langflow-kb
Server Configuration
Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|
| OPENAI_API_KEY | No | OpenAI API key, required only if you want to use the `langflow_kb_search_docs` semantic search tool. The four catalog tools work without it, and the search tool tells you what is missing instead of failing silently. |
Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| langflow_kb_describe_componentA | Devuelve todos los campos de un componente de Langflow: tipo, opciones, valor por defecto y cuales estan ocultos tras el modo avanzado. Busqueda por nombre exacto sobre la instancia indexada. |
| langflow_kb_search_fieldsA | Busca en todo el catalogo que componentes declaran un campo con cierto nombre, o que campos existen de cierto tipo. Coincidencia exacta: buscar 'ocr' no encuentra 'ocr_engine'. Pasa nombre o tipo, no ambos. |
| langflow_kb_list_componentsB | Lista los componentes disponibles en la instancia indexada, con su categoria. Acepta filtro por categoria. |
| langflow_kb_search_docsA | Busca por significado en la documentacion de Langflow y devuelve los pasajes mas cercanos, cada uno con la URL que abre su seccion exacta. Para preguntas conceptuales. La documentacion esta en ingles. Cada resultado trae su cercania: valores bajos significan que no hay nada realmente parecido en el corpus. |
| langflow_kb_statusA | Informa que artefactos de la knowledge base estan construidos, de que version provienen y cuando se generaron. El servidor es de solo lectura: no reconstruye nada, solo avisa si hace falta. |

Scored across 5 tools
Each tool targets a distinct operation: listing components by category, semantic doc search, exact component description, exact field-catalog search, and KB status. search_docs (meaning-based, docs) vs search_fields (exact match, catalog) are clearly differentiated by description, and list_components vs describe_component differ by scope.
All tools share the langflow_kb_ prefix and mostly follow snake_case verb_noun (list_components, search_docs, describe_component, search_fields). The lone noun-only 'status' is a minor deviation but still readable and predictable.
Five focused tools are well-scoped for a read-only knowledge-base server, each earning its place with no redundancy. This is squarely in the ideal 3-15 range.
The surface covers listing, semantic doc search, exact component/field lookup, and artifact status, providing coherent lifecycle coverage for a read-only KB. Minor gap: no direct tool to fetch a complete doc page beyond ranked passages, but URLs are returned to work around it.
