kglite-c vs kglite-mcp-server vs kglite-bolt-server
Side-by-side comparison of Rust crates
C ABI for kglite — stable extern "C" surface over the kglite engine so non-Rust bindings (Go via cgo, JavaScript via napi, JVM via JNI, .NET via P/Invoke, …) consume a single C header rather than re-implementing wrappers in their host language. The Rust types (DirGraph, Session, CypherResult, KgErrorCode) live in the sibling `kglite` crate; this crate is glue.
MCP server for kglite knowledge graphs — pure-Rust single-binary frontend for cypher_query / graph_overview / save_graph / read_code_source plus the generic source / GitHub surface from mcp-methods. No libpython link.
Bolt v5.x protocol server for kglite knowledge graphs — pure-Rust single-binary frontend speaking the Neo4j wire protocol so the Neo4j driver ecosystem (Python/JS/Java/Go/.NET drivers, Cypher Shell, Neo4j Browser, BloodHound, LangChain Neo4jGraph) plugs in unchanged.
