Bifrost for DeepSeek Harness

@brokkai/dsh-plugin-bifrost is a DeepSeek Harness bundle that gives dsh sessions Bifrost code intelligence over MCP. It ships the shared Bifrost launcher, which downloads and checksum-verifies the pinned native bifrost binary on first use; no manual binary installation is needed.

Bifrost tools appear to the model as mcp__bifrost__<tool> (for example

mcp__bifrost__search_symbols), serving the symbol|extended toolsets by

default.

Install

dsh plugin --profile <name> add @brokkai/dsh-plugin-bifrost

Verify the bundle joined the profile:

dsh --profile <name> --dump-config | grep -A2 dsh-plugin-bifrost

Then start dsh from your project directory:

cd /path/to/your/project
dsh --profile <name>

Workspace root

The analyzer binds to a project root chosen in this order:

1. The root config value on the plugin row. 2. The BIFROST_WORKSPACE_ROOT environment variable. 3. The working directory dsh was started from.

Start dsh from the project you want analyzed, or pin root explicitly.

Configuration

Override defaults by giving the plugin row a config block in your profile's cordis.patch.yml (later layers win per row, and a patch replaces the row's entire config value):

- id: bifrost
  name: '@brokkai/dsh-plugin-bifrost'
  config:
    root: /absolute/path/to/project
    toolsets: symbol|extended
    toolCallTimeoutMs: 240000
    env:
      BIFROST_BINARY_PATH: /usr/local/bin/bifrost

Recognized keys: root, toolsets (a Bifrost toolset expression such as

symbol|extended or core|nlp), serverName (default bifrost; changes the

mcp__<serverName>__ tool prefix), toolCallTimeoutMs (default 240000, sized for first-call binary download and analyzer warm-up), env (extra environment variables for the server subprocess), and failOnStartupError.

Note: dsh scrubs secrets-like variables (*KEY*, *PASSWORD*, *SECRET*, *TOKEN*) and all DSH_* variables from server subprocess environments. Any such variable Bifrost needs must be set explicitly under env.

Uninstall

dsh plugin --profile <name> remove @brokkai/dsh-plugin-bifrost

Development

The launcher (bin/bifrost-launcher.mjs) and release manifest (bifrost-release.json) are vendored copies of the canonical files in plugins/bifrost-agent; run npm run sync-launcher after changing the originals. npm test runs the offline test suite, including a byte-identity check of the vendored copies.
