signalscope-api

signalscope-api is a cursor rule for coding agents from signalscope/cursor-plugin. It costs 15 tokens per session (1,006 once invoked), scanned A, original, MIT.

Working rules for using the SignalScope API through MCP tools, including authentication methods, ticker formatting, signal meanings, and tool access limits.

In plain words
What is it for?
Use them when searching tickers, reading market signals, checking signal stages, retrieving prices or history, and preparing SignalScope-based analysis.
Why use it?
They help an assistant send valid requests and interpret signals consistently, while avoiding unavailable or incorrectly authenticated operations.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

signalscope-api scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SignalScope API Conventions

Authentication

Two methods — the MCP server uses whichever is configured:

  • SIGNALSCOPE_API_KEY — subscription-based. Flat rate, full access, daily quota. Generate at signalscopes.com/profile.
  • SIGNALSCOPE_WALLET_PRIVATE_KEY — x402 pay-per-call in USDC on Base. No account needed. Costs: trending/network $0.01, ticker/history/performance/related $0.005, AI report $0.05.

Free (no auth): search_tickers, get_methodology. API key only (not x402): list_scans, get_scan, get_signals, portfolio, watchlist, prices, stats.

Symbol format

Always pass ticker symbols in UPPERCASE. The MCP tools normalise automatically, but be consistent in output and reasoning (AAPL, not aapl or Aapl).

Signal stages

Stage Meaning Sources
Emerging Low-conviction — only 1 source detected this ticker 1
Building Building conviction — 2 sources 2
Consensus High-conviction breakout signal 3+
Filtered Pump-and-dump flagged — excluded from default results

Prefer Consensus for trade recommendations. Building is valid for watchlist adds. Emerging warrants further research before acting.

AI score vs Opportunity score

  • AI score (0–100): Evidence strength — how strongly the underlying signals support a breakout thesis
  • Opportunity score: Early-mover rank within the scan — how early this ticker was detected relative to others

Both are available in get_trending sortBy options (aiScore, opportunityScore).

AI score interpretation

Score Signal strength
70–100 Strong — high confidence breakout candidate
50–69 Moderate — worth monitoring
0–49 Weak — low conviction, caution advised

P&D flags

If pndFlagged: true, the ticker triggered 3+ of SignalScope's 11 pump-and-dump detection rules. Treat these with significant caution. The pndFlags array lists which specific flags triggered.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

signalscope-api is a cursor rule published in the GitHub repository signalscope/cursor-plugin (0 stars, last pushed 5mo ago), licensed MIT. It adds 15 tokens to every session and 1,006 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
