Summary
A straightforward memory layer that lets Claude keep, recall, update, and forget information across conversations. It connects via streamable HTTP and gives you four core operations: store new facts, retrieve what's been saved, modify existing entries, and delete what's no longer relevant. Useful when you need session continuity without building your own persistence layer. Maindex provides the backend infrastructure with revision history, typed relationships, and a knowledge graph you can inspect through their dashboard. Works across multiple AI clients through MCP, so the same memory follows you whether you're in Claude, Cursor, or ChatGPT. The free tier gets you started, and collections can be locked behind passphrases if you're storing sensitive context.

Parameters* required
tagsarrayOptional tags for categorization.
contentstringPrimary text to store; required.
rewritebooleanFAILSAFE — defaults to false. When false (the default), content is stored exactly as provided with zero LLM processing. Set to true ONLY if the caller explicitly opts into LLM-assisted rewriting for improved clarity and structure. No content transformation occurs unless this flag is explicitly true.default: false
headlinestringOptional headline; Smart may generate one if omitted.
metadataobjectOpaque JSON metadata stored with the memory.
collectionsarrayCollection slugs or IDs to add the new memory to.
recallSearch and retrieve memories from Maindex (Smart). Modes: relevant (default), exact, current_state, history, recent. query is required unless mode is recent. Read-only for tenant memory data.4 params

querystringSearch text. Required unless mode is `recent`. Omit for a recency-sorted list (optionally filtered).

Parameters* required

Set to true ONLY if the caller explicitly opts into LLM-assisted rewriting for improved clarity and structure. No content transformation occurs unless this flag is explicitly true.default: false
target_idstringShort ID of the memory to update (mem-*).
forgetSoft-delete a memory by mem-* ID, or with wipe_history=true permanently purge all revisions (IRREVERSIBLE). When wipe_history is true, confirm_irreversible_wipe must also be true or a confirmation prompt is returned. Soft-delete (default) is safe and reversible.3 params
Soft-delete a memory by mem-* ID, or with wipe_history=true permanently purge all revisions (IRREVERSIBLE). When wipe_history is true, confirm_irreversible_wipe must also be true or a confirmation prompt is returned. Soft-delete (default) is safe and reversible.
Parameters* required
target_idstringShort ID of the memory to forget (mem-*).
wipe_historybooleanIf true, permanently purge all revisions and blank the body (IRREVERSIBLE). Otherwise soft-delete only. When true, confirm_irreversible_wipe must also be true or a confirmation prompt is returned instead.default: false
confirm_irreversible_wipebooleanRequired confirmation when wipe_history is true. Must be explicitly set to true to authorize irreversible permanent purge of all revisions. If wipe_history is true and this field is missing or false, the tool returns a confirmation prompt instead of executing the destructive action.default: false
