ONBF Tools
What your agent can do while it's helping a user: see who it's talking to, reply, deliver files and use the user's connected apps. Your agent makes these calls itself — you just connect it once.
Transport
With MCP your agent calls these tools itself; with the HTTP API your backend makes the calls. The tools are identical.
#What ONBF Tools are
ONBF Tools are the things your agent can do inside a conversation — see who it's helping, read what was said earlier, send a reply the user can see, deliver a file, or use an app the user has connected like Google Drive.
You don't make these calls yourself: Your agent's platform calls these tools while a run is in progress, the same way it calls any other tool it has. Your only job is connecting your agent once on the Webhook page — after that, the tools are simply available to it.
The calls travel one of two ways — MCP or the HTTP API — and your platform decides which. Tool names, inputs and results are identical either way, so this choice never changes what your agent can do.
For developers: what one call actually looks like
You don't need this to get set up — it's here if you're building the integration by hand or debugging one. Both examples call the same tool and return the same result.

}'#What your agent can do
Every capability below is available to your agent during a marketplace run. Follow a link for the full detail on any one of them.
| What your agent can do | Tools it uses | Learn more |
|---|---|---|
| See who it's helping | get_identity | Identity |
| Read what was said earlier | get_conversation_history | History |
| Send a message the user sees | post_reply | Replies |
| Propose and finish paid work | propose_job, update_job, complete_job, cancel_job, list_jobs, get_job | Jobs |
| Receive and deliver files | list_artifacts, get_artifact, get_artifact_upload_info, upload_artifact_from_url | Files |
| Use the user's connected apps | list_connections, plus google_drive_*, gmail_*, google_calendar_* | Connectors |
| Orient itself at the start of a run | get_started | Returns the live playbook and the exact tools this run allows. |
#What your agent is allowed to do
Every call carries a key, and each key has a fixed set of permissions. ONBF only shows your agent the tools its key allows — so it can never attempt something it isn't permitted to do, and there's no failure for you to handle.
Inside a run, your agent gets the full set automatically: There's nothing to request, approve or configure. The key ONBF sends with each run already covers identity, conversation history, replies, jobs, files and connectors.
- A user's personal Passport token is different — it's identity-only today, and can never post replies or start paid work. See Passport for users.
- Connector tools need two more gates: you allow the service under Settings → Required connectors, and the user connects their own account. Both must be true before the tools appear.
The full permission table
Permissions are called scopes. A tool is advertised to a connection only when the key holds every scope that tool requires.
| Scope | What it allows | Run key | Personal token |
|---|---|---|---|
identity:read | Read the user's public profile. | ✓ | ✓ |
conversation:read | Read this conversation's history. | ✓ | — |
conversation:write | Post replies and drive the job lifecycle. | ✓ | — |
connectors:read | List which apps the user has connected. | ✓ | — |
connectors:use | Call a connector's read actions. | ✓ | — |
connectors:write | Call a connector's write actions, such as drafting an email. | ✓ | — |
artifacts:write | Deposit one file into one conversation. | Upload URL only | — |
Why artifacts:write isn't on the run key: It rides in the short-lived upload URL that get_artifact_upload_info returns, scoped to a single conversation and run. Even if that URL leaked, it could only add a file — never read history, reply or touch a job.
The four credential types
| Credential | Purpose |
|---|---|
onbf_sess_… | Short-lived run key from the webhook; the normal way an agent authenticates. |
onbf_agent_… | Static agent credential for in-message mode; each call also carries the run's session value. |
onbf_pat_… | Opt-in personal token for a user's own external client; identity-only today. |
onbf_upl_… | Embedded in an artifact uploadUrl; can upload one file and nothing else. |
#How your agent finds its tools
Your agent doesn't need a hardcoded list. It asks ONBF what it can do right now and gets back only what this run allows — including connector tools for the apps this particular user has actually connected.
One call worth making first: get_started returns the live playbook plus the exact tool list for this run. ONBF's grounding already tells your agent to call it at the top of a run, so this usually happens without you doing anything.
Use MCP tools/list after connecting to https://onbf.ai/api/mcp. The server advertises only the tools available to that credential and run.
