Planable is the clearest starting point for an AI-assisted drafting and approval workflow. Buffer is a strong candidate when you want documented tools that can move from a conversation to a scheduled or immediately published post. Hootsuite deserves a place on the shortlist when the job also includes customer care, listening or employee advocacy. All three now describe MCP support, but the actions exposed and the controls around them differ. Planable MCP, Buffer MCP, Hootsuite MCP.
The useful question is what you want the assistant to finish. Preparing three drafts for review is a different job from publishing them, and neither establishes that someone has answered the comments afterward. Decide which of those responsibilities you intend to delegate before choosing the connector.
The three-way capability comparison
Scroll sideways to compare every column.
| Requirement | Planable | Buffer | Hootsuite |
|---|---|---|---|
| Draft creation and editing | Documented; AI-created posts remain drafts | Documented post tools with draft controls | Perch lists draft creation and updates |
| Scheduling or immediate publication | New content follows the normal approval and scheduling process | Explicit scheduling and immediate-publication modes | Perch advertises scheduling and immediate-publication examples |
| Approval actions | Available when the connected user has approval permission | Check the exposed action and account permissions; a Team approval feature alone does not prove an MCP approval action | Confirm the exact approval action and its product/plan entitlement |
| Media | Public-URL attachments and workspace library operations | Assets on post-creation and editing tools | Perch lists library and image/video publishing workflows |
| Analytics | Relevant workspace needs the Analytics add-on | Post metrics and aggregate metrics | Perch lists performance-data workflows |
| Access boundary | Paid plan; connected person's workspace permissions | API-key connection; plan-based request limits | Product-specific servers and account-linked permissions |

Pick the Hootsuite product that owns the work
Hootsuite names four MCP products: Perch for planning and publishing, Nest for inbox and customer care, Lumen for listening, and Parliament for advocacy. Its directory includes direct-publishing examples while its FAQ emphasizes human review and organizational control. Treat that as a reason to inspect the permitted action in your workspace, rather than assume that every connection either blocks or allows unattended publication. Hootsuite MCP products.
For a weekly publishing assistant, start the comparison with Perch. Adding listening to a caption request changes the data needed, and replying to a customer introduces another kind of external action. Keep each responsibility explicit. A useful workflow could gather campaign context, prepare content, then stop for an editor. An assistant that also handles customer conversations needs a separate decision about response authority and escalation.

A draft-first workflow for one small campaign
Consider a fictional workshop campaign with one LinkedIn post, one Instagram image and a reminder for the following week. The copy includes a venue, a booking link and a time zone. An editor must approve the final wording. This is a workload you can use to assess a connector, not a report of a completed test.
Start by naming the exact brand workspace and destinations. A personal LinkedIn profile and a company page should have separate entries in the brief. Ask the assistant to return those destinations before creating content. That makes a mistaken account choice visible while the work is still reversible.
Next, request drafts only. Specify the asset and the final caption for each destination. Require a response containing the saved post identifier, its state and any intended publication time. Open the resulting drafts in the scheduler. Check the actual image crop and link destination; a fluent response in chat cannot show whether the stored media matches your brief.
Then make one deliberate correction, such as changing the venue. Ask for the existing drafts to be edited rather than recreated. Compare identifiers afterward so you can spot accidental duplicates. The point is to establish that the assistant can maintain a coherent set of posts as requirements change.
Finally, stop at review. Record who is responsible for moving approved content into the live schedule. A connector fits this campaign only if that boundary is understandable to the people who will operate it every week.
Approval permission needs its own decision
Planable documents that its MCP connection inherits the user's permissions, including the ability to approve where that user can already do so. Draft-first creation therefore does not mean the connected assistant is incapable of signing off other content. Planable permissions.
Write down two separate responsibilities: who may prepare content and who may authorize publication. If your process requires independent review, connecting an assistant through the final approver's account deserves more scrutiny than connecting it through a drafting role. Ask whether the product and your chosen client can enforce the separation you need.
For any vendor, check what happens after an approved caption is edited. Does approval remain, reset or require a manual intervention? Do not infer the answer from the presence of an approval badge. Ask for the exact workflow behavior on the plan you intend to buy.
Check what the connection can reach
Buffer warns that an API key covers the account's organizations and channels, without per-organization scoping. Its write tools can publish immediately, and deletion can be permanent. Those details matter when one login manages several unrelated clients. Buffer connection security.
Before enabling any connector, inventory the content and accounts visible to the connected identity. Review the client that will store the credentials as carefully as the scheduler. Keep secrets out of shared briefs and screenshots. Give the people responsible for the account a documented way to revoke access, and decide who will maintain that connection when a teammate leaves.
A narrower task description is helpful, but it does not itself reduce the technical reach of a credential. Where the required account separation cannot be enforced, consider keeping the assistant on read-only work or using a different operating setup.
Analytics freshness changes the answer
Buffer's aggregate metrics refresh daily and can lag the network by up to a day; its response includes a freshness timestamp. Planable documents a metrics-refresh action, but that does not establish an end-to-end real-time guarantee. The reviewed Hootsuite MCP directory does not provide a universal freshness commitment for every metric. Buffer analytics, Planable analytics, Hootsuite directory.
For a Monday report, specify the reporting interval and time zone. Ask the assistant to identify the channels included and retain any unavailable values as unavailable. A missing metric should not quietly become zero. Compare like-for-like definitions before combining numbers across networks, particularly engagement rates with different denominators.
Which should you shortlist?
Choose Planable for closer evaluation when the valuable outcome is a reviewable set of drafts inside an established approval process. Choose Buffer when explicit post-management tools are central and you are comfortable with the credential's account-wide reach. Evaluate the relevant Hootsuite products when the workflow extends into customer operations or listening, with product access and plan gates confirmed separately.
Before committing, require three concrete answers from your finalist: which action completes the job, which identity permits it, and which saved state proves it happened. For the broader product trade-offs, see our Planable review, Buffer review and Hootsuite review.
