Motif

Motif MCP server

One server, usable from Claude Code, Cursor, Claude Desktop, and any MCP host. A designer or researcher working in an agent environment can say "synthesise these transcripts" and get the same cited, critic-checked result the CLI gives. Every tool is a thin call into synth/engine.py; the loop, prompts, and config are shared with the CLI and the FigJam plugin, never duplicated.

Tools

Failure semantics: a missing verdict, an empty synthesis, an unparseable document, a run that does not exist, or turn ids none of which exist all return an MCP tool error. There is no empty success.

Progress: every engine progress line (each transcript ingested, each model call, each critic iteration) is sent twice: as an MCP log notification, which a host only receives if it has set a logging level, and as a progress notification, which a host receives if it passed a progress token (Claude Code does). stdout is the protocol; nothing else ever writes to it.

Install (local mode)

From PyPI, into any Python 3.10+ environment:

pip install "etot-motif[mcp]"

which motif-mcp # the server entry point; hosts need this absolute path

Or with no install step, if you have uv: the command is uvx --from "etot-motif[mcp]" motif-mcp. Installed this way the server uses the packaged config and writes run logs to ~/.motif/runs (override with MOTIF_RUNS_DIR).

From a Motif checkout:

git clone https://github.com/sleepycobalt/motif.git

cd motif python3 -m venv .venv && source .venv/bin/activate pip install -e ".[mcp]" echo "ANTHROPIC_API_KEY=your-key-here" > .env ls .venv/bin/motif-mcp # the server entry point

The server reads ANTHROPIC_API_KEY from the environment or the repo's .env, writes run logs to runs/ in the repo (override with MOTIF_RUNS_DIR), and uses config/synth.yaml, a symlink to the packaged synth/synth.yaml (override with MOTIF_CONFIG). Every host below needs the absolute path to .venv/bin/motif-mcp; hosts spawn servers without your shell's PATH.

Claude Code

claude mcp add motif -- /ABSOLUTE/PATH/TO/motif/.venv/bin/motif-mcp

Optionally install the skill so Claude Code knows the workflow (verify citations with receipts, mind contested insights, push to FigJam):

mkdir -p ~/.claude/skills/motif

cp /ABSOLUTE/PATH/TO/motif/surfaces/mcp/skills/motif/SKILL.md ~/.claude/skills/motif/SKILL.md

Then in a new Claude Code session:

/mcp                                   # motif should show as connected

synthesise ./data/raw/Dataset-2 with motif and open the report

Claude Code calls motif_synthesize, streams the engine's progress, and can then call motif_receipts to verify any citation or motif_board to push the run onto a FigJam board via Figma's MCP server.

Cursor

Add to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project):

{

"mcpServers": { "motif": { "command": "/ABSOLUTE/PATH/TO/motif/.venv/bin/motif-mcp", "env": { "ANTHROPIC_API_KEY": "your-key-here" } } } }

Restart Cursor; the five motif_* tools appear under MCP tools.

Claude Desktop

Open the config file (Claude menu → Settings → Developer → Edit Config), or edit it directly:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

{

"mcpServers": { "motif": { "command": "/ABSOLUTE/PATH/TO/motif/.venv/bin/motif-mcp", "env": { "ANTHROPIC_API_KEY": "your-key-here", "MOTIF_RUNS_DIR": "/ABSOLUTE/PATH/TO/motif/runs" } } } }

Quit and reopen Claude Desktop; the tools appear under the tools icon in the chat box. Claude Desktop cannot open files on your disk, so ask for the report markdown in the reply, or read it from the run directory.

Remote mode

Set MOTIF_REMOTE_URL and the same five tools forward to the hosted Motif service (surfaces/hosted/) instead of running the engine locally: no Python dependencies beyond the server itself, and the same results. Your ANTHROPIC_API_KEY is forwarded with each job and used for that job only. In remote mode a tool's run_id is the hosted job id, valid for an hour after the job finishes; motif_receipts, motif_board, and motif_runs_get take it. The hosted engine runs with the logger's redact=True: prompt and response bodies are stored as length + SHA-256, corpora are never snapshotted, and the job's uploads are deleted at expiry. MOTIF_REMOTE_TOKEN selects the paid tier, which is not switched on yet.

claude mcp add motif -e MOTIF_REMOTE_URL=https://motif-hosted.fly.dev -e ANTHROPIC_API_KEY=your-key-here -- motif-mcp

Board output through Figma's MCP server

motif_board returns a layout and scripts; it does not touch Figma. The host (Claude Code with Figma's MCP server authenticated) runs each script with use_figma against a FigJam board URL and reads the result back with get_figjam. Verified on a real board on 2026-09-04 (docs/exhibits/step-zero/, docs/exhibits/board-r5/).

Listing

listing.md holds the descriptions for directories that index MCP servers; server.json is the manifest for the official MCP registry (publish after the package is on PyPI).
