Tools: memory_write memory_search memory_export memory_import memory_forget memory_write_free memory_search_free memory_stats
memory_write | Store a memory permanently. Namespaced to YOUR paying wallet — your wallet is your private memory store. Semantic-indexed for later search. Optional supersedes=[ids] marks prior memories in your namespace as superseded by this one (excluded from search, still visible in export with their superseded_by id) — a Zep-style update-in-place without ever losing history. Paid: $0.001 per write via x402 (p params: content*, tags, supersedes |
memory_search | Semantic search over YOUR stored memories (payer-wallet namespace). Returns top-k by embedding similarity. Paid: $0.002 per search via x402. params: query*, k |
memory_export | Export memories in YOUR payer-wallet namespace (up to 1000/call, newest first; use offset to page through namespaces >1000). Your data is yours. Includes superseded_by so history is exportable. Paid: $0.01 via x402. params: offset |
memory_import | Bulk-write memories into YOUR namespace (max 200/call, content <=8k chars each). Accepts the exact shape memory_export emits, so a whole namespace can move in with one paid call. Embeds best-effort; missing embeddings are backfilled hourly. Paid: $0.01 flat via x402. params: memories* |
memory_forget | Delete memories by id from YOUR namespace (or a namespace you hold a write/rw grant for). Max 100 ids per call. Paid: $0.001 per call via x402. params: ids* |
memory_write_free | FREE (no payment): store a memory in YOUR namespace, proven by an EIP-191 personal_sign instead of an x402 payment. wallet_auth = base64 JSON {address,ts,signature} where signature = personal_sign of 'borismem-free:<address>:<ts>' (ts within 600s). Writes to the SAME namespace paid calls use. Capped at 1000 writes / rolling 30 days per wallet; over cap returns an error pointing to the paid tier. params: content*, tags, wallet_auth* |
memory_search_free | FREE (no payment): semantic search over YOUR namespace, proven by an EIP-191 personal_sign. Same wallet_auth scheme as memory_write_free. Capped at 500 searches / rolling 30 days per wallet. params: query*, k, wallet_auth* |
memory_stats | FREE: count + last-write timestamp for any wallet namespace. Content is never returned on the free tier. params: namespace* |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
