Pmll Memory MCP - install, status & alternatives [2026]

01 · Install Pmll Memory MCP

before you install - you'll need

Set PYP_WORKSPACE_ROOT, PYP_DEBUG, CUDA_VISIBLE_DEVICES, MEMORY_FILE_PATH before connecting.

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

npm package pmll-memory-mcp - unscoped; check the name against the project README before installing

registry namespace io.github.drQedwards is GitHub-verified and matches the repo owner

03 · What Pmll Memory MCP can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can set up PMLL silo + Q-promise state for session, create or update a memory node with auto-generated TF-IDF embeddings, create typed edges (relates_to, depends_on, implements, references, similar_to, contains), and remove decayed edges (e^(-λt) below threshold) and orphan nodes with low access.

Capability map

Tools grouped from the project's README - what Pmll Memory MCP lets an agent do.

Memory

3 tools - e.g. Create or update a memory node with auto-generated TF-IDF embeddings; Semantic search with graph traversal - direct matches + neighbor walk; Unified view of short-term KV and long-term graph memory status

upsert_memory_node · search_memory_graph · memory_status

Resolve

2 tools - e.g. "pending", payload?}; Unified context lookup: short-term KV → long-term graph → miss

resolve · resolve_context

create & write

2 tools - e.g. Create typed edges (relates_to, depends_on, implements, references, similar_to, contains); Bulk-add nodes with auto-similarity linking (cosine ≥ 0.72 creates edges)

create_relation · add_interlinked_context

Init

1 tool - e.g. Set up PMLL silo + Q-promise state for session

init

Peek

1 tool - e.g. Non-destructive cache + promise check

peek

update

1 tool - e.g. Store KV pair in the silo

set

Flush

1 tool - e.g. Clear all silo slots at task completion

flush

Graphql

1 tool - e.g. Execute GraphQL queries/mutations against the memory store

06 · Pmll Memory MCP FAQ

Is Pmll Memory MCP still maintained?

Yes - as of 2026-09-18, its last commit was 2026-09-10 and it shipped 4 releases in the last 90 days. We re-verify nightly.

What can Pmll Memory MCP do?

With this server connected, an agent can set up PMLL silo + Q-promise state for session, create or update a memory node with auto-generated TF-IDF embeddings, create typed edges (relates_to, depends_on, implements, references, similar_to, contains), and remove decayed edges (e^(-λt) below threshold) and orphan nodes with low access.

How do I install Pmll Memory MCP?

Run `npx -y pmll-memory-mcp`. The README documents 4 environment variables (PYP_WORKSPACE_ROOT, PYP_DEBUG, CUDA_VISIBLE_DEVICES…) to set first. Set PYP_WORKSPACE_ROOT, PYP_DEBUG, CUDA_VISIBLE_DEVICES, MEMORY_FILE_PATH before connecting. You can also paste the ready-made client config above.

Does Pmll Memory MCP run locally?

Yes - it's a stdio server: it runs on your machine (via npx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
