# Configuring the daemon

Change the port, the embedder model, or enable tracing.

Create `~/.config/bookmark-context/config.toml`. Everything is optional; see the
[Configuration reference](/docs/reference/configuration/) for the full table.

## Change the port

```toml
[daemon]
port = 8080
```

Also update the extension's host permission and the URL it calls, and any MCP
client config that assumed 7331.

## Change the embedder model

```toml
[embedder]
model = "BAAI/bge-base-en-v1.5"
```

A larger model improves retrieval at the cost of index time and disk. **You must
re-index every bookmark after changing this** — existing vectors came from the
old model and can't be compared against new query embeddings.

Any model [fastembed](https://github.com/qdrant/fastembed) supports works. If a
policy in your organization bars Chinese-origin or US-Entity-List models (BAAI
was listed in March 2025), use a non-BAAI option such as
`sentence-transformers/all-MiniLM-L6-v2` or `intfloat/e5-small-v2`. See the
[Configuration reference](/docs/reference/configuration/#choosing-an-embedder) for the
full list and the licensing context.

## Enable tracing

```toml
[trace]
processes = true
mcp_tools = true
```

Or per-run with `BOOKMARK_CONTEXT_TRACE=1`. See
[Tracing & debugging](/docs/guides/tracing/).
