Nobody here has read this server's code, because it publishes none. The description above is the maker's own, from the registry. A connection test shows whether it answers and what tools it says it has; it never calls a tool, so it cannot show what one does with your data.
Where it sits in the directory's order
What can be seen from outside, weighed as the directory publishes.
Observable signals: 20 of 100 points (at most 60 here)
| Input | Points | What was seen |
|---|---|---|
| Source published | held at 0 | No entry here publishes source: that is what puts it in this directory. |
| Licence stated | held at 0 | With no files, there is nothing for a licence to be stated in or held against. |
| Advisory state | held at 0 | Advisory databases index packages, and these entries publish none, so there is nothing to look up. |
| Auth declared | 0 of 15 | The registry entry declares no key. That is what it declares, not a finding that it has no protection. |

Connection test
The MCP handshake, then a request for the tool list, with no key and no data of yours. Run nightly, and by anyone, at most once every ten minutes per server.
It completed the handshake and listed 10 tools.

The tools it lists (10, as of 5 days ago)
The tool-description rules found nothing in these descriptions. They look for instructions aimed at a model and for hidden characters; they cannot see what a tool does when it runs.
list_calculatorsList available calculators, optionally filtered by category
get_calculator_schemaGet the input schema for a specific calculator
calculateRun a calculation and get results + prefilled URL
generate_prefilled_urlGenerate a prefilled URL without running calculation
calculate_casEvaluate one or more headless CAS expressions server-side (MCP-only numeric mode). Unsupported expressions return a GUI handoff link.
calculate_cas_headlessAlias of calculate_cas. Headless MCP-only CAS evaluator; if unsupported features are requested, returns GUI handoff details.
create_sessionCreate a new interactive session for any calculator and return the session URL
get_session_stateRetrieve the current field values, computation transcript, and pending message queue for an active session
push_session_actionPush actions into a session's message queue (set fields, submit computation, trigger plot, etc.)
close_sessionClose a session and optionally persist a snapshot of its final state
How this entry becomes a listing
For the maker. The catalogue lists what it can read, and this server publishes nothing to read yet. There are two routes, and only the first is open today.
Publish the source Open today
- Put the server's source in a public repository on github.com, with a licence.
- Keep a server.json in that repository naming this server,
com.mcpcalc/calculator, and declare the repository in it:"repository": { "url": "https://github.com/owner/repo", "source": "github" }, adding"subfolder"when the server lives in a folder. - Publish that version to the official MCP registry.
- The nightly registry sweep records the declaration. This page stays, dated, and says the source is declared but not yet read.
- The catalogue reads declared repositories at a pinned commit, in batches run by hand, and lists the servers that meet the batch's rules (among them a server.json at that commit naming the server, an https endpoint and a licence). When it lists this server, this page links to the listing. There is no schedule, so no date can be promised.
