Overview

Description from the maker (original English)

B2B GTM stack intelligence: search ~400 tools, compare vendors, find overlaps, audit SaaS spend.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Search & AI memory

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

Common questions

Is StackSwap safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.0) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

StackSwap MCP

A hosted Model Context Protocol server that gives AI clients access to StackSwap's B2B SaaS GTM stack intelligence — tool catalog, vendor fact sheets, overlap detection, AI-native swap suggestions, stack audits, n-way comparisons, category landscapes, buyer questions, renewal-negotiation playbooks, and a full-text operator knowledge base.

Live endpoint: https://stackswap.ai/api/mcp Docs: stackswap.ai/mcp Status: Free, no API key, stateless. 17 tools — 16 read-only + 1 write (submit_correction, queued for human review).

This repo contains public documentation, JSON schemas, and an example client for the hosted MCP server. The server itself is closed-source — it runs as part of stackswap.ai and wraps the same scan engine and tool catalog that powers the web product.


Install

Claude Code
claude mcp add --transport http stackswap https://stackswap.ai/api/mcp

For user-scope (available in every session, not just one project):

claude mcp add --transport http --scope user stackswap https://stackswap.ai/api/mcp
Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{

"mcpServers": { "stackswap": { "url": "https://stackswap.ai/api/mcp", "transport": "http" } } }

Restart Claude Desktop. A tools indicator appears in the chat compose box.

Cursor / ChatGPT Desktop / Other MCP clients

Add a new HTTP MCP server with URL https://stackswap.ai/api/mcp. No authentication.


Tools

Seventeen tools across eight domains. Schemas are in schemas/tools.json (extracted directly from the live tools/list response).

Catalog
ToolWhat it does
search_toolsFuzzy-search ~400 GTM tools by name. Returns each match with monthly cost and a StackSwap partner sign-up link when applicable.
get_tool_detailsFull StackSwap profile for a single tool: cost (catalog + per-seat with confidence), AI-readiness score, category, common overlaps, swap-registry status.
get_vendor_fact_sheetFull vendor fact sheet (GTM Decision Schema v1.0.0): pricing tiers with gotchas, integration depth scores, AI capabilities + customer-data-for-training disclosure.
Stack analysis
ToolWhat it does
find_overlapsGiven a stack, return the redundant pairs StackSwap has hand-verified (104-pair overlap registry) with consolidation savings.
suggest_swapsPer-tool AI-native replacement recommendations (Outreach → Smartlead, ZoomInfo → Apollo) with annual savings and reasoning.
scan_stackPreview StackScan: tools + team size + industry in, current spend / optimized spend / monthly-annual recoverable / headless gaps out.
recommend_partnerGiven a need ("outbound", "CRM", "automation"), return StackSwap's recommended partner(s) with positioning.
recommend_stackReference starter stack for an industry vertical with per-tool cost, total spend, AI-readiness and headless-readiness scores.
Compare
ToolWhat it does
compare_toolsHead-to-head: cost delta, AI-readiness, headless-readiness (MCP/API callability), overlap status, and a recommended pick with reasoning.
compare_tools_n_way2–6 tools side-by-side in one markdown matrix — cost, AI-readiness, headless-readiness, overlaps within the set, StackSwap pick.
Content
ToolWhat it does
search_contentFull-text search across ~50 first-party operator articles on stack architecture, AI-native swaps, RevOps, and decision frameworks.
get_kb_articleFetch a knowledge-base article's full body as markdown, with canonical URL, category, and last-modified date.
Categories
ToolWhat it does
get_category_landscapeFull map of one GTM category — leaders, runner-ups, skip/replace candidates — with cost, AI-readiness, swap-registry status per tool.
Detect
ToolWhat it does
detect_stack_from_textInfer a GTM stack from freeform text (careers page, job posting, site HTML, RFP, DevTools network tab). Ranked matches with confidence levels.
Decision support
ToolWhat it does
get_buyer_questions10–20 questions to ask a vendor before signing, with "why it matters" and red-flag answers. Vendor-specific gotchas when you pass a vendor.
get_renewal_strategyRenewal-negotiation playbook per vendor: leverage points, price-anchor alternatives, calibrated discount ask, walkaway script, timing window.
Write
ToolWhat it does
submit_correctionSubmit a catalog correction (pricing, features, gotchas, scores). Queued for admin review — never propagates to user-facing surfaces unreviewed.

Example usage

Once installed, ask any of the following in your AI client and it will route to the right tool:

Operator questionTool that fires
"Find me a cold-email tool"recommend_partner
"What does Smartlead cost?"get_tool_details
"Smartlead vs Apollo for outbound?"compare_tools
"Compare Smartlead, Instantly, Apollo, and Lemlist"compare_tools_n_way
"Map the whole sales-engagement category"get_category_landscape
"What should I ask Apollo before signing?"get_buyer_questions
"My Salesforce renewal is in 60 days — what's my leverage?"get_renewal_strategy
"What stack does this company run?" (paste a careers page)detect_stack_from_text
"What overlaps if I'm on HubSpot + Salesforce + Outreach?"find_overlaps
"Audit my stack: HubSpot, Salesforce, Outreach, ZoomInfo, Gong"scan_stack
"Find StackSwap's article on data ethics in outbound"search_content

Tool descriptions are model-readable, so you don't need to know the tool names — the model picks based on the question.


Example client

A minimal TypeScript example that connects, lists tools, and runs find_overlaps is in examples/client.ts.

npx tsx examples/client.ts

The protocol is plain JSON-RPC 2.0 over HTTP — any language with a JSON parser and an HTTP client can call it.

Why hosted, not stdio

StackSwap's MCP server runs inside the existing stackswap.ai Next.js application as a single route handler. Hosting it ourselves means:

  • No install friction — one claude mcp add line, no npm/pip dependency
  • Always current — the underlying tool catalog, overlap registry, vendor fact sheets, and swap data update as the StackSwap product evolves
  • Zero local compute — the scan engine runs server-side; clients just send JSON-RPC

The trade-off: it requires an internet connection, and we (StackSwap) see request volume and tool-call patterns. We don't store conversation data or user identifiers — the endpoint is stateless.


Requests, issues, feedback

Open an issue if you want a tool added, a behavior changed, or you've hit a bug. The MCP surface is shaped by what operators actually ask about.
