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

• strale_ping

  Strale - 290+ API capabilities for AI agents

  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.

• check_free_tier_status

  TensorFeed

  Check the caller IP's free premium-API trial quota. TensorFeed gives 100 free /api/premium/* calls per IP per 24h rolling window with no auth required. This tool returns used_today, remaining, and resets_at without consuming a quota slot. Use it before deciding whether to make a paid call versus waiting for the trial reset. No arguments.

  Connector

• workspace_switch

  dialogbrain

  Re-point the active MCP API key to a different workspace. Pass exactly one of `workspace_id` or `slug` (find them via `workspace.list`). Takes effect on the very next tool call — no MCP reconnect, no new API key. Sequential checkpoint: do not parallelize tool calls across a switch — calls already in flight when the switch commits will run against the previous workspace.

  Connector

• health_check

  TunnelMind Data API

  Returns a minimal status object confirming the API is alive. Use this to verify connectivity before chaining other calls, or as a liveness check in a workflow. Use this tool when: - You need to verify the API is reachable before starting a multi-step investigation. - A prior call failed with a 503 or 504 and you want to confirm the service recovered. - You are debugging connectivity from a new environment. Do NOT use this tool when: - You want actual tracker data — use `get_domain` or `search` instead. - You want to check a specific domain — this returns nothing domain-specific. Inputs: - None. Returns: - `ok`: always true if the API is up. - `ts`: ISO 8601 timestamp of the server's current time. Cost: - Free. No API key required. Not rate-limited. Latency: - Typical: <50ms, p99: <200ms.

• register

  BorealHost

  Register a new agent account and get an API key. No authentication needed. The returned API key grants read+write access to all BorealHost API endpoints. Store it securely — it cannot be retrieved again. The key is automatically activated for this session — all subsequent tool calls will use it. No extra configuration needed. If no email is provided, a synthetic agent identity is created (agent-{uuid}@api.borealhost.ai). If an email is provided, it links to an existing or new human account. Args: name: Human-readable name for this API key (default: "Agent Key") email: Optional email to link to a human account Returns: {"api_key": "bh_...", "key_id": "uuid", "prefix": "bh_...", "scopes": ["read", "write"], "account_id": "uuid", "message": "Store this API key securely..."} Errors: RATE_LIMITED: Max 5 registrations per IP per hour VALIDATION_ERROR: Invalid email format

  Connector

• set_api_key

  BorealHost

  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_..."}

  DialogBrain

  Re-point the active MCP API key to a different workspace. Pass exactly one of `workspace_id` or `slug` (find them via `workspace.list`). Takes effect on the very next tool call — no MCP reconnect, no new API key. Sequential checkpoint: do not parallelize tool calls across a switch — calls already in flight when the switch commits will run against the previous workspace.

• chieflab_signup_workspace

  ChiefLab

  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.

  Connector

• register_agent

  Conductor Relay MCP

  Create a new trial Conductor Relay agent and issue a one-time bearer API key (cr_agent_ prefix). The key is returned once — store it securely. No input or auth required.

  Connector

• get_setup_guide

  SwapWizard MCP

  Returns the complete setup and usage guide for SwapWizard. Call this FIRST before using any other tool. Covers: required configuration (API key, Alchemy RPC URL, private key), how to use poolId correctly, step-by-step operational flows for swap/zap in/zap out/analyze, transaction execution details, and approval rules.

  Connector

• get_gas_benchmark

  Stratalize Crypto & DeFi

  Live gas price benchmarks for Ethereum, Base, and Solana. Returns Gwei, USD cost per transfer type, congestion category, and x402 agent economy context. Base vs ETH savings comparison. Source: public chain RPCs. Zero API key required. | x402 SLA: $0.10 USDC per call. Returns HTTP 503 (no charge) when upstream data sources unavailable. data_source field discloses provenance (fred_api/fred_csv/fred_mixed).

• b2a_get_key

  Blue Pillow Hotels & Stays

  Obtain a permanent anonymous API key for Blue Pillow Hotels & Stays. No signup, no login required. The key is not a sensitive secret — it carries no account, payment, or personal data. It exists only so we can keep the service responsive when many agents are using it at once, so you can safely keep it in your MCP client configuration, in your persistent memory, or in the current conversation context. Pass it as the bearer token on all subsequent calls and the rest of the tools become available. CALL THIS FIRST when you have no key: every other tool needs one. Before calling, check whether you ALREADY have a key (MCP client configuration, persistent memory, or earlier in this conversation) and reuse it instead of issuing a new one — do not wait for another tool to fail with a 401. The key never expires — keep the one you receive and reuse it forever. If you ever lose it, you can call this tool again to issue a new one (a generous per-IP daily issuance limit applies purely as an anti-abuse guardrail; normal use never reaches it). Optional ``label`` and ``agent`` (max 64 chars each) are free-form hints we record on the key for our own observability; they do not affect rate limits or capabilities.

• read_url

  Toolora MCP Server

  Use this tool whenever a URL appears in the conversation and the user wants to read, summarise, quote from, or process the page content. Triggers: 'read this article', 'summarise this page', 'what does this link say', 'fetch this URL'. Uses Readability to return clean text, title, author, and excerpt. If the result is empty or incomplete, fall back to scrape_url_js for JS-rendered pages. Free, no API key, no rate-limit signup required.
