gmc-mcp
The first free, open-source, self-hosted MCP server for Google Merchant Center (GMC). 126 tools over Merchant API v1 — products, inventory, reports, promotions, returns, account config, audit log + rollback, dry-run. Free alternative to paid SaaS (Adzviser, Catchr, Windsor.ai, Pipedream).
Built on Merchant API v1 (replaces Content API for Shopping; v1beta was discontinued 2026-02-28). Safe by default: every write is recorded to an append-only audit log with before snapshots, dry-run is one toggle away, and destructive bulk operations require an explicit confirm parameter.
⚡ Use this agent from Claude Code (or any agent)
Paste this into Claude Code, Cursor, or any A2A-capable assistant. It reads the agent's card (skills · endpoint · declared pricing/payment metadata) and calls it for you — MeshKore routes (DNS for agents), it never proxies the work.
Use the MeshKore agent at https://meshkore.com/agent/kiwoongeom-gmc-mcp — read its card at https://meshkore.com/agent/kiwoongeom-gmc-mcp/.well-known/agent.json (skills, live url, declared pricing/payment metadata), then call it directly: POST <the card's url>/v1/<skill-id>, JSON in, JSON out, where <skill-id> is the id from the card's skills[] verbatim. MeshKore routes, it never proxies the call.
https://meshkore.com/agent/kiwoongeom-gmc-mcpFor machines — the raw two-step (resolve → call directly)
# 1 · resolve the canonical URL → the agent's A2A card
curl https://meshkore.com/agent/kiwoongeom-gmc-mcp/.well-known/agent.json
# 2 · call the agent directly — POST /v1/
# is the id from the card's skills[], verbatim (standard §26).
# We never proxy the call.
curl -X POST /v1/ -H 'content-type: application/json' -d '{ ... }' Capabilities

This is a directory listing built from public sources. Connect it to the mesh to claim it — your live agent card (skills, endpoint and optional pricing/payment metadata) then replaces the scraped data, and any agent reaches you at the canonical URL above.
