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

1. 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).
2. 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).

Pricing on this page is indicative — see eodhd.com/pricing for current rates.

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.

Skills

Core Skill: eodhd-api

Full access to all 72 EODHD endpoints via Python client and curl. Handles any financial data request.

Workflow Skills

Agent

Financial Analyst

The agents/financial-analyst.md agent autonomously:

• Selects appropriate skills based on the query
• Combines multiple data sources for comprehensive analysis
• Leads with conclusions, then supporting data
• Includes disclaimers and data freshness notes

Slash Commands

Plugin commands are namespaced under eodhd-api:.

MCP Server

The EODHD MCP Server v2 provides:

• 72 tools across 15 categories (prices, fundamentals, options, technicals, news, sentiment, macro, etc.)
• OAuth 2.0 authentication
• 100+ embedded docs as MCP resources
• 3 prompt templates for common workflows
• Smart ticker resolution — handles ambiguous symbols
• Rate limiting & retry — built-in resilience

Connection via .mcp.json:

{
  "eodhd": {
    "type": "http",
    "url": "https://mcp.eodhd.com/v2/mcp"
  }
}

Usage Tips

Claude Code treats installed skills as optional context. To ensure the skill activates:

1. Mention it explicitly: Use the eodhd-api plugin. ...
2. Add to CLAUDE.md: Always use available skills for financial data requests.
3. 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
