## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, 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)

  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (50% of tools); any adoption earns full credit.
- **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 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (4)

### `probe` (~416 tokens)

Probe a document

Read facts about one local PDF, Microsoft Office, or Apple iWork document without opening or rendering it: page, slide, and sheet counts; title, author, and dates; encryption, macro, signature, and active-content signals; structure; embedded assets; and integrity. Handles .pdf, .docx/.xlsx/.pptx, legacy .doc/.xls/.ppt, and modern .key/.numbers/.pages.

Start with targets ["@summary"], or ["@security"] to triage an untrusted file. Prefer this over unzipping the document or parsing its bytes by hand.

Reports facts ABOUT the document, never its text: it does not extract, render, run macros, follow external references, or open a network connection.

Input parameters:

- `budget` (object): Override the level's resource limits. Raise after a BUDGET_EXCEEDED error.
- `level` (string): Probe budget and eligible paths. header: identity only. metadata (default). deep: higher-cost paths, needed only when a target's min_level says so.
- `min_confidence` (string): Weakest evidence a path may offer. Default high; lower it to accept an approximation.
- `path` (string, required): Path to the document. The filename extension selects the format driver, and the container is then verified against it.
- `target_confidence` (object): Per-target override, e.g. {"slide_count": "exact"} to force the authoritative path.
- `targets` (array): Short names (slide_count), canonical names (powerpoint.slide_count), or presets: @header, @summary, @security, @structure, @assets, @quality, @format, @all. Defaults to the driver's own set. Call lis…
- `view` (string): report: full evidence — value, confidence, path, and cost per target. values: a compact target-to-value map.

Output parameters:

- `schema_version` (number)
- `status` (string)

### `probe_batch` (~347 tokens)

Probe several documents

Probe many local documents in one call — inventory a folder, triage a batch of uploads, or compare a set of files. One engine process handles the whole batch, so this is much cheaper than calling probe once per file.

Takes literal paths; expand any glob yourself first. Returns one entry per path, in the order given, each carrying that file's report or its own error envelope. A file that fails does not affect the others.

Defaults to the compact "values" view because inventory rarely needs per-target evidence; pass view: "report" when it does.

Input parameters:

- `budget` (object): Override the level's resource limits. Raise after a BUDGET_EXCEEDED error.
- `level` (string): Probe budget and eligible paths. header: identity only. metadata (default). deep: higher-cost paths, needed only when a target's min_level says so.
- `min_confidence` (string): Weakest evidence a path may offer. Default high; lower it to accept an approximation.
- `paths` (array, required): Document paths, at most 64 per call. Literal paths only.
- `targets` (array): Short names (slide_count), canonical names (powerpoint.slide_count), or presets: @header, @summary, @security, @structure, @assets, @quality, @format, @all. Defaults to the driver's own set. Call lis…
- `view` (string): report: full evidence — value, confidence, path, and cost per target. values: a compact target-to-value map.

Output parameters:

- `reports` (array): One entry per requested path, in order. A per-file failure is confined to it.

### `list_formats` (~45 tokens)

List supported formats

List the document formats DeckProbe can inspect: drivers, the extensions each one handles, and where support stops. Call this when you are unsure whether a file type is supported at all.

### `list_targets` (~149 tokens)

List targets for a format

List every target a format supports, with its aliases, value type, minimum probe level, cost class, and which @selectors include it. Call this before naming a target you have not already seen — probe rejects an unknown one rather than guessing.

Input parameters:

- `detail` (string): compact (default): target names, aliases, descriptions, levels, and selector membership. full: the complete report, including each target's JSON Schema fragment and every selector's expanded member l…
- `format` (string, required): A format profile from list_formats, such as "pdf", "docx", "xlsx", "pptx", "doc", "xls", "ppt", "key", "numbers", or "pages".

## Common questions

### What is the io.github.deckflow/deckprobe MCP server?

io.github.deckflow/deckprobe is an MCP server listed in the public MCP registry as io.github.deckflow/deckprobe. Inspect PDF, Office, and iWork documents without rendering: counts, metadata, security signals. This page covers its npm package (@deckflow/deckprobe-mcp).

### Is the io.github.deckflow/deckprobe MCP server safe to use?

io.github.deckflow/deckprobe scores 95 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 20 September 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. 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 io.github.deckflow/deckprobe MCP server expose?

io.github.deckflow/deckprobe exposes 4 tools: probe, probe_batch, list_formats, list_targets. Their descriptions and schemas cost roughly 957 tokens of context every time the server is loaded.

### Is the io.github.deckflow/deckprobe MCP server still maintained?

io.github.deckflow/deckprobe is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the io.github.deckflow/deckprobe MCP server under?

io.github.deckflow/deckprobe declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
