Installation
Claude Code (Plugin System)
# Register the marketplace
/plugin marketplace add EodHistoricalData/eodhd-claude-skills
# Install the plugin
/plugin install eodhd-api@eodhd-claude-skills
Plugin commands are namespaced. After install, invoke commands with the
eodhd-api: prefix — e.g. /eodhd-api:eodhd-analyze AAPL, not /eodhd-analyze.
Type / to see them listed under the eodhd-api: group.
Claude Code (Community Marketplace)
If you have the Anthropic community marketplace added:
/plugin marketplace add anthropics/claude-plugins-community
/plugin install eodhd-api@claude-community
MCP Server (Direct)
The plugin includes .mcp.json for automatic MCP Server connection:
{
"eodhd": {
"type": "http",
"url": "https://mcp.eodhd.com/v2/mcp"
}
}
Manual Setup
git clone https://github.com/EodHistoricalData/eodhd-claude-skills.git
export EODHD_API_TOKEN="your_token_here"
Prerequisites
- EODHD account + API token — sign up at eodhd.com. Free tier works for evaluation; production usage typically needs a paid plan (see Access Tiers below).
- Python 3.8+ for the helper client (stdlib-only, no
pip install needed)
Access Tiers
The plugin itself is MIT-licensed and free. Data access is gated by your EODHD subscription. The skills degrade gracefully — if an endpoint requires a tier you don't have, you'll get a clear 402 Payment Required (not a crash).

|---|
| Free (details) | $0/mo, 20 calls/day | US tickers, EOD prices (past year), 15-min delayed quotes, exchanges list, US Treasury rates. Good for testing the plugin. |

Quick Start
1. Set your API token
export EODHD_API_TOKEN="your_token_here"
2. Use slash commands
Plugin commands are namespaced under eodhd-api::
/eodhd-api:eodhd-analyze AAPL # Full company analysis
/eodhd-api:eodhd-compare AAPL MSFT # Side-by-side comparison
/eodhd-api:eodhd-market # Market overview
/eodhd-api:eodhd-screen high dividend large cap # Stock screening
/eodhd-api:eodhd-macro # Macro dashboard
3. Use the Python client directly
python skills/eodhd-api/scripts/eodhd_client.py --endpoint eod --symbol AAPL.US --from-date 2025-01-01 --to-date 2025-03-31
python skills/eodhd-api/scripts/eodhd_client.py --endpoint fundamentals --symbol MSFT.US
python skills/eodhd-api/scripts/eodhd_client.py --endpoint screener --limit 20
4. Use in prompts
Use the eodhd-api plugin. Pull daily prices for AAPL.US from 2025-01-01 to 2025-03-31
and give me a trend analysis with key support/resistance levels.

Usage Tips
Claude Code treats installed skills as optional context. To ensure the skill activates:
- Mention it explicitly:
Use the eodhd-api plugin. ...
- Add to CLAUDE.md:
Always use available skills for financial data requests.
- Use slash commands: They always activate the skill
Troubleshooting
SSL: CERTIFICATE_VERIFY_FAILED on macOS — Python installed from the official python.org installer
does not register the system CA certificates, so the client's HTTPS calls fail with:
Request failed: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed:
unable to get local issuer certificate
Fix it once by running the bundled certificate installer for your Python version:
# Adjust the version to match your install (3.11, 3.12, 3.13, ...)
open "/Applications/Python 3.13/Install Certificates.command"
(Homebrew/pyenv Python builds usually don't need this.)
MCP tools fail to authenticate / OAuth page shows an error — confirm the MCP server is reachable, then
fall back to the Python client by setting export EODHD_API_TOKEN="your_token", which bypasses OAuth.
Contributing
See CONTRIBUTING.md for guidelines. Priority areas:
- Expand Python client with additional endpoints
- Add example workflows
- Improve documentation with real-world examples
