What is an MCP resource?

An MCP resource is contextual data an AI client can read, such as documents, records, or workspace context.

MCP Resources | MCP Guide

Overview

MCP resources expose readable context to AI clients.

For publishing, resources can include brand guidelines, draft calendars, campaign briefs, post templates, and analytics summaries.

Why This Matters

MCP matters because it turns AI from a writing surface into an execution surface. Instead of stopping at generation, AI tools can trigger real product actions through a structured layer that respects permissions, workflows, and business logic.

Preflight Checklist

Define the workflow you want the AI tool to trigger.
Map each action to an existing Postly capability.
Keep permissions and workspace routing inside Postly.
Default to draft-first behavior when actions could be risky.
Log and validate every AI-initiated action.

Step-by-Step Playbook

Define resource types.
Scope resources by workspace.
Expose read-only context.
Use tools for actions.
Update resources when data changes.

MCP lets AI tools call real product actions instead of stopping at content generation.

Implementation Tips

Keep sensitive resources permissioned.
Prefer summaries over raw private data.
Separate read resources from write tools.

Example MCP Action Pattern

Reusable flow for “MCP Resources”

Intent: user asks the AI to perform a real workflow.
Tool call: AI selects a defined MCP action.
Validation: auth, workspace, and role checks run first.
Execution: Postly backend performs the requested action.
Result: structured output returns to the AI client.

Design Checklist

Map tools directly to product primitives.
Use one shared backend action layer across channels.
Support both MCP and API packaging where needed.
Keep AI-triggered actions reversible where possible.
Bias toward draft-first execution for content workflows.

Postly Workflow

In Postly, MCP should expose the product’s existing capabilities rather than invent a new execution system. That means drafts, scheduling, approvals, calendars, accounts, and analytics can be made available across AI-native and integration surfaces while Postly stays the source of truth for execution.

Postly remains the control layer while AI becomes the trigger or creation surface.

Metrics to Watch

Tool usage: which MCP actions get used most often.
Workflow completion: how often AI-generated intent becomes a completed action.
Approval rate: how many AI-triggered drafts move through review successfully.
Time saved: whether AI-triggered flows reduce execution time.
Error rate: how often auth, validation, or workflow failures occur.

Troubleshooting Common Issues

Too much logic in MCP: move business logic back into Postly services.
Unsafe actions: default to drafts and approvals instead of direct publishing.
Permission mismatches: enforce workspace and role checks before execution.
Generic tool design: define clearer, narrower action schemas.

Next Steps

Start by exposing one high-value Postly workflow through MCP, then validate how often users complete that flow from an AI surface. From there, expand into adjacent actions like approvals, scheduling, queue checks, and analytics.
