Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"onedrive-blade-mcp","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.

# onedrive-blade-mcp A token-efficient [MCP](https://modelcontextprotocol.io) server for OneDrive and SharePoint file operations via Microsoft Graph API. 18 tools covering browse, read, search, upload, share, versioning, delta sync, and SharePoint — with pipe-delimited output, write-gating, and dual auth. ## Why this over generic file MCPs? | | **onedrive-blade-mcp** | Generic file / Graph MCPs | |---|---|---| | **Output** | Pipe-delimited, null omission | Raw JSON blobs (10-50x more tokens) | | **Delta sync** | `drive_delta` tracks file changes incrementally | Full re-listing every time | | **SharePoint** | Browse sites, libraries, and files natively | OneDrive-only or not supported | | **Safety** | Write-gated by default, delete requires `confirm=true` | Varies | | **Auth** | Dual: device code (interactive) + client credentials (headless/CI) | Single flow | | **Versioning** | `drive_versions` for full file history | Not exposed | | **Thumbnails** | `drive_thumbnail` for image previews | Not available | Delta sync is the killer feature for AI workflows — track what changed in a folder without re-listing thousands of files. ## Features - **18 tools** — browse, read, search, upload, share, version history, delta sync, SharePoint - **Token-efficient output** — pipe-delimited, field-selected, null fields omitted - **Write-gated by default** — reads are free, writes require `ONEDRIVE_WRITE_ENABLED=true` - **Delta sync** — incremental file change tracking with delta tokens - **SharePoint integration** — sites, document libraries, and files - **Dual authentication** — device code for interactive, client credentials for headless - **Sharing management** — create links, check permissions, control scope - **FastMCP 2.0** — stdio and HTTP transports ## Quick Start ```bash # Install git clone https://github.com/groupthink-dev/onedrive-blade-mcp.git cd onedrive-blade-mcp uv sync # Configure export ONEDRIVE_TENANT_ID="your-tenant-id" export ONEDRIVE_CLIENT_ID="your-cl…
