Quote parts from your agent
SSG MFG exposes the same estimator, catalog and RFQ desk the builder uses to any AI agent. Connect Claude, ChatGPT or your own agent to the MCP server at /api/mcp, call the REST API, or use the WebMCP tools registered in the browser. No key needed to estimate.
Connect in a minute
The MCP server is remote and stateless. Add it wherever your agent reads MCP servers.

Pick a sample part and run it. This calls POST /api/v1/estimate on this site, the same endpoint and response your agent gets.
{ "template": "bracket", "params": { "width": 60, "thickness": 2 }, "process": "metal-stamping", "material": "steel-1008-crs", "quantity": 25000, "compare": true}Response
Run the request to call the live API. No key, rate limited per IP, budgetary numbers.
MCP tools
- list_processesread-only
- Every process SSG MFG sources, with volume sweet spot, lead time and typical specs. Use it to pick a process before estimating.
- list_templatesread-only
- Part families the estimator models exactly (plate, bracket, housing, shaft, bushing, drawn cup, spring, gear, seal, soft case, hex standoff, U-channel, heat sink), with parameter keys, units and valid ranges.
- search_catalogread-only
- Keyword search across the SSG MFG catalog and guides. Returns slugs to pass to get_entry.
- get_entryread-only
- Full detail for one process (design rules, specs, FAQs), material (properties, equivalents), finish (standards), industry (requirements), glossary term, or guide.
- estimate_partread-only
- Instant budgetary estimate for a custom part: unit price, tooling, price breaks, lead time, DFM issues with fixes, and cheaper alternative processes. Estimates are budgetary; firm quotes come from principals via request_quotes.
- request_quotessends
- Sends an RFQ to SSG MFG. A rep reviews it and routes it to matched manufacturers, then replies to the contact email with firm quotes. Confirm with the user before calling, and only use contact details the user gave you.
- contact_ssgsends
- Passes the user's question and contact details to an SSG MFG rep, who replies by email or phone. Use it when the user wants to talk to someone, has no part spec yet, wants a drawing reviewed, or asks about becoming a rep or principal. The user gets an email confirming it was received. Confirm with the user before calling, and only use contact details the user gave you.

WebMCP in the browser
For agents that browse: tools registered with document.modelContext on every page.
Browsers with WebMCP (Chrome's early preview and later) see five tools on ssgmfg.com: list processes, look up an entry, estimate a part, open it in the 3D builder, and request quotes. Sending an RFQ asks the user to confirm first. The tools call the same public API, so results match the builder exactly.
Questions
Do I need an API key?
Not for estimates, catalog reads or the MCP server. Requests are rate limited per IP. RFQs are free to send; a rep reviews each one. Contact us for higher limits or a partner key.
Are the prices real quotes?
They are budgetary estimates from SSG's cost models, typically within 15–35% depending on how complete the part description is. Firm quotes come from principals after a rep routes the RFQ.
What should an agent do before sending an RFQ?
Show the user the parts, quantities and estimate, and get explicit confirmation. The request_quotes tool and the WebMCP tool both expect the user's own name and email. Never invent contact details.
Can the builder open a part my agent designed?
Yes. Every estimate response includes next.open_in_builder, a /build link with the spec encoded, so the user can see the part in 3D, adjust it and send the RFQ themselves.
Building a hardware agent?
