Pmll Memory MCP README | AllMCPs

PPM — Python Package Manager

pypm packaging CLI with shared PMLL memory + Q-promise. Sibling: drQedwards/pmll.

Live Stellar pmll-anchor IDs: docs/STELLAR.md · skills: SKILL.md · promises: Q_promise_lib/README.md.

TL;DR: PPM packages Python (C CLI). Shared PMLL owns memory/state (memory_silo_t, exact peek + semantic peek_semantic, SAT bridge, init_pml). Q-promise owns temporal/control-flow (qpromise_*, libqpromise.so) — it does not replace the silo. Optional Stellar commitments hash off-chain CodeworkPayloads into 32-byte digests via pmll-anchor (ABI: init/store/get/bump). Companion packaging CLI + MCP memory server live in-tree.

PMLL provides durable structured memory for agent workflows, alongside a PPM packaging CLI (hermetic bundles, plugins, signing) and the PMLL Memory MCP server. Long-term graph tools adapt Context+.

Layers (post-merge)

Two complementary layers — not substitutes for each other:

Layer	Owns	Key surface
PMLL	Durable memory / state	`memory_silo_t`, `peek` / `peek_semantic`, `silo_set`, SAT bridge, `init_pml`
Q-promise	Temporal / control-flow	`qpromise_*` API, `libqpromise.so`, deferred `qpromise_drain()`

Q-promise does not replace the silo. A promise may reference a memory key (and optional SAT state id); results are committed back with silo_set / qpromise_resolve_commit.

Intended loop

Code

retrieve (peek / peek_semantic)
  → compute / request work
  → promise PENDING
  → resolve / reject (optionally resolve_commit → silo)
  → continuation (then / catch / finally via qpromise_drain)
  → memory update
  → retrieve again

Thread safety: the C Q-promise drain is single-threaded. Continuations run only during qpromise_drain() on the calling thread; callers must externally serialize access. Details: Q_promise_lib/README.md.

C core (PMLL)

Headers: PMLL.h · implementation: PMLL.c

Symbol	Role
`memory_silo_t`	Associative/semantic silo: `tree`, `slots[]`, `embed_dim` (`PMLL_EMBED_DIM=32`), `slot_count`
`silo_slot_t`	`key`, `content`, `embedding`, `resolved`
`init_silo` / `free_silo` / `silo_set`	Allocate, free, write key/content + embedding
`peek`	Exact key, else index
`peek_semantic`	Cosine ≥ `min_sim` over embeddings (`silo_embed_text`, `silo_cosine_similarity`)
`init_pml`	Sets every `assignment[i] = -1` (undecided)
`check_conflict`	Treats `-1` as undecided (not sticky false from zero-fill)
`sat_bridge_*`	Map 3SAT tokens → associative string literals in the silo

Q-promise library

Build / test / API: Q_promise_lib/README.md (authoritative). Public symbols are qpromise_*; shared object is libqpromise.so. The old prototype (QMemNode / q_mem_* / memory-chain walker) is removed; Q_promises.h is a compatibility include redirecting to qpromise.h.

🧠 PMLL Memory MCP Server

Persistent memory logic loop with short-term KV context memory, Q-promise deduplication, and Context+ long-term memory graph designed to improve context retention and retrieval for coding agents.

pmll-memory-mcp is a Model Context Protocol (MCP) server with complementary short-term KV and optional long-term graph layers. Server construction prefers MCPServer (mcp 2.x) and falls back to FastMCP (mcp 1.x) — see mcp/pmll_memory_mcp/server.py.

Ground tool names in code: TypeScript (mcp/src/index.ts) has 15 tools including graphql and names like create_relation; Python (mcp/pmll_memory_mcp/server.py) has 14 tools (no graphql) with several longer names such as create_memory_relation. A ctypes demo in Ppm-lib/pmll_mcp/ loads libqpromise.so via qpromise_*.

Memory layers:

Short-term KV cache (5 tools) — session-isolated key-value memory with Q-promise deduplication, mirroring PMLL.c::memory_silo_t.
Long-term memory graph (6 tools) — adapted from Context+ by @ForLoopCodes, providing a SQLite-backed property graph with typed nodes, weighted edges, temporal decay scoring (e^(-λt)), and semantic search via stable hashing embeddings.
Solution engine (3 tools) — bridges both layers with unified context resolution (short-term → long-term → miss), auto-promotion of frequently accessed entries, and unified memory status views.

