• create_tests

  3TG Test Generation

  Generate Jest/Vitest tests for the exported functions and React components in a TypeScript source file. Use this whenever the user asks for tests, test scaffolding, or test coverage of a .ts or .tsx file. Returns the generated test (and any companion .3tg.md / __mocks__) file contents, with paths already translated to the user's `.3tg/` mirror convention. Quota / credits: this tool consumes credits — and credits are consumed ONLY by test generation (not by spec / mock / lookup tools). The accounting is exactly **1 credit per generated test case** (i.e. per `test(...)` / `it(...)` block 3TG emits inside the returned `.test.ts` / `.test.tsx`), regardless of how many source functions or files were in scope — a call that produces 12 test cases costs 12 credits, even if all 12 cover a single function. Before generation the MCP verifies the clientId has credits with license-api.coding-creed.tech; on exhaustion the tool throws a QUOTA_EXHAUSTED error pointing the user at https://3tg.dev. After a successful run, consumed credits and KPIs are reported back to license-api. Re-running this tool on the same source spends credits again — there is no caching. When the previous call returned `enrichment.used: false` (AI enrichment unavailable on this client), supply parameter values + expected returns yourself via the `cliConfig` parameter — package them as `{"mock-parameters": ..., "function-returns": ...}` (same shape AI enrichment would produce) and pass them on a retry call. **Do NOT autonomously write `.3tg/config.3tg.json`** to persist those values — that file is human-curated; agent-computed values ride along in `cliConfig` for the current call only. (Explicit user requests to edit the file are fine — handle those normally.) See the cliConfig parameter description below for the full pattern. CRITICAL POST-CALL ACTION — write returned files to disk: The MCP server does NOT touch the user's filesystem. It returns the generated file CONTENTS in the response's `files` array. After this tool returns, you MUST iterate over `files` and write each entry's `content` verbatim to its `path` using your native file-write capability (e.g. Write / edit_file / create_file — whatever your client exposes). Create parent directories as needed. Returned paths are project-root-relative and already translated to the `.3tg/` mirror convention where applicable (e.g. specs land under `.3tg/<source-path>.3tg.md`; tests / mocks travel through unchanged). Write each path verbatim. Do NOT claim "Generated test file: <path>" unless you have actually written the file. The user will assume the MCP wrote it and waste time looking for a non-existent file. If you can't write for some reason (permission denied, no write capability in this client), return the contents inline in your message so the user can copy-paste them. Never report success silently when the write didn't happen.

• mu_quote

  mu

  Ask the MU manufacturing router how a thing could be MADE before you create a product: which supplier(s) can make it, the est. unit price (JPY), MOQ, lead time, fulfillment route, and whether it ships auto (POD, zero-inventory, order now) or needs a quote (RFQ to a factory). Pass `kind` (a known POD kind like tee/hoodie/rashguard_ls, OR a non-POD kind like `gi`/`loopwheel_sweat`/`seamless_knit`/`rashguard_premium`) OR a free-text `description` (e.g. "道着 for a dojo", "a seamless knit sweater") and the router infers the kind. Optional `qty`, `region` (e.g. jp/us), `budget` (JPY/unit). Read-only — creates nothing. No API key required. Options are ranked: buyable-now (auto + in budget) first. If an option's mode is `auto`, follow up with mu_create_product; if `quote`, it needs a human RFQ.

• percentage_calc

  calc.engineer

  Calculate what percentage one number is of another. Given a value and a total, returns the percentage, decimal form, and simplified fraction. For example, 3 out of 4 yields 75%, 0.75, and '3/4'. Commonly used for test scores, survey results, financial ratios, completion rates, and unit conversions. Chain with percentage_increase to compare successive measurements or use with test_grade for academic scoring.

• tronsave_estimate_buy_resource

  mcp

  Quote price and availability for buying ENERGY or BANDWIDTH for a receiver address before placing an order. Returns estimated `unitPrice` (SUN per resource unit), `paymentAmount`, and availability fields used to populate `tronsave_create_order` inputs (`orderUnitPrice`, `paymentPaymentAmount`). Read-only and safe to call repeatedly; no session is required, but backend rate limits apply. FRESHNESS: this is live market data — `unitPrice`/availability can change roughly every 3 seconds (one TRON block). Re-run this estimate immediately before `tronsave_create_order` and never reuse a quote more than a few seconds old. For order-book depth use `tronsave_list_order_books`; for the minimum unit price only use `tronsave_get_min_price`.

