Signaliz MCP

Signaliz is a B2B data quality, enrichment, and agentic GTM platform for go-to-market teams and AI agents. The Signaliz MCP server gives MCP clients access to 60+ Signaliz API capabilities for verified lead generation, email verification, company enrichment, data-quality pipelines, Ops routines, approvals, ICPs, app actions, and workspace controls.

This repository is the public distribution manifest for Signaliz MCP. It contains registry metadata, indexable tool schemas, and setup instructions for MCP directories and clients. The production server is hosted by Signaliz; this repository does not contain the private server implementation.

Hosted Endpoint

https://api.signaliz.com/functions/v1/signaliz-mcp

Transport: Streamable HTTP

Authentication: Signaliz API key or OAuth, depending on client support.

Related MCP server: open-sales-stack

Quick Start

Create an API key in Signaliz from Settings > Developer > API Access, then connect your MCP client to:

https://api.signaliz.com/functions/v1/signaliz-mcp?api_key=YOUR_API_KEY

Clients that support headers can connect to the base endpoint and send:

Authorization: Bearer YOUR_API_KEY

Clients that support OAuth discovery can use the protected-resource metadata advertised by the server.

Local Stdio Bridge

For clients that prefer local stdio MCP servers, install the npm bridge:

claude mcp add signaliz -e SIGNALIZ_API_KEY=sk_your_key -- npx -y @signaliz/mcp-server

Claude Desktop, Cursor, Windsurf, Cline, and other stdio clients can use:

{
  "mcpServers": {
    "signaliz": {
      "command": "npx",
      "args": ["-y", "@signaliz/mcp-server"],
      "env": {
        "SIGNALIZ_API_KEY": "sk_your_key"
      }
    }
  }
}

What Signaliz Does

Signaliz exposes tools for:

  • Finding verified emails for known contacts.

  • Verifying deliverability for one email or thousands of emails.

  • Discovering buying signals such as hiring, funding, product launches, partnerships, leadership changes, expansion, acquisitions, awards, regulatory events, and earnings.

  • Finding B2B professionals, target accounts, local businesses, or outreach-ready leads.

  • Running custom AI prompts across records with structured output fields.

  • Calling external APIs through generic HTTP tools.

  • Uploading lists and running governed Signaliz systems against them.

  • Creating autonomous Ops Routines that work on a GTM goal over time.

  • Chaining routines, streaming results, emitting events, and resolving approvals.

  • Connecting apps, discovering available actions, and executing app actions through Signaliz.

  • Managing budgets, blocklists, ICPs, campaign books, and durable agent memory.

Every tool accepts output_format, which can be markdown or json. Use json when another agent, script, or workflow needs structured output.

Access Model

Signaliz plans include full API and MCP access, unlimited workspaces, unlimited integrations, audit trail and MCP analytics, BYOK OpenRouter support, and all core platform features. Plans differ by included monthly GTM credits, and additional credits can be purchased for metered provider-backed actions such as email verification, person or company discovery, company signal enrichment, monitoring, custom AI prompts, and Lead Finder.

Signaliz is not positioned as unlimited-volume or all-you-can-use data. The product is designed around accuracy, timing, governed workflows, and transparent GTM credit usage.

Capability Index

The full indexable tool schema lives in tools/tools.json. It is generated from the actual @signaliz/mcp-server@2.0.1 tools/list response so directories can index the same names, descriptions, and input schemas exposed by the npm bridge.

Registry Metadata

Safety Notes

Read-only enrichment and discovery tools do not mutate your external systems. Tools that upload data, create or run systems, connect apps, execute app actions, update blocklists, approve work, or delete routines can change Signaliz workspace resources or connected systems and should be used with your normal approval controls.
