ApexTick MCP Server

Turn Claude, Cursor, Windsurf, OpenCode or any Model Context Protocol client into a market analyst with five native ApexTick tools.

The ApexTick MCP server exposes read-only market intelligence tools over the Model Context Protocol. Your assistant calls them during a chat turn, and the tools run server-side behind the API gateway and return compact, context-efficient answers.

#Connecting

There are two ways to connect, depending on what your client supports:

Both modes use the same hosted server, the same tools and the same plan limits. The hosted endpoint is stateless: it doesn't use Mcp-Session-Id, and every request is authorized against your plan, so an upgrade takes effect on the very next tool call.

#Client configuration

Set your key once in your shell profile, then copy the block for your client:

export APEXTICK_API_KEY="dk_your_key_here"

#Claude Desktop

Claude Desktop's config file launches local stdio servers, so use the mcp-remote bridge (requires Node.js). Open Settings → Developer → Edit Config and add:

{
  "mcpServers": {
    "apextick": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote@latest",
        "https://api.apextick.com/mcp",
        "--header",
        "apikey:${APEXTICK_API_KEY}"
      ],
      "env": {
        "APEXTICK_API_KEY": "dk_your_key_here"
      }
    }
  }
}

Fully quit and reopen Claude Desktop after saving. On macOS the file is ~/Library/Application Support/Claude/claude_desktop_config.json; on Windows it's %APPDATA%\Claude\claude_desktop_config.json.

#Claude Code

claude mcp add --transport http apextick https://api.apextick.com/mcp \
  --header "apikey: $APEXTICK_API_KEY"

#Cursor

Add to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project):

{
  "mcpServers": {
    "apextick": {
      "url": "https://api.apextick.com/mcp",
      "headers": {
        "apikey": "${env:APEXTICK_API_KEY}"
      }
    }
  }
}

#Windsurf

Add to ~/.codeium/windsurf/mcp_config.json, then refresh the MCP list in Cascade:

{
  "mcpServers": {
    "apextick": {
      "serverUrl": "https://api.apextick.com/mcp",
      "headers": {
        "apikey": "${env:APEXTICK_API_KEY}"
      }
    }
  }
}

#OpenCode

Add to opencode.json in your project or global config. oauth: false tells OpenCode the server uses an API key:

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "apextick": {
      "type": "remote",
      "url": "https://api.apextick.com/mcp",
      "oauth": false,
      "headers": {
        "apikey": "{env:APEXTICK_API_KEY}"
      }
    }
  }
}

#Tools by plan

Quant & Community supports multiple seats, with one API key per seat. Enterprise includes a dedicated MCP endpoint.

Your client only lists the tools your plan includes. If an assistant calls a tool outside your plan, the call returns an error result instead of data, for example: Tool "analyze_ticker" is not included in the hobbyist plan; upgrade your plan to use it. Tools available on this plan: get_quote.

#Tool reference

Symbols use standard notation (AAPL, BRK-B, ^GSPC, EURUSD=X, BTC-USD) and are upper-cased and validated before any data is fetched. Output is deliberately compact: rounded numbers, abbreviated volumes such as 52.3M, and one text block per call.

#get_quote

A fast consolidated quote.

{ "symbol": "AAPL" }

Returns symbol, as_of, price, change, change_pct and volume.

#analyze_ticker

The session and valuation of one instrument, in a single call.

{ "symbol": "AAPL" }

Returns:

• Session: price, change, OHLC, volume, gap_pct and range_position (0 at the day's low, 1 at its high).
• Stance: session_stance, one of strong_up, up, flat, down or strong_down.
• Valuation: market_cap, pe, pb, eps_ttm, roe and dividend_yield. Unreported values are omitted, and instruments without fundamentals, such as crypto, get a note instead of an error.

#explain_price_move

Structured context for the model to explain why a stock is moving.

{ "symbol": "NVDA" }

Returns:

• Move: direction, gap, range position and move_vs_atr (the move measured in ATRs).
• Technicals: RSI state, distance from SMA 20/50/200 in percent, moving-average trend, MACD, ATR and 30-day volatility.
• Earnings: the last reported quarter with its EPS surprise and days since the report, plus the next pending estimate.
• Signals: deterministic labels the model can reason over.

Missing technicals or earnings degrade to notes instead of failing the call.

#get_watchlist_brief

Summarizes up to 20 symbols in one Markdown table, made with a single batched quote request.

{ "symbols": ["AAPL", "MSFT", "NVDA", "BTC-USD"] }

**Watchlist brief** · 4 symbol(s) · as of 2026-10-16T14:30:05Z

| BTC-USD | 67412.50 | +812.40 | +1.22% | 66105.00–67980.00 | 28.4B |

Breadth: 3 up · 1 down · 0 flat · Best: NVDA +4.12% · Worst: MSFT -0.51%

Duplicate symbols are removed in input order, and symbols that can't be found are listed on a Not found: line.

#screen_market

Screens market movers and options activity. All fields are optional:

{ "asset_class": "eq", "metric": "all", "limit": 5 }

all returns gainers, volume leaders and the highest implied-volatility names. The high-IV list comes from the options screener, keeping the highest-IV contract per underlying, and is skipped for fx. If one list is unavailable it becomes a note; the call fails only if every list fails.

#Errors

Invalid input and data errors come back as MCP tool errors (isError: true) with a readable message, for example quote for ZZZZ: Symbol not found (status 404). Authentication problems are HTTP errors on the endpoint itself: a missing or invalid key returns 401.

Requests to the MCP endpoint count towards your plan's daily quota and rate limit like any other API request. Tool data is cached for a short time, so repeated questions from an assistant stay fast.