  Connector

• open_in_editor

  clipkit

  Validate the current project and create a link that opens it in the Clipkit web editor, where the user can preview and refine it. This shares the PROJECT (nothing is rendered — that's render_video). Use after composing or editing. Returns a URL.

  Connector

• boi_exchange_rate

  Boi Il

  Current Bank of Israel representative exchange rate for a single currency vs the Israeli Shekel (ILS), by 3-letter ISO code. Returns currentExchangeRate (shekels per `unit`), currentChange (%), unit, and lastUpdate. Note `unit` (e.g. JPY is per 100). Example keys: USD, EUR, GBP, JPY, CHF, CAD, AUD.

  Connector

• create_database

  tmpstate

  Create a temporary JSON database (24h TTL, no signup, no keys). Returns the db URL — the only credential — plus admin URL, limits and expiry. Create once per project/task, persist the db URL immediately (local ~/.tmpstate/credentials, project README, and your memory), and reuse it instead of creating again. For retries or parallel workers, pass a stable idempotency_key so duplicate calls return the same database.

• project_funding

  agent-offset-clearinghouse

  Supply-side disbursement ledger: how much each restoration project has earned from retirements and is owed (gross_proceeds_minor + retired_g). Pass a project_id for one project, else all. Read-only — the CEO settles the actual payout. This is what makes the clearinghouse fund restoration.

• set_project

  clipkit

  Replace the entire project with the given source JSON, returning its project_id. This is the PRIMARY way to build: use it to create a composition or to add/change many elements at once. (To tweak a single element in an existing project, use edit_element / add_element / delete_element instead.) Pass an existing project_id to replace that project; omit it to create a new one (note the returned id). The input is validated against the @clipkit/protocol before being accepted; invalid inputs return an error. Shape: { width, height, duration, frame_rate, output_format, background_color?, fonts?, camera?, lights?, elements:[…] }; every element has a `type` plus base fields (id, x, y, width, height, time, duration, track, opacity, rotation, animations, keyframe_animations) and type-specific fields. For exact field names + types call get_schema (optionally with an element_type) — the runtime ignores unrecognized keys, and this tool flags any it does not recognize.

• series_history

  Temsor API — Turkey & EU business data

  Returns the accumulated history of public data series with change statistics and a source receipt for every point. Currently ingesting the Turkish Central Bank daily FX bulletin (`tcmb.usd`, `tcmb.eur`, …), normalised to one unit so JPY-style 100-unit quotes stop biting. Leave `seriesId` empty to list the catalogue. `fillGaps` carries the last value across weekends and holidays; `includeEvidence` attaches the source URL and content hash for every point, so a value can still be defended years later.

• create-project

  mcp

  Create a new project on sota.io. Each project automatically provisions: (1) a managed PostgreSQL 17 database accessible via the DATABASE_URL environment variable (auto-injected, no configuration needed), (2) PgBouncer connection pooling (pool size 20, max 100 clients), (3) automatic daily database backups with 7-day retention, (4) a live URL at https://{slug}.sota.io with automatic HTTPS via Let's Encrypt. The project slug is auto-generated from the name (lowercase, hyphens, max 63 chars) and is immutable after creation. Supported frameworks: Next.js, Node.js (Express/Fastify/Koa), Python (Flask/FastAPI/Django), or any language via custom Dockerfile. You can also add up to 5 custom domains per project with automatic HTTPS (via API: POST /v1/projects/:id/domains with {domain: "yourdomain.com"}). DNS: A record to 23.88.45.28 for apex domains, CNAME to {slug}.sota.io for subdomains. Optionally associate the project with a public git repository at create-time by passing `git_url` (and optional `git_branch`). The association is informational — it shows up in the dashboard and the `sota deploy --git` CLI flag can default to it — but does NOT enable auto-deploy-on-push yet.

