Implements mTLS for securing agent-to-agent communication in the Hermes
fleet. Fixes#806.
Changes:
- scripts/gen_fleet_ca.sh: generate a self-signed Fleet CA (4096-bit RSA,
10-year validity) that signs all agent certificates
- scripts/gen_agent_cert.sh: generate per-agent certs (Timmy, Allegro,
Ezra) signed by the fleet CA with SAN entries and clientAuth/serverAuth
extended key usage
- agent/mtls.py: new module providing:
- build_server_ssl_context() — TLS_SERVER context with CERT_REQUIRED,
enforces client cert against Fleet CA
- build_client_ssl_context() — TLS_CLIENT context for outbound A2A calls
- MTLSMiddleware — ASGI middleware that rejects unauthenticated requests
to A2A routes (/.well-known/agent-card*, /api/agent-card, /a2a/) with
HTTP 403 when mTLS is enabled
- is_mtls_configured() — checks HERMES_MTLS_CERT/KEY/CA env vars
- hermes_cli/web_server.py: wire MTLSMiddleware into the FastAPI app;
pass SSL context to uvicorn when HERMES_MTLS_* env vars are set so
the server runs TLS with mandatory client cert verification
- ansible/roles/hermes_mtls/: Ansible role to distribute Fleet CA cert,
agent cert, and agent key to fleet nodes; writes an env file with
HERMES_MTLS_* vars and restarts the hermes-gateway service
- ansible/fleet_mtls.yml: fleet-wide playbook referencing the role for
Timmy, Allegro, and Ezra nodes
- tests/test_mtls.py: 15 tests covering is_mtls_configured, SSL context
creation with real cryptography-generated certs, and MTLSMiddleware
(unauthorized agent rejected → 403, authorized agent accepted → 200)
mTLS is opt-in: set HERMES_MTLS_CERT, HERMES_MTLS_KEY, and HERMES_MTLS_CA
to enable. When unset, the server behaves exactly as before.

When the gateway responds to the health probe but the local
gateway_state.json has a stale 'stopped' state (common in cross-container
setups where the file was written before the gateway restarted), the
dashboard would show 'Running (remote)' but with a 'Stopped' badge.
Now if the HTTP probe succeeded (remote_health_body is not None) and
gateway_state is 'stopped' or None, override it to 'running'. Also
handles the no-shared-volume case where runtime is None entirely.
The probe was appending '/detailed' to whatever URL was provided,
so GATEWAY_HEALTH_URL=http://host:8642 would try /8642/detailed
and /8642 — neither of which are valid routes.
Now strips any trailing /health or /health/detailed from the env var
and always probes {base}/health/detailed then {base}/health.
Accepts bare base URL, /health, or /health/detailed forms.
The dashboard's gateway status detection relied solely on local PID checks
(os.kill + /proc), which fails when the gateway runs in a separate container.
Changes:
- web_server.py: Add _probe_gateway_health() that queries the gateway's HTTP
/health/detailed endpoint when the local PID check fails. Activated by
setting the GATEWAY_HEALTH_URL env var (e.g. http://gateway:8642/health).
Falls back to standard PID check when the env var is not set.
- api_server.py: Add GET /health/detailed endpoint that returns full gateway
state (platforms, gateway_state, active_agents, pid, etc.) without auth.
The existing GET /health remains unchanged for backwards compatibility.
- StatusPage.tsx: Handle the case where gateway_pid is null but the gateway
is running remotely, displaying 'Running (remote)' instead of 'PID null'.
Environment variables:
- GATEWAY_HEALTH_URL: URL of the gateway health endpoint (e.g.
http://gateway-container:8642/health). Unset = local PID check only.
- GATEWAY_HEALTH_TIMEOUT: Probe timeout in seconds (default: 3).
Addresses responsible disclosure from FuzzMind Security Lab (CVE pending).
The web dashboard API server had 36 endpoints, of which only 5 checked
the session token. The token itself was served from an unauthenticated
GET /api/auth/session-token endpoint, rendering the protection circular.
When bound to 0.0.0.0 (--host flag), all API keys, config, and cron
management were accessible to any machine on the network.
Changes:
- Add auth middleware requiring session token on ALL /api/ routes except
a small public whitelist (status, config/defaults, config/schema,
model/info)
- Remove GET /api/auth/session-token endpoint entirely; inject the token
into index.html via a <script> tag at serve time instead
- Replace all inline token comparisons (!=) with hmac.compare_digest()
to prevent timing side-channel attacks
- Block non-localhost binding by default; require --insecure flag to
override (with warning log)
- Update frontend fetchJSON() to send Authorization header on all
requests using the injected window.__HERMES_SESSION_TOKEN__

- Add GET /api/model/info endpoint that resolves model metadata using the
same 10-step context-length detection chain the agent uses. Returns
auto-detected context length, config override, effective value, and
model capabilities (tools, vision, reasoning, max output, model family).
- Surface model.context_length as model_context_length virtual field in
the config normalize/denormalize cycle. 0 = auto-detect (default),
positive value overrides. Writing 0 removes context_length from the
model dict on disk.
