DottaandPaperclip 2d0c138122 Expand direct assistant MCP tools for work and configuration (#15380)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - People also use assistants in Codex, Claude, and other MCP clients.
> - The existing assistant connection can read work and create tasks or
comments.
> - It cannot edit tasks, exchange files, or manage normal agent and
project settings.
> - These operations must retain the person's permissions and
Paperclip's execution rules.
> - This pull request adds an explicit operation registry and separately
consented configuration access.
> - Assistants can manage work without receiving credentials or runner
authority.

## Linked Issues or Issue Description

**Subsystem affected**

Cross-cutting: assistant MCP, domain routes, consent UI, storage, and
Product E2E.

**Problem or motivation**

A connected assistant cannot update tasks, maintain documents, attach
files, or configure existing agents, projects, and skills. Users must
leave the assistant for these routine actions.

**Proposed solution**

Add named tools and a restricted API registry to direct connections.
Require separate configuration consent. Reuse domain routes and retry
receipts. File uploads save the attachment when the byte transfer
succeeds.

**Alternatives considered**

Arbitrary REST forwarding would expose administration and credential
operations. Runner impersonation would bypass execution ownership.
Separate upload completion calls add unnecessary client state.

**Roadmap alignment**

Checked ROADMAP.md and related MCP pull requests. This extends the
human-authorized connection from #14933. It does not replace the runner
or introduce agent impersonation.

Companion Cloud routing and directory isolation:
https://github.com/paperclipai/paperclip-cloud/pull/678.

## What Changed

- Add task editing, finish/block, documents/revisions, deliverables,
agent settings/instructions, projects/repositories, and skills/files.
- Add an allowlisted API search/call registry with identical field
restrictions, scopes, and retry identities.
- Add unchecked configuration consent. Existing write grants retain
their current authority.
- Add hashed, expiring file transfer tickets and atomic upload receipts.
No completion call is required.
- Preserve company boundaries, human attribution, active native
execution ownership, and execution review gates.
- Add protocol/domain tests, consent stories, and eight paid Product E2E
workflows.
- Repair two CI fixture races: await cold route setup before assertions,
and wait for asynchronously loaded connection copy. Both fixture suites
pass (24 + 48 tests).

## Verification

- Consent revision: one write-access checkbox controls requested work
and configuration permissions in browser and device flows. All 16
consent tests, UI typecheck/build and token gates pass. Updated
interactive stories cover default approval, opt-out and viewer
restrictions. The paid browser helper uses the new exact label. Real
GPT-5.4 Mini Product E2E passes 2/2 at
`64f96373118eb190f8cba1c2ab17cb979555f3ad` (configuration + permission
denial), campaign `local-2026-10-07T00-51-14-337Z`, no automatic
retries, cleanup passed; $0.04149375 estimated assistant cost plus
unpriced worker usage. Raw results, usage and source fingerprints are
retained in the worktree. UI and Product E2E typechecks pass.

- Prior head `2f246d4b74f1f98c75ebcb37ae6753a748237fac`: all 52 checks
pass; two optional Storybook checks skip. Greptile 5/5 on that head, no
unresolved review threads. Final consent head
`64f96373118eb190f8cba1c2ab17cb979555f3ad` also has all checks passing
and Greptile 5/5 with no unresolved threads. The unchanged Cursor
sandbox test had one 10-second timeout, passed in local isolation, and
passed its single CI rerun; the failed attempt remains in [the CI
run](https://github.com/paperclipai/paperclip/actions/runs/37554106934).
The existing chat retry-denial browser test had one visibility failure;
its single rerun passes, and the failed attempt remains in [the CI
run](https://github.com/paperclipai/paperclip/actions/runs/37542735691).

- Full workspace `pnpm -r typecheck` and `pnpm build` pass at final
runtime source `b2196fae1`. UI token gates pass.
- 139 MCP/OAuth/transfer/privacy tests and 76 grader calibration tests
pass, including one-connection PostgreSQL OAuth and concurrent upload
retries.
- Paid Product E2E: all eight expanded cases qualified across Mini,
Haiku and Sonnet. A merged-source repeat passed 23/24; one Haiku cell
timed out before application startup. Final affected-case qualification
passes 9/9 on all three models with grader v16, including the failed
cell. Automatic retries disabled; failures, costs, source hashes and
independent durable-state/file assertions are retained in [the
verification
record](doc/plans/2026-10-06-expanded-assistant-mcp-verification.md).
- Actual Codex CLI, Claude Code and OpenCode clients completed local
reads/mutations. Codex wrote a report, Claude updated it in a later
conversation, and OpenCode uploaded/downloaded a file with matching
SHA-256 and registered the attachment. Revoking the CLI grant rejects
subsequent bridge initialization.
- Butter staging is verified on final runtime `b2196fae1`
([deployment](https://github.com/paperclipai/paperclip-cloud/actions/runs/37538432138)).
A fresh OpenCode workspace fetched the copied invitation, configured
remote MCP, started OAuth and reached real consent with configuration
unchecked. Invalid transfer tickets return 403 through Cloud. Human
approval for the new persistent staging grant is pending; hosted
task/file success is not yet claimed. The final transaction fix is
deployed.
- Full local `pnpm test:run` passed 15,614 general-server tests but
stopped on two macOS timeouts. The heartbeat test passed in isolation;
the existing 40,000-file Git stress fixture timed out again. Its Linux
CI lane passes. Later local full-suite phases did not run after the
timeout; this is not an all-green local full-suite claim.
- Instructions and security limits are in `doc/public-mcp.md`; the saved
plan is `doc/plans/2026-10-06-expanded-assistant-mcp-tools.md`.

## Risks

- This expands the experimental direct MCP surface. Explicit schemas and
domain permissions must stay synchronized.
- Migration 0311 adds transfer tickets and upload receipts. Expired
orphan cleanup must not remove committed attachments.
- Configuration requires a new consent request containing that scope;
the single write-access choice controls it alongside work mutations.
Refreshing an old grant does not add it.
- The public directory keeps its original ten tools through the
companion Cloud change.
- Hosted consent/work proof remains the final delivery gate. The PR
stays draft while approval of the new staging grant is pending; code
checks and review are green. Merging is a separate action.

## Model Used

OpenAI Codex (GPT-6, tool use and code execution). The exact serving
model ID and context window are not exposed in this session. Paid
evaluation models: gpt-5.4-mini, claude-haiku-4-5-20251001;
claude-sonnet-4-6.
