Nothing serious here today

Today is the operative word: we check SharpSyn every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 6

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

compound
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.
compounds
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.
request
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.
suppliers
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.
value
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
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.

SharpSyn — questions

Answers built from our own checks of this server.

What can SharpSyn do?
It exposes 6 tools, read directly from the server on our last check. Among them: get_compound, list_suppliers, request_quote_link, search_compounds, value_chain, where_is_it_made. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is SharpSyn working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 280 ms. The bar chart above shows every period we have measured.
How do I connect SharpSyn?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does SharpSyn need an API key?
No. SharpSyn completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is SharpSyn?
It answers our handshake in 280 ms on average, which is faster than 51% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
