MCP tools in AI chat: connect GitHub, Notion, and more
Models without tools only talk. MCP lets chat call the systems you already run. Without leaving zy.ai.
MCP tools in AI chat close the gap between “good answer” and “done in my stack.” Model Context Protocol (MCP) lets zy.ai attach remote tools. GitHub, Notion, Linear, Slack, scrapers, and custom HTTPS endpoints. So the model can act with context you already trust.
What MCP is (short)
MCP is a standard way for an AI client to discover and call tools exposed by a server. On zy.ai you connect remote Streamable HTTPS MCP servers (Cloudflare Workers cannot run local stdio processes). OAuth and bearer tokens are supported depending on the server.
What you can connect
- GitHub repositories and issues
- Notion pages and notes
- Linear, Asana, monday, Atlassian
- Slack workspace tools
- Search and scrape utilities (where configured)
- Custom MCP endpoints you host
Catalog and setup live in the app MCP sidebar after sign-in. Docs overview: /docs.
Limits by plan
- Free / Pro: up to 3 MCP servers
- Ultra: up to 10 servers
- Only connect servers you trust; tools can read or write depending on the server’s design
MCP is available on member accounts (Free, Pro, Ultra). Frontier model quality still follows the Free vs Pro ladder. See when to upgrade.
A sane workflow
- Sign in and open the MCP sidebar.
- Add a remote HTTPS MCP URL (or a catalog server).
- Authorize OAuth or paste a bearer token if required.
- Chat as usual; the model can call connected tools when useful.
- Switch models mid-thread if one model uses tools better for the job. Multi-model still applies.

Security basics
Treat MCP like API keys. Prefer least privilege, revoke unused servers, and never paste secrets into the chat when a server already holds them.
zy.ai does not replace your vendor’s security model; it routes tool calls to endpoints you configured.
When MCP is overkill
If you only need drafts and code snippets, stay simple: free models, no tools. Add MCP when the bottleneck is “copy from GitHub / Notion / Linear into the prompt.” That is the same philosophy as free-first multi-model access. Tools when the job earns them.
Business research agents (SEO, company intel, leads) on Ultra are separate product surfaces: /business and business search agents.
