Available components
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. How we score → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability38
- 0% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Fail
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 2333 tokens (~259/item across 9 items; 8 tools + 1 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (63% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 8 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 10 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
- Supports UI / widget rendering.Pass
How do I install the Aspicio MCP server?
Aspicio is a hosted endpoint at https://aspicio-api.frontsail.app/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

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 →
describe_doc Describe a drawing of any supported format ~266
Return a structured JSON summary of a drawing in any supported format (DXF or PDF), detected from its bytes rather than its name. Use this when you do not know which format you have; the reply names the format that was read. Covers the whole drawing by default, including every page of a multi-page PDF; pass `space` (a name from the reply's `spaces`) to scope it to one page or sheet. When the user wants to see or explore the drawing themselves, prefer view_dxf (interactive viewer) — if your platform gates it behind user approval, offer it and ask rather than substituting a static render.
| Name | Type | Req | Description |
|---|---|---|---|

describe_dxf Describe a DXF drawing ~302
Return a structured JSON summary of a DXF drawing — units, bounding box, layers (with the color actually drawn), per-type entity counts, and any skipped/unsupported types. Use this to answer structural questions (what layers exist, how many parts, what size, is it to scale) without rendering an image. For a PDF use describe_pdf; if you do not know the format, use describe_doc. Covers the whole drawing by default, including every page of a multi-page PDF; pass `space` (a name from the reply's `spaces`) to scope it to one page or sheet. When the user wants to see or explore the drawing themselves, prefer view_dxf (interactive viewer) — if your platform gates it behind user approval, offer it and ask rather than substituting a static render.

describe_pdf Describe a PDF drawing ~293
Return a structured JSON summary of a PDF drawing — units (points), bounding box, layers, per-type entity counts, the text it contains, and what was skipped (images, shadings, transparency). Use this for structural questions about a PDF without rendering it. For a DXF use describe_dxf; if you do not know the format, use describe_doc. Covers the whole drawing by default, including every page of a multi-page PDF; pass `space` (a name from the reply's `spaces`) to scope it to one page or sheet. When the user wants to see or explore the drawing themselves, prefer view_dxf (interactive viewer) — if your platform gates it behind user approval, offer it and ask rather than substituting a static render.

load_dxf_for_viewer Load a DXF for the viewer widget ~84
Internal: returns DXF bytes (base64) for the in-chat viewer. Called by the widget, not the model.
| Name | Type | Req | Description |
|---|---|---|---|
| length | integer | – | Byte length of the requested range |
| offset | integer | – | Byte offset of the requested range |
| source | string | yes | http(s) URL of the drawing (same guards as the other tools) |
| Name | Type | Req | Description |
|---|---|---|---|
| byteLength | integer | yes | Total size of the whole file |
| bytesBase64 | string | yes | The requested bytes, base64 |
| offset | integer | yes | Byte offset this slice starts at |
No examples provided.
render_doc Render a drawing of any supported format ~312
Render a drawing in any supported format (DXF or PDF) to a PNG you can look at, detected from its bytes rather than its name. Use this when you do not know which format you have. Renders the first page/sheet by default; pass `space` (a name from a describe reply's `spaces`) to render another one. Some chat UIs do not display the returned image to the user: for URL sources the result also includes a direct image link — show it (e.g. as a markdown image) when they need to see the render. When the user wants to see or explore the drawing themselves, prefer view_dxf (interactive viewer) — if your platform gates it behind user approval, offer it and ask rather than substituting a static render.
| Name | Type | Req | Description |
|---|---|---|---|
| source | string | yes | A publicly reachable http(s) URL, or inline DXF text. A PDF is binary, so it must be a URL — inline PDF bytes are refused. (This is a hosted server — local file paths are not available; use the npx @… |

| width | integer | – | PNG width in pixels (default 1200) |
No output schema declared.
No examples provided.
render_dxf Render a DXF to an image ~345
Render a DXF drawing to a PNG image you can look at. Use this to answer visual questions (what does it look like, where is a feature, does it look right) — it returns an image, not text. For structural facts, prefer describe_dxf. For a PDF use render_pdf; if you do not know the format, use render_doc. Renders the first page/sheet by default; pass `space` (a name from a describe reply's `spaces`) to render another one. Some chat UIs do not display the returned image to the user: for URL sources the result also includes a direct image link — show it (e.g. as a markdown image) when they need to see the render. When the user wants to see or explore the drawing themselves, prefer view_dxf (interactive viewer) — if your platform gates it behind user approval, offer it and ask rather than substituting a static render.

