production
transport. The normal browser setup check and 17 generator/artwork cases
passed on the initial PR head; those UI and artwork paths are unchanged.
- Passed on this branch: brand asset validation, token gates, map
structure checks, and `git diff --check`. All latest-head GitHub checks
pass on `ea979ccb3a64dc9508807823540f935c4316ea35`. Apex is 5/5, with
all five findings addressed and zero unresolved threads. The branch has
no merge conflicts.
- The initial catalog-generation command could not find the external
research corpus. The supported `--definitions-only` mode regenerated the
definitions successfully. Unrelated generated drift was excluded.
- An earlier full local Vitest attempt on the preview branch failed when
bundled PostgreSQL could not start on macOS. After replay onto current
master, all three unchanged event-sequencing cases pass with bundled
PostgreSQL; the earlier startup cause remains uncertain.
- The first full-suite command on this branch used my external test
database override. Chat fixtures require a current migrated schema and
failed because `agents.lifecycle_state` was absent in that disposable
database. A focused comparison reproduces failure with the override and
passes with normal setup. That attempt was stopped, and the full suite
restarted without the override. Focused Daytona cases use their own
migrated PostgreSQL 16 databases.
- The clean local full-suite attempt recorded embedded PostgreSQL
startup failures in two unchanged native-runtime cases and two failures
in unchanged Git fixtures. It was stopped after these failures were
isolated; no full local suite pass is claimed. The 15 matching
native-runtime cases pass separately. The Git cases fail with the local
`init.defaultBranch=main` setting and pass with `GIT_CONFIG_COUNT=1
GIT_CONFIG_KEY_0=init.defaultBranch GIT_CONFIG_VALUE_0=master` limited
to the test command. No global Git setting was changed. Full Linux CI is
green.
- Fixtures use real database persistence and run-bound gateway sessions
with provider responses replaced by fixtures. They cover personal/shared
vault ownership, reads and writes, file bytes, Off policies, revocation,
organization mismatch, untrusted proxy rejection, output bounds, saved
catalog upgrades, failed refresh, and permission preservation.
- The first Apex review found five valid issues: multipart transport
compatibility, destructive classification, caller deadlines, audit
filters, and stale saved contracts. All five were fixed with regressions
before the second review. A typecheck then found the nullable saved
schema hash; admission now accepts that stored type and rejects null as
stale.
- The browser check covers setup controls without submitting a provider
key. No real Daytona account, provider write, native OAuth flow, or
agent model run is qualified. Live provider read/write proof remains
pending a test account.

## Risks

- Daytona keys have broad Toolbox authority, including keys with no
selected resource scopes. Only assign this connection to trusted agents
and review its action permissions.
- Remote writes or commands can continue after a timeout. Calls do not
automatically retry an uncertain outcome.
- The bridge targets Daytona Cloud. Proxy hosts are restricted; an
unrecognized future regional host fails closed.
- Files and responses have an 8 MiB bound. Each action has one caller
deadline, capped at 30 seconds across all provider requests and response
reading. Interactive WebSocket sessions are not exposed as HTTP actions.
- The generated JSON snapshot exceeds 1,000 lines because it holds the
provider input contracts. Generator logic and execution code remain in
separate small modules. Updates require explicit regeneration and
catalog review.
- No database migration or lockfile change is required.

## Model Used

OpenAI Codex, GPT-6. The runtime identifies the model family but does
not expose the exact backend model ID or context window. Used reasoning,
repository inspection, code editing, shell tools, database verification,
and browser tests.

Apps, Connections, and Integrations

Audience: internal engineers and product contributors working on integrations.

Start here when adding a provider: Connection authoring runbook. It is the canonical agent tutorial from provider research and protocol classification through manifest generation, branding, secrets, deterministic tests, real-account proof, and PR submission.

Runtime authentication: AI Connections.

Long-term memory: Experimental memory connectors.

Provider notes: Google Workspace, Gmail, Asana, Sentry, PostHog, Neon, Superagent, Gauge, AgentMail, Telem.AI, iMessage Photon, and Enterpret. Optional credential custody: Vercel Connect.

Post-read action: classify a new integration request, pick the right Paperclip layer to change, and avoid creating a parallel connection framework.

Decision Record

Board decisions from PAP-13211 make the Apps v2 substrate on the PAP-10341 branch canonical:

  • D1: Apps v2 is the substrate. The active model is tool_applications, tool_connections, catalog entries, profiles, policy rules, action requests, gateway sessions, audit events, and runtime slots. Connections v1 is retired as an implementation path.
  • D2: one credential authority per connection, brokered projections. The default is the Paperclip instance vault: durable third-party credentials live in company_secrets as secret refs. A reviewed remote MCP method may instead opt in to Vercel Connect, in which case Vercel is the durable credential authority and Paperclip stores only the connector reference and redacted grant metadata. A connection must never mix those two sources. Adapter config, plugin config, harness credential files, and run environments may receive only brokered or projected credentials.
  • D3: the vocabulary and three-door IA are product law. The default product doors are Apps, Connections, and Review. Protocol and operator-depth concepts live behind Developer or Advanced surfaces.
  • D4: unification lands on PAP-10341. Pages, CircleBack-style harness MCP OAuth, provider gallery work, and plugin-provided integrations converge on this branch instead of spawning new integration substrates.
  • D5: inbound stays thin. External clients that call Paperclip use scoped Paperclip tokens and existing profiles/rules. They do not get a separate permission model.

