Inform Growth — Beacon Software demo MCP

A standalone MCP server that demonstrates Inform Growth's Camber Core platform using a fictional B2B SaaS company (Beacon Software, ~$15M ARR, ~80 employees). All data is synthetic; all tool shapes are real.

What it does

Connect any MCP-capable AI client. The server exposes ~20 tools across five categories — crm_*, marketing_*, billing_*, support_*, ops_* — plus three orchestration tools for a guided 5-step walkthrough.

A prospect plays the CEO of Beacon Software, runs a few prompts against their agent, and experiences the cross-system rollups, anomaly detection, and workflow capture they'd get from a real Camber Core deployment.

Connect from an AI client

After the server is live (e.g. on Railway), point your client at the URL.

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "inform-demo": {
      "url": "https://<your-railway-host>/mcp"
    }
  }
}

Claude Code (CLI)

claude mcp add inform-demo --transport http https://<your-railway-host>/mcp

One-line bootstrap prompt

Connect to the Inform Growth demo MCP at <URL>. Read the welcome://demo resource, then call start_demo() and walk me through the 5 steps as the CEO of Beacon Software.

Run locally

pip install ".[dev]"

# stdio (Claude Code / Inspector)
python server.py

# HTTP
MCP_TRANSPORT=streamable-http python server.py
# server on http://localhost:8000/mcp

Regenerate synthetic data

python scripts/generate_beacon.py
# writes data/beacon.json (deterministic — seed=42)

Seeded patterns the walkthrough depends on:

• Companies 7, 23, 41 → expansion-risk (high MRR growth + tickets + low CSAT)

• Deals 102, 118 → stalling (no activity 60+ days)

• Campaign 14 → surprising attribution win

• Project 23 → at-risk, blocking revenue recognition

Internal analytics

Every meaningful event emits a JSON line to stdout. Railway aggregates these in the service log view. To get a funnel out of them:

railway logs --service demo-mcp \
  | grep '"event":' \
  | jq -s 'group_by(.event) | map({event: .[0].event, count: length})'

Event types:

Deploy to Railway

1. Create a new Railway service pointed at this repo (Inform-Growth/inform-demo-mcp, main branch)

2. Railway auto-detects the Dockerfile at the repo root. No further config needed.

3. Optional env overrides:

   • MCP_TRANSPORT (default streamable-http)

   • MCP_SERVER_NAME (default inform-demo-mcp)

   • PORT (Railway injects this; the server binds to it automatically)

   • ALLOWED_HOSTS — comma-separated hostnames that pass DNS-rebinding protection. Supports host:* for any port. Default: unset, which disables the check (appropriate for a public demo). Set to the Railway hostname (e.g. inform-demo-mcp.up.railway.app) to lock it down.

4. Public networking — toggle on in Railway so prospects can connect

After deploy, the URL is https://<service>.up.railway.app/mcp.

Design notes

• No auth, no init gate — public by design. Locked in inform-notes/notes/track-a2-v0-scope.md D5.

• Per-connection session state — start_demo returns a session_id; client passes it to next_step / save_workflow. State is in-memory and lost on reconnect (D6).

• save_workflow persists only for the duration of the connection. Honest about the demo nature (D4).

• 20 tools, 5 categories — generic prefixes so prospects don't anchor on "we use a different tool" (D1).

• Deterministic data — Faker.seed(42) plus surgical pattern injection. Anyone who regenerates gets identical output (D2).

• Hosting — Railway, deployed from this repo's main branch. D7's Calendly placeholder lives in beacon/orchestration.py.
