fix(catalog): give HTTP connectors a real tool source (openApiUrl or MCP)

[neubig]

Summary

Closes #366.

44 catalog connectors were defined as provider: "http" with a hand-authored
defaultTool and no openApiUrl on their first connection option. The
defaultTool is a single hardcoded request template that only ever exposes
one tool per provider, under-represents the API, and can drift from the real
API surface. This PR gives every affected connector a real, machine-readable
tool source and removes the obsolete defaultTool.

For each affected connector, the first connection option now either:

1. keeps provider: "http" and gains an http.openApiUrl pointing at the
   provider's published OpenAPI / Google Discovery / API-spec document so the
   full tool set can be generated from the schema (preferred when the provider
   publishes a machine-readable spec), or
2. migrates to provider: "mcp" with a transport.url pointing at the
   provider's official hosted MCP server (Streamable HTTP) so tools are
   discovered live via tools/list (used when the provider has an official
   hosted MCP server and no convenient OpenAPI document).

In both cases the now-obsolete http.defaultTool field is removed.

github is handled separately: its mcp connection option carried a dead
defaultTool (MCP discovers tools live, so the field was harmless but
inconsistent). That field is removed; github's provider/transport are
unchanged.

notion and elevenlabs already had an openApiUrl and are not touched.

Only integrations/catalog/*.json files are modified (40 files). All other
fields (OAuth URLs, scopes, auth strategy, categories, logos, keywords, etc.)
are preserved. JSON formatting (2-space indent, trailing newline) matches the
existing files.

Option 2 — migrated to provider: "mcp" (official hosted MCP server)

Connector	MCP server URL
airtable	https://mcp.airtable.com/mcp
clickup	https://mcp.clickup.com/mcp
dropbox	https://mcp.dropbox.com/mcp

monday	https://mcp.monday.com/mcp
posthog	https://mcp.posthog.com/mcp
supabase	https://mcp.supabase.com/mcp

All MCP URLs were verified to respond with 401/405 (i.e. a live
authenticated MCP endpoint) rather than a 404/redirect, and each is documented
by the provider as their official hosted MCP server (Streamable HTTP).

github

Only the dead defaultTool was removed from its mcp option.
provider/transport/http.apiBaseUrl are unchanged.

Could not resolve (left unchanged — need a human)

These connectors publish no public machine-readable OpenAPI and have no
official hosted MCP server. Per the issue instructions they are left
unchanged (their defaultTool remains) and listed here for a human to decide:

Connector	Why unresolved
quickbooks	Intuit publishes no machine-readable OpenAPI for the QuickBooks V3 REST API (the developer portal is an SPA returning HTML); no official hosted MCP server exists.
salesforce	Salesforce's hosted MCP (Agentforce) is org-specific — the URL is configured per-org in Setup and there is no single public endpoint; no public OpenAPI for the Salesforce REST API.
servicenow	ServiceNow OpenAPI is only exportable from within a given instance (instance-specific URLs); no public hosted spec or official MCP server.
shopify	Shopify's only official MCP offering is the stdio @shopify/dev-mcp (docs search, not the Admin REST API); no clean public OpenAPI for the Admin REST API and no hosted HTTP MCP server.
zendesk	mcp.zendesk.com redirects to the help center (no MCP); Zendesk publishes no public machine-readable OpenAPI spec for its REST API.

Verification

A Python scan (/tmp/verify_catalog_366.py, not committed) over
integrations/catalog/*.json asserts:

• No http connection option has a defaultTool without an openApiUrl
  (except the 5 unresolved connectors above, which are intentionally left
  unchanged and listed).
• github's mcp option has no defaultTool.
• Every formerly-affected connector either has an openApiUrl or is
  provider: "mcp" with a transport.url.

Result:

PASS
Remaining defaultTool entries in catalog: ['notion#0', 'quickbooks#0', 'salesforce#0', 'servicenow#0', 'shopify#0', 'zendesk#0']
  notion#0 is expected (notion already had openApiUrl, unchanged).
  Unresolved (left unchanged, listed in PR): ['quickbooks', 'salesforce', 'servicenow', 'shopify', 'zendesk']
Affected connectors resolved: 39

(notion#0 keeps its defaultTool because it already had an openApiUrl and
is explicitly out of scope per the issue.)

The repo's existing test suite passes unchanged (no test referenced
defaultTool):

uv run --group test python -m pytest -q  →  364 passed

git status -sb shows only the 40 catalog JSON files modified.
