• body

  New navigation property

• download-bytes

  Download binary content from Microsoft Graph and return it as base64. Single tool for any binary read: drive file content, mail attachment, profile photo, Teams hosted content, meeting recording. Returns { contentType, encoding: "base64", contentLength, contentBytes }. For large drive/SharePoint file content, prefer get-download-url, which returns a pre-authenticated URL to stream bytes out-of-band instead of base64 through the agent context. With the server's blob output on, the bytes come back as a file resource instead (capped by the server's download limit); pass fileName to name it.

• download-bytes-to-file

  Write authenticated Microsoft Graph byte content to a local file on the server, returning { path, contentType, bytesWritten } instead of base64. The only out-of-band way to save mail attachments and meeting recordings, whose bytes are exposed solely through authenticated endpoints. Also handles profile photos and Teams hosted content. Writes to an absolute outputPath and never overwrites an existing file. stdio mode, or HTTP with --http-local-file-tools. For OneDrive or SharePoint file content, get-download-url is preferred — it returns a pre-authenticated URL for fully out-of-band download wi…

• execute-toolcan change or delete data

  Execute a Microsoft Graph API tool by name. Workflow: search-tools → get-tool-schema → execute-tool. Call get-tool-schema first for any tool you have not seen before — passing the wrong shape to parameters will fail validation or return a Graph 400. For list endpoints, prefer modest $top plus $select.

• get-download-url

  Resolve a short-lived, pre-authenticated download URL for Microsoft Graph binary content that exposes one (drive/SharePoint file content). The returned URL streams the bytes with NO Authorization header, so the client can fetch it straight to disk (e.g. curl) without round-tripping base64 through the agent context. Prefer this over download-bytes for any file above a few KB or any bulk download. Returns { downloadUrl, name?, size?, contentType? }. Mail file attachments (/messages/{id}/attachments/{id}/$value), meeting recordings and other $value byte endpoints have no pre-authenticated URL fro…

• get-tool-schemaread-only

  Returns the full parameter schema (name, placement, required, JSON Schema) for a tool discovered via search-tools. Call this before execute-tool so you know what parameters to pass and what enum values are valid.

• get-upload-url

  Mint a short-lived, single-use URL that this server serves for uploading a file as an attachment to a draft message or an event, so the bytes go straight from the caller to Microsoft Graph instead of passing as base64 through the agent context. target is the attachments collection of the item: /me/messages/{message-id}/attachments (a draft; create it first) or /me/events/{event-id}/attachments. PUT the raw file bytes to the returned uploadUrl with a Content-Length (e.g. curl -T file "<uploadUrl>"); the response confirms the attachment. Files under 3 MB are attached directly, larger ones (up to…

• list-accountsread-only

  List all Microsoft accounts configured in this server. Use this to discover available account emails before making tool calls. Reflects accounts added mid-session via --login.

• login

  Authenticate with Microsoft account

• logout

  Log out from Microsoft account

• parse-teams-url

  Converts any Teams meeting URL format (short /meet/, full /meetup-join/, or recap ?threadId=) into a standard joinWebUrl. Use this before list-online-meetings when the user provides a recap or short URL.

• read-mail-text

  Triage view of up to 20 mail messages at once, as text with the bulk junk removed: invisible padding, image placeholders and quoted reply history (forwards keep theirs). Links are kept: Safe Links, Proofpoint and Google redirects are unwrapped to the real address and tracking parameters (utm_* and similar) dropped; only an address still over 300 characters (a tracking redirect) is shortened to ⟦link: domain⟧. Everything else (signatures, footers, whitespace) is left as the message has it; line endings become \n and ⟦ ⟧ in the body itself appear as [ ]. Use get-mail-message for the raw body or …

• remove-account

  Remove a Microsoft account from the cache. Accepts email address (e.g. user@outlook.com) or account ID. Use list-accounts to discover available accounts.

• search-toolsread-only

  Description is built at runtime.

• select-account

  Select a Microsoft account as the default. Accepts email address (e.g. user@outlook.com) or account ID. Use list-accounts to discover available accounts.
