freee_api_get error: company_id differs from the current company — use freee_set_current_company

The message pattern is "contains freee_set_current_company". freee-mcp (official), tool freee_api_get.

症状

• Passing a company_id that differs from the current company to freee_api_get is rejected with an error telling you to switch with freee_set_current_company.
• 現在の事業所と違う company_id を渡すと拒否され、freee_set_current_company で切り替えるよう返される。Observed 2026-09-24 through 2026-10-01, reproduced in daily observation.

該当条件

freee_api_get に、freee-mcp が保持する「現在の事業所」と違う company_id を渡したとき。

最初の確認

freee_list_companies で、使いたい事業所の API の id（8 digits）と現在の事業所を見比べる。The output is formatted text, not JSON; read the id out of the text.

解決手順

• Call freee_set_current_company first, using the API id (8 digits), not the 10-digit 事業所番号.
• Do the work with freee_api_get.
• Then switch back to the original company.
• 日本語: 先に freee_set_current_company で切り替え（API の id を使う）、終わったら元の事業所に戻す。

成功の確認

切り替え後の freee_api_get が目的の事業所のデータを返す。

• 確認日: 2026-10-01（最終観測）/ 2026-10-07（公開）
• 環境: Claude Code, transport stdio

解決しなかった場合

• 切り替えたのに 403 なら rest-403-forbiddenError-freee-invoices（アプリ権限）。
• id を 10 digits（事業所番号）で渡していないかを確認。
• human_step_required: no

調査の軌跡

• A6 T-02 (2026-10-20): one search with the tool name → freee-mcp README; solved the switch but not the switch-back.
• arm0-claude-run1-g1 / run2-g1 / run3-g1 (2026-10-20): README reached each time; the exact argument name of freee_set_current_company was not confirmed on any page; "switch back" was missing from all three answers; the 8/10-digit distinction appeared once, from prior knowledge.
• Dead ends seen: glama README mirror with no body, agentskills.so unreachable, directory pages that only re-post the README (one used an older tool name freee_set_company).
