• tronsave_internal_create_extend_request

  TronSave MCP Server

  Submit an extension request for existing delegated resources on TronSave, paid from the internal account. Requires a logged-in MCP session created by the `tronsave_login` tool: include `mcp-session-id: <sessionId>` returned by `tronsave_login` on subsequent MCP requests. Internal tools never accept API keys via tool arguments; signature sessions resolve the latest internal API key on demand, while api-key sessions reuse the validated key from login. Side effect: SPENDS internal TRX and creates an extension order; not idempotent. Use as STEP 2 after `tronsave_internal_extend_delegates` — pass its `extendData` rows unchanged. Returns `{ orderId }` for the new extension order.

• adcritter_build_app

  AdCritter for Builders

  Start here when building an application. Returns an overview of what the AdCritter platform offers and a catalog of feature guides you can query with the adcritter_guidance tool to learn how to build each part of the app. Call adcritter_guidance(key) for any feature area to get detailed building instructions with API endpoints and response shapes.

• resize_database_storage

  Dockhold

  Grow the disk of an app's managed database. Call this when the database is running out of disk space. GROW-ONLY: you can increase storage but never shrink it. storage_gb must be one of the sizes get_resource_usage reports under storage.steps_gb and fit your storage pool. Applied online with no database restart. Only works if the app has a managed database.

• koreanpulse_about

  koreanpulse

  Server self-description — capability matrix, tool catalog, named-entity tag counts, supported query patterns, primary sources. Free tier. Use this tool when an agent first connects and needs the capability matrix to decide whether this server can answer the user's question, or when the user asks "what can koreanpulse do" or "what data sources does this MCP server provide". Returns a structured dict that downstream agents can ingest directly.

• get_sample_creator

  Influship

  Use this when a ChatGPT user wants to see what Influship can return before linking an account. Fetches one configured sample creator with social profile context. This is a low-cost preview tool and should not be used for search, discovery, matching, or lookalike requests. After showing the preview, tell the user that real live creator data, search, lookalikes, matching, posts, and transcripts require connecting an Influship account. Explain that they can authorize either an Influship SaaS subscription, where usage counts against monthly bundled credits, or an Influship API account, where usage is billed pay-as-you-go under API billing.

• list_repos

  canton-ccpedia

  List the Canton Network GitHub repositories that CCPEDIA has indexed (Canton org repos — e.g. canton-foundation, Daml/Splice — excluding the dev-fund proposals repo), with the count of issues+PRs indexed per repo. CANTON-ONLY and read from CCPEDIA's cache — this is NOT a live GitHub API and does NOT list the user's own repos (use a GitHub MCP for that).

  Connector

• list_displays

  agentView

  Lists all displays the user can access, with id, name, online status, lock state and device class — the starting point to discover display IDs before get_display, send_html or send_store_template_to_display. Pass org_id to list an organization's displays instead. response_format 'detailed' adds screen/viewport facts, URLs and language per display. To show what a display looks like right now, use get_display_preview_url. Requires content scope.

  Connector

• search_mcp_servers

  agent-tools (x402 + MCP + A2A directory)

  Find MCP servers in the directory. Searches the standalone MCP directory (PulseMCP / official MCP registry import) unioned with x402 services that also expose an MCP endpoint. Returns normalised entries with a ready-to-use streamable-http `call_hint.mcp.url`. Args: intent: Natural-language description of the tool/capability needed. top_k: Max servers to return (1-20). chain: Optional payment-network filter for paid MCP servers. require_healthy: When true, only return servers marked health=ok.

  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.

• quick_check

  mcp-judge

  FREE, no payment required. Instant trust check of any MCP server: returns only the 0-100 score, A-F grade, tool count, latency and a one-line verdict — no detailed report. Use this FIRST, before integrating any third-party MCP server, to see at a glance whether it is technically trustworthy; an unreliable MCP wastes your tokens and can break your workflow. For the full actionable report (per-tool documentation coverage, functional probe results, score breakdown, plain-language summary) call evaluate_mcp; to pick between alternatives call compare_mcps. Set 'url' (required) to the target's MCP endpoint (Streamable HTTP), e.g. https://host/mcp.

• ic_capabilities

  Immersive Commons

  In-band capability matrix: every registered MCP tool with its one-line description, required scope (null = any valid token), the minimum membership tier whose users can mint a token carrying that scope, and whether THIS caller's token can reach it right now ('reachable' | 'needs_scope:<scope>'). Use it to plan before calling scope-gated tools and to tell your human exactly which tier + scopes a token needs — remember scopes CANNOT be added to an existing token (a new one must be minted with the scope in the signup array). Available to any valid token — no extra scope. Args: none. Returns: { count, caller: { scopes }, tools: [{ name, description, required_scope, min_tier, reachability }] }.

• snapforge_signup

  SnapForge

  Create a free SnapForge account (100 renders/month) with just an email address and get the API key instantly. The key is bound to the current MCP session, so the screenshot/pdf/markdown tools work immediately after signup — no browser needed.

• ping

  FXMacroData

  Quick health check that confirms the FXMacroData API and MCP server are reachable. Use this only if other tools fail unexpectedly — it is not needed before normal calls.

  Connector

• tronsave_get_internal_account

  mcp

  Retrieve the TronSave internal account profile for the current session: represent address, deposit address, and balance (SUN). Requires a logged-in MCP session created by the `tronsave_login` tool: include `mcp-session-id: <sessionId>` returned by `tronsave_login` on subsequent MCP requests. Internal tools never accept API keys via tool arguments; signature sessions resolve the latest internal API key on demand, while api-key sessions reuse the validated key from login. Use when the user needs their linked address, deposit address, or internal balance. This is the api-key internal account, not the on-chain wallet. Read-only; does not submit orders or change chain state. FRESHNESS: balance reflects live state and can change within seconds after deposits/orders.

• tronsave_internal_order_book

  mcp

  Return the current TronSave market depth/price tiers for ENERGY or BANDWIDTH via the api-key REST endpoint. Requires a logged-in MCP session created by the `tronsave_login` tool: include `mcp-session-id: <sessionId>` returned by `tronsave_login` on subsequent MCP requests. Internal tools never accept API keys via tool arguments; signature sessions resolve the latest internal API key on demand, while api-key sessions reuse the validated key from login. Use before `tronsave_internal_order_create` or `tronsave_internal_order_estimate` when the user needs live prices or liquidity. Read-only. FRESHNESS: live market depth can change roughly every 3 seconds (one TRON block) — re-read immediately before placing an order.

  Connector

• tronsave_internal_order_estimate

  mcp

Requires a logged-in MCP session created by the `tronsave_login` tool: include `mcp-session-id: <sessionId>` returned by `tronsave_login` on subsequent MCP requests. Internal tools never accept API keys via tool arguments; signature sessions resolve the latest internal API key on demand, while api-key sessions reuse the validated key from login. Use when the user wants a quote or price check; feed the result into `tronsave_internal_order_create`. Read-only. FRESHNESS: `unitPrice`/`estimateTrx` are live and can change roughly every 3 seconds — re-estimate immediately before creating the order.
