Diagnose why a Bifrost gateway, memory injection, or skill discovery isn't working in Claude Code or Claude Desktop. Triggers on 'bifrost not working', 'mcp not connecting', 'memory not injecting', 'skill_search failing', '401/403 from bifrost', 'bifrost debug', 'gateway unreachable', 'mcp_registration_failed', 'desktop connector failing', 'oauth error', 'incompatible auth server', 'dynamic client registration', 'trusted hosts'.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Bifrost Diagnostics
Work through this decision tree to isolate and fix the problem.
## 1. Check credentials are set (shell env, or plugin config)
On the CLI:
```bash
echo "URL set: ${BIFROST_URL:+yes}${BIFROST_URL:-NO — missing}"
echo "VK set: ${BIFROST_VK:+yes}${BIFROST_VK:-NO — missing}"
```
If missing: `export BIFROST_URL=https://<your-gateway-host>/mcp` and
`export BIFROST_VK=vk_<your-key>` (add both to `~/.zshrc` or `~/.bashrc`).
On Desktop and claude.ai there is no shell, so this check does not apply.
Credentials come from the plugin's install-time config values
(`gateway_url`, `virtual_key`, and the opt-in `auto_login`). Run `/plugin configure` to
view or change them.
Symptom if the key is wrong/missing: 401 or 403 from every bifrost tool call.
## 2. Check the bifrost MCP server is registered
```bash
claude mcp get bifrost 2>/dev/null || echo 'bifrost: MISSING at user scope'
```
The server can come from either the plugin's shipped `.mcp.json` (plugin
installed + enabled → shows up in `/mcp`) or a user-scope registration.
If neither: run `/bifrost-mcp-setup` for manual wiring instructions.
Then restart Claude Code for CC to pick up the change.

How to install
mdr add nexenio/bifrost-plugin/bifrost-debug@sha256:9c3e5c06ca6d6aa0The line at the top of this page pins the label git:20261009.f9cad52, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
