"Search functionality without API key requirement" matching MCP tools:

• get_variable_relationshipsA

  hypathesisA

  Retrieve analyzed variable relationships for a completed paper. Only returns results when get_analysis_status reports status='Ready'. Without an API key (anonymous): returns the relationship list with source, target, and direction — but detailed reasoning is available only with an API key. Sign up at https://hypathesis.com to get one. Args: file_id: The file_id returned by the /upload endpoint. authorization: Optional. API key as 'Bearer hk_...' or 'hk_...'. session_token: Optional. The session_token returned by /upload for anonymous uploads. Returns: Authenticated: full details (source, target, directed, reason per relationship; name, measure per variable). Anonymous: gated (source, target, directed per relationship; name per variable; sign_up_url for full access).

• admin_create_newsA

  mcpA

  Admin-only: publish a news article directly into any locale, any status, with no safety classifier and no English-first requirement. Requires an api_key belonging to an admin account — a valid but non-admin key is rejected. For non-admin accounts, use draft_news instead. Can also queue selected translations or every missing locale without keeping the MCP request open while translation runs.

• request_api_keyA

  Nefesh — Real-Time Human State Awareness for AIA

  Request a free Nefesh API key. No existing API key needed for this call. IMPORTANT: You MUST ask the user for their real email address before calling this tool. Do NOT invent, guess, or generate an email address. The user will receive a verification link they must click to activate the key. Without clicking that link, no API key will be issued. Disposable or temporary email services are blocked. Example prompt to the user: "What is your email address? You will receive a verification link to activate your free API key." Flow: call this with the user's real email, then poll check_api_key_status every 10 seconds until status is 'ready'. Free tier: 1,000 calls/month, all signal types, 10 req/min. No credit card.

• get_direct_crawl_paymentA

  Xcatcher — Recent X PostsA

  Create a request-bound x402 v2 payment requirement for an accountless crawl. Use this only for the accountless x402 path after preflight_crawl; API-key accounts use create_crawl_task instead. Normal requests use progressive batch pricing, so quote the complete deduplicated handle list together. This does not move funds. Return payment_required_b64 unchanged to an x402-compatible wallet/client; the live amount, asset, network, destination, and quoteId are authoritative.

• search_my_collectionA

  MTG BenchA

  Search only the cards the user OWNS, by name, colors, or type. Set notInDecks to surface owned cards not currently used in any of their decks (the "what is sitting idle in my binder" question). Use search_cards instead to search every Magic card regardless of ownership. Returns at most 100 owned cards per call, with the full match count in `total`. Requires a free API key (send it as "X-API-Key: <key>" or "Authorization: Bearer <key>").

  ConnectorNo auth

• create_uploadA

  SingleFaxA

  Optional. Prefer create_fax_draft with base64. Pass base64 here to store the file on this authenticated call (no PUT). Without base64, returns a PUT URL for API-key clients.

  ConnectorOAuth

• get_quotaA

  TollCalc MCPA

  Check remaining free-tier quota for this MCP session. Without authentication, 10 free requests are available per session. Pass an API key via Authorization: Bearer <token> header for plan-based quota.

  ConnectorNo auth

• get-code-iq-automated-queriesA

  coderegistryA

  Returns trimmed Code IQ automated analyses (architecture, scalability, EOL, AI functionality, etc.) for a project (aggregated) or a single vault. Excludes The Code Score — use get-the-code-score for that, and do not pass analysis_key=code_score here (404). Only cached results are returned; this never triggers a fresh analysis. Provide exactly one of project_id or vault_id. Requires full data access (a paid plan; verification-only plans are not included). Requires X-API-Key (existing users can generate an API key in the web app). If headers aren't supported, pass api_key in arguments.

  ConnectorNo auth

• analyze_geoA

  Lotus — AI Citation IntelligenceA

  Analyze a domain's visibility across AI-generated answers. Without an API key: returns a limited preview (1/day per IP, 3/week). With a valid API key: returns the full analysis including measured metrics, revenue-at-risk estimates and scenario simulations.

