## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 10 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 69/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 1140 tokens (~114/item across 10 items; 10 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 67/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

### 2026-07-26 (score 57)

First indexed and scored.

## MCP tools (10)

### `get_services` (~127 tokens)

Returns TESSA's full service catalog (SEO, paid media, web/app development,
        AI agent readiness, accessibility, and more). Each service includes its live
        per-service A2A card URL (`agent_card`) and JSON-RPC endpoint (`a2a_endpoint`),
        so you can discover a service here and then talk to its dedicated A2A agent.
        Optional filters:
            category_slug: marketing | web-development | ai-experiences
            service_slug:  filter to one specific service

Input parameters:

- `category_slug`
- `service_slug`

### `get_case_studies` (~62 tokens)

Returns TESSA's portfolio of project results.

        Optional filters:
            industry:     industry name keyword (case-insensitive contains)
            service_slug: filter to studies that used a given service

Input parameters:

- `industry`
- `service_slug`

### `assess_ai_readiness` (~74 tokens)

Given a website URL, returns a 0-100 AI Agent Readiness score with
        category breakdowns (structured data, metadata quality, agent
        discoverability, AI-bot friendliness) and concrete recommendations.
        Pure deterministic check, fast, no LLM call.

Input parameters:

- `url` (string, required)

### `find_professional_services_firm` (~98 tokens)

Search the TESSA Professional Services Directory.

        industry:   segment slug ('marketing' | 'compliance')
                    or free-text keyword
        region:     city or state name (case-insensitive contains)
        capability: keyword to match against firm descriptions and service names
        limit:      max results

Input parameters:

- `capability`
- `industry`
- `limit` (integer)
- `region`

### `get_firm_profile` (~60 tokens)

Returns the full dossier for a single firm in the directory:
        description, headquarters, founded year, employee band, services,
        locations, and directory meta (publisher, claim URL, takedown URL).

Input parameters:

- `slug` (string, required)

### `get_wcag_audit` (~96 tokens)

Returns the structured offering for TESSA's WCAG 2.2 AA Accessibility
        Audit: scope, deliverables, timeline, pricing bands (hourly + engagement
        range), paired service-type slugs, and the URL of TESSA's profile in the
        TESSA Compliance Registry. Use this when a buyer agent needs TESSA's
        accessibility audit offering in structured form.

### `request_strategy_session` (~186 tokens)

Book a 30-minute strategy session with TESSA on Kevin Callen's
        calendar. Finds an open slot in the requested window (or the next
        5 business days), creates a Google Calendar event with a Google Meet
        link, and emails the prospect the invite. If no slot is available,
        captures the lead and Kevin follows up manually. TESSA-only tool —
        directory firms use request_introduction instead.

        requested_window accepts ISO 8601 ranges ('2026-04-30T13:00/2026-04-30T17:00'),
        single dates ('2026-04-30'), or English ('tomorrow', 'next week').

Input parameters:

- `project_brief`
- `prospect_email` (string, required)
- `prospect_name`
- `prospect_org`
- `requested_window`

### `request_introduction` (~151 tokens)

Request an informational introduction — to TESSA itself, or to any
        directory firm if you pass target_firm_slug. TESSA logs the lead and
        either notifies sales@tessa.tech + kevincallen@tessa.tech (TESSA
        leads) or forwards a warm intro email to the firm with TESSA Cc'd
        (directory leads). No calendar booking — use request_strategy_session
        to book a meeting with TESSA.

Input parameters:

- `project_brief`
- `prospect_email` (string, required)
- `prospect_name`
- `prospect_org`
- `requested_window`
- `target_firm_slug`

### `claim_listing` (~118 tokens)

Record a firm's intent to claim its directory listing.

        Pre-OAuth this does NOT automatically grant control of the listing.
        TESSA logs the claim and a representative reaches out via email
        within one business day to verify the claimant and switch the
        listing's verification status to 'claimed'. The full self-service
        OAuth-2.1 claim flow lands in a follow-up plan.

Input parameters:

- `claim_email` (string, required)
- `claimant_name`
- `claimant_role`
- `firm_slug` (string, required)

### `request_quote` (~168 tokens)

Request a quote from a directory firm. Lighter-weight than
        request_introduction — explicitly framed as a budget+scope inquiry.

        firm_slug:       directory slug for the target firm
        prospect_email:  caller's email for the firm's reply
        scope_summary:   one-paragraph description of the work
        budget_band:     'under_5k' | '5k_25k' | '25k_100k' | '100k_plus' |
                         'open' — or any free-text dollar figure

Input parameters:

- `budget_band`
- `firm_slug` (string, required)
- `prospect_email` (string, required)
- `prospect_name`
- `prospect_org`
- `requested_window`
- `scope_summary` (string, required)
