• ios_set_device_languageA

  Robot Actions — Remote Device ControlA

  Change the iOS device's system language and / or locale (persistent, affects every app). iOS may relaunch SpringBoard to apply the change — expect a 5-10s flicker, and the value can take a few seconds to read back. Pass a BASE language code ("fr", not "fr-CA"): iOS reports a region-qualified language but refuses to set one, so a regional code is split into its base language plus a locale automatically. For per-app testing without changing the whole device, prefer ios_launch_app_in_language.

• unlocode_lookupA

  FreightUtils MCP ServerA

  Search 116,232 UN/LOCODE transport locations worldwide — ports, airports, rail and road terminals, inland container depots and border crossings. Codes are 5 characters: a 2-letter ISO country code + a 3-character location code (GBLHR = London Heathrow, NLRTM = Rotterdam). Provide code for an exact record, or query (name search, min 2 chars) optionally narrowed by country and function_type; limit caps results (default 20, max 100). Behavior: read-only; exact code hits are provenance-based while fuzzy name hits report match quality via the envelope's confidence (basis match_quality); an unknown code errors with a not-found message. Rate-limited (anonymous use: 25 requests/day per IP): a 429 error body carries retry_after_seconds and a Retry-After header — back off and retry, or call get_subscribe_link for higher limits. Returns: the location record(s) — code, name and name_ascii, country, subdivision, functions[], status, coordinates {lat, lon} and iata_code where assigned — under result, plus confidence, _source and citation (the FreightUtils v1 response envelope). Limitations: an administrative code list (UNECE UN/LOCODE 2025-1) — confirm operational status and coordinates with the port or authority before critical use. Related: airport_lookup (airport-specific records including ICAO codes), nearest_airport (find airports by coordinates).

• echo_facility_searchA

  Epa EchoA

  Search EPA-regulated facilities by name, state, ZIP code, city, or industry code. facility_name uses a case-insensitive starts-with match; prepend % for a contains search (e.g., "%Exxon%" finds any facility with "Exxon" in its name). Combine at least two filters — a bare state is rejected upstream for large states ({state: "TX"} alone matches ~344,000 facilities and errors). Good queries: {facility_name: "%Exxon%", state: "TX"}, {city: "Baytown", state: "TX"}, {zip: "94025"}, {naics: "3251", state: "TX"}. Returns facility IDs, addresses, lat/long, compliance status, inspection/enforcement counts, and total penalties.

• find_examplesA

  SenzingA

  Find working SOURCE CODE examples from 42 indexed Senzing GitHub repositories. REQUIRED: either `query` (string, for search) or `repo` with `file_path` or `list_files=true` — the call WILL FAIL without one. Three modes: (1) Search: pass `query` to find examples across all repos, (2) File listing: pass `repo` + `list_files=true`, (3) File retrieval: pass `repo` + `file_path`. Indexes source code (.py, .java, .cs, .rs, .ts, .js) and READMEs — NOT build/data files. For sample data, use get_sample_data. Covers Python, Java, C# (official SDKs) plus Rust and TypeScript/Node.js (community-maintained wrappers, not official) SDK patterns: initialization, ingestion, search, redo, configuration, message queues, REST APIs. Use max_lines to limit large files. Returns GitHub raw URLs for file retrieval.

• explain_compliance_errorA

  ApierA

  Resolve a structured Apier compliance error code into a Norwegian-bokmål Explanation envelope: summary, bokmål why, ordered fix_steps, optional documentation link + legal_basis, and an optional handover block (who / where / what / why) for errors a human must resolve (e.g. AUTH_INSUFFICIENT_ROLE, AUTH_NO_DELEGATION, SCOPE_MISSING) — agent-resolvable errors ship `handover: null`. Accepts any code from the closed EXPLAINER_ERROR_CODES catalogue — pass whatever code an Apier endpoint returned in an error envelope. Optional flat context_org_number / context_scope / context_role / context_field / context_upstream_system strings carry placeholder values interpolated into the bokmål text; missing values fall back to 'ukjent <noun>'. Failure modes: VALIDATION_FAILED on an unknown code; SCOPE_INSUFFICIENT (needs read:rulebook). For a company's live obligations rather than an error explanation, use get_company_obligations instead. No API key? Bearer apier_sandbox_test_<suffix> (fresh suffix) serves synthetic fixtures; org numbers: GET /api/v1/sandbox/fixtures. Docs: https://www.apier.no/docs/guides/error-handling

  webbersites-x402-data-apiA

  LLM CODE DEBUGGING — POST {code, error} and get a diagnosis: what is wrong, the root cause, and a concrete fix with corrected code. Paste the failing snippet plus the error message or stack trace; any language, up to 20,000 chars combined. Optional {language} and {context} ('happens only on the second call'). Fast cheap LLM under the hood. Want deterministic no-AI lint instead? POST /api/lint/:language ($0.002). ($0.01 per call, paid via x402)

