# Cosense MCP Server
A MCP server for [Cosense](https://cosen.se).
## Tools
The following tools are available for interacting with Cosense pages:
- `get_page`: Retrieves a page with the specified title
- `list_pages`: Lists available pages in the resources
- `search_pages`: Searches for pages containing the specified query string
- `insert_lines`: Inserts text after a specified line in a page
## Installation
### Prerequisites
Set the following environment variables:
- `COSENSE_PROJECT_NAME` — your Cosense project name.
- `COSENSE_SID` — session cookie used for authentication. Required for writing pages and reading private pages. Treat this like a secret. See https://scrapbox.io/scrapboxlab/connect.sid for more details.

> **Note**: After clicking the button, replace `your_project_name` and `your_sid` with your actual values in the configuration. For manual setup, you can also edit [`.vscode/mcp.json`](.vscode/mcp.json) directly.
### For Claude Desktop Users
Add one of the following configurations to your `claude_desktop_config.json`:
#### Using pnpm
```json
{
"mcpServers": {
"cosense-mcp-server": {
"command": "pnpm",
"args": ["-s", "dlx", "@yosider/cosense-mcp-server"],
"env": {
"COSENSE_PROJECT_NAME": "your_project_name",
"COSENSE_SID": "your_sid"
}
}
}
}
```
#### Using yarn
```json
{
"mcpServers": {
"cosense-mcp-server": {
"command": "yarn",
"args": ["dlx", "-q", "@yosider/cosense-mcp-server"],
"env": {
"COSENSE_PROJECT_NAME": "your_project_name",
"COSENSE_SID": "your_sid"
}
}
}
}
```
#### Using npx
This package depends on JSR-hosted packages. `npx` requires adding the JSR registry to `~/.npmrc` first.
**Step 1: Add JSR registry to `~/.npmrc`**
Linux/macOS:
```bash
echo "@jsr:registry=https://npm.jsr.io" >> ~/.npmrc
```
Windows (PowerShell):
```powershell
echo "@jsr:registry=https://npm.jsr.io" >> $env:USERPROFILE\\.npmrc
```
**Step 2: Add configuration**
```json
{
"mcpServers": {
"cosense-mcp-server": {
"command": "npx",
"args": ["-y", "@yosider/cosense-mcp-server"],
"env": {
"COSENSE_PROJECT_NAME": "your_project_name",
"COSENSE_SID": "your_sid"
}
}
}
}
```
## Development
### Running from Source
If you prefer to run the server from a local copy of this repository, build it first:
```bash
git clone https://github.com/yosider/cosense-mcp-server.git
cd cosense-mcp-server
pnpm install
pnpm run build
```
Then configure your MCP client to use the local build:
```json
{
"mcpServers": {
"cosense-mcp-server": {
"command": "node",
"args": ["/path/to/cosense-mcp-server/build/index.js"],
"env": {
"COSENSE_PROJECT_NAME": "your_project_name",
"COSENSE_SID": "your_sid"
}
}
}
}
```
## Debugging
Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the [MCP Inspector](https://github.com/modelcontextprotocol/inspector), which is available as a package script:
```bash
pnpm run inspect
```
The Inspector will provide a URL to access debugging tools in your browser.
