## 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 2026-10-07.

- **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**: 83/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 367 tokens (~122/item across 3 items; 3 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 20/100
  - Stability observed for 6 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 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 (67% 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 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 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).

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-10-07 (score 78, +1)

No change was recorded against any check on this day. Stability & Change Management went from 13 to 20. That category is still filling its 30-day observation window: 4 days of observed history at the previous scan, 6 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (3)

### `make_plot_link` (~137 tokens)

Make a Graph Paper link

Check a Graph Paper plot document and return the link that opens it. The link opens the plot as an editable draft in Graph Paper (https://graph-paper.io); the reader needs no account. Give the document as a JSON object in the format of get_plot_format. If the document has errors, the result lists each one with the path of the field and what to change, and no link; fix them and call the tool again. Warnings name the keys that were ignored.

Input parameters:

- `document` (object, required): The plot document: a JSON object with at least "title" and "series". See get_plot_format and list_examples.

Output parameters:

- `category` (string)
- `dimension` (integer)
- `errors` (array)
- `note` (string): With ok true: the formulas were not computed, and what to ask the person when a row does not work.
- `ok` (boolean): True when the document is valid and url is given.
- `rows` (object): How many rows of each kind the document has.
- `title` (string)
- `url` (string): The link that opens the document.
- `warnings` (array)

### `get_plot_format` (~109 tokens)

Read the plot document format

Return the reference of the Graph Paper plot document format, as Markdown: every field of a plot document, the series types, the limits, and complete examples. Give section to get one section only (a heading of the page, such as "Variables" or "2D Series Types"); an unknown section returns the list of headings. Read it before you write a document for make_plot_link.

Input parameters:

- `section` (string): A heading of the format page. Leave it out for the whole page.

### `list_examples` (~50 tokens)

List example plot documents

Return the example plot documents of the Graph Paper format page, each with its title and its JSON. Each one is a valid document that make_plot_link accepts; start from the one closest to what you want.

Output parameters:

- `examples` (array)

## Common questions

### What is the Graph Paper MCP server?

Graph Paper is an MCP server listed in the public MCP registry as io.graph-paper/graph-paper. Check a plot document and get a link that opens it in Graph Paper. No account, no key. This page covers its hosted endpoint (https://graph-paper.io/mcp).

### Is the Graph Paper MCP server safe to use?

Graph Paper scores 78 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 Graph Paper MCP server expose?

Graph Paper exposes 3 tools: make_plot_link, get_plot_format, list_examples. Their descriptions and schemas cost roughly 296 tokens of context every time the server is loaded.

### Does the Graph Paper MCP server require authentication?

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

### Is the Graph Paper MCP server still maintained?

Graph Paper is still listed as active in the MCP registry. We last reached this channel on 7 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
