Rillsoft Project MCP server

Deutsch

Rillsoft AI is the AI gateway to Rillsoft Project, the specialist solution for multi-project resource and capacity planning in mid-sized industrial companies: an MCP server built into Rillsoft Project 10, on top of its scheduling engine – not on top of a task list.

The server runs inside the visible, running Rillsoft Project on Windows and exposes the open project to an AI assistant or a script over the Model Context Protocol: project structure and schedule, roles, people, teams, machines and material, candidate search and staffing assistants, capacity analysis, baselines and plan/actual comparison, progress and status date, the resource pool, undo and redo.

This repository contains documentation and client configuration only. The server is part of the Rillsoft Project 10 desktop application; there is no package to install and no hosted endpoint.

What it is not

• Not a task, to-do or Kanban tool, and not a platform for chat, wiki or team collaboration.
• Not a standalone AI product or chat plug-in, but AI access to Rillsoft Project as a whole – product, editions and pricing are on www.rillsoft.com.
• Not an AI that schedules on its own: Rillsoft Project calculates dates, workload and the critical path; the AI reads the result.
• Not a cloud service: the server is reachable on 127.0.0.1 only, inside the open Rillsoft Project. Rillsoft sends nothing; what your AI client sends is governed by its provider's privacy policy.
• Not a team server: there is no remote access.
• Not a portfolio editor: portfolios can be opened and evaluated, but not changed.

Set up

1. Enable the server. In Rillsoft Project open Settings → MCP server, set the active switch and leave read-only mode switched on for now. Alternatively start RillPrj.exe /mcp (port 3928) or RillPrj.exe /mcp:8123 (another port) for one session. Check: the status line shows "running on port 3928".

2. Connect your AI client with clients/generic.json:

   json

   {
     "mcpServers": {
       "rillsoft-project": {
         "type": "http",
         "url": "http://127.0.0.1:3928/mcp"
       }
     }
   }
   

   With an API key set in the settings, use clients/generic-api-key.json (Authorization: Bearer <KEY>). Ready-made entries per client:

   Client	File	Where it goes	Verified
   Claude Code	claude-code.mcp.json	.mcp.json in the project folder, or claude mcp add --transport http rillsoft-project http://127.0.0.1:3928/mcp	12 Oct 2026, 2.1.296
   Claude Desktop	claude-desktop.json	claude_desktop_config.json (Settings → Developer → Edit Config); bridge mcp-remote needs Node.js	12 Oct 2026, 2.31226
   Codex	codex.toml	~/.codex/config.toml, or codex mcp add rillsoft-project --url http://127.0.0.1:3928/mcp	12 Oct 2026, CLI 0.162
   VS Code	vscode.mcp.json	.vscode/mcp.json	12 Oct 2026, 1.117
   Cursor	cursor.mcp.json	~/.cursor/mcp.json	per vendor documentation

   Claude Code and VS Code need Rillsoft Project 10 build 10.0.625 or later. Any other client that speaks MCP over Streamable HTTP uses the address above; its documentation names the field names. Check: the client lists the server's tools – in read-only mode only the read-only ones. /mcp is exact, /mcp/ is a 404.

3. Ask the first question, for example: Summarize the current project status: dates, progress, open conflicts, in five paragraphs. Shipped industry examples with synthetic data let you try it without your own projects.

Every mutating call is one ordinary undo step in Rillsoft Project – you take it back with Ctrl+Z like any of your own edits.

Tool catalogue and contract

Tool names carry the prefix rillsoft_ and are English in every language build; arguments, result fields, enum values and error codes are stable, messages follow the language of the running Rillsoft Project. How tools/list, schemas, errors, undo, read-only mode and sessions work: Developers: the MCP server contract.

The complete tool catalogue – 118 tools of Rillsoft Project 10.0.624.0 with title, access class, parameters and description – is in TOOLS.md. It is generated from tools/list of the running program by scripts/generate_tools.py, never edited by hand; the raw result, including the output schemas, is in tools-list.json.