  ConnectorNo auth

• get_memoriesA

  Dayze — Life in Days + Notable PeopleB

  Authenticated user memories from Dayze Agent. Pass query for semantic/keyword retrieval. Prefer search for event-first trip and calendar titles. Requires OAuth or a supported scoped credential. ($0.10; API key required)

  ConnectorNo auth

• ateam_authA

  ateam-mcpA

  Authenticate with A-Team. Required before any tenant-aware operation (reading solutions, deploying, testing, etc.). The user can get their API key at https://mcp.ateam-ai.com/get-api-key. Only global endpoints (spec, examples, validate) work without auth. IMPORTANT: Even if environment variables (ADAS_API_KEY) are configured, you MUST call ateam_auth explicitly — env vars alone are not sufficient. For cross-tenant admin operations, use master_key instead of api_key.

  ConnectorNo auth

• revoke_api_keyA

  DockA

  Revoke an API key (soft-delete via `revokedAt`). Subsequent requests with the key return 401. Agents may revoke ONLY their own key; calling this is effectively a self-destruct, the response itself completes but the very next request will fail. Users may revoke any key they own. To swap creds without going dark in the gap, use `rotate_api_key` instead.

  ConnectorNo auth

• chieflab_connect_providerA

  ChiefLabA

  Connect a third-party provider (Zernio, Resend, GA4, Search Console, HubSpot, Stripe, Linear, Notion, Slack) to this workspace. USE WHEN the user wants to wire up publishing, email sending, or analytics readback. For OAuth providers (ga4 / search_console / hubspot) returns an authorizeUrl the agent surfaces to the user. For API-key providers (zernio / resend) returns instructions for the set-key tool. Without this, publish/send/measure tools return 'configure first' errors.

  ConnectorNo auth

• try_demoA

  MCPSpendA

  Run this WITHOUT an API key to see what MCPSpend output looks like. Returns a synthetic cost snapshot identical in shape to get_today_cost + list_top_tools + get_usage_this_month. Use this to preview the product before signing up.

  ConnectorNo auth

• zerodust_register_api_keyA

  zerodustA

  Issue this agent its own ZeroDust API key for higher rate limits, with no human signup step. The other tools work without a key, so only call this when rate limits are being hit, or when setting up an unattended agent that will run repeatedly. The key is returned once and cannot be retrieved later - report it to the operator.

  ConnectorNo auth

• get_demo_compositeA

  Compound Interesting — market intelligenceA

  A single fixed demo ticker, callable without an API key, so the data shape can be inspected before signing up. Returns only the demo ticker regardless of input. For real tickers use get_composite, which requires a free key.

  ConnectorNo auth

• api_indexA

  ExMachina AI — agent research roomsA

  Every HTTP endpoint with its auth requirement, body shape and worked examples, plus the reputation weights and citation semantics as data. Use this when you want to call the HTTP API directly instead of through MCP.

  ConnectorNo auth

• opcua_model_validateA

  OPC UA ModelerA

  Validate an OPC UA YAML model for correctness. Returns diagnostics with severity (error/warning/info), codes, messages, and line numbers. Works without an API key (limited to 50 calls/day). ALWAYS validate before generating.

  ConnectorNo auth

• generate_testsA

  SpecProofA

  Generate a cited, runnable conformance test that verifies one normative requirement. The test is grounded in the requirement sentence plus its surrounding clause from the corpus, and every test cites the spec, section and page it enforces. If the requirement is not testable (boilerplate, scope text), the generator abstains rather than inventing a test. Args: requirement_id: The requirement's id, as shown by get_requirements target: "pytest" for a runnable Python test module, or "gherkin" for a reviewable .feature file (default: pytest)

  ConnectorNo auth

• database_search_replaceA

  BorealHostA

  Search and replace in WordPress database (e.g. URL migration). Handles serialized data safely. Use dry_run=true first to preview changes. Requires: API key with write scope. Args: slug: Site identifier old: String to search for (e.g. "http://old-domain.com") new: Replacement string (e.g. "https://new-domain.com") dry_run: Preview only without making changes (default: true) Returns: {"replacements": 42, "tables_affected": 5, "dry_run": true}
