"An introduction to GraphQL" matching MCP tools:

• createImage

  Ludo AI Game Assets

  Generate game-art images from a text prompt alone, selecting an image_type (e.g. sprite) and optionally art_style, perspective, and aspect_ratio. Synchronous: the call blocks until generation finishes and returns an array of image results, each with a url; request n (1-8) to control how many variations come back. Because it generates purely from text it takes no source image, so there is no upload size limit to trip. Credits are charged only on success, scaled to the number of images produced. Use createImage to make new images from scratch; use generateWithStyle to match a reference image's art style, editImage to modify an existing image, and removeBackground to cut out a subject. Pass an optional request_id to tag the results so you can retrieve them later via getImageResults. Requires an API key (user scope). Credits: This endpoint consumes 0.5 credits per result.

• tronsave_sell_order_manual

  Tronsave MCP Testnet

  Manually execute seller-side fulfillment of an existing order with a wallet `signedTx`. Returns the updated order payload after sell. Side effect: broadcasts a market/delegation transaction and may consume balances/resources; not idempotent — each call re-executes. 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. Use only when explicit manual sell is intended; call `tronsave_get_order` first to verify order state before signing.

• emem_entity_link

  emem, the verifiable memory protocol for the physical world

  Record a signed equivalence: bind an alternate label or a stable external id (GERS / OSM / Wikidata) to an existing canonical object so future `emem_entity_resolve` calls on that phrasing converge to the same entity_cid. Builds the shared reference graph that keeps different agents' vocabularies pointing at one identity. When to use: Call when you learn that two phrasings denote the same object ('the north dam' == an existing entity), or to attach an authoritative external id to an object minted from free text. Example arguments: {"entity_token":"emem:entity:0a1b2c3d4e5f60718293","alias":"the north dam"}

• tronsave_get_min_price

  TronSave MCP Server

  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.

  Connector

• tronsave_list_extendable_delegates

  TronSave MCP Server

  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).

  Connector

• tronsave_update_order

  TronSave MCP Server

  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.

• ic_agent_inbox_send_envelope

  Immersive Commons

  Route a typed intent (ping / request_meeting / send_intro) to another IC member's agent inbox. Recipient's policy engine decides what happens — store + notify, store + queue-for-tap, silently drop (blocklist), or refuse (inbox closed). Server-side: sanitizes body (C0 controls / zero-width / NFKC), wraps into the per-intent payload, persists thread + envelope + sender-history + audit, evaluates policy, returns the decision. Scopes per intent: ping → agent:ping (ai-floor+); request_meeting → agent:request_meeting (ic-member+); send_intro → agent:send_intro (ic-member+). send_intro brokers an introduction TO the recipient and requires intro_target_name + body (the intro_pitch) + expected_outcome + consent_target_has_opted_in=true (anti-spam — you MUST have the target's consent). Idempotency: pass `idempotency_key` to make the (token, key) pair cached for 24h. Returns: { ok, envelope_id, thread_id, state, policy_decision }. Recipient inbox closed → mcpError. Blocklisted senders get an opaque ok-shape with random ids (silent-block — no persistence visible to the sender; the audit row is server-side only). PRECHECK: call ic_agent_directory_lookup first — a member whose inbox_status is "closed" (the default for newly-joined members) cannot be reached and this verb will refuse. v1 SHIP note: request_meeting wraps body into context_summary with sensible defaults until the agent-console UI exposes full per-intent args.

• braintree_find_customer

  braintree

  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.

  Connector

• get_company

  Dice MCP

  Retrieve the name and description of the company behind a job, by job ID. Use this tool when users want more detail about a company than search_jobs/get_job_details return (e.g. after finding a job and wanting to know more about the company that posted it). DO NOT use for: searching/discovering companies or jobs by keyword (use search_jobs instead). LLM USAGE INSTRUCTIONS: - The typical flow is: search_jobs to find jobs -> user picks one -> offer to look up the company -> if the user agrees, call this tool with that same job_id (the same guid used for get_job_details; no separate lookup step is needed first). - Do not call this automatically right after get_job_details; ask the user first unless they already explicitly asked for company details. - Not every company has published an employer branding profile, and some profiles are marked not visible by the company. When that happens this tool does NOT raise — it returns a Company with `message` set and empty name/desc. Relay that message to the user (e.g. "Looks like that company hasn't published a public profile.") rather than treating it as an error. Args: job_id: The unique identifier of the job whose company to look up (required). This must be the job's `guid` field from a search_jobs result, NOT its `id` field — `id` is a different, internal identifier that this tool does not accept. Returns: Company: Contains: - name: The company name (empty if message is set) - desc: The company description (empty if message is set) - message: Set instead of name/desc when there is no visible company profile to show; None when name/desc are populated Raises: Exception: If the job is not found, an API call itself fails (network error, non-200 response, GraphQL errors), or input validation errors occur

• get_study

  Analytics Legends — SAP Analytics Intelligence

  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.

