Update the small-business plugin: 44 skills across finance, sales,
marketing, customers, operations and hiring, shared reference files,
more connectors, and a rewritten README. The marketplace description
now matches plugin.json.
The ms365 / microsoft-365 entries ship M365 as a manual type:http MCP
server. That auth path cannot succeed: the M365 server's OAuth client
registration only permits the claude.ai callback, so any client-initiated
OAuth flow (localhost or claude:// redirect) is rejected by the identity
provider before the consent screen ever shows (AADSTS50011).
Users connect Microsoft 365 through the claude.ai Connectors directory
instead, which uses the registered callback and works. Plugin skills
reference tools via ~~category placeholders (see CONNECTORS.md), not the
ms365 server key, so no content changes are needed.
Bumps each touched plugin's version so the update distributes to
existing installs.

The Check MCP URLs workflow (after the connection-failure probe fix in
this PR's parent) surfaced four endpoints that fail every connection:
- mcp.deepsense.ai does not resolve in DNS at all. The biorxiv, chembl,
and clinical_trials servers were rehosted under
hcls.mcp.claude.com (Anthropic MCP directory entries dated
2026-01-07). Paths are unchanged; only the host moved. All three
return a complete MCP initialize response with no auth.
- mcp.paypal.com/mcp returns 404 at every path. PayPal's live endpoint
is /sse (SSE transport, not streamable HTTP) and returns 401 with
WWW-Authenticate: Bearer realm="OAuth" — alive, OAuth required.
Their docs claim /http for streamable transport but it returns 404
today. Type changed http -> sse to match the actual transport.
Anyone with the bio-research or small-business bundle installed gets
connect failures on every agent spawn until this lands.
PayPal migrated their MCP endpoint from Streamable HTTP at `/mcp` to
SSE at `/sse`. Old URL now returns 404 ("gone"); new URL returns
401 (alive, needs auth) and advertises full OAuth discovery including
DCR at /.well-known/oauth-authorization-server.
Matches the repoint pattern from #238 (datadog, apollo, outreach
moved paths; only servicenow was truly dead) and the type:http +
/sse convention already used by `square` in this same file.
Unblocks the "Check MCP URLs" liveness workflow (#236) which has
been failing every open PR on the paypal 404.

- Add 'Tone for connectors' section to SKILL.md: describe what Claude can
do once connected, not what the platform sells
- Rework step 2 to name functions first, check what the owner uses, then
branch on supported vs unsupported tools
- Add Branch B (unsupported tool) example to happy-path.md
- Add 'pitching the platform instead of the capability' gotcha
Pre-built small business workflows: payroll planning, month-end close,
weekly briefs, growth campaigns, contract review, CRM hygiene, and more.

other small-business tools.
- Add small-business/ with skills, plugin.json, and README
- Register plugin in .claude-plugin/marketplace.json
