Identifier: run.agentdata/agentdata
Transport: Streamable HTTP
Runtime: Web executable
Trust: Verified
Published: Sep 28, 2026

Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to agentdata.run, but the endpoint is not on that domain, so the publisher may not run this server.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

AgentData gives an assistant B2B customer lists: which companies use a given technology, with evidence, dates and company details.

What you can do: Find technologies by name or category, with usage counts and whether they are on your lists
Pull the companies using a technology, newest first, with how and when each was detected
See companies that recently started using a technology over 7, 30 or 90 days
Look up one company by domain for its technologies by category, plus contacts on a plan
Add technologies to your lists and start CSV downloads of list data
Check your plan, lists, remaining downloads and daily limits
When to use it: Useful for sales, marketing and market research work where you need to know which companies use a particular B2B tool, spot recent adopters, or profile a single company's tech stack from an AI assistant.
Requirements: Remote hosted endpoint at mcp.useagentdata.com over streamable HTTP, with OAuth sign-in or an API key sent as an Authorization Bearer header. An AgentData account and plan are required; the key is found in account settings. A local stdio bridge is available via npx with the API key.

Before you install

Requires an AgentData account and API key, which grants access to your plan's lists and download quota; generating a new key disconnects anything using the old one. Adding technologies to lists and starting CSV downloads change your account state and consume download records, while browsing counts against a daily limit. Company contact data is only available on paid plans.

Installation

In SourceWeft

Open AgentData in the dashboard and add it to a workspace.
Connect the required credentials. They are stored privately and never shown on public pages.
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/run.agentdata%2Fagentdata/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. The client completes OAuth sign-in on first connect.

README

AgentData MCP server

Customer lists of B2B software for AI agents. Ask who uses a technology (HubSpot, Zendesk, Stripe, Shopify and thousands more) and get the companies, each with how we found it, in the website's code or its public DNS records, and when we first and last saw it. Also: the companies that just started using a technology, one company's technologies grouped by category, and CSV downloads of the lists on your plan.

Website: useagentdata.com · Docs: useagentdata.com/docs/mcp

Connect

The server is hosted at https://mcp.useagentdata.com/mcp and needs an AgentData account.

Claude (claude.ai, Desktop, mobile): Settings, Connectors, Add custom connector, paste the URL, then Connect. A page on useagentdata.com opens: sign in, or paste your API key.
ChatGPT: add AgentData from the plugin directory, then Connect.

Claude Code: or, with your key and no sign-in step:

bash

claude mcp add --transport http agentdata https://mcp.useagentdata.com/mcp --header "Authorization: Bearer YOUR_API_KEY"

claude mcp add --transport http agentdata https://mcp.useagentdata.com/mcp --header "Authorization: Bearer YOUR_API_KEY"

Cursor and other clients: the URL with an Authorization: Bearer YOUR_API_KEY header.
Local (stdio) clients:
bash
```
npx agentdata-mcp-server --api-key YOUR_API_KEY
```
```
npx agentdata-mcp-server --api-key YOUR_API_KEY
```
The package is a small bridge: each message goes to the hosted server with your key.

Your API key is in your account settings at useagentdata.com/app/settings#api. Generating a new key disconnects anything that uses the old one. Apps you connected by signing in are listed under Connected apps on the same page.

Tools

Tool	What it does
`find_technologies`	Find a technology by name or category: its exact name, category, how many companies use it, whether it is on your lists
`get_customer_list`	The companies using a technology, newest first, with how and when it was found and company details. Every company for the technologies on your lists, with filters; the first companies for any other
`get_new_customers`	Companies that recently started using a technology (7, 30 or 90 days), or across your lists
`lookup_company`	One company by domain: what it does and every technology found on it, grouped by category; with a plan, company contacts
`add_to_lists`	Add a technology to your lists, which unlocks its full customer list
`download_list`	Start a CSV download of a list on your lists (previews the size first)
`check_usage`	Your plan, lists, download records left and daily limits

Plans, lists and limits are the same as on the website: see useagentdata.com/pricing. Only downloads use records; browsing a list counts against the daily browsing limit.

Development

bash

npm installnpm run buildnpm run e2e        # the HTTP server and the stdio bridge against a local mock of the website

npm installnpm run buildnpm run e2e        # the HTTP server and the stdio bridge against a local mock of the website

The hosted server needs MCP_V3_SECRET (the same value as on the website's hosting) and reads the website at https://useagentdata.com; AGENTDATA_API_URL, AGENTDATA_ISSUER and MCP_RESOURCE override the addresses for tests.

Tools

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.

85% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
