fix(financial-analysis): repair malformed .mcp.json that silently drops all 12 connectors

[knym]

Problem

plugins/vertical-plugins/financial-analysis/.mcp.json is not valid JSON. The egnyte entry is missing its trailing comma and the box object is never closed:

    "egnyte": {
      "type": "http",
      "url": "https://mcp-server.egnyte.com/mcp"
    }            <-- missing comma
    "box": {
      "type": "http",
      "url": "https://mcp.box.com"
  }              <-- "box" never closed
}

python3 -c "import json; json.load(open(...))" fails with Expecting ',' delimiter: line 47 column 5. This is the only invalid JSON file under plugins/.

Impact

All 12 data connectors are silently dropped. Installation succeeds with no error or warning, so a user who has paid for FactSet / PitchBook / Moody's / LSEG / S&P Global / Morningstar / Daloopa access has no way to tell the connectors were never registered — the skills just behave as if no data source exists.

Verified by installing the plugin from an otherwise identical local marketplace, with and without this fix:

Version	Install result	claude plugin details reports
current main	success, no warning	MCP servers (0)
with this fix	success	MCP servers (12) daloopa, morningstar, sp-global, factset, moodys, mtnewswire, aiera, lseg, pitchbook, chronograph, egnyte, box

Reproduce on current main:

claude plugin marketplace add anthropics/financial-services
claude plugin install financial-analysis@claude-for-financial-services
claude plugin details financial-analysis@claude-for-financial-services   # MCP servers (0)

Fix

Add the missing comma and close the box object. Two lines, no behavior change beyond the connectors loading as intended.

Why CI did not catch this

.github/workflows/plugin-validate.yml runs claude plugin validate <plugin_dir>, which only validates .claude-plugin/plugin.json — .mcp.json is not checked. On current main:

$ claude plugin validate plugins/vertical-plugins/financial-analysis
Validating plugin manifest: .../.claude-plugin/plugin.json
✔ Validation passed

Not addressed in this PR to keep it minimal, but adding a json.load pass over every plugins/**/.mcp.json to the validate workflow would prevent a recurrence.
