MCP Marketplace (December 2025)
Single-purpose MCP tool servers — Slack, Postgres, Stripe, Linear, Salesforce — that any agent can call. Install in minutes, pay per call.
An MCP marketplace lists Model Context Protocol servers — single-purpose tool surfaces that any agent can call. The MCP standard turned every internal tool into a callable building block, and the marketplace turned those building blocks into installable units.
The Swfte MCP marketplace covers the surfaces buyers actually wire up: Slack, Postgres, MySQL, Stripe, Linear, Salesforce, GitHub, Notion, HubSpot, Snowflake, Google Workspace, Microsoft 365. Pricing is per-call, usually pennies. Each MCP server publishes a typed tool catalogue, scopes, and rate limits so you can wire it into existing agents in minutes.
Why buy from a mcp marketplace
- Skip months of glue code — drop in an MCP server and any agent can call it.
- Per-call pricing means trivial proofs-of-concept and cheap scale.
- Pre-audited scope and permission models, OAuth flows ready to ship.
- Versioned tool catalogues — no breaking changes to your agent without notice.
- Composable with workflow-marketplace pipelines and avatar agents alike.

FAQ
What is an MCP marketplace?
A catalogue of Model Context Protocol servers that expose internal tools (Slack, Stripe, Postgres, Salesforce) as callable surfaces for AI agents. Install one and your agents can use that tool with no glue code.
Why use an MCP server instead of writing tool calls directly?
MCP servers package the auth, scoping, rate-limiting, and typed catalogue — the boring parts of tool integration — and version them under a contract. Your agent code stays portable; swap MCP servers without rewriting tool wrappers.
How does MCP pricing work?
Almost always per-call, usually $0.001-$0.005. Some listings include a free tier for development. Total cost for a meaningful agent rarely exceeds a few dollars per active user per month.
Can I write my own MCP server and list it?
Yes. The MCP marketplace accepts third-party listings that pass the audit (typed catalogue, scope model, drift contract, sandbox-on-data). Many enterprise teams ship internal MCP servers and list them privately for their own agents.
