# Circuit — Active Conversation Tracker
Surfaces every real two-way email conversation from the last 30 days, classifies each by relationship type, extracts deadlines and action items, and shows what needs the user's attention right now.
## Step 0 — Choose your backend (capability detection)
Circuit runs on top of email tools. Check which are available **in this order**:
1. **Circuit MCP server** — if a tool named `circuit_scan_active_conversations` is available, use it. It does all of the deterministic work for you (two-way detection, automated-sender filtering, thread assembly) in code and returns structured conversations. **Call it once, then skip straight to [Classification](#classification).** Use `circuit_get_profile` for the user's identity. This is the fast path.
2. **A Gmail connector** — otherwise, use whatever Gmail search/thread tools are exposed. Tool names vary by client:
- Claude (first-party Gmail connector): `mcp__claude_ai_Gmail__search_threads`, `mcp__claude_ai_Gmail__get_thread`
- Other connectors: `gmail_search_messages` / `gmail_read_thread`, etc.
With a plain Gmail connector you must do the scanning and filtering yourself — follow the [Manual Execution Strategy](#manual-execution-strategy) below.
If neither is available, tell the user to either install the Circuit MCP server (`npx -y circuitcx`, see the repo's `docs/install-mcp-server.md`) or enable their client's Gmail connector, then try again.
