Claude Plugin Publishing Guide: From Validation to Listing, the Complete Workflow

Meta Description

A complete guide to publishing Claude plugins: understand the developer portal's validation process, security scan requirements, directory publishing steps, and how to use 90-day usage analytics to optimize your plugin, plus the paid plan prerequisite.

Claude's plugin ecosystem is opening its doors to developers, but getting a plugin onto the directory is not as simple as clicking "submit." The official developer portal lays out a clear path: validate the plugin, clear the security scan, complete publishing, and review 90 days of usage analytics. The entire process has one prerequisite — a paid plan is required.

For developers hoping to reach users through Claude, this workflow determines whether a plugin gets seen, trusted, and continuously used. Below we break down what each stage actually means and where the pitfalls lie.

Step One: Validate the Plugin, Don't Just Ship It

The first gate in the publishing process is plugin validation. The official wording is "validate it," which means confirming before submission that your plugin's structure, configuration, and dependencies meet directory requirements.

Many plugins get rejected for unremarkable reasons: missing manifest fields, permission declarations that exceed actual usage, and dependency versions that don't match the runtime. Validation is essentially a self-check that keeps obviously non-compliant issues from reaching submission. Developers should treat validation as part of the publishing process, not a formality.

From an engineering perspective, passing validation only means the plugin "can be installed" — not that it "runs securely." That leads to the next, more critical gate.

A plugin manifest is the metadata file describing a plugin's identity and capability boundaries, typically including the name, version, entry file, required permissions, and dependency declarations. The directory review system uses it to determine whether a plugin conforms to the spec; missing fields or declarations that don't match actual behavior will cause validation to fail.

The Principle of Least Privilege requires that a plugin request only the permissions necessary to accomplish its core function. For example, a plugin that only does text formatting should not request network access or permission to read the user's conversation history. Over-requesting permissions not only triggers security scan alerts but also reduces users' willingness to install.

Step Two: The Security Scan Is the Real Gate

The guide explicitly mentions "clear the security scan," and the security scan carries the most weight in the publishing process. Within the Claude environment, plugins come into contact with user input, external interfaces, and even sensitive context. Any unauthorized access, data exfiltration, or injection risk will be exposed at this stage.

The security scan typically focuses on: whether the permissions a plugin requests match its functionality, whether there are undeclared network calls, and whether the handling of user data is transparent. Before listing, developers should proactively narrow their permission scope and request only the minimal set their functionality requires; they should clearly document external requests to avoid being flagged as risky during the scan due to "unclear purpose."

There are no shortcuts here. Passing the scan means the plugin can be trusted enough to enter the directory, and it directly affects whether users are willing to install it afterward.

Common categories of security risk include: unauthorized access (a plugin reads data beyond what its functionality requires), data exfiltration (sending user input to an undeclared third-party service), and injection attacks (executing malicious code through a plugin's input channel). The security scan performs static analysis of code and configuration and matches and checks network request targets.

Developers can reduce the likelihood of being flagged as risky by clearly declaring in documentation the purpose and target domain of each external request, using the platform's recommended SDK or interface wrappers, and avoiding dynamically concatenating request URLs. Self-checking locally or in a test environment by simulating the scan rules in advance can also significantly reduce the number of resubmissions.

Step Three: Publishing and Directory Visibility

Only after validation and the security scan are complete does a plugin enter the publishing stage. Publishing means the plugin appears in the Claude directory as an item users can search for and install.

The directory itself is a distribution channel. How a plugin is presented in the directory — its name, description, and feature explanation — determines whether users click. Developers should write the description as a direct answer to "what problem does this solve" rather than piling on technical jargon. Entries in the directory follow the same logic as a typical app store: clear positioning drives more installs than a long list of features.

Publishing is not the end. The guide also mentions that you can review 90 days of usage analytics — an often overlooked but highly valuable capability.

Step Four: Iterate with 90-Day Usage Analytics

After publishing, developers can review 90 days of usage data. This window is long enough to observe a plugin's real usage curve: which features are called frequently, where users drop off mid-task, and what retention looks like after installation.

Comparing analytics data against the assumptions you made at launch is the foundation for continuous improvement. A common mistake is focusing only on install counts after launch while ignoring depth of usage. The 90-day data window provides a relatively complete observation period, enough to support an evidence-based feature adjustment.

Usage analytics typically include metrics such as call counts, active user numbers, feature path distribution, error rates, and retention curves. Compared with install counts alone, call depth and retention rate better reflect whether a plugin truly solves users' problems.

It's advisable to define quantifiable success metrics before launch (for example, weekly active call counts or task completion rate) and compare data weekly after launch. If a feature's call frequency keeps declining, consider simplifying its entry point or adjusting its description; if the error rate is concentrated in a particular step, prioritize fixing that path. After the 90-day window ends, you can use the accumulated data to set feature priorities for the next version.

The Paid Plan: An Underrated Prerequisite

The guide contains a sentence that's easy to skip: a paid plan is required. This means plugin publishing is not open to all developers — the paid plan is the ticket into the directory ecosystem.

The practical impact of this restriction is that it filters out low-quality bulk submissions and pushes developers to take validation and security more seriously before listing. For teams that are serious about building plugins, this isn't an obstacle — it's the baseline for ecosystem quality.

The Signal Behind the Publishing Process

Looking at the four stages together, the Claude directory's publishing path reflects the platform's stance on plugin quality: validation ensures usability, the security scan ensures trustworthiness, publishing ensures visibility, and analytics ensure iterability. If developers focus only on the "submit" action, they'll easily get stuck repeatedly at the security scan or validation stage.

For teams preparing to list a plugin, the sensible approach is to move validation and security checks earlier into the development stage, polish the directory description as if it were product copy, and connect usage analytics as soon as possible after publishing. That's when a plugin's journey in the Claude directory truly begins.

One-line Summary

Listing a Claude plugin requires validation, a security scan, publishing, and 90-day analytics review — with a paid plan as the prerequisite.

Paragraph Summary

The Claude plugin directory publishing process has four stages: validating plugin structural compliance, passing the security scan, officially publishing to gain directory visibility, and reviewing 90-day usage analytics after launch. Validation requires a complete manifest and permission declarations that match actual functionality; the security scan carries the most weight, focusing on least privilege, transparency of network calls, and compliant data handling. After publishing, the plugin enters the directory as a distribution channel, and the description should focus on the problem it solves. The 90-day analytics window is for observing depth of usage, not just install counts. The entire process requires a paid plan as a prerequisite, which serves to filter out low-quality submissions. Developers should move validation and security checks earlier into development and polish the directory description as product copy.
