# Using Nisa with Merv

> Find the paper in Nisa, register it in Merv's project ledger by arXiv id — and what does not happen automatically.

Nisa and Merv share a RapidReview sign-in and a product switcher; they don't call each other. The bridge is an **arXiv id** your agent carries across. Concept: [How Merv and Nisa fit together](/docs/merv/concepts/merv-and-nisa).

<Steps>
  <Step title="Find the paper in Nisa">
    ```bash theme={"theme":{"light":"github-light","dark":"dark-plus"}}
    nisa search "direct preference optimization" --max-results 5
    nisa related 2305.18290 --n 10
    ```
  </Step>

  <Step title="Cite it in Merv">
    Your Merv-connected agent calls `litreview.cite` (an MCP tool call, not a shell command):

    ```json theme={"theme":{"light":"github-light","dark":"dark-plus"}}
    {
      "project_id": "proj_…",
      "arxiv_id": "2305.18290",
      "targets": [{ "type": "experiment", "id": "exp_…" }],
      "note": "baseline for the alignment comparison"
    }
    ```

    Exactly one of `url` / `doi` / `arxiv_id` (else `provide exactly one of url, doi, or arxiv_id`); up to 20 `targets` of type `litreview_section`, `experiment`, or `claim`; `note` ≤ 300, `title` ≤ 200 characters.
  </Step>

  <Step title="Keep the review current">
    A targeted `litreview.edit` afterwards. In plans, cite portably — `arXiv:2305.18290` — never Merv's internal `paper_…` id.
  </Step>
</Steps>

Merv deduplicates arXiv/DOI/URL forms of one paper and fetches metadata from `arxiv.org`, `ar5iv.org`, `openreview.net`, `semanticscholar.org`, `aclanthology.org`, `nature.com`, `paperswithcode.com`, `doi.org`, `dx.doi.org`; other hosts register with the `title` you pass.

Nothing flows automatically and nothing records that a citation came from Nisa. Your agent can run `nisa` itself if the Nisa skill is installed next to the Merv plugin — [Install → Give your coding agent the skill](/docs/nisa/start/install#give-your-coding-agent-the-skill).
