MCP Server Discovery - October 18, 2026 (Night Sweep)

Night sweep about 47 hours after the October 16 midday sweep, the longest gap of the month. Sources: the mcp.so /feed (30 server links via the direct TanStack fetch, 27 of them new to the ledger), mcpservers.org /all pages 1-5 through the r.jina.ai reader proxy (150 slugs, page 1 churned completely past the October 16 cohort), a fresh twelve-sitemap canonical refresh (r127: 16,280 EN server URLs after locale and fragment normalisation, 487 additions and 42 removals against the r126 capture, with 310 of those additions landing since the October 17 capture), and the fresh chatmcp/mcpso issue window #5666-#5712 (45 numbers, all live), with vendor docs and live endpoint probes for every candidate. Four new business-relevant entries, each catalogued with a guide: a supplier price-drift comparator for purchasing, a keyless data-protection deadline server, pre-dial screening against the UK and Australian do-not-call registers, and demand discovery across four developer communities, the last of which came from a separate pass over the same 310 additions after the first three were catalogued and had not been dispositioned by the earlier holds.

New Servers Catalogued

Server	Category	What it does
PayloadPier MCP	Procurement / Finance	Supplier price-list comparison by exact SKU over Streamable HTTP at payloadpier.com/api/mcp. compare_supplier_prices takes an idempotent operation_id plus old_rows and new_rows snapshots and returns the unit-cost change, catching the increase hidden behind an unchanged case price when a pack size or minimum order changes, with the gross-margin impact of the delta. Three account and referral tools sit beside it. One included comparison unit, then $0.25 prepaid; scoped API key in the Authorization header. It is a comparator, not a supplier catalogue: you supply the rows.
Double AIgents DSAR MCP	Compliance / Legal Operations	Free keyless read-only server at www.doubleaigents.com/api/mcp for UK, EU/EEA and Swiss data protection work. Ten tools: the DSAR response deadline with the rule that applies and the extension position, the personal data breach notification clock, breach triage, acknowledgement, extension and clarification letters, DSAR request scoping, DPIA and EU AI Act screening, UK HR retention periods and a DSAR search checklist. Every tool is labelled general information rather than legal advice, and nothing about a live request is stored between calls.
TPSClear MCP	Sales Operations / Compliance	Pre-dial screening at tpsclear.co.uk/api/mcp. screen_numbers checks up to 1,000 numbers per call against the UK TPS and CTPS registers and returns one of six states per number (clean, tps-listed, ctps-listed, unknown, suppressed, consented), with an optional campaign_ref kept on the audit record; wash_au_numbers checks the ACMA Do Not Call Register; check_dead_numbers runs HLR lookups for live, switched off or dead mobiles; get_account, set_company_name and buy_credits handle the account, and the top-up is returned as a Stripe Checkout link a person pays. Test keys return UK fixtures free. Plans from 95 GBP per month ex VAT for 2,500 checks per 28 days, then 15 GBP per 1,000.
AskHound MCP	Marketing / Demand Discovery	Demand discovery across Hacker News, Stack Exchange, Bluesky and GitHub: search the phrase that matches what you sell with a recency window, context words, negative terms and an intent floor, run saved packs that return only matches new since the last run, and record each conversation as replied, skipped or seen. Local stdio server (five tools, all four sources), a stateless remote endpoint at askhound.haullabs.dev/api/mcp (four tools, Stack Exchange and Bluesky only) and a CLI with search, queries --competitor, pack save, pack run and mark. Public APIs only, GITHUB_TOKEN raising search from 10 to 30 requests a minute, MIT source, one anonymous ping a day with an opt-out, reply_policy encoding disclosure-first replying, free to run locally

Result

Catalog moved from 934 servers (+820 guides) to 938 servers (+824 guides). The first three entries were catalogued in this sweep; the fourth, AskHound, came from a separate late pass over the same 310 additions and had not been dispositioned by any earlier hold.
