Nanograph

Build Nanograph datasources from Markdown or PDF corpora and serve them through MCP or a small HTTP/JSON wrapper.

What v1 supports

• Ingest commands: nanograph-ingest seed --config ..., build, and smoke
• Server commands: nanograph-mcp --registry ... and nanograph-http --registry ...
• MCP tools: sources, source, documents, document, sections, search, passage
• HTTP routes: GET /healthz, GET /datasources, GET /datasources/{name}, GET /datasources/{name}/documents, GET /datasources/{name}/documents/{document_id}, GET /datasources/{name}/documents/{document_id}/sections, POST /search, POST /passage, and POST /mcp

Use /healthz for health checks. Other application responses use the same schema-versioned envelope.

Search modes:

• mode = "keyword" for all datasources
• mode = "search" only for datasources built with embeddings enabled

Quick start

nanograph-ingest smoke --config examples/corpus-markdown.toml
nanograph-http --registry examples/datasources-public.toml --host 127.0.0.1 --port 8765

The public registry example uses only home, exposure, and enabled for each datasource. Host-local path overrides such as database and config are outside the documented v1 contract.
