What the freee connector does
The freee MCP server connects freee, Japan's cloud accounting suite, to Claude, ChatGPT and any MCP-compatible agent. Its 13 tools are not named accounting actions but generic HTTP verbs over freee's own API — four of them write. One connector therefore reaches accounting, payroll, invoicing and tax filing, and what a write touches depends on the path the agent picks.

Limits
- Beta, with no warranty. freee states the feature is provided as a beta version and disclaims any guarantee of completeness, accuracy, availability, usefulness, security or non-infringement of third-party rights, noting it may be updated at any time (freee, 2026).
- Outside freee's support service. freee states that external integrations using the MCP server fall outside the scope of its support, because they involve information and tools freee cannot handle. Bugs go to the repository's GitHub issues instead.
- The remote server does not cover freee Sign. freee's repository states Remote MCP support for its electronic-signature product is in preparation and only local operation is supported.
- Remote may lag the open-source version. freee aims for parity but states some operations may be unavailable remotely due to limits in the MCP specification.
- Some products need their own contract, client and permissions. freee's repository states that surveys, business registration, HR evaluation and tax filing each require the corresponding connection environment, OAuth client, contract plan and user permissions.
- No draft or confirmation stage is documented between an agent's decision to write and the request reaching freee.
- Responsibility for the AI tool is the customer's. freee states it is not involved in the selection, management or operation of the AI tool, and instructs customers to confirm that training opt-out is enabled in that tool.
- Documentation is Japanese only, which is a real barrier for an English-speaking finance team evaluating this connector.
- Rate limits are a known unknown. We observed
ratelimit-limit: 6000with a 60-second window on the MCP endpoint itself on 2026-09-09, but that governs our unauthenticated request. freee's public API documentation index does not state the limits that apply to authenticated freee API calls made through the connector, and we did not find them. - Tool safety is name-derived, not annotated. We hold no live safety annotations for any of the 13 tools.
Frequently asked questions
Does the freee MCP server post entries straight to the ledger?
It can. The freee connector exposes generic write verbs rather than named accounting actions, so whether a call drafts or commits depends entirely on which freee API path the agent chooses. freee's documentation describes creating invoices and registering data conversationally and documents no connector-level draft stage, preview or confirmation prompt. Treat any write instruction as immediate (freee, 2026).
What permissions does an AI agent get through the freee connector?
Exactly the permissions of the freee user who signed in, and no more. freee's help centre states that operations are possible only within the same scope as the logged-in user's permissions, and that actions beyond those permissions, such as retrieving data the user cannot view, will not occur. freee describes this as the same security standard as existing Public API applications (2026).
Do I have to install the freee Agent Skills as well as the connector?
Yes. freee's help centre states the Agent Skills package must be installed so the AI uses freee correctly, and warns that without it correctly configured the connector may consume a large number of tokens. freee-mcp offers many operations, and the skill injects the API reference the agent needs rather than loading everything (freee, 2026).
Is the freee MCP server a finished product or a beta?
freee publishes it as a beta. Its disclaimer states the feature is provided as a beta version with no warranty as to completeness, accuracy, availability, usefulness, security or non-infringement, and that it may be updated at any time. freee also places MCP-based external integrations outside the scope of its support service (2026).
What is the difference between the remote freee MCP server and the open-source version?
Hosting. freee states the open-source version requires you to build a development environment on your own computer and complete several configuration steps, while the remote version is hosted by freee so you only add a URL. freee aims for functional parity but notes some operations may be unavailable remotely due to MCP specification limits (2026).
Is the freee connector documentation available in English?
No. freee publishes its connector setup guide, FAQ and disclaimer in Japanese only, at support.freee.co.jp, and the open-source repository README is also Japanese. The Anthropic directory listing carries an English description, but every vendor-authored detail on this page was read from Japanese sources and translated (checked 2026-09-09).
Can freee's electronic signature product be used through the remote connector?
Not yet. freee's repository states that Remote MCP support for freee Sign is in preparation and that only running the MCP server locally is supported, through a separate freee-sign-mcp command with its own tools. The remote endpoint documented on this page therefore does not cover contract signing (freee, 2026).
Why does a freee API call fail with a company mismatch error?
The request carried a company_id that is not the currently selected business. freee's repository states that when a request includes company_id in a parameter or body it must match the current business, and a mismatch returns an error. Check the current business with freee_get_current_company and change it with freee_set_current_company (2026).
