FastMCP validates tool arguments with a pydantic model whose extra-field policy is 'ignore', so create_note(content=...) — a plausible near-miss for body=, primed by add_task_log's content — ran successfully, stored body: '', and left a record embedding/search cannot see. Two real notes were persisted body-less before the pattern was noticed; create_task only 'worked' because those calls happened to use the right name. StrictArgsFastMCP rejects any tool call carrying arguments the tool does not declare, before dispatch, with a did-you-mean hint when one is close and the declared list when none is. Applied at the dispatch seam so every tool gets the guarantee — an error the caller sees once beats data half-written forever. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Fabled Scribe
A self-hosted work system-of-record for software projects, built to be driven by Claude Code. Notes, tasks, issues, projects, milestones, rules, and stored processes — reachable from Claude via a built-in MCP endpoint and a bundled Claude Code plugin, with a clean web UI for humans. No in-app LLM; Claude is the sole assistant.
Features
Notes and tasks with a Markdown editor, sub-tasks, milestones, issues, and kanban project workspaces. Stored processes, an engineering rulebook system, and semantic search with proactive knowledge-injection into Claude's context. A knowledge graph, per-user/group sharing, and a built-in MCP server (/mcp) plus a bundled Claude Code plugin so Claude can record and recall your work directly.
Quick Start
Prerequisites: Docker and Docker Compose. No GPU or local model needed — Claude is the sole assistant, reached over MCP.
Download docker-compose.quickstart.yml from this repo, then:
# Optional but recommended — set a secret key
export SECRET_KEY=your-random-secret-here
docker compose -f docker-compose.quickstart.yml up -d
Open http://localhost:5000. The first user to register becomes admin. To connect Claude, create an API key under Settings → API Keys and install the Claude Code plugin — see API Keys & MCP.
Development: To build from source, see Development.
