## AI Agent Integration (MCP & A2A)

OPN exposes PackIndex and PACKIQ through standard agent protocols. All protocols share one tool set.

### Model Context Protocol (MCP)
- Endpoint: https://opnplatform.com/api/mcp (Streamable HTTP, single POST endpoint)
- Protocol: 2026-07-28 (stateless) · legacy initialize clients: 2025-11-25, 2025-06-18, 2025-03-26, 2024-11-05
- Discovery: https://opnplatform.com/.well-known/mcp.json
- Quick start: claude mcp add packindex https://opnplatform.com/api/mcp --transport http
- Auth: public tools need none; tools marked [auth] need Authorization: Bearer <OPN API key> (https://opnplatform.com/portal)

Tools:
- search_indices: Find PackIndex codes by material, input, format or plain words ('polypropylene', 'recovered paper', 'natural gas', 'kraftliner', 'corrugated box').
- get_live_index: Today's value of one PackIndex code — commodity inputs (L0: oil, gas, power, metals, recovered fibre), raw materials (L1: PP, HDPE, pulp…), semi-finished (L2: kraftliner, films…) or finished packs (L3) — in USD (and your currency), with 1-week / 1-month / 3-month / 1-year change (each period only where that much history exists) and carbon data where scored.
- get_index_history: Price history for any PackIndex code (L0-L3), one value per date: every point for up to 3 months, weekly closes for longer spans, with the change between points.
- get_all_indices: Page through index values by layer: L0 primary inputs, L1 raw materials, L2 semi-finished (paid plans) and L3 finished packs.
- get_carbon_index: Carbon footprint: finished packs (L3) in kg CO2e per unit with grade A-D; raw materials and semi-finished (board grades, pulps, polymers, aluminium, steel, cullet) in kg CO2e per tonne, virgin and PEF CFF, optionally at your recycled content.
- packindex_query: Ask a plain-English question about packaging costs, indices or which PACKIQ agent to use.
- list_packiq_agents: Browse PACKIQ AI packaging co-workers (procurement, manufacturing, compliance, finance, sales, logistics, contracts, global markets).
- get_agent_chain: After a PACKIQ agent run, get the 2-3 most logical follow-on agents with reasons.
- get_index_forecast: 12-week forward value for any PackIndex code — inputs, raw materials, semi-finished and finished packs: current level, projection, projected change and confidence.
- get_prices: Today's values for up to 20 PackIndex codes in one call (any layer: oil, gas, resins, pulp, board, films, finished packs) with 1w/1m/3m/1y change — for watchlists and cost models.
- check_quote: Is this supplier price fair? Compares a quoted price (any currency; per t, kg, lb, unit…) with the PackIndex benchmark: difference %, verdict FAIR / HIGH / LOW, where the quote sits in the benchmark's 12-month range and, with a quantity, the overpayment.
- price_adjustment: Recalculate an index-linked contract price: base price and base date plus the indices it follows and their weights (the rest is fixed).
- compare_regions: One material across regions — e.g.
- explain_price_move: Why did a price move? Splits the change over 1w / 1m / 3m / 6m / 1y into the moves of its inputs (e.g.
- get_market_movers: Biggest risers and fallers among inputs (L0), raw materials (L1) and semi-finished (L2) over 1w / 1m / 3m / 1y, optionally within a group (e.g. 'polymer', 'fibre', 'energy').
- estimate_packaging_price: Price a corrugated RSC box (FEFCO 0201) from internal dimensions and flute (E, B, C, F or double-wall), anchored to the PackIndex RSC benchmark, with a low/mid/high band, optional order total and a next-quarter projection.
- draft_packaging_spec [auth]: Turn a plain-language packaging brief into a structured spec (format, materials, dimensions, quantity, assumptions) saved as a Design Studio project.
- cost_packaging_spec [auth]: Derive the bill of materials for a Design Studio project (or a spec object) and anchor each component to live PackIndex values.
- compare_packaging_options [auth]: Optimise a Design Studio project (or a material): right-size, lightweight and substitute options with cost and carbon savings anchored to PackIndex.
- update_project [auth]: Change a Design Studio project's order quantity, target region, contents size (boxes — enables right-sizing), name or performance floor (corrugated: ECT; folding cartons: bending stiffness in mN·m; rigid packs: top-load kgf).
- list_my_projects [auth]: The user's Design Studio packaging projects (id, name, pack type, status) and Suite runs left.
- post_rfq [auth]: Request quotes on the OPN Trade Exchange for a Design Studio project or a PackIndex material code to up to 3 suppliers. listing_ids (from find_suppliers) or, by default, the 3 best-matching listings get an RFQ — needs a verified e-mail and an Exchange plan with RFQs (Business+). company_slugs (converters from find_suppliers) ask those companies to quote; the Exchange contacts them for the buyer, anonymously.
- find_suppliers: Who can quote a material or a Design Studio project: live Trade Exchange listings (price vs PackIndex benchmark) plus matched converters from the verified supplier network, filtered by country.
- get_my_rfqs [auth]: The user's sent RFQs with how many suppliers received each and how many responded; pass rfq_id for the responses (bids and, once a supplier responds, their contact).
- search_exchange_listings: Live supplier offers on the OPN Trade Exchange, filterable by PackIndex material code and origin, each with its PackIndex benchmark (live on paid plans, 12-week delayed otherwise).
- run_packiq_agent [auth]: Run a PACKIQ agent on the caller's data (quotes, invoices, BOMs, specs).
- packiq_quote_analysis [auth]: Benchmark every line of a pasted supplier packaging quote against live PackIndex finished-pack indices: deviation from the benchmark and a verdict per line (Sharp, Competitive, High, Overpriced), with market evidence for lines more than 8% above index.
- packiq_epr_fees [auth]: Estimate annual Extended Producer Responsibility fees for a packaging portfolio across active schemes (EU member states, UK, US states, Canada, Chile, Brazil): fee band per format, total liability by market and a reformulation priority list.
- packiq_recyclability [auth]: Grade a packaging structure on the EU PPWR recyclability scale (A to F) from its substrate, layers, inks, closures and adhesives: grade, reasoning, EPR eco-modulation impact and options to reach a higher grade.

Suggested flow: search_indices → get_live_index / get_prices → get_index_history → check_quote, price_adjustment, compare_regions, explain_price_move; get_carbon_index; list_packiq_agents → run_packiq_agent → get_agent_chain.
