Developers

Start with the language and graph protocol your application already uses.

Build paths

Command line

Install the CLI in one command:

curl -fsSL https://kotobase.net/install.sh | sh

It needs babashka and writes only to your own ~/.local.

SDKs

TypeScript, Python, and PHP clients share one transport and authentication contract.

Query protocols

Datomic Client API, SPARQL (including RDF4J HTTP path compatibility), Cypher, Gremlin, and GraphQL are tracked through explicit capability discovery and conformance tests.

AI and agents

Use the MCP endpoint at

https://kotobase.net/mcp

against the same tenant graph, or run

kotobase mcp

to emit the client configuration.

Local-first knowledge

Import or bidirectionally sync an Obsidian vault while preserving Markdown, frontmatter, and [[wikilinks]].