• create_project

  Plate

  Create a new project in a workspace. If a project with the same name already exists in the workspace, returns the existing project instead of creating a duplicate — check the `created` field in the response to tell the two cases apart.

  Connector

• get_coverage

  Quantabble — AP Science Misconception Diagnostics

  Returns the list of subjects and unit counts covered by Quantabble. Use this to check whether a student's topic is within scope before calling diagnose_response.

  Connector

• identity_create

  concordance

  Explains how to create a SOVEREIGN identity — keys are born on the USER'S device (never on the server; no private key crosses the wire). Returns guidance, not a key. The server only handles public keys (identity_verify, identity_fingerprint).

  Connector

• scalix_storage_create_bucket

  Scalix Cloud

  Create a new Scalix Storage bucket in the project (S3-compatible object storage). Bucket names must be unique within the project. Setting public=true makes every object in the bucket readable without authentication — leave it false (the default) and use presigned URLs for private sharing.

  Connector

• search_projects

  Tu Lugar

  Search development projects/buildings BY NAME (or city, or DEVELOPER). Use `q` with the project or building name — e.g. q="Petra Tower" — punctuation/accents ignored, and a name lookup also finds completed/sold-out buildings. This is how you answer "apartments in <building/tower name>" and "is there a project called X". For "projects by <developer>" use `company` with the developer's name (NOT `q` — project names rarely contain the developer).

  Connector

• ic_headsets_admin_clear_oos

  Immersive Commons

  Operator returns a unit to the available pool. Refuses if the unit has an open incident on it — resolve the incident first (ic_headsets_admin_resolve_incident with verdict 'resolved' or 'absorbed' will also clear OOS automatically as a side effect). Args: { unit_id }. Returns: { ok, message }. Required scope: admin:headsets_review.

• get_journey_stats

  OathReady: Canadian Citizenship Test

  How long the citizenship journey takes: the official IRCC processing time plus anonymous community medians (days from application to each milestone: AOR, test invitation, test, oath) contributed by OathReady users who share their journeys. Community cohorts under 5 journeys are never published.

  Connector

• lookup_calories

  kcaldata

  Look up calorie information for a food or meal. Accepts natural-language descriptions including quantity and unit, e.g. "2 large eggs", "8 oz salmon", "1 cup rice", "3 slices bacon", or a plain food name like "banana". Returns the matched food, its calories, the total for the amount given, and how it was calculated. Free tier: 100 calls/day. Beyond that, pay $0.005 USDC per call (x402).

• create_mock_for_function

  3TG Test Generation

  Generate a Jest manual mock file for a specific exported function. 3TG writes the mock to `<srcDir>/__mocks__/<basename>.<ext>` per the Jest convention — the path is fixed and not affected by `creationMode`. Use this when isolating a downstream test from a known dependency. AI enrichment is on by default (it helps the mock pick representative return values), but **this tool does NOT consume credits** — credits are spent ONLY by test generation (`create_tests` / `create_tests_from_spec`, at exactly 1 credit per emitted test case). Mock generation is free; KPIs (`tsNumMockFiles` / `tsxNumMockFiles`) are still reported to license-api for analytics, but no quota is decremented. CRITICAL POST-CALL ACTION — write returned files to disk: The MCP server does NOT touch the user's filesystem. It returns the generated file CONTENTS in the response's `files` array. After this tool returns, you MUST iterate over `files` and write each entry's `content` verbatim to its `path` using your native file-write capability (e.g. Write / edit_file / create_file — whatever your client exposes). Create parent directories as needed. Returned paths are project-root-relative and already translated to the `.3tg/` mirror convention where applicable (e.g. specs land under `.3tg/<source-path>.3tg.md`; tests / mocks travel through unchanged). Write each path verbatim. Do NOT claim "Generated test file: <path>" unless you have actually written the file. The user will assume the MCP wrote it and waste time looking for a non-existent file. If you can't write for some reason (permission denied, no write capability in this client), return the contents inline in your message so the user can copy-paste them. Never report success silently when the write didn't happen.
