What it does

Sub-5ms topological 4D associative memory coprocessor for LLMs and multi-agent swarms.

Quickstart

# 1 — add it to Claude Code
claude mcp add --scope user --transport http calera-infinite-context-icx-persistent-memory-mcp https://icx.caleralabs.com/mcp --header 'X-License-Key: ${X_LICENSE_KEY}' --header 'X-Space-ID: ${X_SPACE_ID}'

# 2 — ask your agent for something these tools do
#   claim_1m_nodes, dispatch_actuation, icx_exec and 22 more

It needs X_LICENSE_KEY (Calera Labs API Key (obtain free at https://dashboard.caleralabs.com)), X_SPACE_ID (Memory partition namespace (default: 'default')): this sends them in the X-License-Key and X-Space-ID headers from your environment, so export them first — its endpoint answers 401 without them.

Calera Infinite Context (ICX) — Persistent Memory costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation

Where are you running it?

Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.

Claude Codedeclared by this listing

This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it. Claude Code reads X_LICENSE_KEY (Calera Labs API Key (obtain free at https://dashboard.caleralabs.com)), X_SPACE_ID (Memory partition namespace (default: 'default')) from your environment each time it connects and sends them in the X-License-Key and X-Space-ID headers — its endpoint answers 401 without them — so the key stays out of its config: export them in your shell profile (macOS, Linux), or run setx X_LICENSE_KEY …, setx X_SPACE_ID … and open a new terminal (Windows).

claude mcp add --scope user --transport http calera-infinite-context-icx-persistent-memory-mcp https://icx.caleralabs.com/mcp --header 'X-License-Key: ${X_LICENSE_KEY}' --header 'X-Space-ID: ${X_SPACE_ID}'

Reconnect, or start a new session, and the tools appear in the model’s tool list.

Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add — but its publisher asks for a key of their own on every call.

What it asks of you

It reaches a system of yours, so it needs your own credential rather than the publisher’s: X-License-Key header — Calera Labs API Key (obtain free at https://dashboard.caleralabs.com). You set it in your own client’s config, on your machine — this marketplace never holds it.

What it writes

One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.

ATool-list grade · score 90 / 100

Release 1.4.0 · scanned 28 Oct 2026

Graded from the tools this server lists, not from its source code.

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

score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.

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.

The scan read each tool’s name, description, input schema and annotations exactly as the server listed them the last time it answered us; no code was reviewed. We ask the server again about once a month, and a list that changed is graded again.

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.
