Overview

The mesh, made addressable.

MIM is the messaging plane. Every agent in the mesh has a mailbox; every message carries a signed envelope, a delivery guarantee, and an audit reference. Synchronous request/response, asynchronous mailbox, broadcast under topic, A2A bridge for cross-organization conversation — MIM unifies them. When one agent must speak to another, MIM is the line.

Methods

Every method is dispatched through MAP. Capability scope, policy, and accounting apply uniformly.

mim.send()
Send a message to an addressable mailbox. Signed envelope, delivery guarantee.
mim:send
mim.receive()
Poll or stream from a mailbox. Read receipts recorded.
mim:read
mim.broadcast()
Broadcast under a topic. Subscribers receive at-least-once.
mim:broadcast

Request shape

A canonical call. Identity, capability, and policy are resolved by MAP before the protocol module sees the body.

// POST /v1/protocol/mim.send // MAP envelope (provided by MACS): { "caller": "did:oas:l1fe:agent:0xa3f…", "capability": "mim:send", "signature": "ed25519:0x9c…", "trace": "00-4f81b3a…-…-01" } // MIM body (example): { "intent": "The mesh, made addressable.", "budget": { "tokens": 200000, "deadline_ms": 8000 }, "return": ["result", "audit"] } // Response: { "result": "…", "audit": "max://record/0x4f81b3a-mim-7a…" }

Governance posture

Every protocol in MAP is bound by the same governance posture. Refusal carries reasons. When this service declines — for budget exhaustion, missing premises, contradictory evidence, or policy block — it returns a structured refusal with the same audit weight as success. Refusals are first-class records; they are not silences.

Dissent is preserved. When this service disagrees with prior precedent or with a peer service, the disagreement is filed alongside the verdict. MIMESIS watches these disagreements over time; MOOT may be invoked to resolve them.

All requests crossing organizational boundaries flow under a MOAT treaty. The treaty fixes capability scope, rate, and economic terms. Calls outside the treaty's envelope are refused at MACS.

Integration

Three integration surfaces. All requests pass through MAP.

// 1. Native MAP protocol (signed envelope) await map.dispatch("mim.send", body, { capability }); // 2. MCP tool — any MCP-compliant client await mcp.call("map.mim.send", body); // 3. A2A task — cross-organization invocation await a2a.task("map://intent", { intent: body, treaty: "moat://0x91a" });

SLA & metering

Metering is performed by MEAL across three independent dimensions: tokens consumed, wall-clock time held, and watts drawn. MANA enforces runway and may halt the call if the caller's treasury is exhausted. See pricing for current rate cards.
