claude-vllm read `~/.config/opencode/opencode.jsonc` directly. Same shape is
useful; sharing the actual file is not — a credential rotation in opencode would
silently change what Claude Code authenticates with, and it couples two tools'
configs for no reason.
It now has its own `$XDG_CONFIG_HOME/mcpctl/claude-vllm.jsonc`, shaped like
opencode's (`provider.<name>.options.{baseURL,apiKey}` plus a `models` map), and
takes priority. The pi and prime-agent homes stay as a fallback so the command
works before any config exists; reading opencode's file is dropped.
No key is stored in the tool. `apiKey` may be a literal in the 0600 file,
`${ENV_VAR}`, or a bare env var NAME (the form pi's models.json already uses),
so the secret can live in the environment instead of on disk. `--init` reads it
from stdin when `--api-key` is omitted — keeping it out of shell history and out
of the process table, where an argument is visible to every user via `ps`.
`--list` prints at most a 10-character prefix.
`--init` records the context window for every model it can see, not just the
active one: recording only the default meant `--model something-else` silently
fell back to Claude Code's assumed 200k on a 393k model.

The gateway at llm.ad.itaz.eu is LiteLLM in front of vLLM, and LiteLLM already
serves the Anthropic Messages API on /v1/messages — verified with a real
completion. So Claude Code needs no bridge: pointing ANTHROPIC_BASE_URL at it is
the whole integration.
`claude-vllm` exists only to stop you pasting four exports each time. It reuses
what another agent is already configured with — ~/.pi/agent, ~/.prime/agent, then
opencode's config, first hit wins — taking the base URL and the credential from
the same source so one gateway's URL is never paired with another's key.
Beyond the obvious ANTHROPIC_* vars it sets two that are easy to miss:
- ANTHROPIC_SMALL_FAST_MODEL / ANTHROPIC_DEFAULT_HAIKU_MODEL, or the
background and summarisation calls ask the gateway for a real Haiku it does
not serve and every one 404s;
- CLAUDE_CODE_MAX_CONTEXT_TOKENS from the provider's declared contextWindow,
because Claude Code assumes 200k for models it has no table for — and
deepseek-v4-* is 393k, so it would auto-compact at half capacity.
On `claude-mcpctl`: mcpctl's LLM layer is a client, not a server. mcpd serves
/api/v1/llms (management) and its adapters call out to providers for gating,
prompt selection and agent chat; nothing serves /v1/messages. Routing Claude
through mcpctl would mean adding an Anthropic-shaped passthrough that re-wraps
LiteLLM — worth doing only if mcpctl in the LLM path buys something of its own
(per-project gating of model calls, prompt audit, budgets), which is a mcpd
endpoint rather than a wrapper script.
Verified: `claude-vllm --model deepseek-v4-fast -- -p "..."` completes against
deepseek on the homelab, with the unknown-model context warning gone.
