fennoa-agentic

Fennoa Accounting API as agent tools — three ways to use Fennoa's accounting API from AI agents and CLI tools.

Approach	Best for
Plugin / Marketplace	Easiest install — one command in Claude Code
MCP Server	Claude Code, Claude Desktop, VS Code — structured tool calls
Bash wrapper	Terminal, scripts, CI/CD — no Node.js runtime needed
Claude Code Skill	Ad hoc queries from Claude Code — no config needed

Plugin / Marketplace install

The fastest way to get started from Claude Code:

/plugin marketplace add ljack/fennoa-agentic

Then install the plugin:

/plugin install fennoa

This gives you the /fennoa skill immediately — no manual file copying needed.

To install via CLI instead:

claude plugin install fennoa@ljack/fennoa-agentic

Prerequisites

• Fennoa account with API access
• API key and company code from Fennoa settings

A — MCP Server

A Node.js MCP server exposing all 12 Fennoa endpoints as typed tools.

Setup

npm install
npm run build

Configure Claude Code

Add to ~/.claude.json:

{
  "mcpServers": {
    "fennoa": {
      "command": "node",
      "args": ["/path/to/fennoa-agentic/dist/index.js"],
      "env": {
        "FENNOA_API_KEY": "your_api_key",
        "FENNOA_COMPANY_CODE": "your_company_code"
      }
    }
  }
}

Configure Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "fennoa": {
      "command": "node",
      "args": ["/path/to/fennoa-agentic/dist/index.js"],
      "env": {
        "FENNOA_API_KEY": "your_api_key",
        "FENNOA_COMPANY_CODE": "your_company_code"
      }
    }
  }
}

Development (no build step)

{
  "mcpServers": {
    "fennoa": {
      "command": "npx",
      "args": ["tsx", "/path/to/fennoa-agentic/src/index.ts"],
      "env": {
        "FENNOA_API_KEY": "your_api_key",
        "FENNOA_COMPANY_CODE": "your_company_code"
      }
    }
  }
}

B — Bash Wrapper

fennoa.sh wraps all endpoints with curl. No Node.js required.

Setup

cp .env.example .env   # add your API key and company code

Or export environment variables directly:

export FENNOA_API_KEY=your_api_key
export FENNOA_COMPANY_CODE=your_company_code

Usage

# Reference data
./fennoa.sh get_periods
./fennoa.sh get_accounts
./fennoa.sh get_vatcodes

# Ledger
./fennoa.sh get_ledger 2025-01-01 2025-12-31
./fennoa.sh get_ledger 2025-01-01 2025-12-31 --accounts 1900,1910 --limit 500
./fennoa.sh get_account_balance 1910 2025-12-31

# Create a journal entry (JSON from stdin)
echo '{
  "entry_date": "2025-03-17",
  "series_code": "GL",
  "description": "Office supplies",
  "rows": [
    { "account": 4400, "debit": 121.00, "vatcode_id": 1 },
    { "account": 1910, "credit": 121.00 }
  ]
}' | ./fennoa.sh add_statement

# Attach a receipt PDF
./fennoa.sh upload_attachment 1234 receipt.pdf

# Budgets
./fennoa.sh get_budgets
cat budget.json | ./fennoa.sh create_budget
cat budget.json | ./fennoa.sh update_budget 42

./fennoa.sh help   # full command reference

C — Claude Code Skill

Install once, use from any Claude Code session via /fennoa. No MCP config or running process needed.

Install

mkdir -p ~/.claude/skills/fennoa
cp skill/fennoa.md ~/.claude/skills/fennoa/SKILL.md

Usage

/fennoa show me all purchase invoices from Q1 2025
/fennoa what is the balance on account 1910?
/fennoa post a journal entry for a 100€ office supply purchase

Claude will use fennoa.sh if available, or fall back to direct curl calls.

---

Authentication

All approaches use the same credentials:

• FENNOA_API_KEY — API key from Fennoa settings
• FENNOA_COMPANY_CODE — your company's identifier
• FENNOA_BASE_URL — optional, defaults to https://app.fennoa.com

See SKILL.md for full API reference, key concepts, and workflow examples.
