### Description (declared)

# mcp_context_pointer

**A plug-in extension for [Model Context Protocol (MCP)](https://modelcontextprotocol.io) enabling Cross-App Memory Pointers (ContextPointer block) and seamless use of vaulted memory with LLM agents.**  
_Built by Third Plane._

## 🚀 What is this?

`mcp_context_pointer` is an optional plug-in for the MCP Python SDK.  
It provides the **ContextPointer block**—an efficient, privacy-stable, cross-application pointer for referencing conversation history, memory chunks, or arbitrary state, backed by a vault service.

- **Save up to 40–60% on LLM context tokens**
- **Enable compliance (GDPR, Consent Ledger) and auditability**
- **Point to fast, managed vaults** or your own self-hosted instance

Supports:
- Adaptive inlining out-of-the-box (fallbacks when vault or network is slow)
- Signature verification (Ed25519/PASETO or HMAC)
- Works with **any** MCP-compliant service, agent, or app

## 🛠️ Installation

```bash
pip install mcp-context-pointer
# or as an MCP extra:
pip install "modelcontextprotocol[context-pointer]"
```

---

## 💡 Quick Start

```python
from mcp_context_pointer.block import ContextPointerBlock
from mcp.blocks.registry import get_block
import requests

# Compose a conversation:
history = [
    {"role": "user", "text": "Can you summarize our last meeting?"},
    {"role": "assistant", "text": "Certainly, here's a short summary..."},
    {"role": "user", "text": "What was the action item?"}
]

# Inline last N, pointerize the rest:
from mcp_context_pointer.wrap import wrap_history_with_pointer

new_blocks = wrap_history_with_pointer(
    history=history,
    n_inline=2,
    vault_url="https://vault.thirdp…
