## Quality 88/100 (new)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 88 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 6 of 6 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: get_quotes (destructiveHint, idempotentHint, openWorldHint); list_providers (destructiveHint, idempotentHint, openWorldHint); create_swap (readOnlyHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,690 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump
- pass `tools.hidden_text`: no hidden text in tool names, descriptions, schemas or annotations

### stability: n/a (weight 15)

- n/a `stability.changes`, `stability.rug_pull`, `stability.new_links`: tool history recorded for 0 of the 7 days needed

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 6, about 1,690 tokens to load them all
- tool set hash: cfca834b6d32115ac8b9aae46bb9fe16
- badge: [![protogrid quality](https://protogrid.dev/badge/com.swaplume/mcp.svg)](https://protogrid.dev/servers/com.swaplume/mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (6)

- `create_swap`: Create the swap and get the deposit address. No funds move here: the user then sends amount_from of
from_asset to deposit_address (with deposit_extra_id as the memo, when present), as instructions says.
Follow it with get_swap.
- `get_quotes`: Compare every exchange's offer for a swap, best first.

In each quote, amount_to is what the user receives after all fees. With amount_to given instead of amount,
quotes are sorted by amount_from, what the user sends. errors lists the exchanges that can't, and why (with
their min/max when the amount is out of range); with no quote at all, limits has the widest min/max: suggest
an amount inside it. savings_pct: how much more the best quote gives than the worst. Ask again after
refresh_after seconds, not sooner.
- `get_swap`: A swap's live status: waiting (for the deposit), confirming, exchanging, sending, finished, failed,
refunding, refunded, expired, verifying (held for an ID check), action_required or unknown. instructions is
the next step, for the user. Read it again after poll_after seconds, not sooner (each read asks the
exchange), until is_final.
- `list_currencies`: Find assets and their networks. Each id ('ticker:network') works as from_asset or to_asset. contract: the
token's address; extra_id_name: the asset uses a memo/tag.
- `list_providers`: The exchanges compared, with what each asks of a swap (email_required, refund_address_required...), kyc,
ip_shared, ip_kept and notice.
- `validate_address`: Check a payout or refund address (create_swap runs the same check). valid: true; false: show reason to the
user and ask again; null: this network's format isn't checked here. extra_id_name: the asset uses a
memo/tag.
