## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 64/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 515 tokens (~128/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 40/100
  - Stability observed for 12 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 92/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 75% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (4)

### `inspect_csv` (~89 tokens)

Inspect CSV

Return record, maximum column and cell counts with up to 20 preview records. Preserve ragged and empty records; never infer types or a delimiter.

### `sort_csv_rows` (~133 tokens)

Sort CSV rows

Stably sort data records by an explicit zero-based column using literal code-unit string order, asc or desc. Header defaults to preserved. No numeric, date or locale inference. Reject missing target columns.

Input parameters:

- `column` (integer, required): Zero-based column index. Every data record must contain this column.

### Is the CSV File Tools MCP server safe to use?

CSV File Tools scores 76 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the CSV File Tools MCP server expose?

CSV File Tools exposes 4 tools: inspect_csv, filter_csv_rows, sort_csv_rows, edit_csv_cells. Their descriptions and schemas cost roughly 446 tokens of context every time the server is loaded.

### Does the CSV File Tools MCP server require authentication?

No. We connected to CSV File Tools without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the CSV File Tools MCP server still maintained?

CSV File Tools is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
