Stamp, upgrade, and verify Bitcoin timestamps via AI agents. No API keys required.
Stamp, upgrade, and verify Bitcoin timestamps via AI agents. No API keys required. That is what the otskit mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.
The server publishes 8 tools. What each one is for:
create_timestamp — Stamp a SHA-256 hash against 4 public OTS calendarsupgrade_timestamp — Check if a pending stamp has been confirmed in Bitcoinverify_timestamp — Verify a stamp - proves hash existed before a given Bitcoin blockinspect_timestamp — Inspect a stored proof file without network callslist_pending — List stamps with status, retry count, and filterswatch — Open a terminal window monitoring pending stamps and attempting due upgradeshash_file — Compute the SHA-256 of a local file and return it as a 64-char hex string (no network calls)stamp_file — Compute SHA-256 of a local file and stamp it on Bitcoin in one step@otskit/mcp on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.
This sits in the monitoring and observability group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Otskit's toolset — create_timestamp, upgrade_timestamp, verify_timestamp and 5 more — is a fair guide to whether it matches your workflow. It is maintained by AlexAlves87; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
| Tool | What it does |
|---|---|
| create_timestamp | Stamp a SHA-256 hash against 4 public OTS calendars |
| upgrade_timestamp | Check if a pending stamp has been confirmed in Bitcoin |
| verify_timestamp | Verify a stamp - proves hash existed before a given Bitcoin block |
| inspect_timestamp | Inspect a stored proof file without network calls |
| list_pending | List stamps with status, retry count, and filters |
| watch | Open a terminal window monitoring pending stamps and attempting due upgrades |
| hash_file | Compute the SHA-256 of a local file and return it as a 64-char hex string (no network calls) |
| stamp_file | Compute SHA-256 of a local file and stamp it on Bitcoin in one step |
