01 / What your agents can do

Build agents that answer like analysts.

Built for agents, token efficient by default. Computed metrics and market context arrive in compact responses, ready for reasoning instead of parsing.

Built for the context window

Your agent gets the analyst layer first, not a pile of raw feeds it has to clean, join, and recalculate.

Computed context

Valuation percentiles, trend state, drawdowns, and relative strength arrive precomputed.

Primary-source depth

Earnings, SEC filings, filing sections, and Form 4 insider activity are one call away.

Small by default

Curated responses keep context lean, with up to 30 years of daily price history when asked.

Fundamentals & valuation

Price, profile, valuation, statements, and payouts in the shape agents need.

snapshotprofilevaluationfundamentalsdividends

Technicals & price action

Technicals, price action, relative strength, drawdowns, history, and comparisons.

technicalsprice actionhistorycompare

Earnings, filings & insiders

Earnings setup, upcoming events, SEC filings, filing sections, and insider activity.

earningscalendarfilingsinsider

Search & coverage

Search the supported universe and route the agent to the tools that fit.

Every number traces to a primary source — market data and company filings.

03 / Context benchmark

Spend tokens on reasoning, not parsing raw feeds.

Same workflow. Noxstock returns actionable insights your agent can reason with; traditional APIs can fill the model’s context window in a couple of tool calls.

04 / Easy setup

Paste the prompt. Your agent handles setup.

Copy this prompt into Claude Code, Codex, or Cursor and get Noxstock running in minutes.

Integrate Noxstock into this project so you can pull decision-ready US stock and ETF context.

Step 1: Read the integration guide
Read https://noxstock.com/SKILL.md and follow it. If you cannot access it,
continue with the instructions below.

Step 2: Understand the project
If this is an existing codebase, inspect the language, framework, package
manager, environment-variable conventions, existing MCP/agent config, plus
current market-data or finance code. Ask what stock-market workflow Noxstock
should support unless I only asked you to connect MCP.

Step 3: Add the hosted MCP server
Use endpoint: https://api.noxstock.com/mcp
Use header:   X-API-Key: $NOXSTOCK_API_KEY
Store the key in the project's normal secret/env system. Do not commit it.

For Claude Code, use:
claude mcp add --transport http noxstock https://api.noxstock.com/mcp \
  --header "X-API-Key: $NOXSTOCK_API_KEY"

For JSON MCP config, use:
{
  "mcpServers": {
    "noxstock": {
      "url": "https://api.noxstock.com/mcp",
      "headers": { "X-API-Key": "$NOXSTOCK_API_KEY" }
    }
  }
}

Step 4: Verify
Confirm the noxstock_* tools loaded — snapshot, valuation, fundamentals,
earnings, dividends, technicals, price_action, history, compare, filings,
insider, calendar, search, and coverage.

Run noxstock_snapshot for AAPL and show me a one-line read that includes
freshness and as_of. If it fails, diagnose and fix the env/config issue.

Step 5: Usage rules
For stock questions, use the Noxstock tools first. Pass through freshness,
as_of, unsupported reasons, and unavailable/null explanations. Never invent a
number; if a field is missing or unsupported, say so.