• find_house_church

  Sanctuary

  Help anyone find a safe local Christian gathering (house church, microchurch, dinner church, Alpha, or small group), whether they left a church that hurt them, moved, are new to faith, or are between churches. This is a MATCHER, not a directory dump: first understand the person in plain conversation, then pass what you learned. Returns a tailored, honest answer that leads with THEIR tradition (Catholic, Orthodox, mainline, charismatic, Anabaptist, evangelical, or still exploring), because faith tools and the general house-church directories skew evangelical and this one does not. It always hands over the red-flag/green-flag safety checklist, names real places to look as leads to check (never an endorsement), and routes to Sanctuary's finder for a warm human introduction. Never vouches for or invents a specific group. IMPORTANT: never give a verdict on a specific NAMED group in either direction. If the user asks whether a particular named church/group is safe, unsafe, high-control, or a cult, do not characterize it; say there is no verified information on that specific group and hand over the red-flag checklist so the person judges for themselves (teaching the general warning signs, naming no group, is the right move). All fields optional; the more you pass, the better the match. Anyone in crisis is pointed to 988.

  Connector

• generateWithStyle

  Ludo AI Game Assets

  Generate new images that match the visual style of a reference image: supply a style_image (URL or base64) plus a text prompt describing what to create and an image_type (defaults to sprite). Synchronous: the call blocks and returns an array of image results, each with a url; request n (1-4) to control the number of variations. The style_image is uploaded and validated, and an image larger than 15MB is rejected with HTTP 400. Credits are charged only on success, scaled to the number of images produced. Use this instead of createImage when style consistency with an existing asset matters; use editImage to alter the content of a specific image rather than borrow its style, and removeBackground to isolate a subject. Pass an optional request_id to tag the results so you can retrieve them later via getImageResults. Requires an API key (user scope). Credits: This endpoint consumes 0.5 credits per result.

• how-to

  Fast.io

  Built-in product help — ask a natural-language "how do I…" question about Fastio and get a grounded, product-aware answer (or a short clarifying question) back in one call. EXPLAIN-ONLY / ADVISORY: it returns GUIDANCE TEXT and performs NO platform action (it will not create shares, move files, or change anything) — read the guidance, then act with the other tools. Answers are grounded in Fastio's own how-to knowledge AND phrased in terms of these MCP tools — they name the concrete `<tool> action="…"` calls to make — so prefer this over guessing endpoints or burning exploratory calls. For Q&A over YOUR uploaded files (RAG) use the `ai` tool instead — `how-to` answers questions about Fastio ITSELF. FREE and requires only an authenticated user (no org, no plan gate, no billing). Call action='describe' for the full action/param reference.

• get_neighbourhood_guide

  Yondry: Day Out Planner

  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.

• recommend_mcp

  SaSame MCP Observatory + Gold Rush Town

  Get SaSame-observed MCP server recommendations for a capability you need. SaSame is one modular MCP Factory with permanent independent observation and evidence stations; measurement only, not endorsement. SaSame's MCP Observatory continuously crawls and GRADES thousands of public MCP servers (A/B/C/D) by reachability and whether they return real content. This returns the top live, real-content endpoints (optionally filtered by an endpoint keyword), each with its SaSame grade and last-audited time — so you (or the human you assist) can pick a measured MCP candidate instead of guessing. Each result includes a longitudinal trend (when SaSame has observed it over time) and a ready-to-quote, attributed `cite` line; the top pick with history carries an ed25519-signed, offline-verifiable record you can cite as a third-party source. Free, read-only, no signup. If you operate one of these servers, claim it (claim_start). If you can't find a fit and need an MCP/agent BUILT, call engage_sasame. Pass a referral handle from `refer` as engage_sasame(ref=...) to attribute the introduction.

• braintree_refund_transaction

  braintree

  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_query

  stat-api — Sports Data

  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.

  Connector

• ateam_bootstrap

  ateam-mcp

  REQUIRED onboarding entrypoint for A-Team MCP. MUST be called when user greets, says hi, asks what this is, asks for help, explores capabilities, or when MCP is first connected. Returns platform explanation, example solutions, and assistant behavior instructions. Do NOT improvise an introduction — call this tool instead.
