# Create proof (`proofable_verify`)

> Create a saved proof from a signed-in MCP session and finish supported ownership checks without leaving the chat.

Use **[`proofable_verify_or_guide`](./verify-or-guide)** as the normal trust path. It reuses a qualifying proof when one exists or returns the one next step needed to finish verification.

Use **`proofable_verify`** when the signed-in account can complete a known check in-session and a new proof is actually needed. Ownership checks finish here. Share a hosted link only when this tool returns one.

Use **`proofable_proofs_check`** only when the user explicitly needs a yes/no eligibility, gate, or access answer.

When signed in, **omit `walletAddress`**. The tool uses your profile account from `proofable_context`. For `ownership-basic`, omit `owner`. The signed-in account is filled in.

## Input

| Field | Required | Notes |
| - | - | - |
| `verifierIds` | Yes | One or more check IDs |
| `walletAddress` | No | Omit when signed in; required only when acting for another account |
| `data` | No | Check inputs (see each [check](../verification/verifiers)) |
| `chain` | No | CAIP-2 chain when needed |
| `signature` | No | Provided in the finalize step |
| `signedTimestamp` | No | Provided in the finalize step |
| `options.returnUrl` | No | Where to send the user if a hosted step is needed |
| `options.publishToHub` | No | Record the proof on the hub chain. Offchain by default. Does not change who can see the proof. |

```json theme={"system"}
{ "verifierIds": ["ownership-basic"], "data": { "content": "Hello Proofable" } }
```

Signed-in sessions do not send `signature` or `signedTimestamp`. Those fields exist only when the session cannot authorize the account.

## Output

A plain-language **Passed**, **Action needed**, or **Blocked** result. On success, the tool also returns the proof ID in `qHash` for your server. A hosted link appears only when the check needs an outside step.
