• Whether its tools do the product's job has not been judged yet.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• describe_supplyslate

  Explain what SupplySlate does, what it does not do, and when a buyer-owned agent should use it.

• list_sourcing_categories

  List the editable supply categories currently accepting requests. Agents may still submit a precise request outside this list.

• get_connection_guide

  Return the exact MCP and REST connection details a buyer, developer, or agent operator needs to connect to SupplySlate.

• list_fabrication_processes

  List configurable fabrication, kitting, assembly, and test processes with their required artifacts and requirement schemas.

• get_live_fabrication_capabilities

  Read attributed live fabrication capabilities from the connected AFN provider. This is discovery only and neither uploads a design nor requests a quote.

• search_live_components

  Search attributed current electronic-component product, availability, lead-time, and price data from Mouser. Results retain provider, observation time, and merchant URLs; no checkout or order is created.

• get_requirement_schema

  Read the evidence-safe input schema for a configurable supply category or fabrication process, including required fields, recommended fields, accepted artifacts, and safety notes.

• search_products

  Search published canonical product facts. Commercial price, stock, compatibility, and lead time are returned only when separately supported by current evidence.

• get_product

  Read one published canonical product with variants, category links, evidence scope, observation dates, and freshness.

• get_compatibility

  Read one published compatibility or substitution assertion with exact subject, object, conditions, confidence, evidence source, and observation time.

• list_supplier_taxonomy

  List the product categories used by the public industrial compressor service-parts supplier directory, including verified supplier counts.

• search_suppliers

  Search source-backed public supplier profiles by product category, brand, company type, service, compressor type, industry, or text. No authentication required.

• get_supplier

  Read one public supplier profile with source URLs and evidence for every category, capability, and brand claim.

• create_project

  Create a durable supply project from an idea, file, BOM, exact part, or RFQ origin. Requires a scoped buyer credential.

• get_project

  Read a project, its current immutable-capable revision, requirements, artifacts, BOM summaries, and validation history.

• update_project_requirements

  Replace the structured requirement set on an unlocked project revision. Confirmed flags distinguish buyer-confirmed facts from agent interpretation.

• create_artifact_upload

  Create a short-lived, one-time private artifact upload URL. The caller must stream the exact declared bytes with a SHA-256 checksum.

• attach_artifact_reference

  Attach an HTTPS repository, document, drawing, datasheet, BOM, or design reference to the current project revision without copying its bytes. Private or expiring URLs remain the buyer's responsibility until uploaded directly.

• upsert_bom

  Create a BOM or a new BOM revision with assemblies, catalog items, custom parts, services, consumables, artifacts, and interface dependencies.

• get_bom

  Read the current revision of one project BOM, including hierarchy, quantities, sourcing state, and interface dependencies.

• validate_project

  Run the current versioned validators and return separate blocking errors, compatibility conflicts, warnings, missing information, passed checks, and unavailable checks.

• list_project_validations

  List versioned validation reports for a project without implying licensed engineering approval.

• source_project

  Lock the validated project revision into an immutable sourcing package, create normalized request lines, and return transparent supplier candidates. This does not contact suppliers; a human operator must approve every outbound recipient…

• create_purchase_plan

  Create an immutable, single-currency, multi-supplier purchase plan from selected current quote lines, choosing at most one commercial option per requested line. This records a plan only; it neither approves nor purchases anything.

• get_purchase_plan

  Read one exact purchase-plan version with selected lines, merchants, totals, risks, evidence, approvals, and checkout handoffs.

• request_purchase_approval

  Create a human review link bound to the exact purchase-plan version, suppliers, maximum amount, currency, risks, and expiry. This does not approve or purchase the plan.

• get_checkout_handoffs

  List merchant-hosted checkout, supplier invoice, or merchant-order handoffs for an approved plan. Suppliers remain merchant of record and SupplySlate does not process funds.

• create_provider_checkout_handoff

  After a human has approved the exact purchase plan, create one supplier-hosted payment link for a checkout-connected provider offer. This creates an unpaid provider order but never submits payment or exposes payment credentials to…

• list_orders

  List merchant-confirmed orders for the buyer organization. A plan or queued handoff is never represented as an order.

• get_order

  Read one merchant-confirmed order with items, fulfillment, shipments, issues, evidence, and event history.

• report_order_issue

  Open a durable post-purchase issue for a merchant-confirmed order. This notifies the supplier-side organization and records owner, status, and event history; it does not claim a resolution.

• request_order_cancellation

  Ask the merchant to cancel an unshipped order. This creates a request and notification; it never reports the order as cancelled until the supplier or an operator accepts it.

• request_order_return

  Open a return request after shipment. The supplier remains merchant of record and controls authorization and refund state.

• open_warranty_claim

  Open a durable warranty claim on an accepted order or specific order line. This records the claim and notifies the supplier without asserting eligibility or approval.

• update_supplier_capabilities

  Replace the supplier-submitted capability set while preserving separately sourced public, operator-verified, and transaction-proven evidence.

• update_availability

  Append timestamped supplier availability evidence and update current catalog state by supplier SKU without rewriting historical snapshots.

• list_supplier_rfqs

  List approved RFQs matched to the authenticated supplier. Requires a supplier API key.

• get_supplier_rfq

  Read an approved RFQ and its normalized buyer line items. Requires a supplier API key.
