# 🚀 McpStore - Add MCP Capabilities to Your Agent in Three Lines of Code

`McpStore` is a tool management library specifically designed to solve the problem of Agents wanting to use `MCP (Model Context Protocol)` capabilities while being overwhelmed by MCP management.

`MCP` is rapidly evolving, and we all want to add `MCP` capabilities to existing `Agents`, but introducing new tools to `Agents` typically requires writing a lot of repetitive `"glue code"`, making the process cumbersome 😤



## Implement MCP Tools Ready-to-Use in Three Lines of Code ⚡

No need to worry about `mcp` protocol and configuration details, just use intuitive classes and functions with an `extremely simple` user experience.

```python
# Import MCPStore library
from mcpstore import MCPStore
# Step 1: Initialize a Store, which is the core entry point for managing all MCP services
store = MCPStore.setup_store()
# Step 2: Register an external MCP service, MCPStore will automatically handle connection and tool loading
store.for_store().add_service({"name":"mcpstore-wiki","url":"http://mcpstore.wiki/mcp"})
# Step 3: Get a tool list fully compatible with LangChain, ready for direct use with Agent
tools = store.for_store().for_langchain().list_tools()
# At this moment, your LangChain Agent has successfully integrated all tools provided by mcpstore-wiki
```



## A Complete Runnable Example - Direct Integration of MCP Services with LangChain 🔥

Below is a complete, directly runnable example showing how to seamlessly integrate tools obtained from `McpStore` into a standard `langChain Agent`.

```python
from langchain.agents import create_tool_calling_agent, AgentExecutor
from langchain_core.prompts import ChatPromptTemplate
from langchain_openai import ChatOpenAI
from mcpstore import MCPStore
store = MCPStore.setup_store()
store.for_store().add_service({"name":"mcpstore-wiki","url":"http://mcpstore.wiki/mcp"})
tools = store.for_store().to_langchain_tools()
llm = ChatOpenAI(
    temperature=0, model="deepseek-chat",
    openai_api_key="sk-****",
    openai_api_base="https://api.deepseek.com"
)
prompt = ChatPromptTemplate.from_messages([
    ("system", "You are an assistant, answer with emojis"),
    ("human", "{input}"),
    ("placeholder", "{agent_scratchpad}"),
])
agent = create_tool_calling_agent(llm, tools, prompt)
agent_executor = AgentExecutor(agent=agent, tools=tools, verbose=True)
query = "How's the weather in Beijing?"
print(f"\n   🤔: {query}")
response = agent_executor.invoke({"input": query})
print(f"   🤖 : {response['output']}")
```



Or if you don't want to use `langchain` and plan to `design your own tool calls` 🛠️

```
from mcpstore import MCPStore
store = MCPStore.setup_store()
store.for_store().add_service({"name":"mcpstore-wiki","url":"http://mcpstore.wiki/mcp"})
tools = store.for_store().list_tools()
print(store.for_store().use_tool(tools[0].name,{"query":'Beijing'}))
```



## Quick Start

### Installation
```bash
pip install mcpstore
```


## Chaining Calls ⛓️

I really dislike complex and overly long function names. For intuitive code display, `McpStore` uses `chaining`. Specifically, `store` is a foundation. If you have different `agents` and want your different `agents` to be experts in different domains (using isolated different `MCPs`), you can try `for_agent`. Each `agent` is isolated, and you can determine your `agent`'s identity through a custom `agentid`, ensuring it performs better within its scope.

* `store.for_store()`: Enter `global context`, where managed services and tools are visible to all Agents.
* `store.for_agent("agent_id")`: Create an `isolated private context` for an Agent with the specified ID. Each


## Multi-Agent Isolation 🏠

The following code demonstrates how to use `context isolation` to assign `dedicated tool sets` to Agents with different functions.

```python
# Initialize Store
store = MCPStore.setup_store()

# Assign dedicated Wiki tools to "Knowledge Management Agent"
# This operation is performed in the "knowledge" agent's private context
agent_id1 = "my-knowledge-agent"
knowledge_agent_context = store.for_agent(agent_id1).add_service(
    {"name": "mcpstore-wiki", "url": "http://mcpstore.wiki/mcp"}
)

# Assign dedicated development tools to "Development Support Agent"
# This operation is performed in the "development" agent's private context
agent_id2 = "my-development-agent"
dev_agent_context = store.for_agent(agent_id2).add_service(
    {"name": "mcpstore-demo", "url": "http://mcpstore.wiki/mcp"}
)

# Each Agent's tool set is completely isolated without affecting each other
knowledge_tools = store.for_agent(agent_id1).list_tools()
dev_tools = store.for_agent(agent_id2).list_tools()
```
Intuitively, you can use almost all functions through `store.for_store()` and `store.for_agent("agent_id")` ✨


## McpStore's setup_store() 🔧


### 📋 Overview

`MCPStore.setup_store()` is MCPStore's `core initialization method`, used to create and configure MCPStore instances. This method supports `custom configuration file paths` and `debug mode`, providing `flexible configuration options` for different environments and use cases.

