BuyAPI tools (7)

write = sends, deletes, buys or posts
  • stacks.findSimilarFree

    Finds reviewed public stack examples related to a vendor, or recent curated stack examples. Use this when the user asks who uses a tool, what similar builders use, or wants examples of real stack combinations. Do not use it as a generic recommendation tool.

  • stacks.recommendFree

    Recommends a complete stack from BuyAPI's corpus with a structured decision matrix, cost estimate, assumptions, unknowns, alternatives, and sources. Use this when the user is starting a project or asks for a complete multi-layer stack choice. Do not use this for local coding/debugging/docs questions that do not involve software or vendor selection. Do not call vendors.resolve first; this tool handles retrieval and ranking.

  • vendors.compareFree

    Compares two or more already-known BuyAPI vendors for a specific workload or decision. Use this when the candidate set is known, for head-to-head questions like "Convex vs Supabase vs Neon for a realtime SaaS" or "Stripe vs Paddle for a marketplace". If the user has not named candidates, use vendors.resolve first.

  • vendors.detailsFree

    Follow-up tool for one known vendor. Retrieves detailed pricing, features, limits, gotchas, comparisons, and source provenance. Call vendors.resolve first unless the user already provided a BuyAPI vendor ID like /database/supabase. Use this after a candidate is selected and the user needs claim-level pricing, limit, gotcha, or provenance details.

  • vendors.estimateCostFree

    Produces directional monthly cost estimates from BuyAPI pricing data and explicit workload inputs. Use this only when the user asks for cost math and provides explicit workload inputs. Missing workload fields are returned as assumptions or unknowns instead of being hallucinated. Treat results as BuyAPI claim-based estimate math; verify exact billing in first-party docs, vendor CLIs, or vendor MCPs before purchase or production decisions.

  • vendors.evidenceFree

    Returns recent reviewed BuyAPI evidence rows for a vendor, category, stack, or comparison. Use this when the user asks why BuyAPI believes something, what sources support a recommendation, or what recent human/source/opinion/history signals exist. This is a trust and provenance follow-up, not the first recommendation tool.

  • vendors.resolveFree

    First stop for category-specific vendor recommendations and vendor ID discovery. Finds BuyAPI vendor IDs for a user question; provide category when known. Use this when the user asks which provider in a category fits their constraints. With a covered category, the response includes ranked results plus a top-3 decision matrix with fit labels, confidence, tradeoffs, cost notes, freshness, and sources. Do not use this for local coding/debugging/docs questions unless they involve choosing a software vendor or tool. If the category is outside BuyAPI's corpus, the tool returns an explicit "not in corpus yet" result instead of inventing vendors.

BuyAPI CLI + MCP Server

Unbiased vendor intelligence for AI coding agents.

BuyAPI helps AI agents and developers make informed infrastructure decisions. When your agent needs to pick a database, auth provider, hosting platform, payment processor, email provider, or UI component system, BuyAPI provides current, structured, neutral vendor comparisons - not training data defaults.

Quick Start

Remote MCP (Recommended)

The hosted endpoint is the primary install path and exposes the current seven-tool contract.

Add to your MCP client config:

{
  "mcpServers": {
    "buyapi": {
      "url": "https://buyapi.ai/api/mcp"
    }
  }
}

This is the easiest path: the client connects directly to BuyAPI over HTTP, with no local process and no npm install.

CLI Setup

Run setup to install BuyAPI into your agent:

npx buyapi

Bare npx buyapi opens an interactive setup flow. It asks which coding agent you use, installs the hosted MCP config by default, can add the /stack planning skill where supported, and can log you in for higher limits and stack sync.

Or target a client directly:

npx buyapi setup cursor
npx buyapi setup claude-code
npx buyapi setup codex
npx buyapi setup windsurf
npx buyapi setup cline

By default setup writes the hosted MCP URL. Use --local when a client needs a local stdio process:

npx buyapi setup codex --local

Claude Code and Codex can also install the /stack planning workflow:

npx buyapi setup claude-code --skill
npx buyapi setup-skill codex

/stack inspects the local repo, asks for missing constraints, calls BuyAPI MCP for current vendor data, and returns a sourced Stack Decision Record. It does not sync scan data unless you explicitly ask it to.

If you use the CLI often and do not want to type npx, install it globally:

npm install -g buyapi
buyapi scan

In an MCP client config, use the explicit mcp command. The client launches it as a local stdio server; you do not run it manually first:

{
  "mcpServers": {
    "buyapi": {
      "command": "npx",
      "args": ["-y", "buyapi", "mcp"]
    }
  }
}

Use the local path when an agent client does not support remote MCP URLs, or when you want the open-source local transport. Hosted MCP is still the recommended default. The older buyapi-mcp package is deprecated on npm so new users see one canonical package name.

Stack Scan And Sync

The CLI has a stack scanner. Plain scan prints a local preview first, then asks whether to save the private stack when the terminal is interactive:

npx buyapi scan

Run it from the app, package, or monorepo root that contains project signals such as package.json, a lockfile, framework config, convex/, prisma/, Python manifests, or source imports. You can also point it at a public GitHub repo URL:

npx buyapi scan https://github.com/owner/repo

If no project signals are found, the CLI prints wrong-folder guidance instead of silently returning an empty stack. Sync also skips stacks with zero known BuyAPI tools unless you pass --allow-empty.

Use --verbose to see evidence and unknown package candidates found in package.json:

npx buyapi scan --verbose

For a guaranteed no-upload preview, use --dry-run. To save a private stack without prompts in automation, login once, then sync:
