MCP server for DAG-based workflow execution with YAML definitions and LLM collaboration
MCP server for DAG-based workflow execution with YAML definitions and LLM collaboration. The workflows mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 2 defined tools rather than through you.
Run YAML workflows as MCP tools so agents can automate real tasks with one server.
Everything the assistant can do here goes through one of these:
Prerequisites — The Prerequisites tool exposed by this serverConfiguration — The Configuration tool exposed by this serverYou will need 8 environment variables: WORKFLOWS_TEMPLATE_PATHS, WORKFLOWS_LOG_LEVEL, WORKFLOW_SECRET_API_KEY, MEMORY_DB_HOST, MEMORY_DB_PORT, MEMORY_DB_NAME, MEMORY_DB_USER, MEMORY_DB_PASSWORD. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
CREATE DATABASE rights on the admin database (typically postgres) if auto-create is enabled, or a pre-existing database that the user can connect to.The server ships on PyPI as workflows-mcp, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Among the AI and media services options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Workflows's toolset — Prerequisites, Configuration — is a fair guide to whether it matches your workflow.
This entry was verified against Workflows's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

If installed with `pip`:
```json
{
"mcpServers": {
"workflows": {
"command": "workflows-mcp",
"env": {
"WORKFLOWS_TEMPLATE_PATHS": "/path/to/your/workflows",
"WORKFLOWS_LOG_LEVEL": "INFO",
"WORKFLOW_SECRET_API_KEY": "your-secret-value"
}
}
}
}Configuration as documented by the project. Restart the client after saving.
