Model Context Protocol (MCP) server for Apollo.io API integration
Nothing to run from here
StackSwap is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

What it does
B2B GTM stack intelligence: search ~400 tools, compare vendors, find overlaps, audit SaaS spend.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http stackswap-mcp https://stackswap.ai/api/mcp
# 2 — ask your agent for something these tools do
# inspect_available_connections, request_system_connection, start_stack_audit and 20 more
StackSwap costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http stackswap-mcp https://stackswap.ai/api/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
What you approve
23 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.
Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.

|---|---|---|---|
| query | string | no | Substring to match against tool names (case-insensitive). Omit to list top tools. |
| limit | integer | no | Max number of results to return. |
Full StackSwap profile for a single tool: cost (catalog + per-seat with confidence; vendor fact sheet wins when fresh), AI-readiness score, category, common overlaps, swap-registry status, and partner sign-up link. Use when the user wants depth on one tool (more than search_tools' name + cost).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| name | string | yes | Tool name (fuzzy-matched against catalog). |
Return the full vendor fact sheet (per GTM Decision Schema v1.0.0) for a tool, when one exists. Includes pricing tiers with gotchas, integration depth scores, AI capabilities + customer-data-for-training disclosure, affiliate program terms, and self-disclosed conflicts (vendor-claim vs user-reported). Provenance is labeled (vendor / stackswap / community) and freshness is computed against a 90-day
| Parameter | Type | Required | Notes |
|---|---|---|---|
| tool | string | yes | Tool name or slug (e.g. "Apollo.io", "apollo", "Smartlead"). Fuzzy-matched against the catalog. |

| Parameter | Type | Required | Notes |
|---|---|---|---|
| tools | array | yes | Tool names in the current stack (e.g. ["HubSpot", "Salesforce", "Outreach"]). |

| budget | number | no | Optional monthly budget cap in USD. If exceeded, the response flags the overage but does not auto-swap tools. |
Head-to-head comparison of two GTM tools. Returns cost delta, AI-readiness and headless-readiness (MCP/API callability — can an agent or your own dashboard drive it) scores, overlap status, swap-registry signal, and StackSwap's recommended pick with reasoning. Use when the user is choosing between two specific vendors (e.g. 'Salesforce vs HubSpot', 'Outreach vs Smartlead').
| Parameter | Type | Required | Notes |
|---|---|---|---|
| a | string | yes | First tool name (fuzzy-matched against catalog). |
| b | string | yes | Second tool name (fuzzy-matched against catalog). |
Side-by-side comparison of 2–6 GTM tools in one shot.

Return StackSwap's renewal-negotiation playbook for a specific vendor: leverage points (why they will discount), price-anchor alternatives to cite, a calibrated discount ask, a walkaway script, optimal timing window, and contract-trap callouts. Pass monthlySpend to compute target savings. Optional contractEndsIn flags compressed-timeline adjustments. Authored from operator experience across ma

Submit a correction to the StackSwap catalog (pricing, feature list, gotcha, AI-readiness score, category, or other). Submissions queue for admin review and only propagate to user-facing surfaces after merge — they DO NOT immediately mutate the catalog. Use when the user notices a stale price, an inaccurate feature list, a gotcha that should be flagged, or wants to report a tool we don't cover. Tw
| Parameter | Type | Required | Notes |

No rule-by-rule report on file for this release
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither: the repository linked on this page is where this record was collected from, not a copy of what the address serves, so it is not graded in its place. So there is no grade — not a withheld one, an unmeasured one.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 1.1.0.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish StackSwap can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
