Surface truth: the catalogue contains 158 canonical operations. The local full profile serves 163 tool names, 11 resources, and 10 prompts (158 canonical operations plus 5 fiscal aliases). The hosted grouped profile serves 166 tool names, 7 resources, and 10 prompts (the same names plus 3 discovery tools, with API-backed resources kept local-only). The separately reviewed OpenAI profile serves 33 tool names, 0 resources, and 0 prompts. Catalogue membership is not a promise that a backing API is enabled for every workspace.

What is this

An MCP server that connects your AI assistant to Frihet. Create invoices by talking. Query expenses in natural language. Manage your entire business from your IDE.

You:     "Create an invoice for TechStart SL, 40 hours of consulting at 75 EUR/hour, due March 1st"
Claude:  Done. Invoice INV-2026-089 created. Total: 3,000.00 EUR + 21% IVA = 3,630.00 EUR.

158 canonical operations. Five fiscal aliases. Ten prompts. The local package serves 11 resources; the hosted Worker deliberately serves the 7 static resources, while API-backed workspace resources remain local-profile only.

Try it instantly (no signup)

Kick the tires with zero setup — no account, no API key:

FRIHET_DEMO=1 npx -y @frihet/mcp-server

In demo mode the server answers from realistic example fixtures (Spanish invoices with IVA/IGIC, expenses, clients, products, a bank account, and more) — every record uses demo_-prefixed IDs and the server prints a DEMO MODE banner on startup. Nothing is persisted and no network call is ever made. Writes are simulated and fiscal actions (e-invoice, VeriFactu, TicketBAI, FACe, payroll) return a clearly-labeled simulation — never a real submission to any tax authority.

When you're ready for your real data, drop the flag and add your key (app.frihet.io → Settings → API keys). See Install below.

For AI agents

If you are an agent reading this repository rather than a person reading a page, everything you need is machine-readable and generated from the running server — you do not have to parse this README.

What	Where
Onboarding contract: quickstart per client, auth, safe workflow, human-authority tool lists, error recovery	docs/agent-onboarding.json — also shipped inside the npm package
Per-tool capability truth: callability, writesFrihet, externalInteraction, externalSideEffects	_meta["io.frihet/capability"] on every entry of tools/list
How to behave once connected	the instructions string returned by initialize — your client hands it to you automatically

Three rules the contract encodes, in short:

1. Orient before acting. get_business_context and the frihet://tax/rates resource decide the correct fiscal treatment. Do not recall a Spanish tax rate from memory.
2. Draft, show, stop. create_invoice, create_quote and create_credit_note all default to status=draft — no fiscal number, no hash, nothing sent to a tax authority. Present the draft and hand back.
3. Human authority is not yours to assume. Any tool with a non-empty externalSideEffects reaches a client's inbox, a webhook, money, or AEAT / VeriFactu / TicketBAI / FACe. Several also take confirm=true; that flag records a human decision — never set it to satisfy your own plan.

docs/agent-onboarding.json is regenerated from the live surface by npm run generate:agent-onboarding and gated in CI by npm run gate:agent-onboarding, so its tool lists and counts cannot drift from the server.

Install

One-line (Claude Code, Cursor, Copilot, Codex, Windsurf, Gemini CLI, and more)

npx skills add Frihet-io/frihet-mcp

Claude Code plugin (skill + MCP server in one install)

This repository is also a Claude Code plugin (frihet-erp): installing it wires up both the business-management skill and the MCP server.

# Try it locally
claude --plugin-dir /path/to/frihet-mcp

Marketplace availability is pending. Use the local plugin command above or the Claude Code MCP command below to connect today.

Skill invocation: /frihet-erp:frihet-mcp. The bundled .mcp.json launches @frihet/mcp-server via npx — set FRIHET_API_KEY in your environment (get one at app.frihet.io → Settings → API keys).

