MCP support
The hosted MCP server at https://mcp.abm.dev/mcp exposes tools to search, source, enrich, and create B2B records and outreach. A local npx bridge proxies to the hosted server and handles OAuth 2.1 PKCE sign-in and token caching.
Configuration
Remote servers need no local install. Pick your client, then copy the config or install in one click.
https://mcp.abm.dev/mcpclaude mcp add --transport http abm https://mcp.abm.dev/mcp{"mcpServers":{"abm":{"type":"http","url":"https://mcp.abm.dev/mcp"}}}Open in Cursor{"servers":{"abm":{"type":"http","url":"https://mcp.abm.dev/mcp"}}}Open in VS Code{"mcpServers":{"abm":{"type":"http","url":"https://mcp.abm.dev/mcp"}}}{"mcpServers":{"abm":{"serverUrl":"https://mcp.abm.dev/mcp"}}}Run commands in a terminal; paste JSON into the client’s MCP config and restart. Servers that need sign-in will prompt on first connect.

abm.dev MCP server
The account-based marketing API for AI agents.
Search, Enrich, and Create across B2B people and companies — every field cited with a source and confidence score. One key, ten sources, no per-field bills.
- Hosted server:
https://mcp.abm.dev/mcp - Homepage: https://abm.dev
- For agents (machine-readable): https://abm.dev/llms.txt
What your agents can do
abm.dev is the account-based marketing API for AI agents. One key, one schema, four verbs:
- Search — find companies and people by criteria.
search_companies,search_contacts. - Source — hand it a target account, get the right buying-committee people back. Async briefs:
source,get_source. - Enrich — cited, multi-source fields on any person or company.
create_enrichment,get_enrichment_fields,get_enrichment_sources. - Create — write CRM records and stage outreach.
create_company,create_contact,create_outreach;queue_linkedin_poststages a post for human approval — it never auto-publishes.
Every value carries its source and a confidence score (0–1). A value is cited or it is not returned. No fabricated facts.
What you get
- Eighty-nine canonical fields per record — forty-three on the person, forty-six on the company.
- Forty signals on every prospect.
- Ten sources, resolved into one response — LinkedIn, Companies House, Perplexity, Tavily, Hunter, and others.
- A citation on every value —
sourceandconfidence(0–1), with the winning source that produced it.
No per-source bills. No per-field charges. No silent fallbacks.
Connect
Claude (custom connector)
- Open Settings → Connectors → Custom.
- Paste the server URL:
https://mcp.abm.dev/mcp - Complete the one-time sign-in when prompted.
Then ask, in plain language: "Find the VP of Marketing at Acme, then enrich them."
Claude Code (plugin)
One install wires both the connector and the abm.dev Agent Skill — no URL pasting:
/plugin marketplace add abm-dev-git/abm-mcp
/plugin install abm-dev@abm-dev
OAuth sign-in happens on first tool use. See claude-plugin/.
Cursor / Claude Code / Windsurf
These agents drive the REST API directly. Paste this prompt:
Read https://abm.dev/llms.txt. Request an API key, save it to
.envasABM_API_KEY, then run a test enrichment againsthttps://api.abm.dev/v1/enrichments. Report the result with its citations.
Script and terminal agents
Call the REST API directly:
curl https://api.abm.dev/v1/enrichments \
-H "x-api-key: $ABM_API_KEY" \
-H "Content-Type: application/json" \
-d '{"type":"person","input":{"email":"[email protected]"}}'
input also accepts a LinkedIn URL or a company domain.
Install (npx)
Prefer a local command over a remote URL? The @abmdev/mcp package is a thin
bridge: npx -y @abmdev/mcp launches a local STDIO MCP server that proxies to the
hosted server at https://mcp.abm.dev/mcp, handling the OAuth 2.1 PKCE sign-in
and token caching for you. It defines no tools of its own — it exposes whatever
the hosted server serves.
Add it to any MCP client that supports command/args (Claude Desktop,
Cursor, Windsurf, Claude Code, and others):
{
"mcpServers": {
"abm": {
"command": "npx",
"args": ["-y", "@abmdev/mcp"]
}
}
}
Generic config snippet (for clients that take a bare command):
{ "command": "npx", "args": ["-y", "@abmdev/mcp"] }
On first run a browser window opens for the one-time sign-in; the token is then
cached for subsequent runs. Point the bridge at a different endpoint by setting
the ABM_MCP_URL environment variable.
Either path reaches the same hosted server. Use the custom connector (remote URL) above if your client supports it directly; use npx for clients that only speak local
command/args.
Tools
Grouped by verb — every field comes back with its source and confidence (0–1). Real-time SSE streaming for agent loops; webhooks fire when batch jobs finish.
Search — search_companies, search_contacts: find accounts and people by criteria.
Source — source, get_source: give it an account, get the right people back (async brief).
Enrich — create_enrichment, get_enrichment, get_enrichment_fields, get_enrichment_sources: cited, multi-source fields on a person (from an email or LinkedIn URL) or a company (from a domain).
Create — create_company, create_contact, create_outreach, queue_linkedin_post: write CRM records and stage outreach. Staged posts wait for human approval; nothing publishes automatically.
Pricing

Comments
New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