### 🔧 Method Signature

```python
@staticmethod
def setup_store(mcp_config_file: str = None, debug: bool = False) -> MCPStore
```

**Parameter Description**:
- `mcp_config_file`: Custom mcp.json configuration file path (optional)
- `debug`: Whether to enable debug logging mode (optional, default False)
- **Return Value**: Fully initialized MCPStore instance

### 📋 Parameter Details

#### 1. `mcp_config_file` Parameter

- **When not specified**: Uses default path `src/mcpstore/data/mcp.json`
- **When specified**: Uses the specified `mcp.json` configuration file to instantiate your store, supports `mainstream client file formats`, `ready to use` 🎯

#### 2. `debug` Parameter

##### Basic Description
- **Type**: `bool`
- **Default Value**: `False`
- **Function**: Controls log output level and detail

##### Log Configuration Comparison

| Mode | debug=False (default) | debug=True |
|------|-------------------|------------|
| **Log Level** | ERROR | DEBUG |
| **Log Format** | `%(levelname)s - %(message)s` | `%(asctime)s - %(name)s - %(levelname)s - %(message)s` |
| **Display Content** | Only error messages | All debug information |


### 📁 Supported JSON Configuration Formats

#### Standard MCP Configuration Format

MCPStore uses `standard MCP configuration format`, supporting both `URL-based` and `command-based` service configurations:

```json
{
  "mcpServers": {
    "mcpstore-wiki": {
      "url": "http://mcpstore.wiki/mcp"
    },
    "howtocook": {
      "command": "npx",
      "args": [
        "-y",
        "howtocook-mcp"
      ]
    }
  }
}
```


#### Scenario: Multi-tenant Configuration 🏢

```python
# Tenant A configuration
tenant_a_store = MCPStore.setup_store(
    mcp_config_file="tenant_a_mcp.json",
    debug=False
)

# Tenant B configuration
tenant_b_store = MCPStore.setup_store(
    mcp_config_file="tenant_b_mcp.json",
    debug=False
)

# Provide isolated services for different tenants
tenant_a_tools = tenant_a_store.for_store().list_tools()
tenant_b_tools = tenant_b_store.for_store().list_tools()
```


## Powerful Service Registration `add_service` 💪

The core of `mcpstore` is `store`. Simply initialize a `store` through `setup_store()`, and you can register `any number` of services supporting all `MCP protocols` on this `store`. No need to worry about the `lifecycle and maintenance` of individual mcp services, no need to worry about `CRUD operations` for mcp services - `store` will `take full responsibility` for the lifecycle maintenance of these services.

When you need to integrate these services into langchain Agent, calling `store.for_store().to_langchain_tools()` provides `one-click conversion` to a tool set fully compatible with langchain `Tool` structure, convenient for direct use or `seamless integration` with existing tools.

Or you can directly use the `store.for_store().use_tool()` method to `customize your desired tool calls` 🎯.

### Service Registration Methods

All services added through `add_service` have their configurations `uniformly managed` and can optionally be persisted to the `mcp.json` file registered during setup_store. `Deduplication and updates` are `automatically handled` by mcpstore ⚙️.


### Basic Syntax
```python
store = MCPStore.setup_store()
store.for_store().add_service(config)
```

### Supported Registration Methods

#### 1. 🔄 Full Registration (No Parameters)
Register all services in the `mcp.json` configuration file.

```python
store.for_store().add_service()
```
Without passing any parameters, `add_service` will `automatically find and load` the `mcp.json` file in the project root directory, which is `compatible with mainstream formats`.

**Use Cases**:
- `One-time registration` of all pre-configured services during project initialization
- `Reload` all service configurations

---

#### 2. 🌐 URL-based Registration
Add remote MCP services through URL.

```python
store.for_store().add_service({
    "name": "mcpstore-wiki",
    "url": "http://mcpstore.wiki/mcp",
    "transport": "streamable-http"
})
```

**Fields**:
- `name`: Service name
- `url`: Service URL
- `transport`: Optional field, can `automatically infer` transport protocol (`streamable-http`, `sse`)

---

#### 3. 💻 Local Command Registration
Start local MCP service processes.

```python
# Python service
store.for_store().add_service({
    "name": "local_assistant",
    "command": "python",
    "args": ["./assistant_server.py"],
    "env": {"DEBUG": "true", "API_KEY": "your_key"},
    "working_dir": "/path/to/service"
})

# Node.js service
store.for_store().add_service({
    "name": "node_service",
    "command": "node",
    "args": ["server.js", "--port", "8080"],
    "env": {"NODE_ENV": "production"}
})

# Executable file
store.for_store().add_service({
    "name": "binary_service",
    "command": "./mcp_server",
    "args": ["--config", "config.json"]
})
```

**Required Fields**:
- `name`: Service name
- `command`: Execution command

**Optional Fields**:
- `args`: Command parameter list
- `env`: Environment variable dictionary
- `working_dir`: Working directory

---

#### 4. 📄 MCPConfig Dictionary Registration
Use standard MCP configuration format.

```python
store.for_store().add_service({
  "mcpServers": {
    "mcpstore-wiki": {
      "url": "http://mcpstore.wiki/mcp"
    },
    "howtocook": {
      "command": "npx",
      "args": [
        "-y",
        "howtocook-mcp"
      ]
    }
  }
})
```

---

#### 5. 📝 Service Name List Registration
Register specific services from existing configuration.

```python
# Register specified services
store.for_store().add_service(['mcpstore-wiki', 'howtocook'])

# Register single service
store.for_store().add_service(['howtocook'])
```

**Prerequisites**: Services must be defined in the `mcp.json` configuration file 📋.

---

#### 6. 📁 JSON File Registration
Read configuration from external JSON files.

```python
# Read configuration from file
store.for_store().add_service(json_file="./demo_config.json")

# Specify both config and json_file (json_file takes priority)
store.for_store().add_service(
    config={"name": "backup"},
    json_file="./demo_config.json"  # This will be used ⚡
)
```

**JSON File Format Examples**:
```json
{
  "mcpServers": {
    "mcpstore-wiki": {
      "url": "http://mcpstore.wiki/mcp"
    },
    "howtocook": {
      "command": "npx",
      "args": [
        "-y",
        "howtocook-mcp"
      ]
    }
  }
}
```
And other formats supported by `add_service` 📝

``` json
{
    "name": "mcpstore-wiki",
    "url": "http://mcpstore.wiki/mcp"
}
```
