Use MCP servers in nanobot with Toolport
Toolport is a free, open source local MCP gateway. Add your servers to Toolport once, flip the nanobot toggle, and nanobot gets all of them through a single gateway entry. Toolport picks a full tool list or search for each client, and you can change it in Clients.
Setup
- Download Toolport for Windows, macOS or Linux, and add your MCP servers to it (or import the ones your other AI agents already have; secrets go to your OS keychain).
- Open the Clients tab and toggle nanobot on. Toolport writes its gateway entry into nanobot's config, next to anything already there.
- Restart or reload nanobot. Your full server set is available through Toolport, and any server you add later shows up without touching nanobot again.
Where nanobot keeps its MCP config
nanobot MCP config
All platforms ~/.nanobot/config.json
Strict JSON, servers under tools.mcpServers.
Good to know
- nanobot registers every MCP tool up front and doesn't re-list, so Toolport keeps it on search to save context.
- This is HKUDS/nanobot, not the unrelated Obot nanobot. Restart the session to load changes.
Why a gateway instead of nanobot's own server list?
- One setup, every agent. The same servers work in nanobot and every other AI agent on your machine; add a server once and they all get it.
- Secrets in the OS keychain. API keys are injected at runtime and never sit in nanobot's config file.
- Watched by default. Rug-pull and tool-poisoning detection on every tool, plus per-tool governance and a destructive-tool kill switch. How the security works.
Free on this machine. Pro puts it on every machine. Team gives it to everyone.
