Complete plugin versus direct MCP

The release-ready plugin bundles these tools with the local evidence, confirmation and account-state skill. Until its verified marketplace listing is published, direct MCP remains the available tools-only fallback.

Choose permanent or temporary access

OAuth offers Sign in to Khimba for a permanent account with stable reconnect, or Continue as guest for temporary, unclaimed access. Ask Codex to call account_status for login or balance questions. A claim link starts interactive sign-in for an existing guest; verify account_status afterwards before treating the account as claimed.

Try a focused request

“What does DeepSeek think of my implementation plan?” or “Ask GLM to review my uncommitted changes for correctness, concurrency risks and missing tests.” With the complete plugin, Codex prepares relevant local evidence using the bundled skill. With direct tools only, inspect the declared context particularly carefully.

Approve before anything leaves

The preparation shows the exact model, question, paths, file count, token estimate and maximum dollar charge. Nothing is uploaded and no credit is reserved before explicit confirmation. If the requested model is unavailable, Khimba reports that rather than substituting another.

What returns

The completed opinion contains findings, assumptions, recommendations, token usage and final measured charge. Treat it as another reviewer’s input, not proof. Reproduce important claims with tests and source evidence.

Temporary guests can use up to USD 0.10 in promotional credit, limited to three successful calls and 24 hours after guest creation. The promotion ends when any one limit is reached. Pricing is measured official-provider cost plus a 30% platform markup.
