Available components
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. How we score →
Endpoint Security94
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation is enforced on tool calls, advertised via RFC 9728 protected-resource metadata. Discovery is public, which costs nothing: no tool can be invoked without a token. View diagnostics → Pass
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
- The authorisation server offers only Dynamic Client Registration (RFC 7591), which MCP 2026-07-28 deprecated in favour of Client ID Metadata Documents. View diagnostics → Partial
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability83
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 773 tokens (~128/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
- Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (83% of tools); any adoption earns full credit.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

No change was recorded against any check on this day. Stability & Change Management went from 13 to 17. That category is still filling its 30-day observation window: 4 days of observed history at the previous scan, 5 at this one. The score rises as the window fills, whether or not the server changes.

compare_screening_runs Compare screening runs ~138
Compare two completed screens by their screeningId and see what changed. Costs zero credits. Two runs of the same address show why the reputation score moved. Two different addresses show a side by side. Returns each run score, band, and confidence, a reason level diff, and the score change broken into its drivers. Small differences between runs of one address can be normal variation rather than a data change.
| Name | Type | Req | Description |
|---|---|---|---|
| runIdA | string | yes | First screeningId (rsr_...). Must be a completed screen you own. |
| runIdB | string | yes | Second screeningId (rsr_...). Must be a completed screen you own. |
| Name | Type | Req | Description |
|---|---|---|---|
| compositionDiff | array | yes | Which score drivers differ between the runs |
| mode | string | yes | temporal_delta when both runs are the same address, else side_by_side |
| reasonDiff | object | yes | What changed between the two runs at the reason level |
| runA | object | yes | – |
| runB | – | yes | – |
| scoreDelta | number | yes | runA score minus runB score |
No examples provided.
get_address_screening_history Get address screening history ~136
Retrieve the authenticated user's prior screening runs for a specific Ethereum address, each with the same detail as screen_address: reputation score, band, confidence, sanctioned flag, and the top evidence signals. Use it to recall context for an already-screened address. Costs zero credits, unlike screen_address which always runs a fresh screen. For runs across all your addresses, use get_screening_history.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | Ethereum address (0x...) or .eth ENS name to look up historic screenings for |
| limit | integer | – | Number of past runs to return (1-50, default 5, newest first) |
| Name | Type | Req | Description |
|---|---|---|---|
| items | array | yes | Recent screening runs, newest first, each with the same detail as screen_address |
No examples provided.
get_credit_balance Get credit balance ~64
Returns the authenticated user's current credit balance as a whole number of credits. One credit screens one address: screen_address costs 1 credit, while this call and the history, narrative, and compare tools cost zero. Check it before screen_address to confirm a screen can be afforded.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_screening_history Get screening history ~114
Returns the authenticated user's most recent screening runs across all addresses, newest first, each with the same detail as screen_address: score, band, confidence, sanctioned flag, and the top evidence signals. Returns up to `limit` runs (default 20) with no cursor paging, so raise `limit` to reach older runs. Costs zero credits. For the history of one specific address, use get_address_screening_history instead.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | integer | – | Number of results (1-100, default 20) |
| Name | Type | Req | Description |
|---|---|---|---|
| items | array | yes | Recent screening runs, newest first, each with the same detail as screen_address |
No examples provided.
get_screening_narrative Get screening narrative ~103
Retrieve the enhanced Probity review for a completed screen by its screeningId. Costs zero credits. Returns the narrative and the key concerns it raises. It is generated in the background after screen_address returns, so it may briefly be pending. Retry shortly if so.
| Name | Type | Req | Description |
|---|---|---|---|
| screeningId | string | yes | The rsr_... id returned by screen_address. Must reference a completed screen; the narrative can be pending for a few seconds right after the screen returns. |
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | The screened address |
| concerns | array | yes | Key concerns raised by the review |
| narrative | string | yes | The enhanced review text |
| reportUrl | string | yes | Link to the full report on the Probity dashboard |
| screeningId | string | yes | The screen this review belongs to |
No examples provided.
screen_address Screen address ~167
Screen an Ethereum address or `.eth` ENS name for on-chain reputation risk. Costs 1 credit. Returns a signed reputation score (-100 to +100), a risk band, a confidence level, a sanctioned flag, the top evidence factors, a screeningId, and a link to the full report. The enhanced review is generated in the background. Fetch it with get_screening_narrative(screeningId). Use the score, band, and sanctioned flag to gate pre-trade or payout flows.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | Ethereum address (0x...) or `.eth` ENS name (e.g. vitalik.eth) to screen. ENS names resolve to their current mainnet address and must resolve or the call errors. Addresses are case-insensitive and ne… |
