Install
From source
git clone https://github.com/arnd/openarchiver-mcpThis server has no ConduID identity, so agent calls to it are not receipted. Pin the version you install and review the source before granting it credentials.
Tools (4)
check_integrityRe-compute the SHA-256 hashes of an archived email and its attachments and compare them against the hashes stored at archival time — proof that a message has not been altered or corrupted in storage.
Parameters not published.
get_attachmentDownload an attachment by its `storagePath`. Default returns it inline (text → text, images → image content, other binaries → base64). With `mode: "file"` it saves the bytes to a server-managed temp file and returns only the path — handy for large binaries to keep base64 out of the context (path only usable when the server runs locally; the server picks the path, callers can't).
Parameters not published.
get_emailFetch one email by id: metadata, full body, and an attachment list (each with a `storagePath`).
Parameters not published.
search_archiveFull-text search across archived emails (subject, body, **and extracted attachment text**). Returns compact hits, each with an `id`.
Parameters not published.
