- LOWTool 'fetch' suggests web access but openWorldHint=falsein fetch
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tools (11)
🟢search(query, limit)
Search the user's CortexPlus memory and return ranked matches. Use this to find what the user has stored before answering from memory. Health data (`saude` tag) is only included when the user has enabled sharing it with AI assistants in CortexPlus settings.

}🟢fetch(id)
Retrieve the full content of one CortexPlus memory item by id, as returned by search. Health data (`saude` tag) is only included when the user has enabled sharing it with AI assistants in CortexPlus settings.

}🟢recall(query, limit, depth, maxChars)
Build a context block from the user's CortexPlus memory: the passages that answer a question plus their graph neighbours, already formatted as text. Prefer this over search when you intend to answer from the user's memory. Health data (`saude` tag) is only included when the user has enabled sharing it with AI assistants in CortexPlus settings.

}🔴save_context(content, platform, key, title, model, ...)

}🟡signup(email, name, client)
Create a CortexPlus account, or begin signing in to an existing one, so this conversation can use CortexPlus as the user's long-term memory and knowledge base. Ask the user for their email address, and for their name if you do not already have it, then call this tool. CortexPlus sends them a 6-digit code by email; ask the user for that code and call connect with it and the same email. Never guess or invent the email address.

}🟡connect(email, key, client)
Complete the CortexPlus connection with the 6-digit code the user received by email after signup.
