Morph MCP

Supercharge your coding agent. One MCP with two specialized tools for faster edits and smarter retrieval.

Tools

| Tool | What it does |
|------|-------------|
| edit_file | Apply code changes at 10,500+ tokens/sec with 98% accuracy |
| warpgrep_codebase_search | Sub-agent that runs parallel grep/read operations to find relevant code |

Both tools are enabled by default.

Quick Start

$3

``bash
claude mcp add morph-mcp -e MORPH_API_KEY=sk-xxx -- npx -y @morphllm/morphmcp
`

$3

Add to .cursor/mcp.json:

`json
{
"mcpServers": {
"morph-mcp": {
"command": "npx",
"args": ["-y", "@morphllm/morphmcp"],
"env": {
"MORPH_API_KEY": "sk-xxx",
"ENABLED_TOOLS": "warpgrep_codebase_search"
}
}
}
}
`

$3

Add to .vscode/mcp.json:

`json
{
"mcp": {
"servers": {
"morph-mcp": {
"command": "npx",
"args": ["-y", "@morphllm/morphmcp"],
"env": {
"MORPH_API_KEY": "sk-xxx",
"ENABLED_TOOLS": "edit_file,warpgrep_codebase_search"
}
}
}
}
}
`

How the Tools Work

$3

Applies code edits using Morph's Fast Apply model. The agent sends partial code with // ... existing code ... placeholders, and Fast Apply merges it into the full file.

`
Input:
path: "src/api.ts"
code_edit: |
export async function fetchData(endpoint: string) {
// ... existing code ...
const response = await fetch(endpoint, {
headers,
timeout: 5000 // added timeout
});
// ... existing code ...
}
instruction: "Add 5 second timeout to fetch call"

Output: Git-style unified diff showing exactly what changed
`

$3

A search sub-agent that explores your codebase autonomously. Give it a problem and it runs multiple grep/read operations to locate relevant files and line ranges.

`
Input:
search_string: "Find where authentication tokens are validated"
repo_path: "/Users/me/project"

Output: List of files with specific line ranges + actual code content
`

Configuration

| Variable | Description | Default |
