In January 2026, JieGou had 31 OAuth-based integrations across 8 categories. All of them ran through a single auth provider, all of them were read-heavy, and the catalog was hand-curated.
Today: 224 MCP servers across 16 categories, exposing 1,200+ tools. Three auth types. A community submission pipeline. And connection infrastructure that handles multi-agent workflows at scale.
Here’s how we got there and what the marketplace looks like now.
Why MCP over traditional connectors
Zapier has 7,000 connectors. JieGou has 224 MCP servers. The difference: our integrations were built for AI from day one — they don’t just move data, they take action.
Traditional integration platforms were designed for data transfer between systems. MCP servers are designed for tool use — they expose typed functions that AI models can discover, reason about, and invoke as part of a multi-step plan.
Four properties make MCP fundamentally different:
AI-native. MCP servers expose tools with typed inputs, structured outputs, and natural-language descriptions. AI models can read a tool’s schema and understand what it does without custom glue code.
Open standard. MCP is not a proprietary protocol. No vendor lock-in, no per-connector licensing fees. Any MCP client can talk to any MCP server.
Action-oriented. Traditional connectors are often read-only or limited to CRUD. MCP tools perform complex actions — running a dbt model, triaging a PagerDuty incident, merging a GitHub pull request.
Composable. In a multi-agent workflow, one agent can use a Salesforce tool to pull deal context, pass it to another agent that drafts a proposal in Google Docs, and a third agent that sends it via Gmail. MCP tools compose naturally because they share the same protocol.

The biggest categories — Productivity and Finance — each have 22 servers. The smallest, AI/ML, has 8 and is growing fastest.
Three auth types
The original 31 integrations were all OAuth. That worked for consumer SaaS but locked out databases, open APIs, and self-hosted tools. The marketplace now supports three authentication modes:
OAuth — Managed connection flow. Click “Connect,” authorize in a popup, done. Used by services like Salesforce, HubSpot, Slack, and Gmail. JieGou handles token refresh and scope management.
API Key — You provide your own key. An instructions modal walks you through generating a key in the target service and pasting it into JieGou. Used by services like Stripe, Snowflake, PagerDuty, and Sentry.
None — Open servers that need no credentials. Brave Search, Puppeteer, and other tools that either don’t require auth or run locally. Direct install with one click.
This three-tier model lets the marketplace include everything from enterprise SaaS with complex OAuth flows to open-source tools with no auth at all.
How the marketplace works
The marketplace is a searchable grid. At the top, 16 category filter pills let you narrow by domain. A featured carousel highlights popular servers — anything with a popularity score of 90 or above gets surfaced here (GitHub, Slack, Notion, Salesforce, Stripe, and others).
Each server card shows:
- Server name and author
- Short description
- Tool count (e.g., “15 tools”)
- Popularity bar (0–100 scale)
- Category and auth-type tags
The install flow depends on auth type. OAuth servers open an authorization popup. API Key servers show an instructions modal with step-by-step key generation guidance. No-auth servers install immediately.
Once installed, servers show a green checkmark on their card. Connected servers are pinned to the top of the grid for quick access.
Community features
Server submission
Anyone can submit an MCP server to the marketplace. The submission form collects the server name, description, repository URL, auth type, and category. Submissions enter a review pipeline where we validate security, test tool reliability, and verify the catalog metadata before promotion to the public marketplace.
Voting board
Not every integration can be built at once. The voting board surfaces the most-requested servers so the community can influence the roadmap. Right now, 8 enterprise servers top the list: Workday, ServiceNow (additional tools), Adobe, Zuora, and others. Votes translate directly into build priority.
Community Builder badge
Contributors whose servers are accepted into the marketplace earn a Community Builder badge. The badge comes with recognition in the marketplace, priority support, and monthly updates on marketplace growth and upcoming features.
MCP Server Generator
Scaling from 31 to 224 servers required tooling. Building each server by hand would have taken months. Instead, we built an internal MCP Server Generator that scaffolds a complete server from an OpenAPI spec — or even just a service name.
Given an input, the generator produces:
index.ts— server entry point and MCP registrationtools.ts— tool definitions with typed inputs and outputsauth.ts— authentication handler for the appropriate auth typetypes.ts— TypeScript type definitions- Catalog entry with metadata, category, and tags
READMEwith usage documentation
The generator caps at 15 tools per server to keep tool lists manageable for AI models. Category-specific templates handle common patterns — CRUD operations for CRM servers, query tools for data servers, notification tools for communication servers.
This is how the team went from 50 servers in January to 105 in early February to 224 today.
Connection infrastructure
Running 224 servers across thousands of user accounts requires connection infrastructure that doesn’t fall over.
LRU connection pool. Each account maintains up to 20 concurrent MCP connections using a least-recently-used eviction policy. Connections idle for more than 60 seconds are closed automatically, freeing resources for active servers.
Per-account tool ACLs. Admins control which tools are available to which users. Three modes: allow_all (every tool available), whitelist (only specified tools), and blacklist (all except specified tools). ACLs are enforced server-side before tool calls reach the MCP server.
Integration usage analytics. The platform tracks which tools recipes actually invoke, how often, and with what success rates. This data drives marketplace ranking (the popularity score), helps identify unreliable servers, and shows admins which integrations their teams depend on.
Growth timeline
| Month | MCP servers | Notes |
|---|---|---|
| January 2026 | 50 | Expanded from 31 OAuth-only to 50 with API Key support |
| February 2026 | 105 | Community submissions, MCP Server Generator v1 |
| Today | 224 | 16 categories, 1,200+ tools |
| Q4 2026 (target) | 300+ | Focus on enterprise ERP, HRIS, and vertical SaaS |
The next wave of growth is enterprise-focused. SAP, Oracle, and Workday integrations are getting deeper tool coverage. Vertical SaaS categories — healthcare, legal, real estate — are on the roadmap for later this year.
Availability
MCP integrations are available on all plans — Free, Pro, Team, and Enterprise. The number of concurrent connections and available auth types scale with your plan, but every account gets access to the full marketplace catalog.
