Available tools 14

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

resolve

resolve_gtin

Resolve a GTIN to its procurement readiness signal. Zero-pads input to 14 digits.

resolve_node

Resolve one node: its GS1 license + its makers (supply) + its retailers (demand).

resolve_scope

GSC Scoped Agents Registry — 1,000,000 scoped identities under SM-ECO-10060.

resolve_sparks

Two-branch SPARKS resolver (zero-pads GTIN to 14). Branch A GSC Territory/License GTIN (990832300xxx) -> FULL license record (public). Branch B any third-party BPC GTIN -> GATED proof {recognized, region_node, kernel_available}; the pack/size VALUE is NEVER returned. Route to Navigator. Brand match is fail-closed (normalized exact match); uncertainty -> recognized:false.

brands

list_brands_by_node

SPARKS depth surface: the distinct brands SPARKS covers in a sovereign market. Answers 'what brands do you know in [node]'. Coverage only — no pack/size values.

count

count_gtin_coverage

Global coverage statistics: GTINs, nodes, makers (supply), retailers (demand).

eligibility

check_eligibility

Check whether a GTIN can ship to a specific retailer banner in a country.

kernel

get_kernel

SPARKS completeness tier for a brand in a market: 100 = resolvable (a real pack/size record is held) . 8 = registered (brand known, pack/size pending) . 'floor' = STANDARD default (no brand-specific record). Returns the stored tier flag — do NOT compute a score. Never returns a pack/size.

makers

find_makers

Global cross-node maker (supply) search. Filter by segment / region / node / has_website.

node

node_market

Supply↔demand bridge for ONE jurisdiction: makers (supply) and retailers (demand) as two separate counts (never summed), plus the same-node potential bridge pairs.

nodes

list_nodes

The 49 sovereign nodes (the spine) — each with its GS1 GTIN and CLEAN per-node maker (supply) and retailer (demand) counts (separate subqueries, never summed).

retailers

find_retailers

Global cross-node retailer (demand) search. Filter by region / node / parent_banner.

signal

get_signal_chain

Return the full ACM-68000 signal chain for a GTIN (zero-pads to 14).

sku

list_sku_types

SPARKS taxonomy: the 84 standing BPC product-type codes the graph is structured on. Validate a type against this before a typed query. (BRAND is a tier, not a type.)

MCP CPG Knowledge Graph — questions

Answers built from our own checks of this server.

What can MCP CPG Knowledge Graph do?

It exposes 14 tools, read directly from the server on our last check. Among them: check_eligibility, count_gtin_coverage, find_makers, find_retailers, get_kernel, get_signal_chain and 8 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 →

Is MCP CPG Knowledge Graph 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 292 ms. The bar chart above shows every period we have measured.

Is MCP CPG Knowledge Graph still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect MCP CPG Knowledge Graph?

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 MCP CPG Knowledge Graph need an API key?

No. MCP CPG Knowledge Graph completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 14 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is MCP CPG Knowledge Graph?

It answers our handshake in 292 ms on average, which is faster than 47% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
