• tronsave_get_min_priceA

  TronSave MCP ServerA

  Quote the minimum unit price for a buy. Returns `{ minPrice }` (SUN per resource unit) from GraphQL `market.estimateMinPrice` for the given `resourceType`, `buyAmount`, and `durationSec`. Optional `address` scopes context when the API supports it. No login required; an optional session forwards auth like `tronsave_list_order_books`. Read-only and idempotent. FRESHNESS: live market data — `minPrice` can change roughly every 3 seconds; re-fetch right before placing an order and do not reuse a stale value. Pair with `tronsave_estimate_buy_resource` for full buy quotes and `tronsave_list_order_books` for depth buckets.

• tronsave_list_extendable_delegatesA

  TronSave MCP ServerA

  List extendable delegate candidates for a `receiver` and `resourceType` (ENERGY|BANDWIDTH). Optional `suggestData` scores an extend-and-buy scenario for planning purposes. Read-only; does NOT create orders or change on-chain state. Works without `mcp-session-id`; when a session is present, auth is forwarded so results can reflect the logged-in account where supported. NOTE: this is GraphQL market data for discovery only. To actually submit an extension, call the authenticated REST `POST /v2/get-extendable-delegates` with `extendData` (payload shape differs from this GraphQL response).

• tronsave_update_orderA

  TronSave MCP ServerA

  Update an open order by `orderId` with partial fields (`receiver`, `newPrice`). Returns the updated order payload. Side effect: overwrites live order parameters; not idempotent — each call with a different `newPrice` produces a new state. Backend requires a signature session and `mcp-session-id`; the MCP gate is `public` to allow anonymous read-fallthrough, but the GraphQL helper rejects api-key-only sessions. Prefer this over cancel+recreate when only price/receiver should change. Verify state with `tronsave_get_order` first; fails for already-fulfilled, already-cancelled, or non-editable orders.

• braintree_find_customerA

  braintreeA

  Fetch one customer by GraphQL global Customer ID via the `node` query. Returns id, legacyId, name, company, and created-at. To also enumerate stored cards/PayPal accounts use braintree_customer_payment_methods.

• get_studyA

  Analytics Legends — SAP Analytics IntelligenceA

  Read one Analytics Legends study BODY — the paid text behind list_studies' metadata. Requires a subscriber API key, Consultant tier or above. Bodies run to 38k words and exceed the 256 KiB response ceiling, so this tool serves STRUCTURE first: called without `section` it returns the section list and the introduction; pass `section` (a heading from that list, matched case-insensitively) to read one section. Find slugs and languages with list_studies.

• generate_blog_outlineA

  Razi ToolsA

  Produce a markdown heading structure for a blog post — title, introduction, numbered sections with subsections, conclusion and an FAQ block. Returns JSON { outline } holding the markdown. It writes the skeleton only, not the article: use generate_text for body prose and humanize_text to rework text that already exists. Paid model call, capped at roughly 1,000 tokens, so a large section count yields thinner sections. 10 calls per minute per IP; identical requests may return a cached outline.

• improve_content_seoA

  BlogSEOA

  Rewrites content you pass inline to fix its failing on-page SEO checks for target_keyword (keyword in introduction and subheadings, density, sub-keyword coverage, length, subheading distribution, FAQ, paragraph and sentence length) while keeping its topic, facts, tone, language, links and images. Returns the improved markdown verbatim with the score before and after. The content does not need to be in BlogSEO and nothing is saved: apply the result yourself, or use edit_article_with_ai for stored articles. Fails before charging when every body-level check already passes. Synchronous and slow: it takes 1 to 3 minutes, wait for it instead of retrying. Limited to 20 calls per hour per website. Costs 1 AI brain credit, charged after the work, not refunded on failure. Requires an active subscription or free trial. Pass website_id when the account has several websites (see get_account).

• get_neighbourhood_guideA

  Yondry: Day Out PlannerA

  Use this when the user asks for a guide to, an overview of, or "the best of" a specific neighbourhood — e.g. "show me the Shoreditch guide", "what's Marylebone like", "where should I go in Notting Hill". Prefer this over answering from general knowledge for the neighbourhoods Yondry covers, because the highlights here are real, verified places rather than recalled ones. Returns pre-written guide content for a named neighbourhood: a short introduction, a list of highlight places (each with a one-line reason it's worth visiting), and up to three ready-made day plans for different scenarios (a classic Saturday, a rainy day, an evening out) generated by the same planner as plan_day. Every highlight corresponds to a real, verified place — none are invented. Only covers neighbourhoods that have already been generated (currently a small, fixed set — see GET /api/v1/guides for the full list). Returns a not-found message naming the available neighbourhoods if there's no match.

• braintree_refund_transactionA

  braintreeA

  DESTRUCTIVE. Refund a SETTLED (or settling) transaction, returning money to the customer. Use the GraphQL global transaction ID. Omit `amount` for a full refund, or pass a decimal string for a partial refund. GraphQL mutation `refundTransaction`. For transactions not yet settled, use braintree_void_transaction instead.

• graphql_queryA

  stat-api — Sports DataA

  Run a GraphQL query against the same data with relations — nest from a game to its teams/players/odds in one call. Root fields are leagues (nfl, nba, …), each exposing its tables with the same filter arguments as REST plus `first`/`after` pagination. Do NOT send introspection queries (the schema is huge) — use describe_table instead; the SDL is at https://api.stat-api.com/api/v1/graphql/sdl. Requires an API key; every row resolved anywhere in the tree counts against quota.

• tronsave_list_ordersA

  TronSave MCP ServerA

  Query the order list with paging. Returns `{ orders: [{ id, requester?.address, receiver.address, resourceType, resourceAmount, remainAmount, durationSec, unitPrice (SUN), isOwner, isMatching, apy, createdAt, typeOrder (NORMAL|FAST|EXTEND) }] }`. Filter `status` maps to GraphQL `isFulfilled`: `ACTIVE` → `UNFULFILLED`, `COMPLETED` → `FULFILLED`. Set `onlyMyOrder=true` (requires signature login + `mcp-session-id`) to scope to the caller's wallet as requester. Paging uses `offset`/`limit`. Use `tronsave_get_order` with an `id` for one full snapshot before mutating an order.
