MCP 服务器

Paper Memory MCP Lite

Local-first MCP server for indexing and searching research materials (papers, notes, logs, READMEs) using SQLite FTS, with tools for memory management and evidence retrieval.

README

Paper Memory MCP Lite

Local-first MCP-style research memory for papers, notes, figures, experiment logs, and GitHub README files.

Paper reading gets messy fast: one PDF has the key idea, one Markdown note has your interpretation, one experiment log has the actual failure, and one README has the code status. This project gives agents a tiny local memory layer that indexes those files and exposes search through a simple MCP-compatible stdio server.

It is intentionally small: no cloud database, no embeddings service, no account, no background daemon. Everything lives in a local SQLite file.

If this helps your research workflow, a star helps other people find it.

Features

Index Markdown, text, JSON, YAML, and lightweight PDF text when optional PDF tooling is installed.
Store paper notes, figure captions, experiment logs, repo READMEs, and daily briefings in one SQLite FTS database.
Search snippets with source path, title, kind, and timestamp.
Expose MCP-style tools:
- index_research_folder
- search_research_memory
- get_daily_context
- link_paper_to_experiment
- summarize_evidence_pack
Run as a CLI for smoke tests or as a stdio JSON-RPC server for agents.

Quick Start

git clone https://github.com/StaryMoon/paper-memory-mcp-lite.git
cd paper-memory-mcp-lite
python3 -m venv .venv
source .venv/bin/activate
pip install -e .

MCP Server

Add this to an MCP client configuration and adjust the path:

{
  "mcpServers": {
    "paper-memory-lite": {
      "command": "python3",
      "args": ["-m", "paper_memory_mcp_lite.server", "serve"],
      "env": {
        "PAPER_MEMORY_DB": "/absolute/path/to/paper-memory.sqlite"
      }
    }
  }
}

See docs/mcp-config.json for a copyable example.

Tool Behavior

Tool	Purpose
`index_research_folder`	Index a folder of Markdown, text, JSON, YAML, and optional PDF text.
`search_research_memory`	Search local research notes and return snippets with file paths.
`get_daily_context`	Retrieve the most recent notes, logs, and briefings for daily planning.
`link_paper_to_experiment`	Store a lightweight relationship between a paper note and an experiment log.
`summarize_evidence_pack`	Build an evidence pack from search results without pretending it is a full literature review.

CLI Examples
