langchain-anakin

LangChain tools for Anakin: web scraping, site mapping and crawling, AI search, multi-stage agentic research, Wire (pre-built structured actions for hundreds of sites), website monitors, AI-engine answer comparison, saved browser sessions and AI-driven browser tasks. One tool for each of the 22 tools on Anakin's hosted MCP server (mcp.anakin.io), built on the official anakin-sdk Python client (not a separate HTTP implementation).

Install

pip install -U langchain-anakin
export ANAKIN_API_KEY="ask-..."   # free at https://anakin.io/signup

No key yet? AnakinScrapeTool, AnakinWireDiscoverTool, AnakinWireCatalogTool and AnakinWireReadActionTool work without one on a free per-IP allowance. The other tools return a ConfigurationError message with a signup link.

Tools

* Left out by AnakinToolkit(read_only=True).

Tool names follow the hosted server's, with an anakin_ prefix (anakin_scrape, anakin_wire_read_action, ...). Each argument's description reaches the model in the tool's schema.

AnakinWireRunTool (0.3.0's single Wire runner) still works but is deprecated: use AnakinWireReadActionTool and AnakinWireWriteActionTool.

Usage

from langchain_anakin import (
    AnakinScrapeTool,
    AnakinSearchTool,
    AnakinWireDiscoverTool,
    AnakinWireReadActionTool,
)

AnakinScrapeTool().invoke({"url": "https://example.com"})

AnakinScrapeTool().invoke({
    "url": "https://example.com/product",
    "output_schema": {"type": "object", "properties": {"price": {"type": "number"}}},
})

AnakinSearchTool().invoke({"prompt": "latest developments in AI agents"})

actions = AnakinWireDiscoverTool().invoke({"query": "search products on walmart"})
AnakinWireReadActionTool().invoke({"action_id": "walmart_search", "params": {"query": "phones"}})

Every tool also supports async (await tool.ainvoke(...)), backed by anakin.AsyncAnakin.

Use with an agent. AnakinToolkit gives the agent every tool, sharing one client:

from langchain.agents import create_agent
from langchain_anakin import AnakinToolkit

agent = create_agent(model, tools=AnakinToolkit().get_tools())

To give the agent fewer tools (and a shorter prompt), pass individual tools instead, as in the usage example above.

Read-only agents

AnakinToolkit(read_only=True) leaves out the 7 tools that change something on a website or in the user's Anakin account, or start a long paid job (marked * above). Use it for agents that should only look things up.

Payments

Like the hosted MCP server, AnakinWireWriteActionTool, AnakinWireBuildTool and AnakinBrowserTaskTool refuse anything that looks like it completes a payment or moves money (pay, checkout, purchase, place order, buy now, wire transfer, payout). Adding to a cart or filling in a form is allowed. Create those tools, or the toolkit, with allow_financial_actions=True to turn the check off.

Errors

Errors (bad key, no credits, a Wire site that needs a connected account) come back to the agent as text instead of raising, including any URL it needs to fix the problem.

Development

Requires anakin-sdk 0.2.x.
