The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
add_memory Add memory ~205
Save a new Brain memory when the user explicitly asks to remember, save, or store something. Store either one singular fact or one short Markdown mini-doc (headings, lists, bold, links, code, and Mermaid diagrams) up to about 800 words. Use one memory for one coherent fact or note; do not paste a long document. A new memory that contradicts or restates an older one replaces it; the older one stays in version history.
| Name | Type | Req | Description |
|---|---|---|---|
| brain | string | yes | Brain id from list_brains. The personal brain is "personal". |
| category | string | – | – |
| confidence | number | – | – |
| content | string | yes | Memory text: one singular fact, or one short Markdown mini-doc (headings, lists, bold, links, code, and Mermaid diagrams in ```mermaid fences). Keep it under about 800 words. Hard cap 4000 characters. |
| entityType | string | – | – |
| kind | string | – | – |
No output schema declared.
No examples provided.
delete_memory Delete memory ~85
Delete a Brain memory when the user explicitly asks to remove a saved fact. The memory leaves search and reads, and every saved version is kept so the user can restore it with `npx @make0-ai/brain restore <id>`.
| Name | Type | Req | Description |
|---|---|---|---|
| brain | string | yes | Brain id from list_brains. The personal brain is "personal". |
| memoryId | string | yes | – |
No output schema declared.
No examples provided.
get_memory Get memory ~100
Fetch one Brain memory by id. Content is either a singular fact or a short Markdown mini-doc (up to about 800 words). The memory includes addedBy (who first saved it) and versionCount (saved revisions). When versionCount is greater than 1, call get_memory_versions to read every saved revision.
| Name | Type | Req | Description |
|---|---|---|---|
| brain | string | yes | Brain id from list_brains. The personal brain is "personal". |
| memoryId | string | yes | – |
No output schema declared.
No examples provided.
get_memory_versions Get memory versions ~87
Fetch every saved version of one Brain memory, newest first, including the current version. Use this when you need to see how a fact changed. Each version includes its full content. The version with current: true matches the memory returned by get_memory.
| Name | Type | Req | Description |
|---|---|---|---|
| brain | string | yes | Brain id from list_brains. The personal brain is "personal". |
| memoryId | string | yes | – |
No output schema declared.
No examples provided.
list_brains List brains ~36
List Make0 brains this connection can use. Call this first to get a brain id for search_brain. Does not list memories.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
search_brain Search brain ~256
Search saved Brain memories. A memory may be a singular fact or a short Markdown mini-doc. Use a short, focused query with the key people, entities, preferences, or topics needed—not the full user message. Memories are retrieved with semantic + BM25 keyword search, reranked by a MiniLM cross-encoder, then expanded up to two hops along related_to graph links so connected memories surface with the seeds. Each memory includes addedBy (who first saved it) and versionCount (saved revisions). When versionCount is greater than 1, call get_memory_versions for the full history. Call get_memory whenever a result has truncated: true so you read the full note, not a clipped preview. Always pass brain from list_brains.
| Name | Type | Req | Description |
|---|---|---|---|
| brain | string | yes | Brain id from list_brains. The personal brain is "personal". |
| entityType | string | – | Optionally restrict results to one memory entity type. |
| kind | string | – | Optionally restrict results to work or profile memories. |
| limit | integer | – | Maximum memories to return (1-64). Score-gated, then padded to at least 10 when candidates exist. |
| query | string | yes | Focused query for the saved facts needed. |
No output schema declared.
No examples provided.
update_memory Update memory ~186
Update an existing Brain memory when the user asks to correct or change it. The new content can be a singular fact or a short Markdown mini-doc (headings, lists, bold, links, code, and Mermaid diagrams) up to about 800 words. New content replaces the old content, and the previous version is kept.
| Name | Type | Req | Description |
|---|---|---|---|
| brain | string | yes | Brain id from list_brains. The personal brain is "personal". |
| category | string | – | – |
| confidence | number | – | – |
