Discovery

An A2A client finds this agent by fetching the well-known path on the provider's own host. That is what makes an agent card different from every other agent artifact in this catalog: it is provider-published by construction — it cannot be derived, generated, or reconstructed on a provider's behalf.

Book a Strategy Session with TESSA request-strategy-session

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-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 claim-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-quote

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.
