Use Marxel in Claude

Bring a hiring brief and up to five CVs into a Claude conversation. Claude proposes job-related criteria from the brief and asks you to confirm up to eight of them. Must-have is used for explicit requirements, Responsibility for role duties and Nice-to-have for desirable experience.

Marxel then builds a review workspace. For each candidate and criterion it shows whether the CV evidences it, needs clarification or doesn't evidence it, with a cited quote from the CV and an interview question to verify it. Marxel's server rejects any quote that doesn't appear word for word in the CV text you supplied.

The connector doesn't rank candidates, sort them into Screening Buckets, make hiring decisions or contact anyone. Your team reads the evidence and decides what to do next. A quote check confirms the words appear in the supplied text; it doesn't confirm that the CV is genuine or that Claude's reading of it is right.

When you want to keep a review, you can save the selected candidates to your Marxel organisation. That creates a Screening Job with your confirmed criteria and starts Marxel screening.

Use either of these:

1. 1. Once Marxel is listed in Claude's connector directory, add it from there.
2. 2. In Claude, open Settings → Connectors, choose Add custom connector and enter https://mcp.marxel.co/mcp.

You don't need a Marxel account to compare CVs. Saving a review needs a Marxel account connected through OAuth sign-in.

The four review tools work without an account. The three save tools use OAuth, with Marxel as the authorisation server. To connect, you sign in to Marxel and approve the request on Marxel's consent page.

The connector requests two scopes:

• reviews:write lets it list your organisations and save confirmed reviews into an organisation you choose. It doesn't give access to your existing Screening Jobs or Candidates.
• offline_access keeps the connection working while you remain signed in to Marxel. Access tokens themselves expire after five minutes.

Marxel also has an optional read-only mode that would add a reviews:read scope for existing jobs and candidate evidence. It is turned off on the public connector.

Before anything is saved, Claude lists your organisations, you choose one, and you confirm the import. The save tool only accepts requests marked as confirmed, and Marxel checks that you are still a member of the chosen organisation.

On every request, Marxel verifies the token's signature, issuer, audience, scope and expiry. It also rechecks that your Marxel session is still active, your account isn't suspended, the OAuth client hasn't been disabled and your consent is still in place. A change to any of these takes effect on the next request.

When you review candidates

Claude sends the hiring brief, confirmed criteria, CV text and the quotes it extracted to Marxel's connector server. The server checks each quote against the supplied text and returns the workspace. It doesn't store this content, doesn't create or change any Marxel records and doesn't call an AI provider.

The connector server records operational usage for each tool call: the tool name, timing, whether it failed, the client name and version, the server version, the protocol version and an anonymous session ID. CV text, hiring briefs, tool arguments and results are excluded from these records.

When you save a review

Only the candidates you select are imported. Marxel keeps:

• The hiring brief, when supplied, and your confirmed criteria, on a new Screening Job.
• For each selected candidate: their name, current role and company, the CV text Claude supplied, and the source label of the CV.
• The evidence status, quote, source and interview question for each criterion, saved as a candidate note and kept separate from Marxel's own screening results.

Original uploaded files and the Claude conversation are not transferred. The temporary copy of the review used for the import is cleared once the import succeeds. Marxel then screens the imported candidates as it does any other Screening Job, using the AI providers listed on our subprocessors page.

Saved Screening Jobs and Candidates are ordinary Marxel records, handled like any other job in your organisation. For details, see our privacy policy, security overview and data processing agreement. Claude handles conversation data under Anthropic's own terms.

In Claude: remove or disconnect the Marxel connector in Settings → Connectors. Claude then stops calling Marxel's tools.

In Marxel: there's no settings page for revoking connected apps yet. Because every request is checked against the Marxel session you approved it with, signing out of Marxel in that browser stops further saves. Changing your password in Settings → Security also signs out your other sessions. To have the authorisation removed from your account, email support@marxel.co.

Disconnecting doesn't delete reviews you already saved. Delete those Screening Jobs in Marxel like any other job.
