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.

157 tools. 11 resources. 10 prompts. Structured output on every tool. Zero boilerplate.

Install

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

The JSON config is identical for all tools. Only the file path changes.

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.

Invoicing

"Show me all unpaid invoices"
"Create an invoice for Acme SL with 10h of consulting at 95/hour"
"Mark invoice abc123 as paid"
"How much has ClientName been invoiced this year?"

Expenses

"Log a 59.99 EUR expense for Adobe Creative Cloud, category: software, tax-deductible"
"List all expenses from January"
"What did I spend on travel last quarter?"

Clients

"Add a new client: TechStart SL, NIF B12345678, email [email protected]"
"Show me all my clients"
"Update ClientName's address to Calle Mayor 1, Madrid 28001"

CRM

"Add a contact to Acme SL: Ana Garcia, CTO, [email protected]"
"Log a call with TechStart: discussed Q2 proposal, they're interested in upgrade"
"Add a note to ClientName: prefers invoices in English, payment NET 30"
"Show me all activities for Acme SL"

Quotes

"Create a quote for Design Studio: logo design (2000 EUR) + brand guidelines (3500 EUR)"
"Show me all pending quotes"

Webhooks

"Set up a webhook to notify https://my-app.com/hook when invoices are paid"
"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. All 157 tools are CRUD operations over the REST API.

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 [email protected]"                     --> 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]"

The server translates tool calls into REST API requests. It handles authentication, rate limiting (automatic retry with backoff on 429), pagination, and error mapping.

Two transports:

• stdio (local) -- npx @frihet/mcp-server with FRIHET_API_KEY
• Streamable HTTP (remote) -- https://mcp.frihet.io/mcp with Bearer token or OAuth 2.0+PKCE

Environment variables

| Variable | Required | Default | |----------|----------|---------| | FRIHET_API_KEY | Yes (stdio) | -- | | FRIHET_API_URL | No | https://api.frihet.io/v1 | | FRIHET_TOOL_MODE | No | full |

Tool exposure: depth served on demand

Frihet's differentiator is depth — full ES/EU fiscal coverage plus native compliance (VeriFactu, TicketBAI, Facturae/FACe/KSeF), banking, CRM, HR/payroll, stay/PMS and POS. But a flat list of every tool, loaded into an agent's context up front, is the 2026 context-rot problem: it crowds out the task and degrades tool selection before any work begins.

FRIHET_TOOL_MODE lets you choose how that depth is exposed.

| Mode | Behavior | |------|----------| | full (default) | All tools are exposed with their full descriptions and schemas. Unchanged from previous releases — existing setups are unaffected. | | grouped | Progressive disclosure. Each tool's description collapses to a one-line [group] summary — full schema via describe_tool('name'), and three lightweight discovery tools are added. The agent loads depth only for the tools it actually needs. |

In grouped mode the tools are unchanged — same names, same input schemas, same behavior. Only the up-front context cost changes. Discovery flows through three meta-tools:

• list_tool_groups() — the domain map (invoicing, expenses, fiscal/compliance, banking, CRM, HR/payroll, stay/PMS, POS, intelligence, products, platform) with a one-line blurb and tool count for each.
• search_tools(query) — free-text search across tool name, title, summary and group; returns matching tools with their group, summary, read-only flag and input fields. Optional group filter and limit.
• describe_tool(name) — the full original description and input fields for one tool, on demand, before you call it.

// claude_desktop_config.json — opt in to grouped mode
{
  "mcpServers": {
    "frihet": {
      "command": "npx",
      "args": ["@frihet/mcp-server"],
      "env": {
        "FRIHET_API_KEY": "fri_...",
        "FRIHET_TOOL_MODE": "grouped"
      }
    }
  }
}

This is an opt-in exposure layer only — it never changes a tool's logic, name or behavior, and full mode is byte-identical to before. The same interceptor pattern powers the OpenAI-safe profile (FRIHET_OPENAI_MODE).

API limits

| Limit | Value | |-------|-------| | Requests per minute | 100 per API key | | Results per page | 100 max (50 default) | | Request body | 1 MB max | | Webhook payload | 100 KB max | | Webhooks per account | 20 max |

Rate limiting is handled automatically with exponential backoff.

Current limitations

• No OCR or file upload -- the MCP works with structured data, not images or PDFs. Planned for a future release.
• Single company -- one API key maps to one Frihet workspace. Multi-company support is not yet available.
• Frihet account required -- you need an active account at app.frihet.io and an API key (starts with fri_).
