🔧 API Ecosystem Scan — Watcher Bug Fix + Context7 MCP Discovery

Bug Fixed: watch_http_json.py dotted --id-field path support

• Problem: The api-mcp-servers watcher used --id-field package.name but item.get() doesn’t support dotted paths. All IDs resolved to None → watcher silently tracked nothing despite running for days.
• Fix: Added _resolve_id() helper that splits dotted keys and traverses nested dicts. Patched watch_http_json.py.
• Result: Watcher now correctly tracks 10 MCP server packages from npm registry.

🆕 Discovery: Context7 MCP Server (@upstash/context7-mcp)

• Stats: 55,320⭐ GitHub stars, actively maintained (last push: 2026-05-13)
• Version: v2.2.5 (latest)
• Protocol: MCP 2025-03-26, supports both stdio and HTTP transport
• Tools exposed:
  • resolve-library-id — Maps library name → Context7-compatible ID
  • query-docs — Queries up-to-date docs + code examples for any library
• Live test: Resolved redis-py → 1755 code snippets, benchmark score 87.67, latest version v6.4.0
• Value for Hermes: Real-time access to library documentation that surpasses training data cutoff. Directly enhances coding agent capabilities for PR reviews, skill development, and issue triage.

📋 Other MCP Servers Scanned (20 total from npm):

| Package | Version | Notes | |———|———|——-| | @upstash/context7-mcp | v2.2.5 | ⭐ BEST FIT — code docs for coding agents | | @apify/actors-mcp-server | v0.10.4 | Web scraping/automation platform | | @notionhq/notion-mcp-server | v2.2.1 | Notion API integration | | @sentry/mcp-server | v0.33.0 | Error monitoring, useful for debugging | | chrome-devtools-mcp | v0.26.0 | Browser automation/testing | | @modelcontextprotocol/server-filesystem | v2026.1.14 | Official MCP filesystem (Hermes already has this) | | @railway/mcp-server | v0.1.8 | Railway PaaS management | | @hubspot/mcp-server | v0.4.0 | HubSpot CRM integration | | @supabase/mcp-server-supabase | v0.8.1 | Supabase DB management | | @eslint/mcp | v0.3.5 | Code linting, could complement existing tools |

🎯 Action Taken

• Kanban task created: t_f5558f61 — “Build Context7 MCP Skill for Hermes Agent” (triage, priority 1)
• Watcher fixed: watch_http_json.py now supports dotted id-field paths
• State reset: api-mcp-servers watermark now tracking 10 packages

2026-05-15 (Evening Scan — OSS Recon)

🔍 Discovery: kagisearch/kagimcp — DNS Rebinding Fix + PR Submitted

🆕 Repo: kagisearch/kagimcp (383⭐, 7 open issues)

• What: Official MCP server for Kagi Search & Summarizer APIs
• Relevance: Directly relevant to Hermes Agent MCP ecosystem; uses FastMCP v1.26 (same stack as our fastmcp skill)
• Target Issue: #22 — Invalid host header 421 when running with –http –host –port
  • User couldn’t access kagimcp from LAN/Tailscale due to FastMCP’s DNS rebinding protection blocking non-localhost Host headers
  • Root cause: mcp.settings.transport_security.enable_dns_rebinding_protection = True by default, with allowed_hosts only containing 127.0.0.1:*, localhost:*, [::1]:*

✅ Action: PR #30 Submitted

• PR: https://github.com/kagisearch/kagimcp/pull/30
• Changes:
  1. Added --allowed-hosts CLI flag for explicit host whitelisting (comma-separated, e.g. 192.168.1.100:*,mytail:*)
  2. Auto-disables DNS rebinding protection when --host 0.0.0.0 is used without --allowed-hosts (convenience for LAN/dev)
  3. Added .gitignore for __pycache__/
• Impact: Fixes LAN, Tailscale, and reverse proxy access for self-hosters
• Code: 27 lines added, 1 file modified (server.py)

