developh

Free website audits through Developh's MCP server (Streamable HTTP at https://www.developh.co/mcp, no sign-in, no keys in config): Google PageSpeed Insights on mobile for any public website, with the four Lighthouse scores, real-visitor Core Web Vitals when Google has them, the failing audits that weigh most, missing security headers and page weight. Bundles the website-audit skill, which turns the report into a ranked fix list for the site's stack. Agent Plugins v1 package (plugin.json + mcp.json + skills/), configuration only. Disclosure: hosted-only connector with no local code; every tool call goes to www.developh.co, and run_website_audit passes the address it is given to Google PageSpeed Insights. Audits are not stored. Three tools are annotated read-only (run_website_audit, studio_info, list_case_studies). request_contact writes: it sends a project inquiry with the name, email and message the person gives, which Developh stores and records in its analytics, and emails them a confirmation. The package marks the server untrusted, so Hermes asks before request_contact runs and refuses it in unattended runs. The tool set is served by the remote server at runtime and is not covered by the pinned sha.

website-audit

Ask your agent "why is my website slow?" and it runs a Google PageSpeed Insights audit (Lighthouse, mobile) of any
public website, then answers with a ranked list of fixes for your stack instead of a raw report: the four scores,
Core Web Vitals from real visitors when Google has them, the failing audits that weigh most, missing security headers
and page weight.

The audit runs on Developh's free MCP server at https://www.developh.co/mcp. No sign-up, no API key.

Install

Any agent that reads skills (Claude Code, Codex, Cursor, Gemini CLI and others):

npx skills add developh/skills

The skill works without the MCP server: it calls the same tool over HTTP with curl. To give the agent the tools
directly, add the server too.

Claude Code, as a plugin (skill and MCP server together):

claude plugin marketplace add Developh/skills
claude plugin install developh@developh

Claude Code, only the MCP server:

claude mcp add --transport http developh https://www.developh.co/mcp

Cursor: the repository is a Cursor plugin too (.cursor-plugin/plugin.json).

Hermes Agent: the repository root is an Agent Plugins v1 package (plugin.json, mcp.json, skills/). Pinned
install: hermes plugins install Developh/skills --ref <commit>.

Tools on the MCP server

| Tool | What it does | Writes anything |
|---|---|---|
| run_website_audit | PageSpeed Insights mobile audit of a public website, 10 to 90 s | No |
| studio_info | Facts about Developh: services, sectors, timelines, contact | No |
| list_case_studies | Developh's published client work, by sector or service | No |
| request_contact | Sends a project inquiry to Developh on the person's behalf | Yes, see below |

What it sends where

  • Every tool call goes to www.developh.co. run_website_audit passes the address you give it to Google PageSpeed
    Insights. Developh does not store the audits.
  • request_contact is the only tool that writes: it creates an inquiry with the name, email and message the person
    gave, which Developh stores with its other inquiries and records in its analytics, and they get a confirmation
    email. The skill tells the agent to use it only when the person asked, with
    their own details, after showing them the message. The Hermes package marks the server untrusted, so Hermes asks
    before it runs and refuses it in unattended runs.
  • About 20 audits per 10 minutes per client and 5 inquiries per hour.
  • Privacy policy: https://www.developh.co/en/privacy-policy
