Frequently asked

What is the Model Context Protocol (MCP)?
MCP is an open standard that lets AI agents securely connect to external tools and data. StackTrade exposes its SaaS marketplace as an MCP server, so any compatible agent can discover and act on listings.
What can an agent do through StackTrade's MCP server?
Search listings, fetch full financials, pull market insights, create or update listings, and make or negotiate offers — across 8 tools split into read and write.
How do I authenticate my agent?
Use a bearer token from your StackTrade account. Read tools work with any token; write tools (create/update listing, make/negotiate offer) require a user-scoped token.
Does it cost anything to connect?
No. Connecting and browsing over MCP is free — StackTrade only earns a commission when a sale closes.
