MCP server for 0Latency — persistent memory layer for AI agents. Give Claude, Cursor, or any MCP client long-term memory.
Context Mem is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.
Open InstallationWhat it does
Memory + context infrastructure for AI agents. LLM Wiki auto-sync, 15 content-aware summarizers, hybrid search (BM25 + vector + optional LLM judge), entity intelligence, decision trails, Obsidian plugin. Fully local, zero cost. MIT.
Quickstart
# 1 — run it from where its publisher ships it
npx -y context-mem
# 2 — ask your agent something

Context Mem is free: there is no plan to choose, no cap to set and nothing that can bill you.
Collected from a public index. Nobody has claimed this account, so nothing here was written by its author — claim it if it is yours.
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. This one runs on your machine: your client starts Context Mem as a process under your own user, with your files and your network, so the tool surface below is what it can do to your computer rather than to a server somewhere else. It is scanned, signed and pinned to the version you choose — read the surface before you approve it.
This is a public server: you run it yourself and this marketplace is not in the path. Claude Code registers it in one command.
claude mcp add context-mem-mcp -- npx -y context-memReconnect, or start a new session, and the tools appear in the model’s tool list.
One config entry your client uses to start the process locally. A local server runs with your file system and your network, which is why it is priced without metering.
44 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.
Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.

Query knowledge that was valid at a specific point in time. Returns facts that were active at the given timestamp.
Takes no parameters.
Generate a human-readable narrative from session data. Formats: pr (pull request), standup, adr (architecture decision record), onboarding.
Takes no parameters.
Reconstruct the evidence chain behind a code change or decision. Returns the trail of events that led to a decision.
Takes no parameters.
Predict which memory entries are at highest risk of being forgotten or archived. Users can pin important entries to protect them.
Takes no parameters.
Generate a scored session primer with 4-layer context: project profile, critical knowledge, recent decisions, and top entities.
Takes no parameters.
[v4] Unified search across observations, knowledge, content, topics. Legacy search/search_knowledge/search_content/recall/browse/global_search/ask are aliased to this with deprecation _meta.
Takes no parameters.
Index content into the content store with code-aware chunking for later search.
Takes no parameters.
Search the content store for indexed content chunks.
Takes no parameters.
Search the knowledge base using 3-layer search (FTS5 → trigram → scan). Optionally include global cross-project knowledge. By default only returns currently-valid facts (valid_to IS NULL).
Takes no parameters.
Verbatim memory retrieval with importance filtering and rich attribution. Returns original content, not summaries.
Takes no parameters.
Ask a natural language question about the project. Searches knowledge, observations, events, and graph entities.
Takes no parameters.
Browse observations by topic, person, or time dimension.
Takes no parameters.
Update the project quick profile — a 3-5 line summary shown at every session start. Auto-generates from knowledge if no content provided.
Takes no parameters.
Get current budget usage and status for the session.
Takes no parameters.
Configure budget settings (session limit, overflow strategy).
Takes no parameters.
Restore a previous session snapshot by session ID.
Takes no parameters.
Emit a context event with priority and metadata.
Takes no parameters.
Query context events with optional filters.

What counts against your monthly calls
| Tool | Unit | Calls used | Out of the allowance |
|---|
Nothing here is billable. Context Mem costs nothing to install and nothing to call, at any volume.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
| Term | Level | What it prices | Points |
|---|---|---|---|
| −6.3 | |||
| −3.15 | |||
| capability-exposure | high | capability blast radius (high) — client exposure if the model is manipulated | −6 |
| verification-discount | none | publisher verification (unlinked) — no provenance/repo link, but the shipped source was fully read | −2 |
| coverage-honesty | source | inspection depth (source) — how much of the target the scan could see | −0 |
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
No tools were enumerated, so prompt-injection, capability and toxic-flow analysis had no tool surface to inspect. To grade a package’s real runtime tools, scan the running server: --command "npx -y <package>".
Capability — what it could do if the model were manipulated
Tags derived from each tool’s schema and the implementation, not from what the tool calls itself. high is the level these add up to.
| Tool | Capability tags | Why the tag was assigned |
|---|---|---|

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.
Supply chain and provenance
This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.
Release history
Pinned to 4.0.0 — the install command below asks for that release. A pin is part of an install, so it is kept for this visit and written down when you install.
No release note was published with this version.
Only accounts with at least 50 real tool calls against this server in the last 90 days can post. Ratings are weighted by how much the reviewer actually uses it, and publishers can reply once per review.
Writing one takes an account with at least 50 real tool calls against Context Mem in the last 90 days. That is the whole gate — there is no other way to post, which is why the counts beside each review are worth reading.
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes an account with 50 real tool calls against it.
