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 Usability83
- AI-judged instruction clarity (excellent).Pass
- Tool/resource definitions use about 367 tokens (~122/item across 3 items; 3 tools + 0 resources), lean.Pass
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management20
- Stability observed for 6 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
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 (67% 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 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 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
How do I install the Graph Paper MCP server?
Graph Paper is a hosted endpoint at https://graph-paper.io/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.

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.
- 7 Oct 26 +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.

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 →
get_plot_format Read the plot document format ~109
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.
| Name | Type | Req | Description |
|---|---|---|---|
| section | string | – | A heading of the format page. Leave it out for the whole page. |
No output schema declared.
No examples provided.
list_examples List example plot documents ~50
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.
Input schema present but exposes no named parameters.
| Name | Type | Req | Description |
|---|---|---|---|
| examples | array | yes | – |
No examples provided.
make_plot_link Make a Graph Paper link ~137
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.
| Name | Type | Req | Description |
|---|---|---|---|
| document | object | yes | The plot document: a JSON object with at least "title" and "series". See get_plot_format and list_examples. |
| Name | Type | Req | Description |
|---|---|---|---|
| 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 | yes | 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. |

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.
