eventgraph-mcp

An MCP server that lets an agent read, check and write an eventgraph model without shelling out to the CLI.

{
  "mcpServers": {
    "eventgraph": {
      "command": "npx",
      "args": ["-y", "eventgraph-mcp"]
    }
  }
}

Reading: eventgraph_query, eventgraph_get_node, eventgraph_list_contexts, eventgraph_impact, eventgraph_slice, eventgraph_lifecycle.

Asking what is wrong: eventgraph_validate for shape, eventgraph_check for completeness — the one an agent should loop on, since it answers "what is missing" rather than "is this legal".

Writing: eventgraph_add_node, eventgraph_add_edge, eventgraph_remove_node. Whether these apply directly or propose a diff is the project's call, via agent.write in eventgraph.yaml.

Prefer eventgraph_slice over reading the whole graph — a large model does not fit a context window any better than it fits a screen.
