Description
Official Twelve Data integration for OpenClaw and ClawHub. Provides real-time and historical financial market data for stocks, forex, crypto, ETFs, indices,...
Usage Guidance
This appears to be the official Twelve Data integration and is internally consistent. Before installing: (1) verify the publisher/repository (SKILL.md points to twelvedata.com and GitHub links) to ensure you trust the source; (2) be prepared to provide a Twelve Data API key only if you do not run the MCP server locally — do not paste your API key into chat prompts or public code; (3) if you run the MCP server, inspect its repository and configuration (network exposure, auth storage) before running it on a public host; (4) confirm the registry metadata (homepage/env declarations) with the publisher if you want exact provenance. Otherwise the skill’s behavior is proportional to its stated purpose.
Capability Analysis
Type: OpenClaw Skill
Name: twelvedata
Version: 1.0.0
The 'twelvedata' skill bundle is a legitimate integration for the Twelve Data financial market data API. It provides comprehensive documentation and instructions for an AI agent to access stocks, forex, and crypto data via an MCP server or Python SDK. The instructions in SKILL.md are focused on functional best practices (e.g., symbol validation, batching) and security (protecting API keys), with no evidence of malicious intent, data exfiltration, or harmful prompt injection.
Capability Assessment
Purpose & Capability
Name/description (Twelve Data market data) match the runtime instructions and reference docs. The skill reasonably prefers an MCP server and offers a fallback to the official SDK/REST/WebSocket APIs — those are appropriate for this purpose. Note: registry metadata lists no homepage/credentials, but SKILL.md references twelvedata.com and an optional TWELVE_DATA_API_KEY for direct API access (see environment_proportionality).
Instruction Scope
SKILL.md contains clear, scoped instructions for using an MCP server, the official Python SDK, or direct REST/WebSocket calls. It advises validating symbols, respecting rate limits, not hardcoding API keys, and reading local reference files before calling endpoints. There are no instructions to read unrelated files or exfiltrate data.
Install Mechanism
This is an instruction-only skill with no install spec or bundled code. Commands shown (pip install mcp-server-twelve-data) are normal for installing a connector; nothing is downloaded from obscure URLs or written by the skill itself.
Credentials
The skill sensibly uses a Twelve Data API key when the MCP server is not available. The registry metadata reported 'no required env vars', but SKILL.md documents an optional TWELVE_DATA_API_KEY (only for fallback). This optional credential is proportional to the stated functionality; confirm the registry listing and whether the platform will prompt for the key only when needed.
Persistence & Privilege
The skill does not request always:true and does not declare any system-wide persistence. Autonomous invocation is allowed (platform default) which is appropriate for an on-demand data connector.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install twelvedata - After installation, invoke the skill by name or use
/twelvedata - Provide required inputs per the skill's parameter spec and get structured output
