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 / MCP Access. 3. Generate a key (depth4_mcp_… prefix, up to 3 active keys). Copy it once. 4. In Cursor or another remote MCP client, set the URL to https://depth4.com/api/mcp and header Authorization: Bearer <your key>. 5. Optional: use the local stdio server from /docs/mcp. 6. Optional (Insider+): set Industry focus tags on Account to filter digest and feed scope to your sectors. Keys are read-only and follow your plan. Revoke a key from Account if it leaks.
Main MCP tools
| Tool | What it returns |
|---|---|
| depth4_list_signals | Fleet or filtered SIGNALS. Each row has signal_state (RISING, FALLING, or MIXED), as_of, and latest theses |
| depth4_get_signal | One symbol (XAUUSD, BTC, oil). signal_state, as_of timestamp, and latest theses. Pro adds book alignment |
| 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) |
Technical reference
Remote URL, Bearer header, tool list, and the signal_state field live at /docs/mcp. There is no OAuth step — paste the key into the client.
Revoke compromised keys immediately from Account — plaintext is shown only once at creation.
