Add device sweep to resolve Claude connector UUIDs#217
Conversation
Fetch the backend's unresolved-UUID list, match each against the local Claude session files (Claude Code + CoWork folders), and report the resolved name + tools back via the single-server scan endpoint with the originating UUID. Only UUIDs the backend asked for are sent; HTTP via curl per the Zscaler constraint.

When a requested UUID is resolved, this branch also sends the local session url to the control plane. The flow is described as sending only the requested UUID plus the real name and tools, so a normal successful sweep can disclose private connector endpoints or stale local URLs that the backend did not ask for.

When the same UUID appears in more than one scanned session file, this path keeps the first name and URL but unions tools from every later entry. A stale or conflicting file can produce one report with connector A's identity and connector B's tools, causing the backend to fold the unresolved UUID into the wrong grouped connector metadata.

When curl fails before a valid HTTP response, _run_curl ignores the non-zero exit code and stderr. Proxy, DNS, TLS, and timeout failures can be reported as an empty status or http 000, leaving operators without the real reason the sweep could not fetch or report UUIDs.

UUID strings not normalized
Medium Severity
Unresolved UUIDs from the API are matched against local session keys with plain string equality, while local UUIDs are only stripped. Values that differ by letter case or extra whitespace on one side never intersect, so the sweep can exit with zero local matches even when session files contain the connector.

Duplicate UUID keeps first name
Medium Severity
When the same connector UUID appears in multiple local_*.json files, merge logic unions tools but never replaces an existing display name if the first stored entry already has one. A stale name from an earlier session file can be reported while a later file has the current name, producing the wrong claude-connector fingerprint on the control plane.

🛡️ Automated Security Review (consensus)
2 findings — 1 high-confidence, 1 to triage. Reviewers: Cursor, Claude, Semgrep, Gitleaks.
🔴 HIGH — Local connector url sent beyond documented device scope
scripts/coding_discovery_tools/sweep_connectors.py:154-155 (also report_connector ~143-165)
Impact: Resolved sweeps POST the session file's url to the control plane even though the PR contract and module doc state only {name, tools, connector_uuid} leave the device — expanding disclosure of private MCP endpoint metadata the backend never requested.
Fix: Remove url from the report payload to match the documented contract, or explicitly extend the PR/backend scope and treat url as sensitive data end-to-end.

🟡 TRIAGE — Conflicting duplicate UUIDs merged without identity checks
scripts/coding_discovery_tools/sweep_connectors.py:86-95
Impact: When the same UUID appears in multiple session files, merge logic keeps the first name/URL and unions tools from later entries — a stale or conflicting file can report connector A's identity with connector B's tools, folding the UUID into the wrong grouped fingerprint on the control plane.
Fix: Skip or split on name/URL mismatches before unioning tools (e.g., only merge when name and URL agree, or prefer the newest session file).

What
Adds a device-side sweep that resolves bare Claude connector UUIDs to their real names so the control plane can group/policy them. Companion backend change: ai-gateway-data PR (
vv/backfill-uuid-mcp-connectors).Claude desktop OAuth remote connectors are named by a per-registration UUID at runtime. The real display name only exists in the local Claude session files on the device — the backend can't resolve it alone.
How (

Note
Low Risk
Adds an opt-in CLI script with scoped outbound reporting (only backend-listed UUIDs); no changes to existing discovery flows or shared libraries.
Overview
Adds
sweep_connectors.py, a standalone device-side script that backfills bare Claude OAuth connector UUIDs with human-readable names and tool lists the control plane cannot infer without local Claude session data.The flow fetches an opaque list from
GET /api/v1/ai-tools/unresolved-connector-uuids/, maps requested UUIDs againstremoteMcpServersConfigin localclaude-code-sessionsandlocal-agent-mode-sessionsJSON (with cross-folder de-dupe and tool union), thenPOSTs only matched UUIDs to/api/v1/ai-tools/mcp-server-scan/withconnector_uuid,claude-connectorscope, name, tools, and optional URL. HTTP is implemented viacurl(stdin config + Bearer auth) rather thanurllib, consistent with other discovery scripts and Zscaler constraints.Not wired into the main discovery scan cycle in this PR; no automated tests included.

Greptile Summary
This PR adds a standalone sweep for resolving Claude connector UUIDs. The main changes are:
Confidence Score: 1/5
The new sweep can send extra local connector metadata and can merge conflicting session records into one backend report.
urlfrom local session files.scripts/coding_discovery_tools/sweep_connectors.py
Security Review
The sweep sends the local connector URL from session files to the control plane, which expands the device metadata disclosed beyond the stated UUID/name/tools payload.