Claude Code — one command

claude mcp add frihet -s user -e FRIHET_API_KEY=fri_your_key_here -- npx -y @frihet/mcp-server
claude mcp list          # verify: frihet ✓ Connected

The CLI owns the config file, so there is nothing to hand-edit and no path to get wrong. (User scope writes ~/.claude.json, not ~/.claude/mcp.json.)

Codex CLI — one command

codex mcp add frihet --env FRIHET_API_KEY=fri_your_key_here -- npx -y @frihet/mcp-server
codex mcp list           # verify

Codex config is TOML, not JSON. codex mcp add writes:

[mcp_servers.frihet]
command = "npx"
args = ["-y", "@frihet/mcp-server"]

[mcp_servers.frihet.env]
FRIHET_API_KEY = "fri_your_key_here"

Pasting a JSON mcpServers block into ~/.codex/config.toml is a TOML parse error that takes down your whole Codex config, not just this server. Use the command above.

Claude Desktop, Cursor, Windsurf, Cline — JSON config

{
  "mcpServers": {
    "frihet": {
      "command": "npx",
      "args": ["-y", "@frihet/mcp-server"],
      "env": {
        "FRIHET_API_KEY": "fri_your_key_here"
      }
    }
  }
}

Tool	Config file
Claude Desktop	~/Library/Application Support/Claude/claude_desktop_config.json
Cursor	.cursor/mcp.json or ~/.cursor/mcp.json
Windsurf	~/.windsurf/mcp.json
Cline	VS Code settings or .cline/mcp.json

The JSON above is identical for these four clients; only the file path changes. Claude Code and Codex are not in this table — they manage their own config through the CLI commands shown above.

Remote (no install)

Use the hosted endpoint at mcp.frihet.io -- zero local dependencies, runs on Cloudflare Workers.

With API key:

{
  "mcpServers": {
    "frihet": {
      "type": "streamable-http",
      "url": "https://mcp.frihet.io/mcp",
      "headers": {
        "Authorization": "Bearer fri_your_key_here"
      }
    }
  }
}

With OAuth 2.0 + PKCE (browser-based login, no API key needed):

Clients that support OAuth (Claude Desktop, Smithery, etc.) can connect directly to https://mcp.frihet.io/mcp and authenticate via browser. The server implements the full OAuth 2.1 authorization code flow with PKCE.

Get your API key

1. Log into app.frihet.io
2. Go to Settings > API
3. Click Create API key
4. Copy the key (starts with fri_) -- it's only shown once

What you can do

Talk to your ERP. These are real prompts, not marketing copy.

"Show me all unpaid invoices"
"Create an invoice for Acme SL with 10h of consulting at 95/hour"

"List all expenses from January"
"What did I spend on travel last quarter?"

Clients

"List all my active webhooks"

What to expect

This MCP is a structured data interface -- you describe what you want in natural language, and the AI creates, queries, or modifies business records in Frihet. Most of the 158 canonical operations are CRUD operations over the REST API; the rest are read-only summaries and fiscal/e-invoice actions. Alias and discovery names are counted separately.

Works great:

"Create an invoice for TechStart SL, 40h consulting at 75 EUR/h"   --> creates the invoice
"Show unpaid invoices over 1,000 EUR"                               --> queries and filters
"Log a 120 EUR expense for the Madrid train, category: travel"      --> records the expense
"Update client Acme's email to billing@acme.es"                     --> modifies the record

Does not do:

• OCR or PDF scanning -- you cannot upload an invoice image and have it read
• File upload or attachment handling
• Image processing of any kind

If you need to digitize paper invoices or receipts, extract the data first (e.g., Claude Vision API, a dedicated OCR service, or manual entry), then use the MCP to create the record:

1. Scan/photograph the invoice
2. Use Claude Vision: "Read this invoice image and extract the vendor, items, amounts, and dates"
3. Then: "Create an expense in Frihet for [extracted data]"
