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, Cypher, Gremlin, GraphQL, and GraphDB/RDF4J-compatible access 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]].
