Overview

AI-generated overview

Remote SalesBook server for searching evidence-graded B2B startup rankings, comparing enterprise vendors, and checking sourced deal claims.

What you can do
  • Search and read company dossiers: ranked B2B startups by sector, full profiles with sources, and dated commercial-win claims
  • Compare and benchmark: side-by-side vendor evaluation, top alternatives to a named vendor, and sector Top-100 rankings with methodology
  • Assess buying context: enterprise buying windows, pilot programs, and best-fit buyer prospects for a company
  • Founder and vendor operations: check a company's listing status and gaps, submit a fact update, report corrections, and opt in to introductions
  • Read governance details: ranking weights, evidence tiers, and confidence labels
  • Check in to the public agent mailbox with a claimed identity and message
When to use it
Useful when an assistant needs sourced market intelligence on B2B and enterprise AI vendors, such as shortlisting vendors, finding alternatives, or checking whether a startup's enterprise traction is backed by evidence. Also relevant for founders reviewing their own listing or looking for buyer prospects.
Requirements
Remote streamable HTTP endpoint; no installation, account, API key, or headers required for the public tools. Clients that only support stdio need a bridge. Listing updates and intro opt-ins require a work email on the company domain for a sign-in link.
Before you install
Most tools are read-only, but update_listing, report_correction, opt_in_for_intros and agent_mailbox_checkin send data to MaxedS; update_listing and opt-in ask for a work email and email confirmation, which proves mailbox access rather than ownership. Rankings and deal claims are third-party research graded by confidence, so low-confidence fields should be verified against cited sources.

Installation

In SourceWeft

  1. Open SalesBook by MaxedS: B2B Startup Rankings & Enterprise Vendor Discovery in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/org.maxeds%2Fsalesbook/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

check_listing

Check a company's SalesBook listing

For founders and vendors: is a company listed in SalesBook, where does it rank, and what is holding it back? Give a company name or website. Returns listing status, sector and rank, evidence grade, agent-readiness (MCP connector, llms.txt), the gaps that limit its ranking with how to fix each, and how to report anything wrong. Ranks are never for sale: only public evidence moves them.

Parameterscompanyrequired

find_prospects

Find best-fit enterprise prospects

For startups looking for customers: the 10 best-fit buyers for a company, with the reason for each. By default, large enterprise buyers (Fortune 500 and similar) from SalesBook's researched set; set buyer_type to startup to find fast-growing SalesBook companies that could buy from you. Give your company (name or website, if listed) and/or what you sell and your target sector. Experimental: fit uses public, company-level signals only. To be considered for an introduction, use opt_in_for_intros.

Parameterslimitsectorcompanybuyer_typewhat_you_sell

update_listing

Update your company's SalesBook listing

For founders and company staff: change a fact on your own company's listing (website, one-line description, headquarters, founded year, team size, LinkedIn, pricing page, product page, customers page). MaxedS emails a sign-in link to your work email on the company's domain; you confirm the change on maxeds.org and it shows immediately, marked as updated by the company. Deals, customers and results that affect rank need a public source and go through review (use report_correction).

Use a work email on your company's domain.
