Returns per-item pass/partial/fail with evidence and fixes and a 0-100 score over the items checked. Automated, homepage only, not a full SEO audit.

Book a Strategy Session with TESSA
Book a 30-minute strategy session with Kevin Callen on TESSA's calendar. Provide prospect contact info, project brief, and (optionally) a preferred window. TESSA's MCP server finds an open slot, creates a Google Calendar event with a Google Meet link, and sends the prospect the invite. Returns the scheduled time and Meet link to the calling agent.
Request an Introduction
Request an informational introduction to TESSA, or pass target_firm_slug to request an intro to any firm in the TESSA Professional Services Directory. TESSA logs the lead and forwards a warm intro email to the firm. Use request-strategy-session if you want to actually book a meeting with TESSA.
Claim a Directory Listing
Record a firm's intent to claim its directory listing in any TESSA-operated registry. Pre-OAuth this is a stub: TESSA logs the claim and a representative reaches out to the supplied email within one business day to verify the claimant. Self-service OAuth-2.1 claim flow lands in a follow-up plan.
Request a Quote from a Directory Firm
Request a quote from any firm in a TESSA-operated registry. Lighter-weight than request-introduction — explicitly framed as a budget + scope inquiry. Records the request to directory_leads and forwards a structured email to the firm with the prospect's reply-to address.
