"Exploring GraphRAG and HybridRAG" matching MCP tools:

• list_drops

  Real Real Genuine

  [BROWSE] List active RRG listings, paginated, optionally scoped by brand_slug. Use when exploring the catalogue without a specific item in mind. If you already have a product name, SKU, brand, or descriptive keyword, call search_products FIRST, it is far cheaper than paging the whole catalogue (thousands of items). Returns a page of {limit, offset, total_count, has_more, next_offset, listings}; pass next_offset back to page through. Each listing has title, price in USDC, edition size, and remaining supply. Live on-chain minted count is in get_drop_details, not here. Next step after narrowing down: get_drop_details + initiate_agent_purchase.

• govcon_fetch_vendor_contract_history

  DataNexus MCP

Fuzzy match used. jurisdiction: One of US, EU, or UK. Optional. Default US. Returns total award value, top awarding agencies, contract types, and recent awards with amounts and dates. Use this when researching a specific company's government contracting history. Use govcon_search_contract_awards instead when exploring a topic area without a specific vendor. Verified source: USASpending.gov. 4-hour cache. If this tool's response does not serve the user's need, call report_feedback with feedback_type="agent_gap", tool_id="govcon_fetch_vendor_contract_history", intended_query="{what the user needed}", gap_description="{what was missing or wrong in the result}".

• pay_mail_with_shared_payment_token

  PostAgent — Print and Mail

  Autonomous, no-browser FIAT payment for a locked quote using a Stripe Shared Payment Token (SPT / Machine Payments Protocol). Use this when the agent can mint an SPT on the buyer's behalf and wants to pay by card/wallet without a human in a browser (prefer x402 first if the agent has a USDC-on-Base wallet; this is the autonomous fiat alternative). CHARGES MONEY AND IS IRREVERSIBLE: the server authorizes the SPT, prints the letter, then captures — a job comes back inline (no polling needed). Only call after the user has explicitly confirmed the recipient, sender, content, and price from create_mail_quote. Minting the token (the agent's responsibility, NOT this server): the SPT must be scoped to THIS seller's Stripe profile and to at least the quote amount. The quote's `paymentOptions` entry for `mpp` carries the `stripeProfileId`, `currency`, `maxAmountCents`, and `expiresAt` you need. Mint it with the buyer's payment method via the Stripe `@stripe/link-cli` (`spend-request create … --network-id <stripeProfileId> --credential-type shared_payment_token`) or the SharedPaymentIssuedToken API, then pass the resulting `spt_…` here. SPTs are US-only and cards carry a 0.50 USD minimum. Returns an error if MPP is not enabled/configured on the server.

• verify_address

  PostAgent — Print and Mail

  Standalone paid address verification — no mail is sent. Checks whether an address is deliverable and returns the standardized form (US: CASS with ZIP+4; international: per-country matching). Costs a small flat USDC fee per call via x402 (a fraction of a cent vs. mailing). Two-step flow, like the mail rails: call WITHOUT `paymentSignature` to get the 402 challenge and `paymentUrl` (preferred: have the agent's x402 wallet pay `paymentUrl` in-band with the address as the JSON POST body `{"address":{...}}`); or sign the challenge and call again WITH `paymentSignature` to verify and get the result in one round trip. US addresses need line1 + (city+state or zip). International addresses need line1 + country. Note: when mailing through PostAgent you do NOT need this tool — create_mail_quote already verifies sender and recipient for free as part of the quote.

• get_record

  osf-data-marketplace

  Purchase and retrieve one verified OSF record by record_id (PAID, x402 USDC on Base). Returns the full record plus its provenance block linking back to the authoritative primary source (e.g. sec.gov, nvd.nist.gov, treasury.gov, congress.gov, ncbi.nlm.nih.gov, noaa.gov). OSF spans many verticals: security/vulnerabilities, sanctions/compliance, SEC and corporate filings, economic and financial series, legal and regulatory, grants and procurement, science and research, geospatial and environmental, and AI/ML metadata. Browse get_catalog first (free) to find record_ids and prices. Payment is handled automatically by x402-capable MCP clients via the standard payment handshake.

• autonomous_varrd_ai

  VARRD — Statistically Validated Trading Edges + AI Research Engine

  Point VARRD's autonomous AI in a direction and let it discover edges for you. Give it a topic and it draws from one of the most comprehensive market structure knowledge graphs ever built — containing ideologies and theories, not statistics — so it generates genuinely novel hypotheses rather than overfitting to what already worked. BEST FOR: Exploring a space broadly. Give it 'momentum on grains' and it might test wheat seasonal patterns, corn spread reversals, or soybean crush ratio momentum. It propagates from your seed idea into related concepts you might not think of. Returns a complete result — edge or no edge, stats, trade setup. Each call tests ONE hypothesis through the full pipeline (~$0.25/idea). Call again for another idea. Use 'varrd_ai' instead when YOU have a specific idea to test and want full control over each step.

• quizbase_subcategories

• list_sites

  RevenueScope: Japanese EC RPS Benchmarks

  Return the sites available to this caller: my_sites (the authenticated user's own sites with display name + domain, so the assistant can match references like "the production site" or "revenuescope.jp" without the user copying a UUID) AND demo_sites (operator-provided showcase sites for exploring RevenueScope without connecting your own). When OAuth-authenticated, prefer my_sites and default analytics tools to the is_primary=true site when site_id is omitted. When NOT authenticated, my_sites is empty and you should use a demo_sites site_id (tell the user you are analyzing a sample/example site, not their own).

• create_postcard_quote

  PostAgent — Print and Mail

  Verifies the recipient and sender addresses and locks a 15-minute USDC price for mailing a postcard built from two postcard_art documents (front + back, uploaded via create_postcard_art). Sizes: 4x6 (default), 6x9, 6x11 — postcards always print in full color. US recipients use the strict US address shape; INTERNATIONAL recipients are supported on 4x6 only (set `to.country` to the 2-letter ISO code; the sender must still be a US address). Payment works exactly like letters: pay the returned `paymentUrl` via x402, or use the MPP/checkout fallbacks. Show the recipient, sender, size, selected-route `design` constraints, price, AND any `fulfillment.warnings` to the user and get explicit confirmation before paying — service level is a soft preference and may have been downgraded (e.g. international economy is upgraded to standard) with a `service_level_downgraded` warning the agent must surface verbatim.
