Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 15 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability66
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 2746 tokens (~183/item across 15 items; 15 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 15 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 16 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the DepthFeed MCP server?
DepthFeed is a hosted endpoint at https://api.depthfeed.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

backtest_paths ~210
Mid-price path per Polymarket market for backtesting, resampled to a fixed interval and bounded to each market's own lifetime so post-settlement books cannot leak in as risk-free fills. Returns {interval_seconds, markets:{<market_id>:{points:[[ts_ms, price_up, coin_price], …]}}} — up to 1000 points per market. Pass 1 to 50 market ids from polymarket_search_markets. History is bounded by the plan window and the interval floor by plan; both fail closed rather than silently coarsening.
| Name | Type | Req | Description |
|---|---|---|---|
| coin | string | – | Crypto asset. Every account plan reaches all seven; only the keyless demo surface is BTC-only. |
| ids | string | yes | Comma-separated Polymarket market ids, 1 to 50, from polymarket_search_markets. |
| interval | integer | – | Resample interval in seconds (default 60). The floor is set by plan; a finer value is refused, not rounded. |
No output schema declared.
No examples provided.
bars ~335
OHLCV price bars for US equities and ETFs, Binance spot pairs, and perpetual futures. One minute is the finest resolution; 5Min, 15Min, 1Hour and 1Day are rolled up from it and say so with `derived`. Spell a crypto pair the way the venue does (BTCUSDT, not BTC) and a perpetual with a .P suffix (BTCUSDT.P) — spot and perp are different instruments at different prices. BTCU, ETHU and WLDU are each both a US ETF and a Binance pair, and resolve to the equity — pass venue=binance to reach the pair instead. Optional `venue` selects the market explicitly: us-equities, binance (spot) or binance-futures (perpetuals). Bounded by the same plan history window as every other read (403 HISTORY_LIMIT_EXCEEDED past it); the plan also sets how many symbols one request may carry.
| Name | Type | Req | Description |
|---|---|---|---|
| end_time | string | – | End of time as ms-epoch or ISO-8601. History is clamped to your plan's window. |
| start_time | string | – | Start of time as ms-epoch or ISO-8601. History is clamped to your plan's window. |
| symbols | string | yes | Comma-separated symbols, e.g. "AAPL,BTCUSDT,BTCUSDT.P". 3 per request on Explorer, 8 Quant, 16 Research, 32 Desk. |
| timeframe | string | – | 1Min (default), 5Min, 15Min, 1Hour or 1Day. |
No output schema declared.
No examples provided.
kalshi_get_candles ~241
Hourly OHLC candles (yes bid, yes ask, traded price) plus volume and open interest for a Kalshi market. This is the only history that exists for non-crypto Kalshi markets — Kalshi serves no historical order book — and it reaches back up to a year, far past the order-book capture. `price` is null in periods with no trade. Every account plan; history is bounded by your plan window.
| Name | Type | Req | Description |
|---|---|---|---|

What is the DepthFeed MCP server?
DepthFeed is an MCP server listed in the public MCP registry as com.depthfeed/depthfeed. Order-book depth & history for Polymarket, Kalshi & Limitless. Keyless demo, key for full access. This page covers its hosted endpoint (https://api.depthfeed.com/mcp).
Is the DepthFeed MCP server safe to use?
DepthFeed scores 77 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the DepthFeed MCP server expose?
DepthFeed exposes 15 tools: polymarket_all_markets, polymarket_search_markets, polymarket_get_market, polymarket_get_snapshots, kalshi_search_markets, and 10 more. Their descriptions and schemas cost roughly 2,546 tokens of context every time the server is loaded.
Does the DepthFeed MCP server require authentication?
No. We connected to DepthFeed without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the DepthFeed MCP server still maintained?
DepthFeed is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
