## 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**: 66/100
  - 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 6 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.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 73/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 827 tokens (~137/item across 6 items; 6 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**: 96/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 89% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-03 (score 70, +1)

No change was recorded against any check on this day. Stability & Change Management went from 23 to 27. That category is still filling its 30-day observation window: 7 days of observed history at the previous scan, 8 at this one. The score rises as the window fills, whether or not the server changes.

## MCP tools (6)

### `trace_create_workspace` (~148 tokens)

Create an isolated, disposable (ephemeral) vector-search workspace - your own sandboxed index/namespace for semantic retrieval and RAG. Prepays container time via x402 micropayment (USDC on Base, EIP-3009); no account, no signup. Call without x_payment to get the price + payment terms; with a signed x_payment it returns a one-time capability_token for the other tools.

Input parameters:

- `spend_limit_usd` (number): Optional cap on total spend incl. extensions
- `ttl_minutes` (integer): Container minutes to prepay (default 15)
- `x_payment` (string): Base64 signed x402 payment payload (EIP-3009)

### `trace_search` (~154 tokens)

Semantic vector search / similarity retrieval (nearest-neighbor, embedding-based) over your private disposable index - the core RAG retrieval call. Supports natural-language text queries, cross-modal text->image, and reverse-image search (image_b64). Returns ranked passages/hits with locators. Provide query OR image_b64.

Input parameters:

- `families` (array): visual | text_semantic | raw
- `image_b64` (string): Base64 image for reverse-image search
- `k` (integer): Number of results (default 8)
- `query` (string): Natural-language query
- `workspace_id` (string, required): Workspace id from trace_create_workspace
- `workspace_token` (string, required): Capability token from trace_create_workspace

### `trace_ingest_batch` (~99 tokens)

Ingest and index documents, passages or text chunks into your workspace to build the searchable vector/embedding index for semantic search and RAG retrieval. Each document: {name, text OR content_b64, mime?}; supports text and binary (base64) content.

Input parameters:

- `documents` (array, required)
- `workspace_id` (string, required): Workspace id from trace_create_workspace
- `workspace_token` (string, required): Capability token from trace_create_workspace

### `trace_get_passage` (~67 tokens)

Retrieve a single stored passage/document/item (content and metadata) from your workspace vector index by item id.

Input parameters:

- `item_id` (string, required)
- `workspace_id` (string, required): Workspace id from trace_create_workspace
- `workspace_token` (string, required): Capability token from trace_create_workspace

### `trace_get_usage` (~66 tokens)

Get workspace usage and billing status for your disposable vector-search workspace: prepaid time/TTL remaining, total spend, ingest/search counts, and state.

Input parameters:

- `workspace_id` (string, required): Workspace id from trace_create_workspace
- `workspace_token` (string, required): Capability token from trace_create_workspace

### `trace_dispose_workspace` (~67 tokens)

Dispose and permanently delete the workspace and its in-memory vector index/data (zero data retention); returns a cryptographically signed disposal receipt confirming the wipe.

Input parameters:

- `workspace_id` (string, required): Workspace id from trace_create_workspace
- `workspace_token` (string, required): Capability token from trace_create_workspace
