Model Context Protocol (MCP) server for Apollo.io API integration
Nothing to run from here
Signed Investors 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.

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 signed-investors-mcp https://mcp.signed.com/investorsReconnect, 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
7 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Search Signed's public angel investor directory by keyword: a name, a login, or a word from an investor's bio or investment description ("climate", "former founder", "pre-seed"). A query that names a sector also matches investors who list that sector. Only public profiles are searched. Add sector or check_size to narrow the hits; use list_investors to browse a facet without a keyword.
No parameter schema on file.
Browse Signed's public angel investor directory: every investor with a public profile, most complete profiles first, optionally narrowed to one sector or one check size. Each result carries the investor's login (for get_investor), what they invest in, the checks they write, their pinned portfolio companies, and whether they take pitches. Use search_investors when you have a name or a keyword.
No parameter schema on file.
One angel investor's public Signed profile by login: bio, investment description, sectors, check size, links, the portfolio companies they've pinned, whether (and where) they take pitches from founders, follower counts, and a few similar investors. Logins come from search_investors or list_investors, or from a signed.com/@login URL. Private profiles are indistinguishable from nonexistent ones.
No parameter schema on file.
Public Signed investors who follow the given investor, alphabetically by name. Only public profiles appear on either side, the same as signed.com/@login/followers.

The sectors an investor can list on their Signed profile — the valid values for the sector filter on list_investors and search_investors — with how many public investors list each, a one-line description, and example companies. Busiest sectors first.

The check-size ranges an investor can list on their Signed profile — the valid values for the check_size filter on list_investors and search_investors — smallest to largest, with how many public investors write each.

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. So there is no grade — not a withheld one, an unmeasured 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 Signed Investors 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.