Canonical Object Model

Use connection as the unifying noun. A connection is four things:

  1. A stored credential reference.
  2. A capability catalog.
  3. A governance layer.
  4. An audit trail.

Everything else is an axis on that object:

Axis Values It answers
Direction outbound, inbound Who is the client?
Transport MCP, native REST/OpenAPI, OAuth app install, webhook How do bytes move?
Auth mode OAuth, API key/PAT, app installation, none What does the secret represent?
Credential owner company, user, run Whose identity acts?
Packaging catalog entry, plugin, skill How does it ship?

MCP is a transport, not a product category. "Install the Discord app", "connect Google Drive", and "add an MCP endpoint" all produce governed connections with different transport/auth values.

Layer Stack

When you are unsure where a change belongs, place it on the narrowest layer that solves the problem:

Layer Owns Examples
Surface user-facing Apps, Connections, Review, Developer/Advanced screens gallery cards, setup wizard, review queue
Governance profiles, bindings, allow/ask-first/block rules, quarantine, audit read-only profile, ask-first write policy
Capability action catalogs, schemas, risk classes, changed-tool review search_issues, create_comment, schema hash
Credential company_secrets, OAuth broker, credential resolver, token broker Slack bot token ref, Google OAuth refresh token ref
Identity actor attribution and token exchange board user, agent run, first-party service identity
Transport how the external system is reached remote HTTP MCP, local stdio, REST/OpenAPI, webhook

The agent should not hold a durable provider credential. It should hold a Paperclip run/session token; the server or broker resolves the connection, checks governance, invokes the provider, and writes audit.

Identity vs. connections

Signing a user in and connecting a resource are different planes with different owners, different token profiles, and different homes. Do not merge them. This section is the public, connections-side statement of the identity model so connector implementers inherit the rule without depending on private identity-service documentation or re-deriving it.

Plane Question Lives where Token profile
P1. Sign-in methods Who are you? paperclip-id (id.paperclip.ing → Account) Minimal-scope provider tokens (openid email profile), used once to authenticate, encrypted at rest, never exported
P2. Connections (Apps) What may your agents touch? Paperclip App instances (tool_connections), acquired via the connect broker for hosted + self-hosted Rich-scope, long-lived resource tokens in the instance's encrypted vault; per-agent grants; risk-tier policy defaults
P3. Login with Paperclip Who may authenticate against us? paperclip-id OIDC provider + DB-backed client registry Our ES256 ID/access tokens issued by us to registered RPs (instances, the broker, future third parties)

Everything in doc/connections/ — the First-30 matrix, the connection authoring runbook, and the connect-broker work — lives on plane P2. It never acquires, stores, or brokers a P1 sign-in token.

The standing rule (D7)

Adopted as a standing rule (decision D7) with the identity-model plan. State it verbatim in any P2 design so the app-store work cannot drift into merging the planes:

Sign-in tokens are never reused as resource tokens; id.paperclip.ing never stores resource tokens; no connections hub on the ID service.

P2 tokens flow broker → instance vault as pass-through only; the id.paperclip.ing Account page therefore must not grow a "Connections" hub. The reasons to hold the planes apart (from the plan §3):

  • Scope discipline. Sign-in wants the narrowest grant; connections want deliberately broad ones. One button that does both is how you grant repo access just to log in.
  • Blast radius. id.paperclip.ing holding every customer's Vercel/Slack/GitHub resource tokens would make it the single juiciest target in the fleet; the broker is intentionally pass-through.
  • Self-hosted symmetry. Instances own their vaults, so self-hosters don't depend on our uptime to use their own connections.
  • Legibility. Sign-in and connections answer different user questions, and every product we benchmarked (Vercel, Railway, GitHub, Google) keeps them on separate pages with separate names.

The explicit Vercel Connect exception does not change D7 or merge P1 and P2. The operator chooses Vercel as the P2 credential authority for an individual connection. id.paperclip.ing is not involved, and neither sign-in tokens nor provider tokens pass through it. The deployment's Vercel access token or workload OIDC identity is bootstrap authority for that external vault, not a provider resource credential.

Naming alignment

Use the surface-correct name for each plane; they intentionally differ:

Surface Plane Name to use
Paperclip App instances P2 "Connections"
id.paperclip.ing Account P1 "Ways to sign in"
id.paperclip.ing admin P3 "OIDC clients" (until the app store productizes it)

Packaging Rule

Default to a catalog entry when an integration can be described as metadata: manifest, auth config, action catalog, resource filters, and policy defaults.

Use a plugin only when the integration needs product code such as custom UI pages, its own tables, workers, migrations, routines, or specialized ingestion. A plugin may bundle catalog entries, but it must not bypass the connection, profile, policy, credential, and audit model.

Use a skill for agent instructions. Skills may use connections; they must not own durable tokens.

  • Vercel Connect operator guide documents the optional external credential source, deployment flags, runtime resolution, recovery, and smoke requirements.
  • MCP access governance remains the operator runbook for the current gateway, profile, policy, approval, runtime, and audit APIs.

Migration Notes

Connections v1 contributed useful policy, UX, and rollout thinking, but its implementation branch is no longer the target. When you see old tickets or code using connections, connection_grants, or a provider-directory mental model, translate the intent into Apps v2:

Connections v1 intent Apps v2 home
Provider directory Apps gallery / tool_applications
Configured provider instance Connection / tool_connections
Grant allowlist Profiles, profile bindings, policies
Resource filters Policy/profile conditions plus provider config
Tool broker Tool gateway and runtime supervisor
Connection UX tail Apps, Connections, Review, Developer/Advanced IA

Do not add new work to the retired v1 branch. If an old ticket still describes a valid product gap, retarget it to an active Apps v2 issue or close it as superseded with a link to the replacement.
