MCP Server Discovery - October 16, 2026 (Midday Sweep)

Midday sweep about 6 hours after the October 16 night sweep: the mcp.so /feed (30 server links via the direct TanStack fetch), mcpservers.org /all pages 1-5 through the r.jina.ai reader proxy (page 1, newest-first, matched the night cohort slug for slug, so the surface showed no new listings), the fresh chatmcp/mcpso issue window #5508-#5535 (28 numbers, all live), and the twelve-sitemap canonical window check (r124 to r126: 15,835 EN server URLs; zero additions and zero removals), with vendor docs and live endpoint probes for every candidate. Two new business-relevant entries, each catalogued with a guide: a hosted omnichannel business inbox, and the GB standard steel section reference.

New Servers Catalogued

Server	Category	What it does
DialogBrain MCP	Business Operations	A customer inbox exposed as MCP tools: one URL turns a business workspace into tools the assistant can call, so it reads and answers WhatsApp, Telegram, Instagram, email and SMS conversations, looks up the contacts behind them, places calls and works with transcripts, reads and updates the task board, uses the workspace knowledge base, and manages the workspace's agents and calendar. One connection is scoped to one workspace and the assistant runs under the same permissions the company's own agents use. Hosted remote server (api.dialogbrain.com/mcp/) with OAuth 2.1, PKCE and dynamic client registration; a bundled Claude Code plugin adds six skills
FindingSteel MCP	Manufacturing & Industrial	The Chinese GB standard steel section reference and calculator: search 143 GB/T section records by category or keyword, look up one exact designation for its section properties (A, Ix, Iy, Wx, Wy, ix, iy and kg/m), compute a welded I-section or box section from plate dimensions, calculate theoretical weight for plate, round, square, flat, hexagon, octagon, rebar and pipe shapes, and read the built-in material density table.

Sources

• mcp.so /feed (30 server links, direct TanStack fetch; the newest cards past the night capture were Singularis, InvestJournal, UGCraft, ImgAI, Jev AI Developer API, Loreform, Sign PDF, a2agent, KelvinAI, OpenGame, Wan 3.0 AI Video Generator, Ricebowl AI, AI Hairstyle Changer, MenuForma and Photo Mosaic, with Postdom, the Korea & Asia Everyday Calculators (kwhmate), SoChain, Radikabunavi, ProLevelMax, Default Privacy, Soundza, Social Growth Engineers, Shortimize, App Store Tracker, Layro, MySSAgent Social Security Claiming Estimator, InstaBids, The Living Bread and Logimu Shopping carrying prior dispositions)
• mcpservers.org /all pages 1-5 via the r.jina.ai reader proxy (139 slugs; page 1, newest-first, carried the same 30 servers as the night capture, so the surface showed no new listings; pages 2-5 carried the domain-style slug cohort and prior dispositions)
• Fresh chatmcp/mcpso issue window #5508-#5535 (28 numbers, all live)
• Twelve-sitemap canonical window check (r124 to r126: 15,835 EN server URLs after locale-prefix stripping; zero additions and zero removals)
• Vendor docs and live endpoint probes for every candidate (DialogBrain: POST initialize to api.dialogbrain.com/mcp/ returns 401 with a live endpoint, and both /.well-known/oauth-protected-resource and /.well-known/oauth-authorization-server resolve 200 - the resource is named, and the authorize, token and dynamic-registration endpoints are published with PKCE S256; registry com.dialogbrain/dialogbrain v1.0.0 resolves, the per-client guide is live and the six-skill plugin is published. FindingSteel: keyless initialize returns 200 as findingsteel-steel-sections v0.1.0 with a tools capability block and tools/list returns all seven tools; the vendor llms.txt and the MIT repo are live)

Also Identified (Not Catalogued)

mcp.so /feed (30 links): the fresh cards were consumer and creative utilities - Singularis, InvestJournal, UGCraft, ImgAI, Jev AI Developer API, Loreform, Sign PDF, a2agent, KelvinAI, OpenGame - AI Game Agent, Wan 3.0 AI Video Generator, Ricebowl AI, AI Hairstyle Changer, MenuForma and Photo Mosaic & AI Collage Maker - and each resolved to a class hold (social-publishing saturation per Postdom, PostSider, PostBase, Pith and PostPlanify; crypto class; consumer and design utilities; media-generation class). Postdom and the Korea & Asia Everyday Calculators (kwhmate) carried their October 15 and October 16 night dispositions, as did SoChain, Radikabunavi, ProLevelMax, Default Privacy, Soundza, Social Growth Engineers, Shortimize, App Store Tracker, Layro, MySSAgent Social Security Claiming Estimator, InstaBids, The Living Bread and Logimu Shopping.

