Agent / MCP access
Connect Cursor, Claude Code, or LangChain to DEPTH4 signals, theses, and digests.
What it is
DEPTH4 exposes a Model Context Protocol (MCP) server so your coding agent can read live signals, thesis cascades, feed updates, and daily digests — the same intelligence loop as the web app, structured for automation. Personal agent use only; no resale or redistribution.
Who gets access
| Plan | MCP access |
|---|---|
| Free | — |
| Insider | Fleet-wide signals, theses, feed, list/get tools, daily digest (no entry_timing on digest) |
| Pro | Full toolkit — portfolio/watchlist/book scope, copilot context, entry_timing on digest, entry_timing_detail on get_signal |
Get started
1. Upgrade to Insider or Pro. 2. Open Account (/account) → Agent access. 3. Create an API key (depth4_mcp_… prefix, up to 3 active keys). 4. Follow setup at /docs/mcp for Cursor, Claude SDK, or LangChain. 5. Optional (Insider+): set Industry focus tags on Account to filter digest and feed scope to your sectors.
Main MCP tools
| Tool | What it returns |
|---|---|
| depth4_list_signals | Fleet or filtered signal list with direction, blind spot, tradability, entry_timing state |
| depth4_get_signal | One symbol — Insider+; Pro adds book alignment and entry_timing_detail |
| depth4_get_thesis | Full D1–D4 thesis cascade by slug |
| depth4_get_feed_updates | Recent feed items — fleet (Insider) or watchlist/book (Pro) |
| depth4_get_daily_digest | Curated digest — Pro can scope to portfolio and includes entry_timing |
| depth4_get_copilot_context | Macro or full copilot context for a symbol |
| depth4_get_account_scope | Pro — your watchlist, book, and industry tags |
Industry focus (Insider+)
On Account → Industry focus, add up to 10 tags (e.g. energy, rates, china). Saved tags filter MCP feed and digest defaults when you do not pass an explicit industry parameter. Tags are stored on your account, not in the API key.
Digest and feed scope (Pro)
| Scope | Signals included |
|---|---|
| fleet | All monitored assets (default Insider) |
| watchlist | Starred symbols only |
| book | Symbols in your position book |
| portfolio | Union of watchlist + book (Pro default when set) |
