Unreviewed plugin submission. This PR was generated automatically from a submission form and has not been reviewed by Cursor.

Adds third_party/pengju/, LitSynth by Pengju, LLC, as a remote MCP plugin.

• mcp.json stores the submitted hosted URL (https://litsynth.ai/api/mcp) under server key pengju; plugin.json references ./mcp.json (same layout as PitchBook in Add PitchBook third-party MCP plugin #796).
• Plugin README, one row in the root README integrations table, and one entry in .cursor-plugin/marketplace.json. .claude-plugin/marketplace.json is unchanged.
• node scripts/validate-plugins.mjs passes.

Submission

• Contact: Ryan Yan, Pengju, LLC, support@litsource.net
• Publisher handle: pengju
• Website: https://litsource.net
• plugin_url: https://litsynth.ai/api/mcp
• Listing targets: Grok Bot, Cursor

Logo
The submitted logo_url (https://litsynth.ai/favicon.svg) could not be fetched from the build VM (TLS connection reset). assets/logo.svg is the LitSynth mark from the publisher's own asset host, https://pengju-marketplace-assets.vercel.app/litsynth-marketplace.svg, which is listed there as the LitSynth logo. Please check it against the favicon on litsynth.ai.

Note for reviewers
An earlier, separate pengju submission for LitSource (https://litsource.net/mcp) was pushed to branch add-pengju-plugin but no PR was ever opened for it. This PR is for LitSynth only. If both products should be listed, one of them needs a different plugin name.
