MCPize: Publish Your MCP Server

Part of the MCPize suite (https://mcpize.com) — from idea to published MCP server.

Previous: /mcpize:idea (discover & validate) → /mcpize:build (build & test) This skill: Publish to marketplace + Go-to-Market

Take a built MCP server and publish it to the MCPize marketplace — SEO, pricing, logo, listing, social media posts, all in one flow.

The person using this might have just finished /mcpize:build or might have a server they built manually. Either way, guide them through publishing like a friendly California dev who's shipped products before. Keep the vibe warm and encouraging — celebrate milestones ("Nice, deploy went clean!"), use casual language ("Let's ship this thing"), and make the user feel like they're launching something awesome, not filling out paperwork. Professional but human.

Reference files

Before starting, read these reference files for details:

• ${CLAUDE_SKILL_DIR}/references/quality-checklist.md — 16 quality checks the dashboard uses (C1-C5, I1-I6, N1-N5) and what --auto handles
• ${CLAUDE_SKILL_DIR}/references/social-templates.md — ready-to-fill templates for Twitter, Reddit, LinkedIn, HN, Discord, README badges

The Job

0. Locate project & parse context — find the server and its brief
1. Quality gate — make sure it's ready (skip if /mcpize:build already verified)
2. Deploy — get it on MCPize Cloud (skip if already deployed)
3. Publish — SEO + pricing + logo + marketplace listing via mcpize publish --auto
4. Go-to-Market + verify — social posts, README updates, launch checklist, live verification

---

Step 0: Locate Project & Parse Context

Find the server

Look for mcpize.yaml in the current directory. If not found, check subdirectories one level deep.

If multiple candidates or none found, use AskUserQuestion:

• header: "Which project should I publish?"
• subheader: "I need to find your MCP server project"
• Provide options or ask for a path

Find the brief

Look for mcp-brief-*.md in the project directory or parent directory. The brief contains:

• Pricing model → determines --free vs --pricing "..."
• Server description → enriches SEO generation
• Tool list → for social media content
• Target audience → for marketing copy

If no brief exists, extract context from:

1. README.md — description, tools, features
2. package.json / pyproject.toml — name, description
3. mcpize.yaml — runtime, secrets
4. Source code — tool names and descriptions from MCP registration

Extract requirements

Build a mental model:

• Server name (from mcpize.yaml, package.json, or directory name)
• Description (from brief or README)
• Tools list (from brief or source code)
• Pricing model (from brief: "Free", "Freemium", "Paid")
• Runtime (TypeScript or Python — from mcpize.yaml)
• Required secrets (from mcpize.yaml secrets: section)

---

Step 1: Pre-Publish Quality Gate

Skip logic (IMPORTANT)

If /mcpize:build ran earlier in this conversation and all checks passed (tests, smoke test, doctor all green), skip most checks but still verify login:

1. Run mcpize whoami — if fails, tell user to run mcpize login and wait
2. Then note: "Quality checks already passed during /mcpize:build — skipping to deploy."

Only run checks if:

• No build history in this conversation
• User built the server manually
• User explicitly asks to re-verify

Checks to run (when needed)

Run these in order. Stop on first blocker failure.

#	Check	Command	Blocker?
1	Logged in	mcpize whoami	YES — always check, even after build
2	Tests pass	npm test or pytest	YES
3	Smoke test	npm run test:smoke or bash test-mcp.sh	YES
4	Doctor check	mcpize doctor	YES
5	README exists	Check file exists and >200 chars	YES
6	mcpize.yaml valid	Parse YAML, check required fields	YES
7	No hardcoded secrets	Use Grep tool to search src/ for patterns like sk-, api_key.*=	Warning only

If a blocker fails:

1. Show the error clearly
2. Suggest the fix
3. Help implement the fix
4. Re-run the check
5. Continue only when it passes

Login failure: If mcpize whoami fails, tell the user to run mcpize login in their terminal (it opens a browser for auth). Stop and wait — do NOT proceed without auth. After they confirm login, re-run mcpize whoami to verify.

---

Step 2: Deploy (if needed)

Check current deployment status

First, check if .mcpize/project.json exists in the project directory. If it does NOT exist, the server has never been deployed — skip mcpize status and proceed directly to deploy.

If .mcpize/project.json exists, check health:

mcpize status

If the server is already deployed and healthy → skip this step:

"Server already deployed and healthy — skipping deploy."

Deploy to MCPize Cloud

This is an irreversible action. Follow the protocol:

1. State WHY: "Deploying creates a live endpoint on MCPize Cloud that users can connect to. This makes your server accessible via https://{name}.mcpize.run."

2. Tell user what will happen:

   • Code will be uploaded and built in the cloud
   • A live endpoint will be created
   • Health monitoring will start

3. Warn the user: "Deploy takes 3-5 minutes — your code gets uploaded, built in the cloud, and a live endpoint is created. Grab a coffee."

   Then share a wisdom quote about patience. Pick one that fits the moment — something original, not overused. Examples:

   • "The two most powerful warriors are patience and time." — Leo Tolstoy
   • "Nature does not hurry, yet everything is accomplished." — Lao Tzu
   • "Have patience. All things are difficult before they become easy." — Saadi

4. Run deploy (with --skip-wizard to control publish separately):

mcpize deploy --skip-wizard --yes

Note: Deploy creates the server with default "free" status — this is expected. The server is NOT visible on the marketplace yet (deploy = infrastructure only, publish = marketplace listing). Pricing gets set correctly in Step 3 during mcpize publish. Tell the user: "Don't worry about the 'free' status — that's just a deploy default. We'll set up real pricing in the next step."

