📚 Available Tools

1. get_codebase_files

Lists all files in a directory (respects .jympignore)

Example:

"List all files in /Users/me/my-app"

2. create_codebase_prompt

Combines all files into a single LLM prompt

Example:

"Create a codebase prompt for /Users/me/my-app with basic compression"

Parameters:

• directory: Path to your project

• compression: none or basic (optional)

3. create_prompt_from_files

Combines specific files into a prompt

Example:

"Combine src/index.ts and src/utils.ts from /Users/me/my-app"

Parameters:

• directory: Base directory path

• files: Array of file paths

⚙️ Configuration

Exclude Files with .jympignore

Create a .jympignore file in your project root:

node_modules
.git
dist
build
.env
*.log
.DS_Store
coverage/

The server automatically respects these exclusions.

Compression Modes

• none (default): Full file contents

• basic: Removes comments, blank lines, and compresses whitespace

🔧 Troubleshooting

"command not found: jymp-mcp-server" after installation

Problem: npm global bin directory not in PATH

Solution:

# Add npm global bin to your PATH
echo 'export PATH="$(npm bin -g):$PATH"' >> ~/.zshrc
source ~/.zshrc

# Then reinstall
npm install -g @mahendra189/jymp-mcp-server

# Find the path
which jymp-mcp-server

"Server not running" in Perplexity

Solutions:

1. Make sure you used the full path from which jymp-mcp-server

2. Test the command in Terminal first:

/your/full/path/to/jymp-mcp-server

3. Try removing and re-adding the connector

4. Double-check you copied the path correctly (no typos)

"Could not connect" in Claude Desktop

Solutions:

1. Completely quit Claude Desktop (Cmd+Q, not just close window)

2. Verify you used the correct full path from which jymp-mcp-server

3. Test in Terminal first to ensure it works

4. Check for typos in the config file

5. Make sure the JSON syntax is correct (commas, quotes, etc.)

Permission Errors on macOS

Claude may need disk access permissions:

1. Go to System Settings → Privacy & Security → Files and Folders

2. Grant Claude access to the directories you want to scan

Still Having Issues?

Run these diagnostic commands:

# Check Node.js is installed
node --version

# Check npm is working
npm --version

# List global packages
npm list -g --depth=0

# Find jymp-mcp-server path
which jymp-mcp-server

# Test it directly
$(which jymp-mcp-server)

If the last command works, then use that exact path in Perplexity/Claude config.
