# SigParser documentation

Research date: 2026-09-07

Documentation coverage: not-retrieved.

Reference index, not a mirror of complete vendor documentation. Retrieved pages do not prove the MCP works.

## What it does

A relationship-intelligence and contact-capture product that scans connected mailboxes, calendars and address books, parses email signatures, and turns the result into contact and company records with who-knows-who relationship scores, exportable to a CRM, a spreadsheet or a data warehouse.

## Access and connection

MCP support: official

Access requirements: enterprise-leaning - the vendor's pricing page lists "Access API Endpoints" only under the Enterprise tier, prices that tier at $499 per month billed annually, and gives it a "Schedule a Demo" button, while the three tiers below it (Individual $19, Team $49, Professional $299) carry "Start Free Trial". A price is published, but the only tier that carries the API is the one routed through sales.

Authentication: unknown. The endpoint answers HTTP 401 to an unauthenticated MCP initialize but no first-party page documents the scheme; SigParser's REST API, served from the same ipaas.sigparser.com host, uses an API key.
