Provides tools to search, compare, and analyze HubSpot as part of a GTM stack, including cost, overlaps, AI-readiness, and swap recommendations.
Provides tools to search, compare, and analyze Salesforce as part of a GTM stack, including cost, overlaps, AI-readiness, and swap recommendations.
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.

Seventeen tools across eight domains. Schemas are in schemas/tools.json (extracted directly from the live tools/list response).
Tool | What it does |
| Fuzzy-search ~400 GTM tools by name. Returns each match with monthly cost and a StackSwap partner sign-up link when applicable. |
| Full StackSwap profile for a single tool: cost (catalog + per-seat with confidence), AI-readiness score, category, common overlaps, swap-registry status. |
| Full vendor fact sheet (GTM Decision Schema v1.0.0): pricing tiers with gotchas, integration depth scores, AI capabilities + customer-data-for-training disclosure. |
Tool | What it does |
| Given a stack, return the redundant pairs StackSwap has hand-verified (104-pair overlap registry) with consolidation savings. |
| Per-tool AI-native replacement recommendations (Outreach → Smartlead, ZoomInfo → Apollo) with annual savings and reasoning. |
| Preview StackScan: tools + team size + industry in, current spend / optimized spend / monthly-annual recoverable / headless gaps out. |
| Given a need ("outbound", "CRM", "automation"), return StackSwap's recommended partner(s) with positioning. |
| Reference starter stack for an industry vertical with per-tool cost, total spend, AI-readiness and headless-readiness scores. |
Tool | What it does |
| Head-to-head: cost delta, AI-readiness, headless-readiness (MCP/API callability), overlap status, and a recommended pick with reasoning. |
| 2–6 tools side-by-side in one markdown matrix — cost, AI-readiness, headless-readiness, overlaps within the set, StackSwap pick. |
Tool | What it does |
| Full-text search across ~50 first-party operator articles on stack architecture, AI-native swaps, RevOps, and decision frameworks. |
| Fetch a knowledge-base article's full body as markdown, with canonical URL, category, and last-modified date. |
Tool | What it does |
| Full map of one GTM category — leaders, runner-ups, skip/replace candidates — with cost, AI-readiness, swap-registry status per tool. |
Tool | What it does |
| Infer a GTM stack from freeform text (careers page, job posting, site HTML, RFP, DevTools network tab). Ranked matches with confidence levels. |
Tool | What it does |
| 10–20 questions to ask a vendor before signing, with "why it matters" and red-flag answers. Vendor-specific gotchas when you pass a vendor. |
| Renewal-negotiation playbook per vendor: leverage points, price-anchor alternatives, calibrated discount ask, walkaway script, timing window. |
Tool | What it does |
| Submit a catalog correction (pricing, features, gotchas, scores). Queued for admin review — never propagates to user-facing surfaces unreviewed. |
Once installed, ask any of the following in your AI client and it will route to the right tool:
Operator question | Tool that fires |
"Find me a cold-email tool" |
|
"What does Smartlead cost?" |
|
"Smartlead vs Apollo for outbound?" |
|
"Compare Smartlead, Instantly, Apollo, and Lemlist" |
|
"Map the whole sales-engagement category" |
|
"What should I ask Apollo before signing?" |
|
"My Salesforce renewal is in 60 days — what's my leverage?" |
|
"What stack does this company run?" (paste a careers page) |
|
"What overlaps if I'm on HubSpot + Salesforce + Outreach?" |
|
"Audit my stack: HubSpot, Salesforce, Outreach, ZoomInfo, Gong" |
|
"Find StackSwap's article on data ethics in outbound" |
|
Tool descriptions are model-readable, so you don't need to know the tool names — the model picks based on the question.
A minimal TypeScript example that connects, lists tools, and runs find_overlaps is in examples/client.ts.

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.
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.
