## Quality 85/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### 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: 86 (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: search_compounds (destructiveHint, idempotentHint); get_compound (destructiveHint, idempotentHint); where_is_it_made (destructiveHint, idempotentHint); …
- pass `tools.token_cost`: about 1,011 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: 2 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

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

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

- tools: 6, about 1,011 tokens to load them all
- tool set hash: 8ad2e2cae8e4919b0585627ff366a194
- tools last changed: 2026-10-29T15:53:32.471Z
- badge: [![protogrid quality](https://protogrid.dev/badge/com.sharpsyn/public.svg)](https://protogrid.dev/servers/com.sharpsyn/public)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-29 `value_chain` added
  - What a compound is made from (direction 'up', its precursors) or what it is used to make ('down', derived products), following main industrial routes for `depth` steps (1 to 4). Each entry has its name, CAS and page URL where SharpSyn has one.
- 2026-10-29 `where_is_it_made` added
  - Where a compound is produced, from the SharpSyn Chemical World Map: the known production sites (name, operator, country, coordinates), how they spread over countries (share per country, single-site warning), the confidence and source of each entry, and the page and map links to cite. Site products from public research are estimates; operators marked 'unclaimed' have profiles built from public sources, not managed by them. Each site has the status of the line (operating, closure_announced, idle, planned, under_construction, closed, with dates), the operator of that line and its capacity (t/a with basis, year and reference substance). By default only lines producing now; include_inactive adds the rest. Shares per country by site count and by capacity, and the coverage: how many sites are known, how many with capacity, and what share of world production that is where the world production is on record.

## Tools (6)

- `get_compound`: Everything SharpSyn publishes about one compound, given its CAS number,
    InChIKey or name: identifiers, structure (SMILES, InChI), number of verified
    suppliers with regions, grades and lead times, price range per kg with its
    confidence label and data date, the cradle-to-gate carbon footprint with
    tier, source and uncertainty, and the page URL to cite. If the compound has
    no public page, says so and gives a link where the user can still ask
    suppliers for it.
- `list_suppliers`: Suppliers listed publicly on SharpSyn (companies that asked to be listed),
    optionally only those in one country or offering one compound (CAS, InChIKey
    or name). Returns company name, country, website, number of public listings
    and the profile URL.
- `request_quote_link`: A link the user opens to ask SharpSyn's suppliers for a quote on a
    compound (CAS number, InChIKey or name). Nothing is sent by calling this:
    the user fills in quantities and sends the request themselves.
- `search_compounds`: Find compounds on SharpSyn by name, synonym, CAS number, InChIKey or
    molecular formula. Returns name, CAS, InChIKey, page URL and a summary of
    suppliers, price and carbon footprint for each match, best matches first.
- `value_chain`: What a compound is made from (direction 'up', its precursors) or what
    it is used to make ('down', derived products), following main industrial
    routes for `depth` steps (1 to 4). Each entry has its name, CAS and page
    URL where SharpSyn has one.
- `where_is_it_made`: Where a compound is produced, from the SharpSyn Chemical World Map:
    the known production sites (name, operator, country, coordinates), how
    they spread over countries (share per country, single-site warning), the
    confidence and source of each entry, and the page and map links to cite.
    Site products from public research are estimates; operators marked
    'unclaimed' have profiles built from public sources, not managed by them.
    Each site has the status of the line (operating, closure_announced, idle,
    planned, under_construction, closed, with dates), the operator of that
    line and its capacity (t/a with basis, year and reference substance).
    By default only lines producing now; include_inactive adds the rest.
    Shares per country by site count and by capacity, and the coverage: how
    many sites are known, how many with capacity, and what share of world
    production that is where the world production is on record.
