LinkedIn Content Planner MCP

Enables AI agents to draft, format, and manage LinkedIn posts through a review pipeline, with human approval via a web UI before publication.

Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

// tools this server exposes25 tools

These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

create_post

Add a new post idea to the backlog.

list_posts

List posts, optionally filtered by state(s) and scheduled-date range. E.g. state=ready + scheduledBefore=<today> finds posts due to publish.

get_post

Get a single post by id.

update_post_content
str_replace_post_content
list_versions

List all versions of a post, oldest first.

get_version_diff

Get a line-level diff between two versions of a post.

revert_to_version

Create a new version copying an older version's content (history stays append-only).

set_post_state

Move a post to a new state. The server enforces the legal-transition graph: backlog<->todo<->in_progress->in_review, ready->posted, ready->in_progress. Entering in_review is allowed here; leaving in_review (to ready or back to in_progress) only happens via submit_review.

set_post_date

Set (or clear, with null) a post's scheduled publish date.

delete_post

Permanently delete a post and everything attached to it (all versions, comments, reviews, and attachment files). Irreversible — there is no undo. Use for genuinely unwanted posts (duplicates, abandoned ideas), not as a way to unpublish something already posted.

submit_review

Approve or request changes on a post that is in_review. Approving moves it to ready; requesting changes moves it back to in_progress and requires a body explaining what to fix.

list_reviews

List the review history (approve/request-changes decisions) for a post.

add_comment

Add a comment on a post version, optionally anchored to a text range and/or threaded as a reply.

list_comments
resolve_comment

Mark a comment resolved or unresolved.

render_preview
prepare_attachment_upload
attach_file
list_attachments

List attachments on a post (metadata only, not file bytes).

create_webhook
list_webhooks

List all registered webhooks.

update_webhook
delete_webhook

Permanently delete a webhook subscription and its delivery history.

list_webhook_deliveries

List delivery attempts for a webhook (success/failure, response status, error), newest first — useful for debugging why an agent didn't get triggered.

// known CVEs in dependencies2 critical4 high2 low

Tool annotations

2/25 tools have annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

25/25 tools missing one or more hints — create_post (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_posts (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_post (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +22 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

README present

No README found

Add a README.md describing the server and its tools.

License file

No license file

Add a LICENSE file (MIT, Apache-2.0, etc.).

Tool test coverage

Only 0/25 tools referenced in tests (0%)

Write tests that reference each tool by name so every tool has at least one test.

Production dependencies are patched

0 critical, 4 high severity in production deps — @fastify/multipart@9.0.1 (high), @modelcontextprotocol/sdk@1.10.2 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

Dev dependencies

2 critical/high in dev-only deps (does not ship to users)

Upgrade dev dependencies when convenient.

Domain consistency

npm scope @linkedin-planner doesn't match GitHub owner theonaai

Use the same org name across GitHub, npm, and your homepage so users can verify the publisher.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 8 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
