MCP Servers & Extensibility
MCP Servers & Extensibility
EdgeMob introduces Model Context Protocol (MCP) servers as a foundational layer in its decentralized platform. These servers empower mobile devices to host, execute, and share tools and AI functions—bringing extensibility, developer participation, and real-world usability directly to the edge. MCP servers transform every EdgeMob-powered device into an intelligent, programmable node in the global AI network.
What is a Mobile MCP Server?
A mobile MCP server is a sandboxed runtime embedded in the EdgeMob app. It enables structured tool execution through standardized APIs, designed for both local and remote consumption.
Localhost mode: private, offline execution of tools for agents and apps on the same device.
API Gateway mode: secure exposure of MCP endpoints to remote dApps, teams, or other devices with authentication, quotas, and auditable usage.
This flexibility allows developers to prototype locally, scale across teams, and monetize globally through EdgeMob’s decentralized gateway.
Architecture
Each MCP server instance includes:
MCP Manager UI – intuitive mobile interface for installing, configuring, activating, and swapping servers.
Rust MCP Host – orchestrates HTTP/WS endpoints, enforces budgets, collects metrics.
WASM Runtime (WASI) – sandbox for executing signed tool bundles with CPU/memory quotas.
Device-native Services – vector DB, key-value cache, secure file sandbox, biometric-enabled Web3 wallet, background task scheduler.
Lifecycle Flow
A developer publishes an MCP server bundle into the EdgeMob marketplace.
Users browse the marketplace, verify the signed package, and install it.
During configuration, users set memory/network limits, select exposure modes, and approve requested scopes.
The server is activated—tools become callable instantly via localhost or gateway.
Users can stop, restart, or hot-swap servers seamlessly without rebooting the app.
Publishing MCP Servers as a Developer
One of the most transformative aspects of EdgeMob is that any developer can publish their own MCP server and instantly reach a global audience.
Developer Workflow
Build: Create tools using EdgeMob’s Rust or TypeScript SDKs. Define capabilities in JSON schemas and package them into an
.mcpbundle.Test: Run the MCP server locally in the EdgeMob emulator or directly on-device. Validate scopes, budgets, and performance.
Sign: Secure the bundle with a developer key to ensure authenticity.
Publish: Upload the signed bundle to the EdgeMob Appstore, tagging it with metadata (category, use cases, required scopes).
Monetize: Define pricing in EGMO tokens—per-call usage fees, subscription models, or freemium tiers.
Maintain: Push updates, monitor feedback, and track usage metrics via the EdgeMob Developer Console.
Example Developer Use Cases
A data scientist publishing a Custom Analytics MCP Pack for local offline analytics.
A fintech developer publishing a DeFi Tools MCP Pack with DEX queries, risk scores, and wallet signing.
A productivity developer publishing a Task Automation MCP Pack to help teams orchestrate reminders and workflows.
By leveraging EdgeMob’s distribution and incentive model, developers are no longer bound by centralized app stores. Instead, they plug directly into a decentralized, token-incentivized ecosystem.
Tool Bundles & Extensibility
MCP servers extend their functionality with modular tool bundles packaged as .mcpbundle. Each bundle contains:
Manifest – schema, required scopes, performance budgets.
Binaries – WASM modules compiled with EdgeMob SDK.
Assets – embeddings, templates, metadata.
First-party Packs (MVP)
RAG Pack – document chunking, embeddings, search.
Data Pack – file operations, encryption, compression.
Web3 Pack – blockchain RPC, DEX queries, biometric signing.
Automation Pack – scheduling, notifications, background execution.
Compliance Pack – redaction, policy enforcement, audit logging.
Third-party Packs
Any developer can build and publish:
Domain-specific tools (medical, legal, financial).
Industry-tailored compliance packs.
Lightweight AI inference modules.
Security & Privacy
Scoped Permissions – least-privilege, JIT user prompts for sensitive actions.
Bundle Signing – integrity and authenticity guaranteed.
Sandboxing – strict CPU, memory, filesystem, and networking limits per bundle.
Biometric Controls – wallet signing and compliance-critical functions gated by biometrics.
Audit Logging – hashed arguments, scope usage, local exportable logs.
Performance Targets (MVP)
Cold start: under 800 ms.
Warm execution: under 150 ms p95.
Memory: 256–512 MB per MCP server (adjustable per device class).
Vector DB: up to 250k chunks, <100 ms search latency.
Business Value & EGMO Token Model
MCP servers create a developer-driven ecosystem inside EdgeMob:
EGMO for Usage – per-call microtransactions in EGMO.
EGMO for Rewards – mobile operators earn for compute, uptime, and service reliability.
EGMO for Developers – revenue shares for published MCP servers.
EGMO for Governance – staking determines reliability, slashing penalizes abuse.
This shifts the economics of AI away from centralized GPU-heavy infrastructure toward billions of underutilized mobile devices.
Key Use Cases
DeFi Copilot – local wallet analysis, DEX integrations, on-device signing.
Research Assistant – private document ingestion, embeddings, vector search.
Compliance Tools – local PII redaction and audits for enterprises.
Field Ops – offline GPS/camera/IMU capture with encrypted sync.
Creators – asset generation, metadata packaging, blockchain minting.
Productivity – journaling, summarization, scheduled recaps.
Multi-agent Apps – collaborative agents across small groups of devices.
Roadmap Beyond MVP
Curated Marketplace – decentralized Appstore governed by EGMO holders.
Cross-device Pairing – link mobile MCP servers with desktop/server counterparts.
Trusted Execution – TEE + zero-knowledge attestations for high-assurance workflows.
Multi-tenant Concurrency – safe execution of multiple MCP servers per device.
MCP Swarms – distributed coordination across groups of devices for large-scale tasks.
