Available tools 55

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

supplier

get_supplier

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

get_supplier_offers

Retrieve current normalized supplier quote revisions for one buyer sourcing request, including unquoted lines, compatibility, price, availability, lead time, terms, and evidence. SupplySlate returns explicit tradeoffs and applies no hidden winner score.

get_supplier_profile

Read the authenticated supplier's SupplySlate profile and current catalog-item count. Requires a supplier API key.

get_supplier_rfq

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

list_supplier_orders

List merchant-confirmed orders attributable to the authenticated supplier. RFQs, quotes, plans, and checkout handoffs are not represented as orders.

list_supplier_rfqs

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

list_supplier_taxonomy

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

update_supplier_capabilities

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

update_supplier_order

Acknowledge or update fulfillment on a merchant-confirmed supplier order, optionally recording a shipment. State transitions and order-item quantities are validated and audited.

update_supplier_order_issue

Update ownership, status, or resolution for a buyer-reported issue on the authenticated supplier's merchant order.

update_supplier_order_return

Advance an authenticated supplier return through authorization, shipment, receipt, and refund states without changing historical order evidence.

update_supplier_warranty_claim

Advance a warranty claim through supplier review, approval, replacement, resolution, or rejection with a merchant reference and durable history.

project

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.

list_project_validations

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

update_project_requirements

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

request

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.

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.

sourcing

get_sourcing_request

Read the current status and normalized line items for one authenticated buyer sourcing request.

list_sourcing_categories

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

list_sourcing_requests

List recent sourcing requests owned by the authenticated buyer organization across API keys and OAuth agents.

live

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.

purchase

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.

submit

submit_sourcing_request

Submit a real non-sensitive B2B sourcing request on behalf of the buyer. SupplySlate routes it to relevant suppliers and returns structured offers later. Requires a buyer API key.

submit_supplier_quote

Submit the first structured commercial quote for a human-approved RFQ. Money is integer minor units with an explicit currency; partial line coverage and labeled alternatives are allowed.

upsert

upsert_bom

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

upsert_supplier_catalog

Create or update normalized supplier catalog items through a durable manual import with row-level validation, history, evidence scope, availability, and commercial terms.

artifact

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.

ask

ask_rfq_clarification

Ask the buyer a clarification question on an approved supplier RFQ without changing the immutable request package.

attach

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.

availability

update_availability

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

bom

get_bom

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

catalog

create_catalog_import

Create a durable CSV, XLSX, JSON, feed, API, document, or manual catalog import. Supply parsed rows for immediate validation, or an artifact/source reference to enter the mapping workflow.

checkout

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.

compatibility

get_compatibility

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

connection

get_connection_guide

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

decide

decide_supplier_order_cancellation

Accept or reject a buyer cancellation request for the authenticated supplier's unshipped merchant order. Acceptance is the state-changing merchant decision.

decline

decline_supplier_rfq

Decline an approved RFQ with a structured reason so the buyer and network can route more accurately.

describe

describe_supplyslate

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

fabrication

list_fabrication_processes

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

open

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.

order

get_order

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

orders

list_orders

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

product

get_product

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

products

search_products

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

provider

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 SupplySlate.

report

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.

requirement

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.

revise

revise_supplier_quote

Create a new immutable revision of a supplier quote. The previous revision remains in history and the new revision becomes current.

source

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, message, and artifact scope.

suppliers

search_suppliers

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

validate

validate_project

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

SupplySlate — questions

Answers built from our own checks of this server.

What can SupplySlate do?

It exposes 55 tools, read directly from the server on our last check. Among them: ask_rfq_clarification, attach_artifact_reference, create_artifact_upload, create_catalog_import, create_project, create_provider_checkout_handoff and 49 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is SupplySlate mostly used for?

Its tools cluster around supplier, project and request. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is SupplySlate working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 653 ms. The bar chart above shows every period we have measured.

How do I connect SupplySlate?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does SupplySlate need an API key?

No. SupplySlate completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 55 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is SupplySlate?

It answers our handshake in 653 ms on average, which is faster than 19% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
