SigParser now connects directly to AI tools like Claude, ChatGPT, Harvey AI, Athena, and other MCP-compatible assistants through a Model Context Protocol (MCP) server. This means you can access your contact database, company records, and relationship intelligence without ever leaving your AI workspace.
This feature requires an active SigParser subscription.
What Is an MCP Server?
Model Context Protocol (MCP) is an open standard that allows AI assistants to securely connect to external data sources and tools. By connecting SigParser’s MCP server to a compatible AI tool, your assistant can access and query your SigParser data—contacts, companies, relationships, and more—in real time, as part of a natural conversation.
You can also create and update records, as well as trigger enrichment, directly from within your AI assistant.
What Data Is Available
Once connected, your AI assistant can access:
Contacts — names, email addresses, phone numbers, titles, seniority levels, location, interaction history, and relationship metrics
Companies — name, domain, industry, employee count, location, and overall relationship metrics
Relationships — the full history between any team member and any external contact, including emails sent and received, meetings held, relationship score (0–100), and interaction dates (Team subscription or higher required)
Coworkers — basic profile info on internal team members with connected mailboxes
Job Experiences — career history for contacts enriched via LinkedIn
What Can You Do With It?
The SigParser MCP server gives your AI assistant direct access to your relationship intelligence.
Common use cases:
Pre-Meeting Briefs — Get a full snapshot of a company, including key contacts, relationship strength, and recent interactions
Follow-Up Recommendations — Identify who to reconnect with based on relationship health and activity
Industry Network Analysis — Understand your team’s coverage and strength within a specific industry
Contact & Company Lookups — Quickly find contacts, companies, and relationship details using simple queries
Enrichment & Validation — Update contact data and verify email deliverability directly from your AI tool
For more details, see SigParser MCP Server: Use Cases.
Enable MCP Endpoint Permission
Access to the MCP server is controlled by a dedicated “Can Use MCP Endpoint” (mcp_use) permission.
Automatically granted to users with the Mailbox Admin role
Must be enabled for a user’s role by an admin before they can connect
Access to relationship data still requires the View All Relationships permission
The All Relationships feature is available on Team subscriptions and above.
How to Connect
If SigParser is not yet in the app store for your MCP-compatible assistant, you can configure your MCP client with the following:
Transport: HTTP (streamable)
OAuth (Recommended)
MCP clients that support OAuth 2.0 — such as Claude Desktop — handle authentication automatically. You can connect directly via the Claude marketplace without any manual configuration. The client will guide you through signing in to your SigParser account.
API Key (Manual)
For clients that don't support OAuth, generate an API key from your SigParser account settings (the key must have the all scope) and provide it in the request header:
x-api-key: your-api-key-here
Regardless of how you authenticate, your SigParser role must have the Can Use MCP Endpoint permission enabled. Contact your SigParser admin if you need access.
For more details, see SigParser MCP Server: Configuration Details.
