## Quality 72/100 (needs work)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth

- pass `tools.token_cost`: about 1,718 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 25 (weight 15)

- warn `stability.changes`: 15 tool changes in 30 days
- fail `stability.rug_pull`: 1 tools kept their name but changed most of their description in 30 days; review before trusting them

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 11, about 1,718 tokens to load them all
- tool set hash: 779991cdb4a4a66e771cd9158d322d3c

- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-14 `connect` changed (description, inputSchema)
  - before: Complete the CortexPlus connection with the short authentication key the user received by email after signup. Ask the user to paste the key, then call this tool; never guess or invent the key. The response includes an API key that the AI platform should save in its CortexPlus connector configuration.
  - after: Complete the CortexPlus connection with the 6-digit code the user received by email after signup. Ask the user for the code, then call this tool with the same email used in signup; never guess or invent the code. The response includes an API key that the AI platform should save in its CortexPlus connector configuration.
- 2026-10-14 `signup` changed (description)
  - before: 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 short authentication key by email; ask the user for that key and call connect with it. Never guess or invent the email address.
  - after: 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.

- 2026-10-04 `recall` changed (description, annotations)
  - before: 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.
  - after: 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.
- 2026-10-04 `fetch` changed (description, annotations) **meaning changed**
  - before: Retrieve the full content of one CortexPlus memory item by id, as returned by search.
  - after: 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.

## Tools (11)

- `connect`: Complete the CortexPlus connection with the 6-digit code the user received by email after signup. Ask the user for the code, then call this tool with the same email used in signup; never guess or invent the code. The response includes an API key that the AI platform should save in its CortexPlus connector configuration.
- `context_packs`: List saved CortexPlus context packs, optionally filtered by AI platform.
- `fetch`: 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.
- `memory`: Save a memory in CortexPlus. CortexPlus decides whether it is a note, task, or reminder and extracts the client.
- `recall`: 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.
- `remember`: Store a note in the user's CortexPlus memory so future conversations can recall it.
- `resume`: Load a previously saved CortexPlus context pack to resume work started in another AI conversation.
- `save_context`: Save a handoff summary of this conversation to the user's CortexPlus memory so it can be resumed later in another AI platform. Write the summary yourself, in Markdown, covering: objective, decisions taken, current state, artifacts, next steps and constraints. Do not paste the raw transcript. Never include passwords, API keys or tokens.
- `search`: 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.
- `signup`: 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.
- `tasks`: List open CortexPlus tasks and reminders, optionally filtered by client.
