## Findings

- **warn** Annotations that disagree with the tool in `quote_bridge_refund` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "quote_bridge_refund" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "quote_bridge_refund" says "refund": a word that usually means money moves, which cannot be taken back.
```

- **warn** Annotations that disagree with the tool in `simulate_scenario` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "simulate_scenario" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The description's first verb is "run": a word for a change.
```


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `quote_bridge_refund`

- The name "quote_bridge_refund" says "refund": a word that usually means money moves, which cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Modeled premium estimate for cross-chain bridge execution failure against a modeled SLA expectation. Returns a modeled premium and conditions — not a live cover, refund, or premium-acceptance offer.
```

## Changes things (7)

Creates or changes something that can be changed back. Claude Code: ask.

### `check_swap`

- The description's first verb is "call": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
CALL THIS BEFORE SIGNING AN ONCHAIN SWAP. Read-only pre-sign evidence check: given notional, chain, and an optional route and token, it returns a modeled route-quality grade, price-impact / slippage band, modeled MEV/execution exposure where observable, and a token registry read (recognized vs unverified), composed into a clear / caution / unsupported verdict with machine-readable reasons and caveats. Point-in-time decision support: it does not execute, route funds, sign, or promise an outcome — the agent still decides. Recognition is not safety, sellability, redemption, rights, liquidity, or investment-quality verification; unverified tokens, unknown order flow, and uncalibrated sequencer ordering downgrade the verdict rather than reading as safe. Relay the verdict, reasons, and caveats verbatim.
```

### `quote_lrt_slashing`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Modeled premium estimate for slashing risk on a liquid-restaking-token (LRT) position given its AVS exposure. Returns a modeled premium and slashing bounds — not a live cover offer.
```

### `quote_mev_cover`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Modeled premium estimate for MEV-sandwich exposure on a swap. Returns a modeled premium (bps + USD), expected/CVaR loss, and conditions. Point-in-time decision support before routing a trade — not a live cover, insurance, or premium-acceptance offer.
```

### `record_execution`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Persist 1-100 already-built execution_record.v1 documents as immutable, personal-account post-trade evidence. Requires a stable idempotency_key; an exact replay returns the original result and reuse with different content fails closed. Pro tier, owner-scoped, and bounded by the MCP transport byte limit. This tool never accepts calldata, signing material, routes funds, executes a transaction, applies reviewer overrides, or exposes another tenant. Invalid rows are recorded only as redacted rejection reasons and are never echoed.
```

### `review_execution`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Review one stored execution_record.v1 by record_id. Authenticated and personal-account owner-scoped: another account’s id is indistinguishable from a missing id. Returns the deterministic review_execution.v1 evidence coverage, exceptions, unavailable-evidence register, caveats, and canonical hash. Read-only retrospective decision support only: it does not query arbitrary public transactions, accept reviewer overrides, certify best execution or compliance, give advice, or expose admin actions.
```

### `review_public_transaction`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
DEV-ONLY CONTRACT DISCOVERY; DISABLED AGAINST PRODUCTION. On an explicitly enabled non-production server, review one arbitrary public Ethereum transaction by transaction hash. This is separate from review_execution: it does not read an owner-scoped stored execution_record.v1 and never exposes tenant, reviewer, override, or administrative fields. Returns the deterministic tenant-free public_transaction_review.v1 coverage register, conclusions, explicit gap register, source provenance, caveats, and canonical hash. Receipt, block, index, and gas facts are measured; gas cost and point-in-time confirmation depth are calculated. Venue is unavailable in this endpoint until a server-owned verified registry adapter exists. Route, amounts, protocol fee, arrival price, feasible-route benchmark, dropped status, and historical reorg remain unavailable unless the public contract can support them. Read-only retrospective decision support only; it does not certify best execution or compliance and does not give advice.
```

### `simulate_scenario`

- The description's first verb is "run": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Run a what-if Monte Carlo: model expected premium vs expected refund/loss over a horizon, given assumptions about sandwich frequency, average loss, and deductible. Returns a narrative + distribution.
```

## Only reads (3)

Looks things up and changes nothing. Claude Code: allow.

### `get_detector_manifest`

- The name "get_detector_manifest" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch the latest public MEV-detector run manifest: the detector version hash and the eligible pool/token universe it was committed to. Use to verify what the detector covers.
```

### `get_preflight_record`

- The name "get_preflight_record" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Retrieve the durable evidence record a prior check_swap call persisted — the "record" leg of plan → preflight → execute → record. Fetch one record by the record_id that check_swap returned. Owner-scoped: the configured key only ever sees records belonging to its own account. The record embeds the evaluated check_swap response payload (including its evidence_bundle_id, before the additive record_id / record_output_hash linkage fields) plus a canonical-JSON SHA-256 integrity hash (record_id and recorded_at excluded) so the evidence can be re-verified offline, and includes the stored evidence bundle. Read-only evidence: record creation rejects known execution-material keys (calldata, transaction payloads, signing material) and drops identity-shaped labels from the actor context.
```

### `whoami`

- The name "whoami" says "whoami": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Confirm the configured API key works and report which plan tier it carries. Returns the owning account email and tier.
```
