MCP server for 0Latency — persistent memory layer for AI agents. Give Claude, Cursor, or any MCP client long-term memory.
Free
Nothing to run from here
Claude Soul 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.

What it does
Give Claude Code a soul — persistent identity, cross-session learning, and evolving cognitive frameworks
Quickstart
# 1 — run it from where its publisher ships it
npx -y claude-soul
# 2 — ask your agent something
> Give Claude Code a soul — persistent identity, cross-session learning, and evolving cognitive frameworks
Claude Soul is free: there is no plan to choose, no cap to set and nothing that can bill you.

Installation
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 Claude Soul 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.
Claude Codedeclared by this listing
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 claude-soul-mcp -- npx -y claude-soulReconnect, or start a new session, and the tools appear in the model’s tool list.
Free to install, and it runs from its publisher’s own package: no account, no key, no card.
What it writes
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.
What you approve
15 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Takes no parameters.
Example callreturns →
Load a single framework with full details: description, evidence history, tier, and relationships.
Takes no parameters.
Example callreturns →
Record observed signals from this interaction. Use when you notice patterns the automatic extractor might miss.
Takes no parameters.

Example callreturns →
Write to a soul file. SOUL.md, SHADOW.md, STORY.md, CORRECTIONS.md, BONDS.md, MORTAL.md, GROWTH.md, PRINCIPLES.md, EDGES.md are writable. STATE.md and FRAMEWORKS.md are auto-managed.
Takes no parameters.

Get current system status — framework count, learning phase, signal count, last reflection time.
Takes no parameters.
Example callreturns →
Trigger a reflection cycle. Quick: tests frameworks against recent signals. Deep: full analysis with framework discovery. Meta: audits framework coherence and redundancy.
Takes no parameters.
Example callreturns →
Record a self-evaluation of a complex response. Be descriptive:

Semantic search across all memories and journal entries. Returns results ranked by meaning-similarity. Falls back to keyword search if Ollama is not available.
Takes no parameters.

BTrust score 84 / 100
Release 0.2.5 · scanned 26 Aug 2026
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.

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.

Live transportnot available
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.

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.

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.

Pinned to 0.2.5 — 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.

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.
Reviews are earned
Writing one takes an account with at least 50 real tool calls against Claude Soul 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.
No reviews yet
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.
