The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
convert_drawing_pdf Convert a drawing PDF between metric and imperial ~339
Produce a converted copy of a technical-drawing PDF with every recognised value stamped in place (white cover over the original callout, converted text in matching size/rotation) — dimensions, ± tolerances, fit classes, Ø/R callouts, threads. The input file is never modified. Without `classifications`, a heuristic converts unambiguous callouts plus (by default) bare numbers as lengths; for full control call extract_drawing_text first and pass per-token classifications. Requires a PDF with a text layer — scanned drawings need the web app (https://metric-to-imperial-converter.imnoo.com). Converted values are stamped over the original callouts. Verify safety-critical dimensions before manufacturing use.
| Name | Type | Req | Description |
|---|---|---|---|
| bare_numbers | string | – | heuristic mode only — 'convert' (default) treats bare numbers as lengths (year-like and id-like integers excluded); 'skip' converts only unambiguous callouts |
| classifications | array | – | authoritative per-token classification: when provided, ONLY listed tokens (minus skips) are converted |
| input_path | string | yes | path to the source drawing PDF (read-only) |
| output_path | string | – | where to write the converted PDF (default: next to the input as <name>.<target>.pdf) |
| overwrite | boolean | – | allow replacing an existing output file |
| page | integer | – | 1-based page to convert (default 1); other pages pass through unchanged |
| source_system | string | – | unit system of the source drawing (default auto-detect from its text) |
| target_system | string | – | default: the opposite of the source system |

convert_text Convert an engineering callout string ~215
Convert a printed drawing callout (or short text with several callouts) between metric and imperial, preserving notation: "Ø30 H7" → "Ø1.1811 H7", "84±0.1" → "3.3071±0.0039", "R13" → "R0.5118", "M8" → "5/16-18 UNC", "1/4-20 UNC" → "M6". Angles (°) are left unchanged. Set category=surface to read bare numbers as Ra roughness instead of lengths. assume_lengths=true additionally converts every remaining number as a length (for tolerance-table rows like "bis 30").
| Name | Type | Req | Description |
|---|---|---|---|
| assume_lengths | boolean | – | fallback: convert every number as a length when nothing else matched |
| category | string | – | how to read bare numbers (default dimension = length; surface = Ra roughness) |
| from | string | yes | unit system the text is currently in |
| text | string | yes | – |
No output schema declared.
No examples provided.
convert_value Convert a single engineering value ~200
Convert one engineering value between metric and imperial with shop-floor precision rules. Kinds: length (mm⇄in), tolerance_deviation (a ± deviation, keeps an extra significant digit), geometric_tolerance (GD&T value), surface_roughness (Ra µm⇄µin), weight (kg⇄lb), thread (designation lookup, e.g. "M8" ⇄ "5/16-18 UNC"). Returns the exact value, the display-rounded value, and how it was derived (exact/rounded/table/nearest) with a confidence score.
| Name | Type | Req | Description |
|---|---|---|---|
| designation | string | – | thread designation, e.g. "M8", "M8x1.25", "1/4-20 UNC" — required for kind=thread |
| from | string | yes | unit system the value is currently in |
| kind | string | yes | – |
| value | number | – | numeric value — required for every kind except thread |
No output schema declared.
No examples provided.
extract_drawing_text Extract a drawing PDF’s text layer ~144
Read the printed text tokens of one page of a technical-drawing PDF: each token with its index, text and position (page points, top-left origin, rotation in degrees), plus page geometry and a heuristic guess of the drawing’s unit system. Use the token indices to build `classifications` for convert_drawing_pdf when you want to decide yourself which tokens are convertible values (e.g. mark a bare "3.2" next to a surface symbol as category=surface, or a title-block number as skip).
| Name | Type | Req | Description |
|---|---|---|---|
| page | integer | – | 1-based page number (default 1) |
| path | string | yes | path to the drawing PDF |
No output schema declared.
No examples provided.
lookup_thread Cross-reference metric ⇄ inch threads ~103
Look up the closest standard counterpart of a thread designation (ISO metric coarse ⇄ Unified UNC), with major diameters, pitch/TPI and how close the match is. Omit `designation` to get the whole cross-reference chart (M2–M30).
| Name | Type | Req | Description |
|---|---|---|---|
| designation | string | – | e.g. "M8", "M12x1.75", "5/16-18 UNC", "#8-32 UNC" — omit for the full chart |

Is the com.imnoo/drawing-converter MCP server safe to use?
com.imnoo/drawing-converter scores 84 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 21 September 2026. It declares no install or post-install scripts. 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 com.imnoo/drawing-converter MCP server expose?
com.imnoo/drawing-converter exposes 5 tools: convert_value, convert_text, lookup_thread, extract_drawing_text, convert_drawing_pdf. Their descriptions and schemas cost roughly 1,001 tokens of context every time the server is loaded.
Is the com.imnoo/drawing-converter MCP server still maintained?
com.imnoo/drawing-converter is still listed as active in the MCP registry. We last reached this channel on 21 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 com.imnoo/drawing-converter MCP server under?
com.imnoo/drawing-converter declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