• klyo_game_diagnosticsA

  klyo games: publish HTML5 browser gamesA

  Eyes inside the game: for a package in the waiting room (`upload_id`) or a game in the catalogue (`slug`) it returns the files the game asked for that are missing from the package, and the JavaScript errors from the preview in the browser, in the order they happened. Also: the package check result (size, third-party ads, malicious code, missing klyo kit), ready conclusions in `wnioski`, and `dopasowanie`: the fit measurement from publishing on four screens (phone portrait and landscape with touch, tablet, desktop): `uwagi[]` with the codes `przewija` (page scrolls) | `maly_ekran` (screen too small) | `maly_tekst` (text too small) | `ciezka` (too heavy) | `dlugie_wczytanie` (long load) | `niski_fps` (low frame rate) | `male_cele_dotyku` (small touch targets) | `przycisk_bez_nazwy` (button without a name), `dotyk_nasluch` and `zrzut` thumbnails; `null` = the game has not been measured yet (a measurement starts with every version release). Read-only. YOUR BROWSER IS THE EYE HERE: we do not keep a browser farm and do not need one. Open the preview address on YOUR side (Playwright, Chrome, a phone), really play (click, swipe, wait for the second level) and our sensor on that page reports everything that crashed. Then ask with this tool. Order: open, play, ask; the other way round gives an empty answer, because errors are collected only once the game runs. Add `?s=<your marker>` to the address and pass `sesja` with the same value to get only the errors from your own run. NO BROWSER (a conversation in claude.ai or ChatGPT)? Pass `zmierz: true` for a package or a waiting version: we open the preview for you, collect errors and thumbnails of four screens (`zrzut_adres`); one measurement runs at a time per account and one more waits in the queue and starts by itself; 6 per hour, a full measurement counts as two. Add `pelny: true` for the production profile (a slow phone and every declared language). A game with a waiting version (workshop) shows its files, errors and premium review (`przeglad`). Examples: • Why does my game show a white screen? • Check the errors in the package preview • What is missing from the lantern-thief package?

• decode_templateA

  Guild Wars 1 Build CompilerA

  Decode an in-game GW1 skill template code (e.g. "OwpiMypMBg1cxcBAMBdmtIKAA") into professions, attribute allocations and the 8 skills with their stats and descriptions. Whitespace and line wraps in the pasted code are tolerated. This decodes a SINGLE build code; for a multi-hero paw-ned2 team blob, use decode_pawned_team instead.

• encode_templateA

  Guild Wars 1 Build CompilerA

  Compile a build (professions, attributes, 8 skills by exact English name) into an official in-game template code. The build is validated first; on rule violations the errors are returned instead of a code. Unknown skill names return closest-match suggestions. IMPORTANT: template codes MUST come from this tool — never write or guess a code by hand, hand-written codes are invalid in-game. If unsure, verify any code with decode_template.

  Begin TOTP enrolment. Returns a fresh ``secret`` + ``otpauth_uri`` + a signed ``ticket``. NOTHING is persisted yet — feed ``secret`` to any RFC-6238 TOTP library, then call ``colony_2fa_confirm`` with the secret, ticket, and a generated code to turn 2FA on (that call returns your recovery codes). Errors: ``AUTH_2FA_ALREADY_ENABLED``.

  webbersites-x402-data-apiA

  JavaScript / Node lint: POST {code}, get the bugs back with line numbers. Syntax errors come from the real V8 parser (compile-only — code is never executed), plus deterministic checks: loose == coercion, assignment in conditions, comparisons with NaN, const reassignment (runtime TypeError), var pitfalls, unused variables, leftover console.log.

  ai-netcafeA

  Convert a SQL statement from one dialect to another — mysql, postgres, sqlite, tsql, oracle, snowflake, bigquery, redshift, spark, hive, presto, trino, duckdb, clickhouse, databricks, doris, starrocks and more. Deterministic parser (sqlglot), not an LLM: the same input always produces the same output, and syntax errors come back with the exact line and column. Use it when migrating queries between databases or debugging dialect-specific syntax.

• ai_code_smell_scanA

  Moltline Code Review & AI-Code VerifierA

  Flag the tells of unreviewed AI-generated code in a source file. FREE. Detects comments that restate the next line, leaked assistant preambles, placeholder TODOs, shipped 'Example usage' blocks, over-broad try/except that swallows errors, and auto-named identifiers. Typical input {"code": "<file contents>"} returns {"reviewed_confidence": 0-100, "hits": [{"smell": "...", "evidence": "<quoted snippet>"}], "reading": "...", "note": "..."}. Use on a full source file suspected of unreviewed machine authorship. Not on a diff (review_diff), and the result is a signal to check, not proof of authorship. Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry.
