Wolfram Alpha MCP — computational, factual, and quantitative queries.

Tools

• short_answer(query, units?) — single terse plain-text answer.
• full_query(query, units?, include_pods?, format?) — structured pods.
• wolfram_compute(code, time_constraint_seconds?) — evaluate Wolfram Language code in a real kernel (keyless; proxies Wolfram’s hosted MCP evaluator).

Auth

• Platform key: gateway env PLATFORM_WOLFRAM_KEY (short_answer / full_query only).
• BYO: ?_apiKey=<appid> after registering at https://developer.wolframalpha.com (free 2,000/mo).
• wolfram_compute needs no key.

Evaluation semantics (triage note)

wolfram_compute transmits code verbatim — as a JSON field, no URL encoding anywhere in the path — and the kernel evaluates exactly what was sent. A result that disagrees with the intent of a question is almost certainly a bug in the submitted code, not in transmission or the kernel. Before filing a tool bug, echo the parse back through the tool itself:

wolfram_compute({ code: "ToString[Hold[<the code>], InputForm]" })

Worked incident (fleet #422, 2026-08-17): Length[Select[Permutations[Range[5]], And@@Thread[#!=Range[5]]&]] was reported as “returns 119, should be 44 (derangements of 5)”. 119 is the correct value of that code: on two concrete lists, perm != Range[5] evaluates eagerly to a single True/False (whole-list Unequal) before Thread can split it elementwise, so the predicate collapses to “permutation ≠ identity” and counts 120 − 1 = 119. The elementwise form And @@ MapThread[Unequal, {#, Range[5]}] & (or just Subfactorial[5]) returns 44 through the same tool.
