Model Context Protocol (MCP) server for Apollo.io API integration
Nothing to run from here
VC Accelerator Portfolio List Builder 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
Portfolio company lists from Y Combinator, a16z, Sequoia, Accel, and any VC portfolio page
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --env 'APIFY_TOKEN=${APIFY_TOKEN}' --transport stdio vc-accelerator-portfolio-list-builder-mcp '--' npx -y @mambalabsdev/mcp-vc-accelerator-portfolio-list-builder
# 2 — ask your agent for something these tools do
# build_portfolio_list
It needs APIFY_TOKEN: this reads it from your environment, so export it first.
VC Accelerator Portfolio List Builder costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.
Publisher
Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. This one runs on your machine: your client starts VC Accelerator Portfolio List Builder as a process under your own user, with your files and your network, so the tool surface below is what it can do to your computer rather than to a server somewhere else. Its scan result is on the Security tab — read the surface before you approve it.
Claude Codedeclared by this listing
This is a public server: you run it yourself and this marketplace is not in the path. You need Node.js — the current LTS (24) is the safe choice; npx comes with it. Claude Code registers it in one command; --scope user makes it available in every project. Claude Code reads APIFY_TOKEN (Apify API token from https://console.apify.com/account/integrations) from your environment each time it starts the server, so the value stays out of its config: export it in your shell profile (macOS, Linux), or run setx APIFY_TOKEN … and open a new terminal (Windows). The '--' is in quotes so that PowerShell passes it on.
claude mcp add --scope user --env 'APIFY_TOKEN=${APIFY_TOKEN}' --transport stdio vc-accelerator-portfolio-list-builder-mcp '--' npx -y @mambalabsdev/mcp-vc-accelerator-portfolio-list-builderReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it runs from its publisher’s own package: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it asks of you
It reaches a system of yours, so it needs your own credential rather than the publisher’s: APIFY_TOKEN — Apify API token from https://console.apify.com/account/integrations. You set it in your own client’s config, on your machine — this marketplace never holds it.
What it writes
One config entry your client uses to start the process locally. A local server runs with your file system and your network, which is why it is priced without metering.
What you approve
1 tool, 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.
Read from its source code. A server that builds its tool list when it starts can list more tools than this.
Build a list of the companies a venture capital firm or accelerator backs. Give investor or accelerator names (Y Combinator, a16z, Sequoia, Accel, Index Ventures, Founders Fund, Greylock, Lightspeed, Khosla, First Round, Techstars, Antler) or any portfolio page URL. Returns one flat row per…

|---|---|---|---|
| investors | array | no | Investors or accelerators by name (Y Combinator, a16z, Sequoia, Accel, Index Ventures, Founders Fund, Greylock, Lightspeed, Khosla, First Round, Techstars, Antler) or portfolio page URLs. Up to 25. De |
| yc_batches | array | no | Y Combinator only. Batches as S24, W25, or Summer 2024. Empty: every batch. |
| yc_industries | array | no | Y Combinator only. Industries as the directory writes them, for example B2B, Fintech. |
| yc_regions | array | no | Y Combinator only. Regions as the directory writes them, for example Europe. |
| yc_status | array | no | Y Combinator only. Any of active, acquired, public, inactive. |
| yc_query | string | no | Y Combinator only. Words to search the directory for. |
| max_companies_per_source | integer | no | Company rows per source. Default 500. |
| open_company_pages | boolean | no | Open per company pages when a portfolio page links only to them. Default true. |
| max_detail_pages | integer | no | Company pages opened per source. Default 200. |
| only_new | boolean | no | Skip companies an earlier run returned for the same source (free). Default false. |
| state_key | string | no | Optional name for the only new companies memory. |
| max_charge_usd | string | no | Optional. The run stops before a charge that would pass this amount. |
| proxy_mode | string | no | auto reads a site that refuses a direct request through the Apify proxy; direct never uses a proxy. A reliability setting; it does not change the price. Default auto. |

ATrust score 96 / 100
Release 1.0.1 · scanned 29 Oct 2026
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.

score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
Tool surfaceread
Implementation sourceread
Package metadataread
Live transportnot available
Tools were statically extracted from the published source (1 recovered), not enumerated from a running server. Tool-poisoning, Unicode-smuggling, capability and toxic-flow analysis ran on this inferred surface, but a mis-parsed registration could be missed or mis-attributed, so tool-derived findings are capped below “confirmed”. To grade the real runtime surface, scan the running server: --command "npx -y <package>".
Capability — what it could do if the model were manipulated
Tags derived from each tool’s schema and the implementation, not from what the tool calls itself. moderate is the level these add up to.
| Tool | Capability tags | Why the tag was assigned |
|---|---|---|
| build_portfolio_list | untrusted-inputexternal-sink | untrusted-input: declares openWorldHint: true (interacts with entities outside the server); external-sink: handler sends an HTTP POST (fetch(https://api.apify.com/v2/acts/${actorPath}/runs?timeout=${ACTOR_RUN_TIMEOUT_SECS}) at build/index.js:79 |
Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
flow-1
Untrusted input can drive an external action even though no sensitive source is exposed.

This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.
Release history
Always latest — the install command names no version, so it installs the newest release when it runs; the current release on file is 1.0.1. Pin a release below and the command asks for exactly that one.

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 VC Accelerator Portfolio List Builder 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.
