## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - Governed MCP access spans contracts, runtime enforcement, adapters,
UI surfaces, and operator verification
> - The parity reference PR #9534 is too large for effective automated
or human review
> - The feature therefore needs a linear stack whose individual diffs
stay below the 100-file review limit
> - This pull request is split 1/8 and focuses on fixture and demo MCP
servers
> - The benefit is a standalone, testable review boundary while
preserving byte-for-byte parity at the top of the stack
## Linked Issues or Issue Description
- Related parity reference: #9534
- Problem: Developers need deterministic local MCP fixtures and visible
demo servers without pulling in the governed production runtime.
- Proposed solution: Adds the Google Sheets and KV demo MCP packages,
fixture catalog/servers, smoke harness, guide, and the root
smoke/typecheck registration hunks.
- Alternatives considered: keeping #9534 as one 403-file review, or
rewriting the feature to manufacture seams; both were rejected in favor
of path extraction plus compile-driven boundary moves.
- Roadmap alignment: this advances the existing governed MCP/tool-access
work already represented by #9534; it does not introduce a separate
roadmap initiative.
- Stack position: base branch is `master`.
- Merge policy: merge bottom-up, in order, only after the complete
eight-PR stack has been reviewed and the top-of-stack parity gate
remains empty.
- Requested review: QA for fixture and smoke coverage; Greptile on every
PR.
## What Changed
- Adds the Google Sheets and KV demo MCP packages, fixture
catalog/servers, smoke harness, guide, and the root smoke/typecheck
registration hunks.
- Keeps this PR below 100 changed files and independently typecheckable.
- Preserves the final tree from #9534 when combined with the other seven
stack levels.
## Verification
- `pnpm typecheck`
- `pnpm --filter @paperclipai/google-sheets-mcp-server test` — 27 tests
passed
- `pnpm --filter @paperclipai/kv-demo-mcp-server test` — 12 tests passed
## Risks
- The new packages add dependencies that are intentionally not committed
to `pnpm-lock.yaml`, per repository policy.
- Stack risk: merging out of order can expose incomplete layers;
mitigate by following the documented bottom-up merge policy.
- Parity risk: later edits to an intermediate branch can drift from
#9534; mitigate by re-running the empty top-of-stack diff before merge.

- Merge bottom-up only after full-stack review and an empty parity diff
at #9563.

## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Agent adapters are the boundary between the control plane and the
runtimes that actually do work.
> - Hermes support needs to be available as first-class local and
gateway adapters while still preserving the adapter-manager override
path for external packages.
> - The adapter work touches runtime execution, UI adapter metadata,
onboarding prompts, scoped credentials, release packaging, and smoke
coverage, so the handoff needs concrete verification rather than only
unit tests.
> - This pull request adds built-in Hermes local and Hermes gateway
support, keeps external adapter overrides compatible, and
documents/tests the gateway flow end to end.
> - The benefit is that operators can hire Hermes-backed agents without
a manual plugin install, while self-hosted installs can still
override/shadow the built-ins through Adapter manager packages.
## Linked Issues or Issue Description
No public GitHub issue exists for this exact Hermes built-in adapter,
gateway onboarding, and release-source work.
Problem description:
- Hermes local and gateway adapters need a public, reviewable source
path in the monorepo so package artifacts and built-in adapter behavior
match the application source.
- Operators need built-in `hermes_local` and `hermes_gateway` adapter
choices without losing the ability to install external Hermes packages
as overrides.
- Gateway onboarding needs secure defaults for API server URLs, API
keys, and generated agent setup text.
- Hermes-originated task bridge credentials need narrower API-key scope
configuration.
- Related public PRs found during duplicate search include #3027, #2363,
#7544, #7950, #8095, and #8543.
## What Changed
- Added the unified Hermes adapter package with local and gateway
server/UI/CLI exports, config schemas, transcript parsing, model
detection, and package metadata.
- Registered `hermes_local` and `hermes_gateway` as built-in adapters
across shared constants, server registries, CLI packaging, and UI
adapter registries.
- Kept the external adapter override path compatible so installed Hermes
packages can shadow built-ins and restore the built-in parser when
disabled.
- Added Hermes gateway onboarding docs, board-operator docs, Docker
smoke assets, and shell smoke harnesses for join/e2e validation.
- Added scoped task-bridge API-key support, authorization checks,
issue-origin handling, and tests for Hermes-created Paperclip tasks.
- Hardened gateway transport and redaction behavior for API keys,
headers, session data, and smoke diagnostics.
- Updated release packaging/bootstrap checks for the Hermes packages
while leaving `pnpm-lock.yaml` out of the PR per repository policy.
## Verification
Targeted local verification recorded before PR handoff:
- `pnpm --filter @paperclipai/hermes-paperclip-adapter exec vitest run
src/gateway/server/execute.test.ts` — 14/14 passed.
- `pnpm test:hermes-gateway-smoke` — 6/6 passed.
- Hermes package typecheck/build checks passed.
- Focused server/UI adapter tests passed — 31/31.
- Release helper Node tests passed — 18/18.
- `git diff --check origin/master..HEAD` passed.
Fresh Docker E2E smoke evidence:
- Ran `pnpm smoke:hermes-gateway-e2e` on 2026-06-26 with a fresh state
directory and fresh Docker container against a live Paperclip dev
server.
- Hermes direct execution reached `completed`.
- Hermes stop/cancel path reached `cancelled`.
- Hermes gateway created a Paperclip task, Paperclip ran the Hermes
agent, and the task reached `done` with the expected marker response.
- Temporary board auth keys, token files, smoke state, and Docker
containers were cleaned up after the run.
PR checks on head `b5eae40ce`:
- GitHub Actions passed: `policy`, `review`, `Typecheck + Release
Registry`, all general test shards, all serialized server shards,
`Build`, `Canary Dry Run`, `e2e`, and aggregate `verify`.
- External checks passed: Snyk and Socket Project Report.
- External Socket Pull Request Alerts remained pending after the
first-party CI matrix completed.
## Risks
- Medium risk: this spans adapter registration, package publishing,
gateway execution, onboarding docs, API-key scoping, and UI adapter
metadata.
- Migration risk is low: the scope-config migration adds a nullable
column and does not rewrite existing keys.
- Gateway execution depends on operator-provided Hermes API
configuration; the smoke covers the Docker gateway path but real
deployments may differ by network/auth setup.
- Direct Greptile review on the latest expanded diff is file-count
limited, although the commitperclip review gate passed.

- Dev watch: exclude adapter-plugins dir from tsx watcher
to prevent mid-request server restarts during reinstall
- All consumer fallbacks use getAdapterLabel() for consistent display
- AdapterTypeDropdown uses controlled open state for proper close behavior
- Remove hermes-local from built-in UI (externalized to plugin)
- Add docs for external adapters and UI parser contract
pnpm monorepo with shared packages, server, and UI workspaces.
