The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
build_portfolio_list Build a portfolio company list ~652
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 portfolio company (name, domain, website, description, and stage, batch, or status where the source gives it) plus one free summary row per source saying how it was read or why it returned nothing. Y Combinator is filterable by batch, industry, region, status, and search words. Pages are read from the investor's own site and robots.txt is obeyed. A run that does not succeed is returned as an error with its run ID. Read-only; requires an APIFY_TOKEN and is billed per company row with a domain.

VerifyMCP ran 15 checks on com.mambabuilt/mcp-vc-accelerator-portfolio-list-builder, covering Known CVEs, Install scripts, Dependency health, Source repository and 11 more. One item could not be completed, a gap on our side rather than a finding about com.mambabuilt/mcp-vc-accelerator-portfolio-list-builder: Malware scan. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
