"Automatic Data Visualization Tool (No API Key Required)" matching MCP tools:

• set_api_keyA

  BorealHostA

  Set your BorealHost API key for this session. Call this if you already have an API key (from a previous registration, checkout completion, or the BorealHost panel). All subsequent tool calls will use this key for authentication. No need to call this after register() — the key is set automatically. Args: api_key: Your BorealHost API key (format: bh_<48 hex chars>) Returns: {"success": true, "message": "API key set for this session", "key_prefix": "bh_..."}

  ConnectorNo auth

• register_agentA

  PromptDNAB

  Step 1 of autonomous self-registration - no API key required. Costs $0.01 USDC on Base (anti-spam fee, not a wallet-ownership proof). Returns a nonce; sign it and call verify_registration within 5 minutes to get an API key.

• factreason_create_keyA

  FactGrid (Renamed to FactReason)A

  Get a FactReason API key for yourself, instantly, with no human, no signup and no card. Returns a key carrying one-off trial credit that you can spend immediately on any tool. CALL THIS FIRST if you have no key, or as soon as any FactReason tool returns HTTP 402 Payment Required — then retry the original call with the key. The tool is free and is never metered. Supplying an email is optional and only affects whether trial credit is granted; a key is always issued either way.

• cogdepot_get_startedA

  cogDepotA

  Explains, in order, how to obtain a cogDepot API key and become able to trade. Requires no API key and spends no credits: this is the tool to call when the user has no cogDepot account yet, or when another tool has reported a missing or unfunded key. Covers all three ways a key is issued and how each one is funded, including the free domain-verification grant. Returns instructions for a human or agent to follow. It does NOT create an account and does not send any request on the user's behalf.

• search_gmailA

  Dayze — Life in Days + Notable PeopleB

  Search the authenticated user's already-connected Gmail inbox (read-only). Reuses the Dayze Integrations hub Gmail connection (service_connections provider=gmail, scope gmail.readonly) — no new OAuth vendor. Prefer Gmail operators: from:, subject:, is:unread, newer_than:7d, has:attachment. Returns id, subject, from, date, snippet only (no body). Follow up with read_gmail_message for the full body. Cannot send, archive, or delete. Never invent email contents. If Gmail is not connected, connect at /integrations. Requires API key or OAuth with scope context. Share tokens cannot call this tool. ($0.10; API key required)

• server_infoA

  HackMyIP — no-key IP intelligenceA

  Describe this MCP server: what it wraps, the fact that it is completely free with no API key, no signup and no auth, the fair-use rate limit, the full tool list, and links to hackmyip.com and its API docs. Call this when the user asks what this server can do, whether it costs anything, or where the data comes from.

• mint_keyA

  Agent BrokerA

  Agent self-serve API key issuance. An autonomous agent that has no email inbox can obtain a free-tier API key by proving it holds the MACHINE_MINT_SECRET via HMAC-SHA256. Returns a usable key immediately with no human action required. If the operator has not activated a mint secret on the server, this returns an honest not_configured failure rather than a key - call it once and branch on that before planning around it. EXAMPLE USER QUERIES THAT MATCH THIS TOOL: user: "I need an API key to call AgentBroker tools" -> call mint_key({"agent_id": "my-agent-abc123", "timestamp": 1725100000, "nonce": "4f8a2c1d", "signature": "<HMAC-SHA256(agent_id+timestamp+nonce, MACHINE_MINT_SECRET)>"}) WHEN TO USE: Use when an AI agent needs to self-provision a write-capable API key without a human email address. The caller must know the MACHINE_MINT_SECRET (available from hatchloop.dev/docs/#machine-mint). WHEN NOT TO USE: Do not use if the agent has a human operator who can complete the email flow at /keys/request. Do not use for paid plans — this endpoint issues free-tier keys (100 ops/day) only. COST: free - no key required LATENCY: ~100ms

