Is this an official FreeAgent MCP server?

No. It is Memtro's MCP server with Memtro's FreeAgent connector behind it: the connector reads FreeAgent through its API with the credentials you connect on Dashboard → Connections, and FreeAgent publishes nothing here. The same endpoint carries every other system you connect and Memtro's memory tools.

Nothing on top of Memtro. One price per organisation by its number of users, from $50 a month for up to 10 users after a 7-day free trial, with every connector, the MCP server, jobs and memory included. You bring your own model keys.

Can it change anything in FreeAgent?

Not yet. Today every FreeAgent tool reads, searches or lists; when it gains actions, each is marked, granted by name and used only when you ask, so nothing is created, sent, updated or deleted until you say so.

Any MCP client that speaks Streamable HTTP: Claude Code, Cursor, Claude Desktop, OpenCode, Codex, Zed, Windsurf, Cline and the Anthropic and OpenAI SDKs. There is no local process to run; the server is remote and authenticated with your key.

FreeAgent MCP server

FreeAgent in any MCP client, through Memtro: FreeAgent does not publish this server. Memtro's FreeAgent connector reads FreeAgent through its API with the credentials you connect, and one endpoint hands those tools, every other system you connect and Memtro's memory tools to Claude Code, Cursor, Claude Desktop or anything else that speaks Streamable HTTP, as you.

What the model can do

Small-business accounting: contacts with balances, sales invoices, supplier bills, bank accounts and transactions, projects and timeslips, plus profit and loss, trial balance, balance sheet and tax deadlines. Read-only.

Reads

freeagent_contactsFind FreeAgent contacts (clients and suppliers) by name, organisation or email, with outstanding balance and status.
freeagent_invoicesSales invoices: filter by view (open, overdue, paid, draft, recent_open_or_overdue, last_3_months), contact, invoice-date window or reference.
freeagent_billsSupplier bills (purchases to pay): view open, overdue, paid or recurring, by contact and bill-date window, with due dates, amounts and status.
freeagent_bankBank accounts with balances.
freeagent_reportsAccounting reports in the company currency: profit_and_loss (from_date/to_date or accounting_period such as 2025/26; default current year to date)…
freeagent_projectsProjects with budget, billing rate and status.

Connect it

First connect FreeAgent on Dashboard → Connections, then add Memtro to your client once. The FreeAgent tools appear alongside the tools of everything else you have connected; nothing is configured per connector.

Claude Code

One command registers the server; the tools are then available in every session.

claude mcp add --transport http memtro https://platform.memtro.com/api/mcp \
  --header "Authorization: Bearer sk-memtro-..."

Cursor

Add the server to .cursor/mcp.json in the project, or to the global file under ~/.cursor/.

{
  "mcpServers": {
    "memtro": {
      "url": "https://platform.memtro.com/api/mcp",
      "headers": {
        "Authorization": "Bearer sk-memtro-..."
      }
    }
  }
}

Claude Desktop

Create a personal API key on Dashboard → Profile → API keys. In Claude Desktop add an MCP server of type HTTP with URL https://platform.memtro.com/api/mcp and the header Authorization: Bearer sk-memtro-…

OpenCode

A remote server in opencode.json.

{
  "mcp": {
    "memtro": {
      "type": "remote",
      "url": "https://platform.memtro.com/api/mcp",
      "headers": {
        "Authorization": "Bearer sk-memtro-..."
      }
    }
  }
}

Any other client

Add an MCP server of type HTTP (Streamable HTTP, stateless) at https://platform.memtro.com/api/mcp with the header Authorization: Bearer sk-memtro-.... Codex, Zed, Windsurf, Cline and the SDKs all take a remote server this way.

Who may use it

The key identifies the person, and the server offers that person the tools they may use everywhere else in Memtro. A shared FreeAgent connection is used by the teams an administrator granted it to, tool by tool, on the Permissions page; a personal connection is used by its owner alone, and its tools that act stay off until the owner allows them. See Teams and permissions and Connectors.
