engini

Agent-first Python SDK for the Engini Public API — discover tools, execute them against your connected apps, and wrap them as LLM tool definitions.

pip install engini            # SDK
pip install 'engini[cli]'     # SDK + the `engini` CLI

Quickstart

from engini import Engini

client = Engini(api_key="eng_…")          # or set ENGINI_API_KEY

# Discover canonical tool schemas
tools = client.tools.get(applications=["salesforce"], search="accounts", limit=5)

# Execute a tool against a connection
conn_id = next(c.connection_id for c in client.connections.list(application="salesforce"))
result = client.tools.execute(
    "salesforce_getrecords", {"sobject": "Account"}, connection_id=conn_id
)
print(result.output)

JWT auth is the fallback: Engini(token="<jwt>", company_token="<id>"), or set ENGINI_API_TOKEN / ENGINI_COMPANY_TOKEN. With an API key the company is bound to the key, so no company token is needed. Point at another host with Engini(..., base_url=…).

Use with an LLM

Provider adapters wrap canonical schemas into vendor tool definitions client-side, with no vendor SDK dependency. OpenAI is the default; Anthropic is also available.

# Bind applications → connections once, then drive a tool-calling loop
toolset = client.toolset(tools=["salesforce_getrecords"], connections={"salesforce": "Prod"})

openai_tools = client.provider.wrap_tools(toolset.tools())   # plain OpenAI tool-JSON dicts
# … send openai_tools to the model, get a response …
results = toolset.handle_tool_calls(llm_response)            # runs the calls, returns results

client.toolset(...) builds a local toolset (no I/O until used) or loads a server one via toolset_id=….

Files

Tools whose input_schema marks a field "format": "engini/file" accept files. Wrap a file with engini.File and pass it as the field value — the SDK base64-encodes it into the {base64_content, mime_type, filename} wire shape. A field can take a single file or a list, per the tool's schema.

from engini import Engini, File

client = Engini(api_key="eng_…")
client.tools.execute(
    "doc_summarize",
    {
        "document": File.from_path("report.pdf"),                  # single file
        "attachments": [File.from_path("a.png"), File.from_path("b.png")],  # list of files
    },
    connection_id=conn_id,
)

File.from_path infers the filename and mime type; File.from_bytes(data, filename=…, mime_type=…) and File.from_base64(…) cover in-memory content.

In the LLM loop an agent can't produce base64, so file fields are presented to it as string fields. Register the files you'll allow and let the model reference one by key:

results = toolset.handle_tool_calls(
    llm_response, files={"report": File.from_path("report.pdf")}
)

What this adds over the raw REST client

Built on the autogenerated engini-client, the SDK adds what the generated client deliberately lacks: typed errors (the EnginiError family), retry/backoff, auto-pagination, pluggable auth (ApiKeyAuth / BearerAuth), Provider adapters for OpenAI/Anthropic, and the ergonomic Toolset object.

Command-line interface

The engini[cli] extra ships an engini command — a machine-first CLI over the same surface.

engini --help     # login · logout · whoami · tools · applications · connections · connect

engini login --api-key eng_…                 # or run interactively on a TTY
engini whoami                                 # who am I / which company
engini applications list --available          # discover connector apps
engini tools list --application salesforce    # discover tools
engini tools call salesforce_getrecords --args '{"sobject":"Account"}' --connection <id>
engini tools call doc_summarize --args '{}' --file document=@report.pdf   # attach a file
engini connect                                # open the connections page in your browser

Output is machine-first: human-readable on a TTY, compact JSON when piped, pretty JSON with --json. Every command also accepts --quiet and --schema (a machine-readable arg schema), and mutating commands accept --dry-run. Exit codes are a stable contract (0 ok · 2 usage · 3 auth · 4 not found · 5 validation · 124 timeout).

Credentials and host config live in $XDG_CONFIG_HOME/engini/config.toml (%APPDATA%\engini\config.toml on Windows), written 0600. Resolution order is flags > environment > config; the env vars are ENGINI_API_KEY (preferred) or ENGINI_API_TOKEN, plus ENGINI_COMPANY_TOKEN.
