## Tools

15 declared. Statically extracted from the shipped source — a floor on the surface, not a census.
- `search_data`
- `get_listing` — Get full details of one listing: complete description, price in DTM, and the file manifest (filenames, sizes, sha256 hashes). Use before deciding to buy.
- `preview_sample` — DISABLED pending a redesign — the old absolute cap returned whole small listings. Returns 403; use get_listing for the file manifest (names, sizes, sha256) inst
- `get_quote` — Get the exact on-chain purchase recipe for a listing: chain, marketplace and token addresses, amount in base units, and the approve + purchase calls. Use when y
- `purchase_data` — Buy a dataset in ONE call: checks the quote, approves the token spend if needed, pays on-chain in DTM, verifies the purchase with the marketplace, and returns a
- `my_purchases` — List everything this wallet has bought, with fresh download URLs (they expire 60 minutes after issue). Use to re-download past purchases.
- `my_listings` — List the listings this wallet created, newest first. The mirror of my_purchases — use it to find work you published and get it back. Requires DATUM_SIGNER_KEY.
- `download_data` — Download a listing as a zip bundle to the local filesystem. Works for a listing you bought, or one you created. Use after purchase_data, or any time you need a 
- `publish_listing`
- `update_listing` — Update a listing title/description you own. Price is immutable in v1 — delist and relist to change it.
- `delist_listing` — Remove your listing from search results. Past buyers keep download access. Requires DATUM_SIGNER_KEY.
- `post_request` — REQUEST data you need but cannot find: post an "in search of" notice that seller agents discover and fulfil. Write the description as the data you want, in what

## Install

**Verdict: install** — No blocking findings and no open coverage gaps — safe to install as configured.
**Config** (claude-code):
```json
"{\n  \"mcpServers\": {\n    \"datum-mcp-server\": {\n      \"command\": \"npx\",\n      \"args\": [\n        \"-y\",\n        \"datum-mcp-server\"\n      ],\n      \"env\": {\n        \"DATUM_SIGNER_KEY\": \"<YOUR_DATUM_SIGNER_KEY>\"\n      }\n    }\n  }\n}"
```
**Credentials it will ask for** (names only — Forge never holds a value):
- `DATUM_SIGNER_KEY` — Datum Signer Key (optional)
Placeholders only. Forge never holds, brokers, or transmits a credential value — replace each <YOUR_NAME> in your own config file. Do not send a value back to Forge; no Forge endpoint accepts one.
- This entry needs 1 credential (0 required). The generated config carries placeholders, so it will fail in the editor rather than at runtime if they are left unset.

## Blast radius

Moderate blast radius — holds an api key; runs on your machine.
- Floor 23, ceiling 23 (tier: moderate)
- This is impact, not likelihood. A high radius is not a defect: a filesystem server is supposed to write files. It is never part of the trust score.
