OUR ASSESSMENT

Strengths
  • 8,241 GitHub stars.
  • 100 commits on main in the last 30 days. Top cadence in the directory.
  • Rust core with multi-language bindings.
  • 97+ document formats supported.
  • CLI, REST API, and MCP server in one project.
Weaknesses
  • Elastic License 2.0 restricts hosting kreuzberg as a managed service for third parties.
  • Score docked from 4.7 to 4.5 for the SaaS-restriction clause.
  • Rust toolchain required for source builds; pre-built binaries via release artefacts.
Security Notes

Elastic License 2.0 forbids running kreuzberg as a managed service for third parties; direct internal use is fine. Document extraction may pull PII from uploaded files; treat the agent flow as having access to potentially sensitive content. Operator scopes filesystem access via the path argument.

Best For

Agent flows that ingest user-uploaded documents; document intelligence pipelines that need PDF/Office/image extraction inside agents; multi-language teams who want one extraction toolchain across Rust, Python, Ruby, Java, Go, and TypeScript.

SOURCES & VERIFICATION

We don't take any single directory's word for it. Before scoring, we cross-reference 4 public MCP sources, install the server ourselves against the clients we cover, and record when we last re-verified.

// How other directories see it

The same server, 4 different lenses. We reconcile these signals into our editorial score, which is why our number sometimes diverges from a directory-aggregate star count.
