lfx-exa
Exa web-search and contents tools as a standalone Langflow Extension Bundle.
What it ships
One component, registered under the exa bundle group:
- Exa Search (
ExaSearchToolkit, canonical IDext:exa:ExaSearchToolkit@official) — a toolkit exposing two tools for a Langflow Agent component or MCP client:search— search the web with Exa (auto/fast/instant/deepsearch types, category, domain allow/deny lists, published-date range), returning token-efficient highlights by default.get_contents— fetch highlights and/or full text for result IDs returned bysearch.
The component is built on the exa-py
SDK. It previously shipped inside the manifest-less lfx-bundles
metapackage on the deprecated metaphor-python client; the bundle name and
class name are unchanged, so saved flows load without migration changes.
The legacy metaphor_api_key field is still honored (hidden) — new flows
should use exa_api_key.
Install
pip install lfx-exa
pip install langflow already includes it.
Develop
The bundle is a uv workspace member of the Langflow monorepo:
uv sync
uv run pytest src/bundles/exa/tests -q
uv run lfx extension validate src/bundles/exa/src/lfx_exa
To iterate on the component with a live palette:
uv run lfx extension dev src/bundles/exa
