MCP server for Velixar persistent cognitive context — memory, identity, graph, time, and contradiction for LLMs
MCP server for Velixar persistent cognitive context — memory, identity, graph, time, and contradiction for LLMs. Exposed over MCP by the velixar mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.
The first cognitive memory server for AI assistants. Not a vector database wrapper — a full reasoning layer that gives your AI persistent memory, a knowledge graph, identity awareness, contradiction detection, and belief tracking across every session.
The server ships on npm as velixar-mcp-server, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Everything the assistant can do here goes through one of these:
Orientation — recall prior reasoning, build project context, profile an entity, orient-then-narrowConflict — resolve contradictions, identify knowledge gapsContinuity — trace belief evolution, resume sessions, reconstruct decision pathsLifecycle — distill sessions, consolidate topic memory, retag recent memoriesIdentity — summarize user identity, detect preference shifts, align response styleEnterprise — evaluate enterprise fit for a domainWebhook — POST /webhook/ci — generic CI event ingestionvelixar_store — Store a memory with tags, tier, and typevelixar_search — Semantic search across all memoriesvelixar_list — Browse with pagination and filteringvelixar_update — Edit content or tags on an existing memoryvelixar_delete — Remove a memoryYou will need 4 environment variables: VELIXAR_API_KEY, VELIXAR_WORKSPACE_ID, VELIXAR_API_URL, VELIXAR_USER_ID. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
This sits in the knowledge and memory group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Velixar's toolset — Orientation, Conflict, Continuity and 11 more — is a fair guide to whether it matches your workflow. It is maintained by velixarai; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

A knowledge graph your assistant keeps between sessions — entities, relations and observations that persist.
Kill hallucinated APIs — version-accurate, up-to-date library documentation injected straight into context.
Your workspace, on speaking terms with AI — search, read and write Notion pages and databases.
A structured scratchpad for hard problems — stepwise reasoning with revisions, branches and visible logic.
Symbol-level code navigation, refactoring and memory for coding agents — the IDE brain your assistant has been missing.
Chat with your second brain — search, read and write vault notes through the Local REST API.
