Note the naming trap: this Tomo-run directory is distinct from the open WebMCP protocol effort itself.\n\n- What is verifiable: the live directory lists 50+ registered sites across ~36 pages, offers a free public JSON API, and takes self-registration (WebFetch 2026-09-22). \"Re-checked every day\" is the operator's own claim.\n- What it is not: the registry service is a proprietary hosted product with no public repo or license. The open WebMCP protocol (the W3C / MCP-B line of work, MIT) is a different thing with a similar name — keep them separate when you cite this.\n- The GTM-stack read: this is an AEO/GEO signal, not just a tool. As agents start resolving \"what can I call on the open web,\" a directory of agent-usable sites becomes a distribution surface — the agent-era analogue of being in the index. If your product exposes anything agent-callable, being listed where agents look is cheap to do and worth doing early; just don't assume one vendor's directory is the canonical map.\n- Curated from the GTM Stacker signal registry (2026-09-22 pass: studio pull + viral-posts brief)." } ], "alternates": { "markdown": "https://gtmstacker.com/registry/news/webmcp-registry/index.md", "html": "https://gtmstacker.com/registry/news/webmcp-registry/", "json": "https://gtmstacker.com/registry/news/webmcp-registry/index.json" }, "jsonld": { "@context": "https://schema.org", "@graph": [ { "@type": "WebSite", "@id": "https://gtmstacker.com/#website", "url": "https://gtmstacker.com/", "name": "GTM Stacker Agent Registry", "description": "A daily-updated, agent-native registry of open-source tool discoveries, tool updates, and curated news for the go-to-market / RevOps engineering niche.