chatmcp/mcpso issue window #5508-#5535 (28 numbers), all held beyond the two catalogued entries: PayAPI Market (a free read-only search over 358 pay-per-call x402 APIs; the agent-payments class is dense per steward-mcp, Mekler and agpay) held; dekimu-mcp (mint and verify offline action receipts and run reproducible GDPR checks, local-first with no telemetry; business-relevant, but held because the documented npx @dekimuhq/dekimu-mcp install does not resolve yet - the npm package returns Not found, so the repo runs from source only and it is a re-check once npm publishes) held; MCP Harbor Search (search a 1,400-server directory from inside an MCP client; the meta-index class per the Agent Data Co, AgentAtlas and WealthMCP holds) held; GridPin (offline geocoding and reverse geocoding; data utility) held; AyHire (hire engineers by what they shipped on GitHub; the hiring and recruiting classes are dense per Hilead, Metix AI and the mambabuilt job-change family) held; CADProps (CAD inspection, 3D previews and conversion; design and CAD utility) held; Autonomad (travel search with an agent-earning mode) and Adaga Network (direct hotel booking federation) held (consumer travel class per google-hotels-mcp); PostWharf (schedule and publish to nine networks; social-publishing class at saturation) held; Cloud for Bots, Sandbox Timer, AI Gateway MCP and Paw Pulse held (agent-infrastructure and dev-utility classes per AegisCore, Agentguard and the CloudCorpRecords fleet); Automaton Onchain Tools, Bitrovas PSBT-Check and wealth-agent held (crypto and x402 classes); Context Window Supply (merch commerce), Fair Random and Lottery Numbers (novelty), OSWright (Windows desktop automation; browser-automation class), BotMash (a public wall where AI bots post; novelty), Prox (nearby local shops), SendFaxFast (fax utility) and Pidgeon (mailboxes for agents; the agent-email class is saturated per Voidmail, Poofbox and Supermailbox) held; the two docs-only entries (#5534 Automaton Onchain Tools and #5529 BountyRadar featured-directory PRs) carry no new server.

mcpservers.org /all pages 1-5 (139 slugs): page 1 (newest-first) matched the night cohort slug for slug (RockFlow MCP, Marketing MCP by Honeyfield, Soundza, Social Growth Engineers, Shortimize, DBine, App Store Review Intelligence, searxNcrawl, CloneKit, Ganjoor, The Bureau of Lost Context, HiveHall, Phở Research Tools, Kantan, Flavors Engine, SAGA, Yadulink, NullClear, Zinc, CourtlyGo, patlas, VideoBGRemover, Threshold, Hugging Bay, Casafari, Heard, MainWP, Browser Use, Trudex), so no new listings entered the surface this cycle. Pages 2-5 carried the domain-style slug cohort rather than fresh listings - the rapidapi-com utility kit (calkit, dockit, domainkit, fraudkit, geoip, imagekit, llmkit, phonekit, qrkit, textkit, validkit, webkit), the wrpbr utility suite (okfindex, radar-cnpj, pageaudit, hookpulse, commsharbor, agentalog, editalmd, pontofato), the profitpather shells (days, duty, ship, store) and the nikhonit ScraperSocial skills tree - alongside prior dispositions, none of which resolved to a new business-relevant server. Narrower slices were evaluated and held: SourcetoMCP (connect agents to Google Ads, Search Console, Analytics, Sheets, TikTok, Pinterest, Reddit, Bing Webmaster, Ahrefs and PostHog; the cross-channel marketing-connector class is dense per the catalogued Blend MCP, Get Ads and Marketing MCP entries) held; Billr (53 invoice, time and expense tools) and Dunn (read-only invoice tools) held (the invoicing and AR classes per the catalogued Paidnice and TWOCENTS entries); Metix AI (recruiting search over 900M people and 30M companies) held (hiring class); RowSafe (PostgreSQL backup health and restore points; dev-infrastructure class) held; SalCrate Oracle (pay-per-call web intelligence; x402 class); RealtyCrawl (source-linked real-estate observations; the property-data class per PremiumPin and CarDossier); Space (shared persistent agent memory; the agent-memory class per Tephra); UnderIndex (niche fashion records; novelty) and Quarterly Tax Calculator (consumer finance calculator) held. The canonical window check (r124 to r126: zero additions, zero removals) confirmed the sitemap itself was unchanged.

CorpusIQ Listing State

Checked this cycle (unchanged):

• mcpservers.org: LISTED (/servers/corpusiq-io serves the CorpusIQ page, HTTP 200 through the reader proxy)
• glama.ai: LISTED (glama.ai/mcp/connectors/io.corpusiq/multi-source-mcp returns 200; the older /mcp/servers/... path form 404s)
• smithery: LISTED (registry query returns Cprusiq as the first result, unlisted=false)
• mcp.so: NOT LISTED (four direct slug probes - /server/corpusiq, /server/corpusiq-io, /server/corpusiq-mcp, /server/io.corpusiq - all 404; the account quarantine holds, no resubmit)

No changes to the CorpusIQ listing state this cycle. New MCP-directory candidates surfaced by a GitHub search were all low-signal (single-digit or zero stars) and were not submitted.
