Signaliz MCP
Signaliz is a B2B data quality and enrichment platform for go-to-market teams and AI agents. The hosted Signaliz MCP server helps agents find and verify professional emails, verify deliverability, enrich companies with buying signals, clean and govern lists, and run data-quality pipelines before records move into CRMs, sequencers, or other systems of record.
This repository is the public distribution manifest for the hosted Signaliz MCP server. It contains metadata, tool schemas, and setup instructions for MCP registries and clients. The production server is hosted by Signaliz.
Hosted Endpoint
https://api.signaliz.com/functions/v1/signaliz-mcp
Transport: Streamable HTTP
Authentication: Signaliz API key or OAuth, depending on client support.
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.
What Signaliz Does
Signaliz exposes tools for:
- Finding and verifying professional email addresses from a person's name and company domain.
- Verifying existing email addresses at batch scale.
- Enriching companies with structured business signals such as hiring, funding, product launches, partnerships, leadership changes, expansion, acquisitions, awards, regulatory events, and earnings.
- Uploading CSV or JSON lists for processing.
- Building and running governed data pipelines with validation, deduplication, blocklists, data contracts, dead-letter handling, and output sinks.
- Checking async job and pipeline status.

Safety Notes
Signaliz is designed as a data-quality checkpoint for agent workflows. Email verification and company enrichment tools are read-only against the user's systems of record. Pipeline, upload, output, and blocklist tools can create or update Signaliz workspace resources and should be used with the client's normal consent controls.
