Overview

Description from the maker (original English)

Plainfold data tools: SAM.gov contracts, business entity checks, hiring signals, SEC financials.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Other
  • You need to fill in: Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • You fill in yourself: Authorization

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http plainfold 'https://mcp.apify.com/?tools=plainfold/sam-gov-contract-opportunities,plainfold/business-entity-check,plainfold/company-hiring-signals,plainfold/sec-company-financials' --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "plainfold": {
      "url": "https://mcp.apify.com/?tools=plainfold/sam-gov-contract-opportunities,plainfold/business-entity-check,plainfold/company-hiring-signals,plainfold/sec-company-financials",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "plainfold": {
      "type": "http",
      "url": "https://mcp.apify.com/?tools=plainfold/sam-gov-contract-opportunities,plainfold/business-entity-check,plainfold/company-hiring-signals,plainfold/sec-company-financials",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • Authorization secret HTTP header
    Apify API token as 'Bearer ' (free account at apify.com). Optional if your MCP client supports OAuth sign-in.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Plainfold data tools (all tools) safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.0) reached the registry 29 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

All tools in one server: https://mcp.apify.com/?tools=plainfold/sam-gov-contract-opportunities,plainfold/business-entity-check,plainfold/company-hiring-signals,plainfold/sec-company-financials

Quick start

  1. Get an Apify account (free) at https://apify.com. MCP clients that support OAuth (Claude, VS Code, Cursor) can sign in to Apify in the browser, so you don't need to copy a token. Otherwise, copy your API token from https://console.apify.com/account/integrations.
  2. Add one of the URLs above to your MCP client (examples below).
  3. Ask your agent a question. It calls the tool, and the run is billed to your Apify account at the tool's price.

SAM.gov Contract Opportunities

Search and monitor U.S. federal contract opportunities from SAM.gov's official daily data extract: RFPs, solicitations, sources sought and award notices.

  • Returns federal contract opportunities as clean JSON, one row per notice, from SAM.gov's official nightly public extract (not scraped).
  • Filters by keyword, NAICS, PSC, set-aside (small business, 8(a), HUBZone, SDVOSB, WOSB), agency, state, posted date and deadline.
  • Keyword search is relevance-ranked and ignores the FAR/DFARS boilerplate that every defense notice repeats.
  • Can run on a schedule and return only notices that are new since the last run.

Use it for: Finding federal contracts to bid on, daily bid alerts, market research by NAICS/PSC code, and award notices (who won what, for how much). Not for: State and local bids, non-U.S. tenders, attachment downloads, or historical spending data (use USAspending.gov). Price: $0.002 per opportunity returned + $0.002 per run (about $0.20 per 100 results). No SAM.gov API key needed.

  • MCP URL: https://mcp.apify.com/?tools=plainfold/sam-gov-contract-opportunities
  • MCP tool name: plainfold--sam-gov-contract-opportunities
  • Apify page and full docs: https://apify.com/plainfold/sam-gov-contract-opportunities

Example MCP tool call:

{

"name": "plainfold--sam-gov-contract-opportunities", "arguments": { "keywords": [ "cybersecurity" ], "setAsides": [ "SBA" ], "onlyOpenForResponses": true, "sortBy": "deadlineAsc", "maxResults": 10 } }

Or call it over plain HTTP (returns the results as JSON):

curl -X POST "https://api.apify.com/v2/acts/plainfold~sam-gov-contract-opportunities/run-sync-get-dataset-items" \

-H "Authorization: Bearer $APIFY_TOKEN" -H "Content-Type: application/json" \ -d '{"keywords": ["cybersecurity"], "setAsides": ["SBA"], "onlyOpenForResponses": true, "sortBy": "deadlineAsc", "maxResults": 10}'

US Business Entity Check

Check whether a US company is registered and active, using official state business-registry open data (New York, Colorado, Oregon, Connecticut, Texas).

  • Give it company names; for each one it returns a verdict (active, inactive, status unclear, not found) and the matching registrations.
  • Each registration includes legal name, registry ID, entity type, status, good standing, jurisdiction, formation date and business address.
  • Company records only: it never returns officers, agents, owners or any other personal data.
  • Handles suffix and punctuation differences (Inc vs Inc., L.L.C. vs LLC) and lists similar names separately.

Use it for: Vendor and supplier checks before paying, KYB onboarding, lead qualification, and confirming that a company named in a contract, invoice or email actually exists. Not for: People lookups, states other than NY/CO/OR/CT/TX, credit or financial data, or a legal certificate of good standing. Price: $0.004 per company found, $0.0005 per lookup with no match, + $0.0005 per run. Failed lookups are not charged.

Company Jobs & Hiring Signals

Give a company website, name or job-board URL and get its open jobs in one clean format plus a hiring summary: roles by department and location, new postings, hiring velocity and growth hints.

  • Finds the company's public job board from its website and auto-detects Greenhouse, Lever, Ashby, Workable, SmartRecruiters, Recruitee, Breezy HR, Personio and BambooHR.
  • Returns every open job in one normalized format: title, department, team, location, remote/hybrid/onsite, seniority, posted date, URL and salary when published.
  • Adds a hiring summary per company: open roles by department, location, seniority and workplace type, roles posted in the last 7/30/90 days, hiring velocity and plain-language growth hints.
  • Optional postedSince filter for monitoring new roles. No personal data: no recruiter or hiring-manager names, emails or phone numbers.

Use it for: Sales and account research, investment and market research (hiring velocity as a growth signal), recruiting and competitive intel, and monitoring a list of companies for new roles. Not for: Searching all jobs across the web by keyword (it works company by company), Workday/iCIMS/Taleo-only employers, LinkedIn or Indeed listings, or anything about people. Price: $0.003 per company summary (only when a job board is found) + $0.001 per job returned + $0.0005 per run. Companies with no board found are not charged.
