Tools
This server runs locally, so its tools are listed by your MCP client once it starts.
Environment variables
| Name | Description |
|---|---|
BNF_USER_AGENTOptional | Identify your own client. The project's own identifier is appended, so the BnF can always reach a person. |
BNF_MIN_INTERVAL_MSOptional | Minimum milliseconds between requests. Default 3000, which is also the floor. |
BNF_TIMEOUT_MSOptional | Deadline for one SPARQL query, in milliseconds. Default 60000. |
BNF_MAX_RETRIESOptional | Attempts after a busy answer. Default 3. |
BNF_CACHE_TTL_MSOptional | How long an answer is kept in memory, in milliseconds. Default 900000. Zero turns the cache off. |
BNF_LOG_LEVELOptional | silent, error, info or debug. Default error. Logs go to stderr. |
