Registry code: 31ab1b7c6a87b342
Turns messy tabular files into clean, typed, compressed Parquet, then lets you look inside without reading everything.
Typical flow: convert_to_parquet (returns an artifact_id and a schema report) -> inspect_parquet or preview_parquet to look -> query_parquet to answer questions with SQL. Pass the artifact_id between calls instead of re-sending the file.

- Is aimart-parquet live?
- Yes — it answered the hub's last check (checked 29m ago). It answered 100% of checks over the last 30 days.
- Is aimart-parquet free to use?
- No — it charges per call, from 0.002 0x036C…CF7e, quoted in its own 402 answers.
- What tools does aimart-parquet have?
- 6 tools: convert_to_parquet, inspect_parquet, preview_parquet, query_parquet, verify_provenance, request_capability.
- Is aimart-parquet safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
convert_to_parquet paid never probed
Convert a messy data file into clean, typed, zstd-compressed Parquet. Use this first for any CSV/TSV, JSON/NDJSON, Excel, SPSS, Stata or SAS file, or a digital PDF with tables. It detects the format, encoding and delimiter; skips title rows; repairs broken JSON; pulls tables out of PDFs (merging tables that continue across pages); infers int/float/bool/date/timestamp columns (including 1.234,56 and $1,234 formats) while keeping IDs with leading zeros as text; normalizes column names to snake_case; keeps SPSS/Stata/SAS variable and value labels; and can validate against an expected_schema. Returns an artifact_id (pass it to inspect_parquet / preview_parquet / query_parquet), a download link, and a per-column report: type, null count, values that did not fit the chosen type, and warnings. Price: $0.02 USDC per successful call, paid via x402.

Describe a Parquet file from its footer without reading rows: row count, columns, types, null counts, min/max per column, and SPSS/Stata/SAS labels.

Run one read-only DuckDB SELECT over a Parquet file, available as table `data`; join more files by passing `tables` ({name: artifact_id}, up to 7 besides data), e.g. a GL against a bank statement. Supports aggregates, window functions, CTEs, DESCRIBE data and SUMMARIZE data. Up to 1000 rows are returned; `truncated` says if more matched. Writes, file access and multiple statements are rejected. Example: SELECT region, sum(units) FROM data GROUP BY 1 ORDER BY 2 DESC. Price: $0.005 USDC per successful call, paid via x402.

Free. Check that a file this service produced is authentic and unaltered: verifies the post-quantum ML-DSA-65 (NIST FIPS 204) signature in an artifact's `provenance`, and with artifact_id also re-checks the stored file's hash and size against the signed manifest.

Free. If none of these tools does what you need — a file type we reject, an output we do not produce, a missing operation — describe the task, the formats involved, and the most you would pay per call. The operator reads these to decide what to build next. Do not include personal or confidential data.

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id31ab1b7c6a87b342.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/31ab1b7c6a87b342/claim.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