- Add ModelInfoCard component showing resolved context window (e.g. '1M
auto-detected' or '500K override — auto: 1M'), max output tokens, and
colored capability badges (Tools, Vision, Reasoning, model family).
- Inject ModelInfoCard between model field and context_length override in
ConfigPage General tab. Card re-fetches on model change and after save.
- Insert model_context_length right after model in CONFIG_SCHEMA ordering
so the three elements (model input → info card → override) are adjacent.
The dashboard device-code flow (_nous_poller in web_server.py) saved
credentials to the credential pool only, while get_nous_auth_status()
only checked the auth store (auth.json). This caused the Keys tab to
show 'not connected' even when the backend was fully authenticated.
Two fixes:
1. get_nous_auth_status() now checks the credential pool first (like
get_codex_auth_status() already does), then falls back to the auth
store.
2. _nous_poller now also persists to the auth store after saving to
the credential pool, matching the CLI flow (_login_nous).
Adds 3 tests covering pool-only, auth-store-fallback, and empty-state
scenarios.
- Wrap module-level import from agent.anthropic_adapter in try/except
so hermes web still starts if the adapter is unavailable; Phase 2
PKCE endpoints return 501 in that case.
- Change authorize URL from console.anthropic.com to claude.ai to
match the canonical adapter code.
Add OAuth provider management to the Hermes dashboard with full
lifecycle support for Anthropic (PKCE), Nous and OpenAI Codex
(device-code) flows.
## Backend (hermes_cli/web_server.py)
- 6 new API endpoints:
GET /api/providers/oauth — list providers with connection status
POST /api/providers/oauth/{id}/start — initiate PKCE or device-code
POST /api/providers/oauth/{id}/submit — exchange PKCE auth code
GET /api/providers/oauth/{id}/poll/{session} — poll device-code
DELETE /api/providers/oauth/{id} — disconnect provider
DELETE /api/providers/oauth/sessions/{id} — cancel pending session
- OAuth constants imported from anthropic_adapter (no duplication)
- Blocking I/O wrapped in run_in_executor for async safety
- In-memory session store with 15-minute TTL and automatic GC
- Auth token required on all mutating endpoints
## Frontend
- OAuthLoginModal — PKCE (paste auth code) and device-code (poll) flows
- OAuthProvidersCard — status, token preview, connect/disconnect actions
- Toast fix: createPortal to document.body for correct z-index
- App.tsx: skip animation key bump on initial mount (prevent double-mount)
- Integrated into the Env/Keys page
* feat: web UI dashboard for managing Hermes Agent (salvage of #8204/#7621)
Adds an embedded web UI dashboard accessible via `hermes web`:
- Status page: agent version, active sessions, gateway status, connected platforms
- Config editor: schema-driven form with tabbed categories, import/export, reset
- API Keys page: set, clear, and view redacted values with category grouping
- Sessions, Skills, Cron, Logs, and Analytics pages
Backend:
- hermes_cli/web_server.py: FastAPI server with REST endpoints
- hermes_cli/config.py: reload_env() utility for hot-reloading .env
- hermes_cli/main.py: `hermes web` subcommand (--port, --host, --no-open)
- cli.py / commands.py: /reload slash command for .env hot-reload
- pyproject.toml: [web] optional dependency extra (fastapi + uvicorn)
- Both update paths (git + zip) auto-build web frontend when npm available
Frontend:
- Vite + React + TypeScript + Tailwind v4 SPA in web/
- shadcn/ui-style components, Nous design language
- Auto-refresh status page, toast notifications, masked password inputs
Security:
- Path traversal guard (resolve().is_relative_to()) on SPA file serving
- CORS localhost-only via allow_origin_regex
- Generic error messages (no internal leak), SessionDB handles closed properly
Tests: 47 tests covering reload_env, redact_key, API endpoints, schema
generation, path traversal, category merging, internal key stripping,
and full config round-trip.
Original work by @austinpickett (PR #1813), salvaged by @kshitijk4poor
(PR #7621 → #8204), re-salvaged onto current main with stale-branch
regressions removed.
* fix(web): clean up status page cards, always rebuild on `hermes web`
- Remove config version migration alert banner from status page
- Remove config version card (internal noise, not surfaced in TUI)
- Reorder status cards: Agent → Gateway → Active Sessions (3-col grid)
- `hermes web` now always rebuilds from source before serving,
preventing stale web_dist when editing frontend files
* feat(web): full-text search across session messages
- Add GET /api/sessions/search endpoint backed by FTS5
- Auto-append prefix wildcards so partial words match (e.g. 'nimb' → 'nimby')
- Debounced search (300ms) with spinner in the search icon slot
- Search results show FTS5 snippets with highlighted match delimiters
- Expanding a search hit auto-scrolls to the first matching message
- Matching messages get a warning ring + 'match' badge
- Inline term highlighting within Markdown (text, bold, italic, headings, lists)
- Clear button (x) on search input for quick reset
