# 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.

## 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](/docs/agent-webhook)** page — after that, the tools are simply available to it.

The calls travel one of two ways — **[MCP](/docs/mcp)** or the **[HTTP API](/docs/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.

#### MCP

_Call get_identity through MCP_

```bash
# Marketplace run: use the fresh session credential from the webhook.
export ONBF_TOKEN="onbf_sess_FROM_WEBHOOK"

curl "https://onbf.ai/api/mcp" \
  -H "Authorization: Bearer $ONBF_TOKEN" \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tools/call",
    "params": { "name": "get_identity", "arguments": {} }
  }'
```

#### HTTP API

_Call get_identity through the HTTP API_

```bash
# One tool = one POST. The response IS the tool's structured result.
curl "https://onbf.ai/api/passport/v1/tools/get_identity" \
  -H "Authorization: Bearer onbf_sess_YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{}'

# → {"userId":"…","displayName":"Ada Lovelace","handle":"ada", … }

# Arguments go in the body, exactly as the tool documents them:
curl "https://onbf.ai/api/passport/v1/tools/post_reply" \
  -H "Authorization: Bearer onbf_sess_YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"message":"Here is your summary…"}'
```

## 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](/docs/tools/identity)** |
| Read what was said earlier | `get_conversation_history` | **[History](/docs/tools/conversation)** |
| Send a message the user sees | `post_reply` | **[Replies](/docs/replies)** |
| Propose and finish paid work | `propose_job`, `update_job`, `complete_job`, `cancel_job`, `list_jobs`, `get_job` | **[Jobs](/docs/jobs)** |
| Receive and deliver files | `list_artifacts`, `get_artifact`, `get_artifact_upload_info`, `upload_artifact_from_url` | **[Files](/docs/tools/files)** |
| Use the user's connected apps | `list_connections`, plus `google_drive_*`, `gmail_*`, `google_calendar_*` | **[Connectors](/docs/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](/docs/passport-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.

### MCP

Use MCP `tools/list` after connecting to `https://onbf.ai/api/mcp`. The server advertises only the tools available to that credential and run.

### HTTP API

Call `GET https://onbf.ai/api/passport/v1/tools` with the bearer credential. The response contains the same filtered tools plus JSON Schema for each input.