The server is designed to be the 3rd initializer alongside Playwright and other MCP tools — loaded once at the start of every agent task. Agents call init once at task start, then use peek before any expensive MCP tool invocation to avoid redundant calls. Frequently accessed entries are promoted to the long-term memory graph for semantic retrieval across sessions (SQLite-backed graph).

Tool counts differ by implementation (TS 15 incl. graphql; Python 14 — see note above). Historical docs below list the TypeScript tool surface.

Why it's a premium 3rd initializer

Modern Claude agent tasks routinely call Playwright, file-system tools, and other MCP servers. Without a shared memory layer, every subtask re-initializes the same context from scratch. pmll-memory-mcp eliminates this overhead with two complementary memory layers:

Code

Agent task start
  ├── 1st init: Playwright MCP
  ├── 2nd init: Unstoppable Domains MCP  (see unstoppable-domains/)
  └── 3rd init: pmll-memory-mcp   ← this server
        ├── Short-term: all tool calls go through peek() first
        └── Long-term: frequently accessed entries auto-promote to graph

The `peek()` pattern

Before every expensive MCP tool invocation, agents call peek to check the cache:

server.ts

// Pseudocode — what the agent does automatically via MCP tool calls

// 1. Check cache before navigating
const result = mcp.call("pmll-memory-mcp", "peek", { session_id: sid, key: "https://example.com" });
if (result.hit) {
    const pageContent = result.value;          // ← served from PMLL silo, no browser needed
} else {
    // 2. Cache miss — do the real work
    const pageContent = mcp.call("playwright", "navigate", { url: "https://example.com" });
    // 3. Populate the cache for future agents / subtasks
    mcp.call("pmll-memory-mcp", "set", {
        session_id: sid,
        key: "https://example.com",
        value: pageContent,
    });
}

⚓ Stellar commitments (`pmll-anchor`)

Memory / codework payloads stay off-chain. Optional 32-byte SHA-256 commitments are live on Stellar mainnet via Soroban pmll-anchor (shared with drQedwards/pmll). ABI unchanged: init / store / get / bump only — do not invent fields or contract IDs. This PPM tree may not include the full pmll-anchor/ contract sources; typed payload is still mirrored as skill.ts. Invoke docs / contract source: pmll/SKILL.md. Local summary: SKILL.md.

  PMLL.c / PMLL.h      Q_promise_lib/
  (memory_silo_t)       (qpromise_* / libqpromise.so)

Key components

File / Directory	Purpose
`Ppm.c`	C-core CLI v0.0.3-dev — integrated single-file build (~500 LOC)
`Pypm.c`	PyPM 0.3.x front-door dispatcher; delegates to module sources
`PMLL.c` / `PMLL.h`	Associative/semantic silo, peek/peek_semantic, SAT bridge, init_pml=-1
`SAT.c` / `SAT.h`	Boolean SAT solver used for dependency resolution
`Q_promise_lib/`	Promise/continuation library (`qpromise_*`, `libqpromise.so`; single-threaded drain)
`skill.ts` / `SKILL.md`	Off-chain CodeworkPayload + Stellar skills entry
`pmll-anchor/`	Soroban commitment contract (source on pmll; may be absent here)
`lattice/`	On pmll only — playable Stellar skills graph / ARC-AGI-3 play test
`mcp/`	TypeScript PMLL Memory MCP server (15 tools)
`mcp/src/memory-graph.ts`	Long-term memory graph adapted from Context+
`mcp/src/solution-engine.ts`	Solution engine bridging short-term KV + long-term graph
`mcp/src/embeddings.ts`	TF-IDF embeddings and cosine similarity for semantic search
`CLI/`	Extended CLI interface
`Panda-lib/` `Torch-lib/` `Numpy-lib/`	Library integration shims
`scripts/`	Build helpers and automation scripts

📝 Release Notes

Post-merge (2026-08) — semantic silo + Q-promise

PMLL C core: associative/semantic silo (slots + embeddings), peek + peek_semantic, SAT bridge, init_pml assignments start at -1 (undecided).
Q-promise evolved to qpromise_* + libqpromise.so; prototype QMemNode / q_mem_* API removed.
Stellar skills / skill.ts aligned for off-chain CodeworkPayload hashing into existing pmll-anchor (ABI unchanged).
MCP servers prefer MCPServer with FastMCP fallback; Q-promise MCP demos load libqpromise.so.

