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.