• cc.liquidation_heatmapA

  Central Command — x402 Trading IntelligenceA

  Call cc.liquidation_heatmap — Liquidation cluster visualization data showing where leveraged positions would be force-closed at each price level. Purpose: Liquidation cluster visualization data showing where leveraged positions would be force-closed at each price level. Behavior: READ-ONLY. Does not place orders, move funds, or mutate your exchange account. Responses may be cached (~1800s). Auth: X-Api-Key or x402 payment proof (X-PAYMENT / __x_payment). Anonymous unauthenticated calls receive HTTP 402 with payment accepts. Cost: $0.005 USDC per successful call (x402 Base USDC pay-per-use or prepaid X-Api-Key balance). Linked Connect keys are free. This is billing, not a side effect. Rate limit: 20/min (per API key). Tier: premium. Returns: 3D matrix: price levels x leverage tiers x liquidation volume. Identifies magnetic price targets. Guidelines: Use for research / signal context. Pair with cc.agent_strategy (paper) before any live order. Do not invent fills from this data alone. Tags: liquidations, heatmap, leverage, magnetic-levels, risk.

• strale_pingA

  Strale - 290+ API capabilities for AI agentsA

  Checks that the Strale API is reachable and the MCP server is running. Call this before a series of capability executions to verify connectivity, or when troubleshooting connection issues. Returns server status, version, tool count, capability count, solution count, and a timestamp. No API key required.

  ConnectorNo auth

• fabric_create_identityA

  Fabric MarketplaceA

  Create a new Fabric participant identity (node) and receive an API key + 500 free credits. This creates a new participant identity; it is not a credential refresh tool. Do not use this if the participant already has a node. Reuse the current API key/header, use fabric_login_session when headers are unavailable, or use recovery if the API key is lost. No authentication required. Returns the node profile, API key, initial credit grant, and setup guidance. After creation, immediately persist node.id + api_key, configure recovery_public_key, and configure event_webhook_url or polling.

• list_applicationsA

  FlowCastleA

  List the applications this API key can access, with the caller role and the permissions it grants. Start here when using a personal API key (usr_...): every other tool needs an explicit applicationId, which this tool supplies. Read-only, takes no arguments. Returns an array of { id, name, role, permissions }; an empty array means the key is valid but belongs to no application yet.

• oruk_get_startedA

  oruk SpeechA

  Quickstart for the oruk Speech API and this MCP server: how to get an API key, per-client MCP configuration snippets, SDK install commands, and an optional routing rule the user can add to their agent instructions. No API key required. Use this when setting oruk up for the first time or when the user asks how oruk works.

• list_api_keysA

  MisarMail MCP ServerA

  List the API keys on the account with their scopes and when each was last used. Use it to audit access — to spot keys that are unused, over-scoped, or forgotten. It lists key METADATA only: the secret values are not returned by this or any other tool, so a key that has been lost must be rotated rather than recovered. Reads only; no key is created, revoked, or rotated. Requires an API key. Scope and last-used data is security-relevant, so treat the listing as sensitive even though it contains no secrets.

• wallet_activityA

  x402 BazaarA

  Recent transactions for an address — The latest transactions for a Base address — hash, time, from/to, ETH value, success — via Covalent. For agents tracking what a wallet is doing. Required input: address. Priced $0.03 per call over x402 on Base; send a prepaid x-credit-token header for unlimited calls, or get 1 free call/day per tool. No wallet or API key required.

• chieflab_signup_workspaceA

  ChiefLabA

  USE WHEN the user has no ChiefLab API key yet and you've gotten a 401 / 'authentication required' error from any other tool. Agent-first signup: creates a new workspace and returns the API key inline as `apiKey`. PREFERRED flow: use your filesystem tools to write the apiKey into the user's MCP config (see mcpConfigSnippet for the patch shape), then ask the user to restart their runtime once. After restart, re-call the original tool. FALLBACK: if you can't write to the config file, surface the included deliveryUrl to the user — they click, see the key, paste it manually. URL expires in 1 hour, single-use, IP-rate-limited (5/IP/hr). No login form.