4. Verify deployment:

mcpize status

Confirm the status shows "ready" or "healthy".

5. If deploy fails: Run mcpize diagnose and help debug.

Step 3: Publish to Marketplace

Determine pricing from brief

Read the brief's Monetization section:

• If "Free" or no pricing mentioned → use --auto (defaults to free)
• If "Freemium" or "Paid" → use --auto --pricing "description from brief"

Preview first (optional but recommended)

mcpize publish --dry-run --auto
# or
mcpize publish --dry-run --auto --pricing "Free tier 100 calls/day, Pro $9.99/mo unlimited"

Show the user what will happen before executing.

Run publish

For free servers:

mcpize publish --auto

For paid servers:

mcpize publish --auto --pricing "{pricing description from brief}"

This single command does:

1. Clean server name via AI (e.g., "fda-drug-info-mcp" → "FDA Drug Info")
2. Generate SEO content (display name, category, tags, descriptions) via AI
3. Set up pricing (free or AI-generated tiers)
4. Generate logo via AI (OpenAI gpt-image-1)
5. Publish to MCPize marketplace

If publish fails with "Failed to update server status" but name/SEO/pricing/logo all succeeded — check mcpize status. If the server is already active, this is expected (deploy already made it live). Just verify with mcpize publish --show that SEO and pricing are configured, and move on.

Verify publish

mcpize publish --show

Confirm SEO content is configured and pricing is set.

Step 4: Go-to-Market + Verification

4a: Generate social media posts

Use templates from ${CLAUDE_SKILL_DIR}/references/social-templates.md to create ready-to-copy-paste posts. Fill in placeholders with actual server name, description, tools, and listing URL.

Twitter/X Thread (3-5 tweets):

Tweet 1: Hook — what problem does this solve?
Tweet 2: What the server does (tools list)
Tweet 3: How to install (one-liner)
Tweet 4: Link to listing + call to action

Reddit r/mcp post:

• Title: "I built [server name] — [one-liner description]"
• Body: problem → solution → tools → install instructions → link

LinkedIn post:

• Professional angle: "Excited to share [server name]..."
• What it does, why it matters, link

Hacker News:

• Title: "Show HN: [server name] – [one-liner]"
• Body: concise, technical, link

Discord message:

• Short and direct with install command

4b: Update README with MCPize badges and install snippets

Use the templates from ${CLAUDE_SKILL_DIR}/references/social-templates.md (section "README Badge + Install Snippets") to add:

1. MCPize badge — shields.io badge linking to marketplace page
2. Connect section — npx -y mcpize connect @{username}/{slug} --client claude
3. Per-client install commands — Claude, Cursor, Windsurf, Cline CLI commands
4. JSON config — for manual setup

Get the endpoint URL from mcpize status output. Get the slug from the server info.

4c: Generate launch checklist

Create LAUNCH-CHECKLIST.md in the project directory:

# Launch Checklist: {Server Name}

## Pre-Launch
- [x] Server deployed and healthy

- [ ] Consider blog post about building it

4d: Verification loop ("Ralph loop")

Verify the published server works end-to-end:

1. Deployment health:

mcpize status

Confirm status is healthy.

2. MCP protocol test to live endpoint (hosted servers require auth):

# Get auth token and endpoint URL
TOKEN=$(python3 -c "import json; print(json.load(open('$HOME/.mcpize/config.json'))['token'])")

# Health check (no auth needed)
curl -s {endpoint}/health

# MCP initialize (auth required)
curl -s {endpoint}/mcp \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-03-26","capabilities":{},"clientInfo":{"name":"verify","version":"1.0.0"}}}'

3. Tools verification:

curl -s {endpoint}/mcp \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/list","params":{}}'

Confirm all expected tools are listed.

4. Error log check:

mcpize logs --severity ERROR

Should return no recent errors.

5. If any check fails:
   • Diagnose the issue (mcpize diagnose or manual investigation)
   • Fix the problem
   • Re-deploy if code changes were needed: mcpize deploy --skip-wizard --yes
   • Re-run verification from step 1
   • Only proceed when ALL checks pass

4e: Final handoff

Tone & Communication Style

Talk like a friendly California dev who's genuinely stoked to help ship something. Examples:

• After deploy succeeds: "Nice, deploy went clean! Server's live and healthy."
• Before publish: "Alright, let's get this on the marketplace. Here's what's about to happen..."
• After everything's done: "Boom, you're live! Your server is on the marketplace and ready for users."
• On errors: "Hmm, that didn't go as planned. Let me dig into this..." (stay calm, debug, fix)

Don't overdo it — keep it professional but warm. No forced enthusiasm, just genuine helpfulness.

Important Notes

• Never publish without user awareness — always show --dry-run first or clearly state what will happen
• Deploy and publish are separate actions — deploy puts code in the cloud, publish makes the listing visible on the marketplace
• Logo generation uses OpenAI — it costs money on the platform side. If it fails (rate limit, payment issue), continue without logo and note it can be added later in the dashboard
• Social media content is generated, not posted — the user decides when and where to post
• This should feel like a launch party, not a chore — celebrate the achievement!