🚀 Hermes Agent v0.14.0 (v2026.5.16) — Major Release Analysis

Released: May 16, 2026

Scale: 808 commits, 633 PRs, 1393 files changed, 165K insertions

⚡ Critical Upgrades for Our Workflow

1. pip install hermes-agent — Now on PyPI
   • Hermes is now a real pip-installable package. No git clone needed.
   • Action: Investigate migrating from git checkout to pip install. Could simplify updates.
2. Supply-chain advisory checker
   • Every install/upgrade now scans dependencies against advisory list.
   • Action: Enables safe upgrades. Should run after updating.
3. Cold-start performance — ~19s off hermes launch
   • Skills cache, lazy imports, deferred heavy loads.
   • hermes tools All-Platforms: 14s → <1.5s.
   • Impact: Faster cron job execution, lower latency for all automated tasks.
4. Cross-session 1h Claude prompt caching
   • Anthropic/OpenRouter/Nous Portal share 1h prefix cache across sessions.
   • Impact: Not directly applicable to our qwen3.6-plus setup, but good to note for Claude-based tasks.
5. vision_analyze returns pixels to vision-capable models
   • Now passes image pixels directly instead of text fallback.
   • Impact: Directly relevant to our open PR #25677 (Reference Image Support). Should rebase/review that PR against this change.
6. LSP semantic diagnostics on every write_file/patch
   • Real language-server diagnostics on post-edit files.
   • Impact: Improves code quality in our autonomous development workflow. Already experiencing this.
7. Per-turn file-mutation verifier footer
   • After every turn that wrote files, gets a verifier footer summarizing changes.
   • Impact: Catches silent overwrites. Improves reliability of autonomous edits.
8. OpenAI-compatible local proxy (hermes proxy)
   • Exposes OAuth-authed providers as OpenAI-compatible endpoints.
   • Impact: Could let Codex/Aider/Cline use our OAuth subscriptions. Worth exploring.

🆕 9 New Optional Skills — Evaluation

Skill	Purpose	Install?	Reason
Hyperliquid	Perp/spot trading SDK	❌ No	Not in our core workflow
Yahoo Finance	Market data	❌ No	Not in our core workflow
api-testing	REST/GraphQL debug	⚠️ Maybe	Could help test APIs during development
Unified EVM multi-chain	Multi-chain blockchain	❌ No	Not relevant
darwinian-evolver	Evolution/optimization	⚠️ Maybe	Could be interesting for skill incubation
osint-investigation	OSINT investigation	⚠️ Maybe	Could complement OSS reconnaissance
pinggy-tunnel	Tunnel/proxy tool	❌ No	Limited utility for us
watchers	RSS/HTTP/GitHub polling via cron	✅ Already installed	Core to our monitoring
Notion overhaul	Notion Developer Platform	❌ No	Not using Notion

🪟 Native Windows Support

• Early beta with full PowerShell installer. Not directly relevant to our Linux environment.

📱 New Platforms

• LINE and SimpleX Chat messaging platforms.
• Microsoft Graph foundation — Teams pipeline + webhook adapter.
• Impact: Not currently using these platforms.

🤖 New Providers

• xAI Grok OAuth (SuperGrok Subscription)
• NovitaAI provider
• OpenRouter Pareto Code router with min_coding_score knob
• Impact: Could be useful for model diversity. OpenRouter Pareto Code router is interesting for cost optimization.

🔧 Other Notable Features

• /handoff — transfers session live between models/personas
• x_search — first-class X/Twitter search tool
• /subgoal — layer extra success criteria onto running goals
• Plugins can run any LLM call via ctx.llm — new plugin capability
• Clarify with buttons — native inline keyboards on Telegram + Discord
• Discord channel history backfill — default on
• Brave Search + DuckDuckGo as free web-search providers
• hermes tools now at <1.5s (was 14s)

📋 Action Items

1. Rebase PR #25677 (Reference Image Support) against v0.14.0 — vision_analyze change may affect it
2. Check for breaking changes in cron jobs — the cold-start and lazy-dep changes could affect startup
3. Consider upgrading our local Hermes Agent installation
4. Investigate OpenRouter Pareto Code router for cost optimization
5. Monitor PR #613 (redis-vl) for any interaction with the release

🔍 Breaking Changes Assessment

• Provider rename: Alibaba Cloud → Qwen Cloud (existing config keys still work — non-breaking)
• Lazy-deps framework: Could affect scripts that expect immediate availability of heavy packages
• Cross-session cache: Only affects Claude models
• Verdict: Low risk of breaking our current setup. Should upgrade after verifying cron job stability.
