7 Best MCP Servers for Solo Founders (2026)

Official MCP servers that let your agent read your bank, CRM, database, deployments and designs, so you can run the business by asking.

By agentools

  • Stripe MCP: customers, payment links, invoices and refunds from a chat.
  • Mercury: asking your bank about spend, balances and statements.
  • Attio: a CRM your agent can read and update.
  • Supabase MCP: letting an agent design tables, run SQL and read logs.
  • Vercel MCP: deployments, build logs and docs without leaving the editor.
  • Context7: current library docs, so your coding agent stops guessing APIs.
  • Figma MCP: generating code that matches the design.

An MCP server turns an app you already use into tools your agent can call. Connect the right ones and "how much did I spend on software last month?" or "why did the last deploy fail?" becomes a question, not a dashboard tour.

These seven are official servers from the companies themselves, all in the agentools directory. I favored ones that cover the core of a small business, money, customers, product and design, and that let you limit what the agent can do.

The 7 picks

1. Stripe MCP

Payments, customers and invoices for agents

Stripe's MCP server lets an agent create customers, products, prices and payment links, send invoices, issue refunds and manage subscriptions, and search Stripe's docs and support articles.

Use a restricted key to decide exactly what the agent may touch. The server is free; normal Stripe fees apply.

Pricing: FreeHosted MCP server

2. Mercury

Startup banking your AI tools can query

Mercury is startup banking with cards, bill pay and invoicing, and its official MCP server gives Claude, ChatGPT or Cursor read access to spend and balances. Any payment request an agent makes still needs a human to approve it.

Core banking is $0 a month. Mercury is a fintech, not a bank; banking runs through partner banks.

Pricing: $0/moBanking + hosted MCP server

3. Attio

Flexible CRM with a first-party MCP server

Attio syncs contacts from email and calendar, enriches records on its own, and exposes your pipeline through a remote MCP server with OAuth. Ask for the deals that went quiet this week, or have the agent log notes after a call.

Free for up to 3 seats; Plus starts at $44 a user a month.

Pricing: Free tierSaaS app

4. Supabase MCP

Postgres, auth and storage for agents

Supabase's server lets agents design schemas and migrations, run SQL, manage branches and edge functions, and fetch logs. Two settings matter: an optional read-only mode, and scoping access to a single project.

The server is free; your normal Supabase usage applies.

Pricing: FreeHosted MCP server

5. Vercel MCP

Deployments, logs and docs for your agent

Vercel's official server lets your agent inspect projects, deployments and build logs, and search the Vercel docs. It's hosted with OAuth sign-in and works with Claude, Cursor and VS Code, so "why did the last deploy fail?" gets an answer with the log lines that matter.

Pricing: FreeHosted MCP server

6. Context7

Up-to-date library docs for coding agents

Context7 feeds version-specific documentation and code examples for thousands of libraries into your coding agent through its hosted MCP server or the ctx7 CLI. It's the cheapest fix for an agent that writes code against an API that changed last year.

Free for 1,000 calls a month on public repos; Pro is $10 a seat a month.

Pricing: Free tierHosted MCP server

7. Figma MCP

Design context for code agents

Figma's server gives coding agents frames, variables and components as context, plus Code Connect mappings to your codebase and screenshots for visual checks. Run it remote, or locally through the desktop app.

Pricing: Free tierHosted MCP server

More to consider

How to set them up safely

  • Start read-only. Supabase has a read-only mode; Mercury and Puzzle read by default. Add write access only where it saves you real time.
  • Scope the keys. Stripe restricted keys and single-project access in Supabase keep a mistake small.
  • Keep a human on money. Mercury already requires approval for payments; do the same for refunds and invoices.

Wrapping up

If you install only three: Stripe for revenue, Mercury for spend and Attio for customers. Add Supabase and Vercel once you ship product. Every server here has a one-line install for Claude Code, Codex, Cursor and Grok Bot on its directory page.
