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. How we score → Why this is hard to score →
Supply Chain Security88
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- Install-script risk not yet assessed.Unverified
- No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency48
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Build provenance not yet verified. View diagnostics → Unverified
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 2 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability78
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 510 tokens (~102/item across 5 items; 5 tools + 0 resources), lean.Pass
- 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 (20% 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 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
Every change we have recorded for this component, newest first. Security-relevant changes are always shown. ▲ marks a change for the better, ▼ a change for the worse; unmarked changes are neutral.

No change was recorded against any check on this day. Stability & Change Management went from 93 to 97. That category is still filling its 30-day observation window: 28 days of observed history at the previous scan, 29 at this one. The score rises as the window fills, whether or not the server changes.

Captured 4 Nov 2026 · Analysed nuget/MatPlotLibNet.Mcp@1.18.1
Provenance Inconclusive
We could not complete the check, so nothing is claimed either way. This is a gap on our side, not a finding about the package.

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 →
chart_data_table Read a chart's data as a table ~109
Returns the DATA of a chart spec: markdown tables to read - the numbers the picture is drawn from, which an image cannot be read for - and the same values as structured content, so they can be used without parsing the markdown. One table per group of series that share an x. Long charts are refused with the limit in the message; save the chart and read the file instead.
| Name | Type | Req | Description |
|---|---|---|---|
| spec | – | yes | The chart spec: MatPlotLibNet figure JSON, the same document render_chart takes. |
| Name | Type | Req | Description |
|---|---|---|---|
| tables | array | yes | – |
No examples provided.
describe_chart_schema Describe the chart spec ~68
Describes the fields of a chart spec, with a worked example. Pass a chart type to see the fields of that type; omit it for the shape of the whole spec.
| Name | Type | Req | Description |
|---|---|---|---|
| seriesType | string|null | – | A chart type from list_chart_types, or omit for the whole spec. |
No output schema declared.
No examples provided.
list_chart_types List the chart types ~26
Lists the chart types a spec may name in a series' "type" field.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
render_chart Render a chart as an image ~147
Renders a chart from a MatPlotLibNet figure-JSON spec and returns it as a PNG image, with a short text summary of what was drawn. Call describe_chart_schema for the shape of the spec and list_chart_types for the chart types. For SVG or PDF, use save_chart — they are too large to return inline.
| Name | Type | Req | Description |
|---|---|---|---|
| format | string | – | The image format. Only png can be returned inline. |
| spec | – | yes | The chart spec: MatPlotLibNet figure JSON, e.g. {"width":800,"height":600,"subPlots":[{"series":[{"type":"line","xData":[1,2],"yData":[3,4]}]}]} |
No output schema declared.
No examples provided.
save_chart Save a chart to a file ~160
Renders a chart from a MatPlotLibNet figure-JSON spec and writes it to a file, returning the path it wrote. Use this for SVG and PDF, and for images too large to return inline. The file is written under the server's output directory; an existing file is kept unless overwrite is true.
| Name | Type | Req | Description |
|---|---|---|---|
| format | string | yes | The output format; it must match the file extension. |
| overwrite | boolean | – | Replace the file when it already exists. Off by default: the server never destroys a file it did not make. |
| path | string | yes | File name or relative path, with the extension of the format (.png, .svg or .pdf). |
| spec | – | yes | The chart spec: MatPlotLibNet figure JSON. |
No output schema declared.
No examples provided.

What is the io.github.xkqg/matplotlibnet MCP server?
io.github.xkqg/matplotlibnet is an MCP server listed in the public MCP registry as io.github.xkqg/matplotlibnet. Renders MatPlotLibNet charts to PNG, SVG or PDF from a JSON spec an AI agent writes. This page covers its NuGet package (MatPlotLibNet.Mcp).
Is the io.github.xkqg/matplotlibnet MCP server safe to use?
io.github.xkqg/matplotlibnet scores 82 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 4 November 2026. 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.xkqg/matplotlibnet MCP server expose?
io.github.xkqg/matplotlibnet exposes 5 tools: describe_chart_schema, render_chart, list_chart_types, chart_data_table, save_chart. Their descriptions and schemas cost roughly 510 tokens of context every time the server is loaded.
Is the io.github.xkqg/matplotlibnet MCP server still maintained?
io.github.xkqg/matplotlibnet is still listed as active in the MCP registry. We last reached this channel on 4 November 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.xkqg/matplotlibnet MCP server under?
io.github.xkqg/matplotlibnet declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
