Findings

• AgentLedger MCP: hosted at agent-ledger-production-0ff8.up.railway.app/mcp (Streamable HTTP). Five tools (ledger_track, ledger_set_budget, ledger_report, ledger_alerts, ledger_list_agents) with agent-secret write auth - reads open, writes require the secret issued on first track call. Budget caps enforced with a 402 at track time. Free beta up to 3 agents, Pro $19/mo via Stripe. Registry io.github.entradox/agent-ledger. Same vendor as Perimeter Watch, Agent Watch, TrustScan and QuoteOS. Category: Finance.
• Vibe Prospecting MCP: hosted at vibeprospecting.explorium.ai/mcp (Streamable HTTP, browser OAuth, no API key). Explorium's B2B data: company search, contact discovery/enrichment, firm research (firmographics, technographics, funding, competitors), sample-first previews with explicit CSV exports. Per-client walkthroughs for Claude Code/Desktop, Codex, Gemini CLI, Manus and Hermes. Category: Lead Generation & Web Scraping.
• Wafeq MCP: community MIT server (github.com/ohneben/Wafeq-MCP) exposing all 251 Wafeq Public API endpoints as spec-generated tools plus 2 handwritten ones - 253 total, tagged with 9 safety categories and readOnlyHint/destructiveHint annotations. stdio or Streamable HTTP via Docker (localhost:8765), idempotency keys on 146 write endpoints, whole-period report validation, tenant verification at startup. Registry io.github.ohneben/wafeq-mcp. Category: Finance.
• Agent Watch MCP: hosted at agent-watch-api-production.up.railway.app/mcp.

Open probe API (POST /v1/probe), watch API tied to checkout email. Free 5 endpoints, Builder $19/mo, Team $99/mo, Data API metered. Category: DevOps.
• Ultralayer MCP: hosted at api.ultralayer.ai/v0/mcp (OAuth or bearer from console.ultralayer.ai). Market news separating new information from repeats, developments with impact scores, event timelines, company outlooks, disclosure changes, stakeholder analysis, sentiment and alerts; point-in-time safety for backtests; MIT plugin repo. Listed on Glama, MCP Registry and Smithery. Category: Finance.
• TrustScan MCP: hosted at trust-scan-production.up.railway.app/mcp (Streamable HTTP, keyless, free). Two tools (trust_scan_server with typosquat check, trust_scan_file). Four check classes: invisible Unicode prompt-injection, dangerous patterns MCP001-MCP006 (eval/exec, shell, raw sockets, unsafe deserialization, obfuscated base64), hardcoded secrets, typosquat via Levenshtein distance. v0.1.0, registry io.github.entradox/trust-scan.

• Morning 404-shell supersessions: the morning sweep's author-slug 404 rulings (explorium-ai, artgas1, ultralayerhq) were based on author-level pages; full author/name detail paths resolved rich docs for Vibe Prospecting, Yandex Metrika and Ultralayer. Magenest Odoo's full path (magenestjsc/advanced) confirmed 404 - remains a shell.

Non-Catalogued (Disposed or Repeats)

• QuoteOS: keyless insurance-quoting middleware (checkEligibility, getAutoQuotes, getHomeQuotes) but synthetic sandbox data only - premature per the Krimskrams rule.
• Magenest Odoo: mcpservers detail page 404 shell (confirmed this sweep).
• PRIMAMCP: German-language legal research from official sources (8 named tools) - morning disposition as geo niche respected.
• Onymu: thin tagline-only mcp.so listing.
• priostack: agent context/memory orchestration SDK - agent memory infra class, Memwyre precedent.
• LinkScale: link-in-bio platform detail page with no MCP endpoint or tool docs - thin docs (morning disposition).
• Repeats already disposed by the morning sweep: WattScope, AgentRender, Collide, Kontexta, Rogue, Torquantis, VitaeContext, Lexicon, ContextSwitch, Flash, Index TTS, Surli, Nullheim, 3DAssets Dev, ARADIA, FlightPowers, Seedance, dxpert UNS, adult-search trio (NudiTok, Desaira, tik-tok.porn), remaining 404 shells.
• Feed repeats already catalogued or disposed: Artlist, Ultimate Web Scraper, Emailchaser, DCA Method, SoundGTM, Expired Domains, Mailercloud, InstantClips, JsonCut, Fundz, Rechnungslotse, Countersignatory, Formdall, LoomaScale, Beamtrace, PostNitro, Yocoolab, TrueClicks, YouSpot, Fluenta, VarynForge, Saaskly, Fruit Stand, GoBuy, Create Prints, Tessryx, VeriRoute, Alien Probe, agent.social, studiofromthesea, Prove AI, pulse-verity, dxpert UNS tools.
