[ SDKs ]

Build agents in the language you already ship.

Four first-party SDKs wrap the MeerTech API. Every SDK gives you the same primitives — agents, tools, policy envelopes, runs, traces — and the same semantics. Pick the runtime that matches your systems of record.

02Python

First-class for data + finance teams.

The Python SDK mirrors the platform model: declare the agent, register tools with decorators, emit plans as Python functions. Async-first.

agents/reconciler.py

python

from meertech import Agent, policy, tool, context

@tool(provider="mcp.zoho_books", action="post_journal", idempotent=True)
async def post_journal(entry: dict) -> str:
    """Post a journal entry into Zoho Books. Returns the journal id."""

agent = Agent(
    name="finance.reconciler",
    role="finance.agent",
    policy=policy.envelope(
        scope=["post.journal", "reconcile.bank"],
        limit_usd=50_000,
        approvers=["controller.queue"],
        escalate_above_usd=25_000,
    ),
    tools=[post_journal],
)

@agent.plan
async def close_period(period: str):
    invoices = await context.invoices(period=period, status="open")
    for inv in invoices:
        decision = await agent.sentinel.evaluate("post.journal", inv)
        if decision.allow:
            await post_journal(inv.to_entry())
        else:
            await agent.escalate(inv, reason=decision.reason)

if __name__ == "__main__":
    agent.run(close_period, period="2026-04")

03TypeScript

Typed plans, typed tools.

The TypeScript SDK gives you end-to-end types from tool schemas through to run results. Zod schemas double as runtime validators for tool inputs.

src/reconciler.ts

typescript

import { z } from "zod";
import { Agent, policy, tool } from "@meertech/sdk";

const JournalEntry = z.object({
  vendor: z.string(),
  amount_usd: z.number(),
  period: z.string().regex(/^\d{4}-\d{2}$/),
});

const postJournal = tool({
  name: "zoho_books.post_journal",
  provider: "mcp.zoho_books",
  input: JournalEntry,
  output: z.string(),
  idempotent: true,
});

export const agent = new Agent({
  name: "finance.reconciler",
  role: "finance.agent",
  policy: policy.envelope({
    scope: ["post.journal", "reconcile.bank"],
    limitUsd: 50_000,
    approvers: ["controller.queue"],
    escalateAboveUsd: 25_000,
  }),
  tools: [postJournal],
});

agent.plan("close_period", async ({ inputs, context, sentinel }) => {
  const invoices = await context.invoices({ period: inputs.period, status: "open" });
  for (const inv of invoices) {
    const decision = await sentinel.evaluate("post.journal", inv);
    if (decision.allow) {
      await postJournal({ vendor: inv.vendor, amount_usd: inv.total, period: inputs.period });
    } else {
      await context.escalate(inv, { reason: decision.reason });
    }
  }
});

04Go

For infra and edge.

The Go SDK is tuned for connector sidecars and edge runtimes where binary size and startup time matter.

cmd/reconciler/main.go

package main

import (
    "context"
    "log"

    "github.com/meertech/meertech-go/agent"
    "github.com/meertech/meertech-go/policy"
    "github.com/meertech/meertech-go/tool"
)

type JournalEntry struct {
    Vendor    string  `json:"vendor"`
    AmountUSD float64 `json:"amount_usd"`
    Period    string  `json:"period"`
}

func main() {
    post := tool.New[JournalEntry, string]("zoho_books.post_journal",
        tool.Provider("mcp.zoho_books"),
        tool.Idempotent(true),
    )

    a := agent.New("finance.reconciler",
        agent.Role("finance.agent"),
        agent.Policy(policy.Envelope{
            Scope:            []string{"post.journal", "reconcile.bank"},
            LimitUSD:         50000,
            Approvers:        []string{"controller.queue"},
            EscalateAboveUSD: 25000,
        }),
        agent.Tools(post),
    )

    a.Plan("close_period", func(ctx context.Context, r *agent.Run) error {
        invoices, err := r.Context.Invoices(ctx, "2026-04", "open")
        if err != nil { return err }
        for _, inv := range invoices {
            dec, _ := r.Sentinel.Evaluate(ctx, "post.journal", inv)
            if dec.Allow {
                _, _ = post.Call(ctx, JournalEntry{inv.Vendor, inv.Total, "2026-04"})
            } else {
                _ = r.Escalate(ctx, inv, dec.Reason)
            }
        }
        return nil
    })

    if err := a.Run(context.Background()); err != nil {
        log.Fatal(err)
    }
}

05Java

For JVM enterprise stacks.

The Java SDK targets JVM 17+ and integrates cleanly with Spring and established enterprise observability stacks.

            .provider("mcp.zoho_books")
            .idempotent(true)
            .build();

    public static void main(String[] args) {

            .tool(POST_JOURNAL)
            .plan("close_period", run -> {
                var invoices = run.context().invoices("2026-04", "open");
                for (var inv : invoices) {
                    var decision = run.sentinel().evaluate("post.journal", inv);
                    if (decision.allow()) {
                        POST_JOURNAL.call(inv.toEntry());
                    } else {
                        run.escalate(inv, decision.reason());
                    }
                }
            })
            .build();

        agent.run();
    }
