Daedalus MCP

Daedalus MCP is a local Model Context Protocol (MCP) server for creating and running specialized engineering agents per project or workspace.

It is designed for workspaces that may contain:

• a single backend service;
• several related microservices;
• a frontend + BFF + backend setup;
• a monorepo or folder with multiple related projects.

Daedalus scans the current workspace, detects the projects and their technologies, creates reusable agent templates, generates project-specific rules/knowledge, and lets you run sequential agent pipelines such as planning, rules validation, performance review, and architecture review.

Main idea

Given a workspace like:

workspace/
  catalog/
  data-mirror/
  vendors-bff/
  admin-ui/

Daedalus can detect stacks such as Java/Spring Boot or Angular and create:

workspace/
  .engineering-agents/
    workspace.agents.yaml

  catalog/
    agents.config.yaml
    agents/
      plan/
      rules/
      performance/
      architecture/

  admin-ui/
    agents.config.yaml
    agents/
      plan/
      rules/
      performance/
      architecture/

Reusable templates live inside this MCP project:

templates/
  java21-spring-boot-plan/
  typescript-angular-plan/
  project-rules-validator/
  performance-jvm/
  performance-web-node/
  architecture-microservice/
  architecture-frontend/

Daedalus does not overwrite existing files by default.

Available MCP prompts / slash commands

Daedalus also registers MCP prompts named daedalus and daedalus-init. In clients that expose MCP prompts as slash commands, you can use:

/daedalus init
/daedalus listProjects
/daedalus plan --group:java-all "agregar healthcheck estándar"
/daedalus review --group:java-all "revisar el diff actual"

If the client says the slash command does not exist, use natural language or the daedalus tool directly, for example: “Use Daedalus and run /daedalus init”. Slash command availability is controlled by the host client, not by the MCP server alone.

Available MCP tools

daedalus_init

Scans the current workspace and initializes agents.

Equivalent slash-style command:

/daedalus init

What it does:

1. Detects the current workspace from MCP roots or cwd.
2. Finds projects inside the workspace.
3. Detects language, framework, build tool, package manager and architecture.
4. Creates missing reusable templates.
5. Creates agents.config.yaml and agents/ inside each detected project.
6. Creates workspace groups like all, java-all, angular-all, etc.

Options:

{
  workspacePath?: string,
  force?: boolean,
  refreshProjectKnowledge?: boolean,
  refreshTemplates?: boolean,
  maxDepth?: number
}

daedalus_listProjects

Lists projects detected by the last init.

Slash-style command:

/daedalus listProjects

daedalus_listGroups

Lists generated project groups.

Slash-style command:

/daedalus listGroups

Examples of groups:

all
java-all
java21-spring-boot-all
spring-boot-all
angular-all
typescript-all

daedalus_run

Runs an agent pipeline over a group or selected projects.

Slash-style examples:

/daedalus plan --group:java-all "agregar healthcheck estándar"

/daedalus plan --group:angular-all "agregar healthcheck estándar"

/daedalus plan --group:all "agregar healthcheck estándar"

/daedalus plan --project [catalog,data-mirror,vendors-bff] "agregar healthcheck estándar"

The report includes the response from every agent for every selected project.

Default plan pipeline:

plan -> rules -> performance -> architecture

daedalus_review

Runs the code-review pipeline over a group or selected projects. It reviews code, diffs, files or change descriptions using language/framework best practices and project-specific rules.

Slash-style examples:

/daedalus review --group:java-all "revisar el diff actual"

/daedalus review --project [catalog,data-mirror] "revisar cambios de healthcheck"

Default review pipeline:

code-review -> rules -> performance -> architecture

daedalus

Convenience parser for slash-style commands.

Input example:

{
  "command": "/daedalus plan --group:java-all \"agregar healthcheck estándar\""
}

Legacy aliases agent and agent_init are also available, but /daedalus is preferred.

Installation from local checkout

1. Clone the repository

git clone https://github.com/daedalus/daedalus-mcp.git
cd daedalus-mcp

Replace the URL with the real repository URL if different.

