MCP Server Discovery - October 10, 2026 (Evening Sweep)

Evening sweep over 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 (the fresh cohort diffed against the October 10 r99 canonical capture: 100 net-new server URLs across the twelve sitemaps, zero removals, after locale-prefix normalization), and the fresh chatmcp/mcpso issue window #5083-#5108, with vendor docs and live endpoint probes for every candidate. Five new business-relevant entries, each catalogued with a guide: agent action authorization with recorded decisions, a dataset marketplace with keyless discovery, IRS e-filing reads, freight carrier compliance checks against FMCSA records, and Medicare policy and prior-auth research.

New Servers Catalogued

Server	Category	What it does
Vulnify MCP	Security & Governance	Runtime authorization for agent actions: ALLOW, REVIEW or BLOCK decisions from stored policies, policies as code you can list and test, and recorded security events and audit entries for decide_action and check_mcp_tool_call - 7 tools, 5 in an OAuth session with scoped consent and 2 behind an API key; REVIEW is resolved by a person, and no approve tool exists
DataBazaar MCP	Data & Analytics	The marketplace where agents buy data: search datasets with filters, inspect about-50-row samples with schema and quality scores, get a checkout URL for one-click human purchase, and work with listings and bounties - 3 keyless public tools on api.databazaar.io/mcp/public, 27 tools and 5 resources on the authenticated surface
BoomTax MCP	Finance & Accounting	Read-only access to a company's IRS e-filing: filings by year, form type and status, e-file request and response timelines, error messages, payer summaries with masked TINs, and current filing types - 10 read-only tools that cannot create, edit, delete or submit filings
Carrier Ledger MCP	Logistics & Transportation	FMCSA carrier checks before booking or paying: a single carrier by USDOT or MC, a list of up to 25, and recent suspension notices with effective dates - authority, insurance and bond, red flags with the FMCSA dataset cited per fact; the account product adds contact-change monitoring and dated per-load records
Backwork MCP	Healthcare Operations	Medicare and payer policy research from the assistant: coverage lookups, MAC jurisdiction comparisons, claim validation with denial risk, prior-auth checklists, commercial drug formulary evidence, and policy-change review - 8 workflow tools with numbered citations per fact, MCP Apps cards, and a Claude Code plugin with four clinical skills