| width | integer | – | PNG width in pixels (default 1200) |
No output schema declared.
No examples provided.
render_pdf Render a PDF to an image ~340
Render a PDF drawing's vector content to a PNG you can look at. Images, shadings, and transparency are not drawn — they are reported by describe_pdf — so this shows line work and text, not a page facsimile. For a DXF use render_dxf; if you do not know the format, use render_doc. Renders the first page/sheet by default; pass `space` (a name from a describe reply's `spaces`) to render another one. Some chat UIs do not display the returned image to the user: for URL sources the result also includes a direct image link — show it (e.g. as a markdown image) when they need to see the render. When the user wants to see or explore the drawing themselves, prefer view_dxf (interactive viewer) — if your platform gates it behind user approval, offer it and ask rather than substituting a static render.
| Name | Type | Req | Description |
|---|---|---|---|
| source | string | yes | A publicly reachable http(s) URL, or inline DXF text. A PDF is binary, so it must be a URL — inline PDF bytes are refused. (This is a hosted server — local file paths are not available; use the npx @… |

| width | integer | – | PNG width in pixels (default 1200) |
No output schema declared.
No examples provided.
view_dxf Open a drawing in the interactive viewer ~281
Open an interactive viewer the user can pan, zoom, and toggle layers in (renders in-chat on MCP Apps-capable hosts). Reads DXF and vector PDF; for a PDF it shows line work and text rather than a page facsimile, so images, shadings, and transparency are absent by design. Use this when the user wants to see or explore the drawing themselves; for your own analysis use a describe_* tool (facts) or a render_* tool (image). The viewer shows only the drawing from this call. Delivery is handled by the widget itself: small drawings are embedded in the result and larger URL-sourced drawings are fetched by the widget through its own tool call — never re-fetch or inline the file for the viewer's sake, and don't blind-retry if the user reports an empty viewer (the viewer posts its actual status back to the conversation context).
| Name | Type | Req | Description |
|---|---|---|---|
| allow_file_open | boolean | – | Show open-file controls in the viewer (default false: viewer is locked to this drawing) |
| source | string | yes | A publicly reachable http(s) URL, or inline DXF text. A PDF is binary, so it must be a URL — inline PDF bytes are refused. (This is a hosted server — local file paths are not available; use the npx @… |
| Name | Type | Req | Description |
|---|---|---|---|
| bounds | – | yes | World-space extents, null for an empty drawing |
| entityCount | integer | yes | – |
| entityTypes | object | yes | Top-level entities per DXF type |
| format | string | yes | Which format was read ("dxf", "pdf") |
| layers | array | yes | – |
| segmentCount | integer | yes | – |
| size | – | yes | Bounding-box size in drawing units, null when empty |
| space | – | yes | Which space this summary is scoped to, or null when it covers the whole drawing (bounds/size then describe spaces[0], the space render returns) |
| spaces | array | yes | Every space in the drawing (a PDF's pages, a DXF's model space and layouts), model space first. These do not sum to entityCount: a DXF sheet's viewports re-show model geometry, so an entity can be dr… |
| texts | array | yes | Unique TEXT/MTEXT strings, blocks included |
| units | string | yes | Drawing-unit label (e.g. "mm"), "" when unitless |
| unsupported | object | yes | Per-kind counts of what was skipped |

What is the Aspicio MCP server?
Aspicio is an MCP server listed in the public MCP registry as io.github.frontsail-ai/aspicio. DXF and PDF/X-4 for AI agents: structured facts, PNG renders, an interactive in-chat viewer. This page covers its hosted endpoint (https://aspicio-api.frontsail.app/mcp).
Is the Aspicio MCP server safe to use?
Aspicio scores 81 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 Aspicio MCP server expose?
Aspicio exposes 8 tools: describe_dxf, render_dxf, describe_pdf, render_pdf, describe_doc, and 3 more. Their descriptions and schemas cost roughly 2,223 tokens of context every time the server is loaded.
Does the Aspicio MCP server require authentication?
No. We connected to Aspicio without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Aspicio MCP server still maintained?
Aspicio is still listed as active in the MCP registry. We last reached this channel on 1 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
