About adaptive-recall
Adaptive Recall is a hosted long-term memory server for AI applications. It combines several retrieval methods with cognitive scoring and memory lifecycle management, and adapts its ranking based on usage.
Key features
- 01Parallel vector, time, keyword, and graph search
- 02Cognitive-science-based memory ranking
- 03Automatically extracted entity graph
- 04Memory confidence and lifecycle stages
- 05Validated learning from query history
- 06Retrieval consistency and gap monitoring
Use cases
- 01Store and retrieve long-term AI application context
- 02Find memories through entity relationships
- 03Track evolving facts and confidence
- 04Check retrieval quality and knowledge gaps
MCP support
Connects to MCP clients as a hosted memory server, with Bearer-token authentication. Its actions include storing, recalling, updating, and removing memories, and exploring the knowledge graph.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.

Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

What It Does
Adaptive Recall is a hosted memory server that stores, retrieves, and manages long-term memory for AI applications. It connects via MCP or REST API.
- Multi-strategy retrieval: four search strategies run in parallel (vector similarity, temporal recency, full-text keyword, knowledge graph traversal) and the system learns which to prioritize for each type of query
- Cognitive scoring: results ranked using ACT-R activation modeling from cognitive science, factoring in recency, access frequency, entity connections, and validated confidence
- Knowledge graph: entities and relationships extracted automatically from stored memories, used as a retrieval pathway alongside text similarity
- Memory lifecycle: memories progress through stages, gain or lose confidence based on corroborating evidence, and fade naturally when unused
- Self-improving: ML models train on your usage patterns, every parameter change must pass statistical validation against real query history before being adopted
- Retrieval quality monitoring: the system verifies its own retrieval consistency and identifies knowledge gaps

MCP Configuration
Add to your MCP client config (Claude Code, Codex, Cursor, or any MCP-compatible tool):
{
"mcpServers": {
"adaptive-recall": {
"type": "url",
"url": "https://YOUR_SERVER_URL/mcp",
"headers": {
"Authorization": "Bearer YOUR_API_KEY"
}
}
}
}
For Claude Code, add this to .mcp.json in your project or ~/.claude/settings.json for global access. For Gemini CLI, add to ~/.gemini/settings.json using httpUrl instead of url. For Codex, add to your Codex MCP configuration.
REST API
Every action is also available as an HTTP endpoint at https://YOUR_SERVER_URL/v1/. All requests require a Bearer token in the Authorization header.
Actions
| Action | Description |
|---|---|
| store | Save a new memory. Generates embeddings and extracts entities automatically. |
| recall | Search memories using multi-strategy retrieval with cognitive scoring. |
| update | Modify an existing memory. Re-embeds automatically if content changes. |
| forget | Remove a memory by ID or by finding the closest match to a query. |
| graph | Explore the knowledge graph, traversing entity relationships by name and depth. |
| status | System health, memory counts, confidence distribution, and knowledge gap detection. |
| snapshot | Get a formatted overview of stored memories, organized by type. |
| feedback | Send feedback directly to the Adaptive Recall developers. |
Memory Types
When storing memories, assign a type that affects how the memory is managed:
Learning types (evolve over time, gain/lose confidence, have lifecycle stages):
general_knowledge- facts, observations, reference informationuser_knowledge- information about people and their preferences
Lookup types (static reference, no lifecycle):
callable_scripts- tool and script referenceswork_project- project tracking, tasks, deadlinescross_reference- pointers to external information and resourceslearned_procedure- multi-step workflows and procedures

Free, Starter, Pro, and Business plans available. See adaptiverecall.com for details.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