pypm 0.0.3-dev (25 Jun 2025)

New & Improved

Area	What's new
Unified source	v0.0.1 + v0.0.2 merged into a single `pypm.c` file to simplify builds.
Version bump	CLI now reports `0.0.3-dev`.
Workspace override	Honors `PYP_WORKSPACE_ROOT` and still climbs for `pypm-workspace.toml`.
Doctor v2.1	Counts issues and exits with that count; inline Python probe via here-doc.
Sandbox v2.1	`-d <DIR>` flag; default remains `mkdtemp`.
Plugin fetcher hardening	Creates `~/.pypm/plugins` safely; `CURLOPT_FAILONERROR` for HTTP 4xx/5xx; preserves plugin exit code.
Hermetic bundle flag	`pypylock -o <file>` works regardless of flag order; default `dist/venv.tar.gz`.
Error surfacing	`fatal()` now shows `errno` via `perror`; `dlopen`/`curl` errors bubble up.

Fixes

CLI flags after sub-commands were occasionally skipped by getopt → optind = 2 before parsing.
Plugin loader returned success even when dlsym failed → now returns non-zero and closes handle.
Workspace scan no longer overwrites cwd for later getcwd() calls.

Breaking changes

pypm version is now a sub-command (not --version flag).
doctor exit codes can now be >1 (numeric issue count).

Migration (0.0.2 → 0.0.3-dev)

If you did …	Do this now
`./pypm doctor && echo OK`	Check `[[ $? -eq 0 ]]` or parse the numeric count.
Used `pypm_v002.c` / `pypm_v001.c`	Switch to `pypm.c`, `make clean && make`.
Hard-coded `dist/venv.tar.gz` path	Pass `-o` flag for custom output paths.

Known issues

Windows build needs: LoadLibraryW, _mktemp_s, bsdtar.exe fallback (#22).
pypylock relies on shell tar; libarchive port planned for 0.0.4.
WASI/Rust/OpenSSL checks are informational stubs only.

pmll-memory-mcp 1.0.1

Version bump — bumped from 1.0.0 to 1.0.1 to fix PyPI publishing (1.0.0 already existed on PyPI).
Updated project descriptions — PyPI and npm package descriptions now include "in Claude Sonnet/Opus agent tasks" to match the mcp/README.md tagline.
README refresh — PPM README.md MCP section updated with full tool reference, peek() pattern with TypeScript example, VS Code MCP configuration, and companion servers table from mcp/README.md.

pmll-memory-mcp 1.0.0

Context+ integration — 6 long-term memory graph tools adapted from Context+ by @ForLoopCodes: upsert_memory_node, create_relation, search_memory_graph, prune_stale_links, add_interlinked_context, retrieve_with_traversal.
Solution engine — 2 new tools + 1 status tool bridging short-term KV cache with long-term memory graph: resolve_context, promote_to_long_term, memory_status.
GraphQL tool — graphql tool for flexible query/mutation access.
15 total tools (5 short-term KV + 1 GraphQL + 6 long-term graph + 3 solution engine).
TF-IDF embeddings with cosine similarity search across the memory graph.
Temporal decay scoring (e^(-λt)) on graph edges with automatic pruning.
Auto-similarity linking (cosine ≥ 0.72) on bulk context additions.
Unified context resolution path: short-term → long-term → miss.

pmll-memory-mcp 0.2.0

Initial MCP Registry submission.
Five tools: init, peek, set, resolve, flush.
TypeScript KV store mirroring PMLL.c::memory_silo_t.
Q-promise registry (historical); current C API is qpromise_* / libqpromise.so.
Docker multi-stage image with persistent volume support.
Companion Unstoppable Domains MCP server included in mcp/unstoppable-domains/.

pypm 0.0.2 (25 Jun 2025)

Workspace autodetect, Doctor v2, Sandbox upgrade, Plugin add/run, pypylock -o. Breaking: --version flag removed; doctor exits non-zero on issues.

pypm 0.0.1 (23 Jun 2025)

Initial proof-of-concept — single-file CLI with doctor, sandbox, plugin, and pypylock.

🗺 Roadmap

Version	Planned features
