About StackMCP

StackMCP (mcpforgtm.com) is an independent directory of GTM and sales tools with official MCP servers: 52 listings across 46 tools. It helps GTM engineers and RevOps teams see which products expose remote MCP endpoints, how they authenticate, and what tools agents can call.

Methodology

Each listing cites the vendor's own docs, and shows the date we last checked them. Where possible we probe the MCP endpoint without credentials. A 401 or 403 auth challenge counts as live.

Works in, access, credits, plan and admin controls

These fields come only from each vendor's own docs, help center or pricing pages, never from third-party lists or guesses. Every confirmed value links to the exact page it came from, with the date we read it. Before a value is published, we re-fetch that page and check that the supporting sentence is still there. If the docs don't settle a question, the site shows "Not confirmed". That doesn't mean "no". "Works in" means the vendor's docs name that app or give setup steps for it, not just that the server would probably work. Admin controls count only settings the vendor provides, not settings inside Claude or ChatGPT. The "Useful for" role tags are our own editorial grouping.

The generic "Connect without code" steps for Claude and ChatGPT come from Anthropic's and OpenAI's own docs, and each page links them.

Status monitoring

A daily job sends one unauthenticated MCP initialize request to each remote endpoint, with the User-Agent StackMCP-monitor (+https://mcpforgtm.com/about.html) and a 10-second timeout. If the server returns 401, we may make one extra request for its public OAuth protected-resource metadata. We call tools/list only on servers that allow it without credentials. We never send credentials. Results are on the status page.

What we are not

How the site is funded (planned)

Clearly labeled sponsored listings, newsletter sponsorships, and affiliate links to listed GTM tools (for example Instantly or Apollo) where programs exist. Affiliate links will always be labeled. Sponsorship never buys a “verified” badge without meeting criteria.

Listing requests and updates

Vendors: see List your MCP server. Everyone else: the weekly newsletter covers new listings, auth changes and breakages.