2. Install dependencies

npm install

3. Build

npm run build

4. Link the local binary

npm link

This exposes:

daedalus-mcp

Verify:

which daedalus-mcp

If your MCP client does not inherit your shell PATH, use the absolute path returned by which daedalus-mcp.

Add to Codex

Edit:

~/.codex/config.toml

Add:

[mcp_servers.daedalus]
command = "daedalus-mcp"
startup_timeout_sec = 60

If Codex cannot find daedalus-mcp, use the absolute path:

[mcp_servers.daedalus]
command = "/absolute/path/to/daedalus-mcp"
startup_timeout_sec = 60

Restart Codex.

Claude Code slash command /daedalus

Claude Code slash commands are client-side prompt files. If /daedalus is not recognized even though the MCP server is running, create this user-level command:

mkdir -p ~/.claude/commands
cat > ~/.claude/commands/daedalus.md <<'EOF'
---
description: Run Daedalus MCP commands
allowed-tools: mcp__daedalus__daedalus, mcp__daedalus__daedalus_init, mcp__daedalus__daedalus_listProjects, mcp__daedalus__daedalus_listGroups, mcp__daedalus__daedalus_run
---

Use the Daedalus MCP server. Run the MCP tool `daedalus` with:

{ "command": "/daedalus $ARGUMENTS" }

If `$ARGUMENTS` is empty, use `/daedalus init`. Summarize the MCP result for the user.
EOF

Restart Claude Code after creating or changing this file. Then use:

/daedalus init
/daedalus listProjects
/daedalus plan --group:java-all "agregar healthcheck estándar"
/daedalus review --group:java-all "revisar el diff actual"

Add to Claude Desktop

Edit:

~/Library/Application Support/Claude/claude_desktop_config.json

Add the server inside mcpServers:

{
  "mcpServers": {
    "daedalus": {
      "command": "daedalus-mcp"
    }
  }
}

If Claude cannot find daedalus-mcp, use the absolute path:

{
  "mcpServers": {
    "daedalus": {
      "command": "/absolute/path/to/daedalus-mcp"
    }
  }
}

Restart Claude Desktop.

Prompt to install from another Codex/Claude chat

Once this project is published, you can open a new Codex or Claude chat and say something like:

Install the Daedalus MCP from https://github.com/daedalus/daedalus-mcp.
Clone it, run npm install, npm run build, npm link, and add it as an MCP server named daedalus using the daedalus-mcp command. Then restart or tell me to restart the client.

For Codex specifically:

Install the MCP server from https://github.com/daedalus/daedalus-mcp and add this to ~/.codex/config.toml:

[mcp_servers.daedalus]
command = "daedalus-mcp"
startup_timeout_sec = 60

For Claude Desktop specifically:

Install the MCP server from https://github.com/daedalus/daedalus-mcp and add it to ~/Library/Application Support/Claude/claude_desktop_config.json under mcpServers as:

"daedalus": {
  "command": "daedalus-mcp"
}

Typical usage

After adding the MCP server and restarting the client, open a chat in the target workspace and run:

Use Daedalus and run /daedalus init

Then inspect what was detected:

Use Daedalus and run /daedalus listProjects

Use Daedalus and run /daedalus listGroups

Run a plan for all Java projects:

Use Daedalus and run /daedalus plan --group:java-all "agregar healthcheck estándar"

Run a code review for all Java projects:

Use Daedalus and run /daedalus review --group:java-all "revisar el diff actual"

Run a plan for specific projects:

Use Daedalus and run /daedalus plan --project [catalog,data-mirror,vendors-bff] "agregar healthcheck estándar"

Notes

• Daedalus uses MCP roots/list when available to identify the workspace opened in the client.
• If roots are unavailable, it falls back to the process cwd.
• workspacePath can be provided manually as an override.
• Existing generated files are preserved by default. If a previous init generated stale project knowledge, rerun init with refreshProjectKnowledge: true to regenerate generated knowledge/general and knowledge/project files.
• Pipeline execution uses MCP sampling when the host supports it. Some hosts return MCP error -32601: Method not found for sampling; in that case Daedalus now catches it and returns a handoff report with the prepared agent prompts/context so the host assistant can execute the reasoning in its final response.
