GAB dataset documentation

The GAB dataset is a release: a dated folder of open files that any client reads with a plain GET request. A small read-only interface lists the files and an MCP server gives the manifest, the file addresses and a citation text. No key, no sign-in and no rate plan is needed.

Entry points

• Manifest: GET https://gabrielosint.org/release/manifest.json lists every file with its size and its SHA-256 checksum, the version (2026-10-28) and the contacts.
• Linked data: GET https://gabrielosint.org/release/dataset.jsonld is a schema.org Dataset record.
• OpenAPI description: GET https://gabrielosint.org/openapi.json describes these requests for tools.
• Versioned list: GET https://gabrielosint.org/api/v1/files?limit=5 lists the files by page. Pass next as cursor for the next page.
• MCP server (read only, no sign-in): POST https://gabrielosint.org/mcp with JSON-RPC. Its card is at https://gabrielosint.org/.well-known/mcp/server-card.json. Tools: get_release_manifest, list_release_files, get_file_url, cite.
