SOCIAL PUBLISHING INFRASTRUCTURE FOR AGENTS

Let agents publish.
Keep proof of what happened.

Give your agent access to publish approved copy on X and Threads, with explicit schedules and receipts showing what happened. You control the accounts and permissions. LinkedIn Page access requires provider approval.

Where do you want to start?

Publish from your workspaceUse the hosted service. Connect accounts, approve copy and schedule posts. No installation needed. Connect an agentYou control its accounts, permissions and approval. Use remote MCP or HTTP. Run on your own machineInstall on Linux, pair the machine and review the switch to local execution. Account credentials stay in the cloud.

Run PostSteward on your machine.

Install the full runtime, pair it with your owner workspace and choose one publishing executor.

Need original release copy? Connect your own model account to prepare strategy and channel drafts from release evidence, then review and approve exact copy before delivery. Your selected customer account pays for generation; PostSteward subscription charges are separate.

Install PostSteward

INTENT Exact approved copy

Dispatch never silently rewrites the campaign.

AUTHORITY Scoped, revocable agent access

Publishing, scheduling, automation and billing stay separate.

EVIDENCE Receipts, not assumptions

Verified, unverified and ambiguous effects remain distinct.

ONE PUBLISHING PATH

A post moves through one deliberate sequence.

Connect an account, review your text, choose when to publish and check the result. You stay in control of what your agent may do.

01 · CAPTURE INTENT

Make the consequential details explicit before dispatch.

Campaign text, destination and project routing become a durable claim boundary before any social provider is touched.

  • Exact copy remains exact at dispatch.
  • Destination identity is resolved before the write.
  • An idempotency key belongs to the operation, not the transport attempt.

Destination @proofandstate · Threads
Approved text Agents can publish autonomously without making the outcome unknowable. PostSteward keeps the intent and receipt together.
Claim boundary text hash · account id · operation idempotency key
02 · ROUTE THE EFFECT

Separate provider execution from transport noise.

A timeout is not permission to publish twice. PostSteward preserves the state of the external effect and makes an uncertain outcome inspectable.

  • Durable schedules survive the agent disconnecting.
  • Provider writes are fenced against blind duplicate retries.
  • Cancellation and replacement remain explicit operations.

03 · INSPECT EVIDENCE

Success is one state. Uncertainty gets its own state too.

The receipt model is designed for operators and agents to reason from the same evidence instead of compressing every outcome into green or red.

  • Verified means the recorded post was independently read back.
  • Ambiguous means the write may have happened and should not be repeated blindly.
  • Blocked and failed states remain distinct from provider uncertainty.

CONNECT AN AGENT

Connect your agent to approved publishing.

Let your agent submit reviewed copy, schedule it and inspect the result. Start with an owner-issued token limited to the operations it needs. Choose remote MCP or HTTP; supported browsers can also use WebMCP.

OpenAPI help.json llms.txt operations

Keep approval and account connections in your workspace. Read the agent setup guide for CLI via HTTP, document.modelContext and the operation catalogue. Provider API fees, if any, are separate. 

POST https://app.poststeward.com/api/operations/schedule_create
Authorization: Bearer <scoped-agent-token>

FREE AND ADVANCED

Pay for continuing operation, not permission to publish.

Choose model and funding deliberately

Owner settings support Cloudflare Workers AI and OpenAI through prepaid Cloudflare AI Gateway Unified Billing, plus existing direct OpenAI. Choose a reviewed model, job/day budgets and optional fallback. Saving validates metadata without generating content or changing billing. Credits and provider charges belong to your account; PostSteward supplies no hidden company-funded fallback.

Live customer billing and human quality acceptance are pending. Check private model status and attempt evidence before relying on a route. Approval still creates exact reviewed copy for a separate delivery action.
