Meet ProtoMap · for teams running gRPC + Protobuf at scale

One service graph for every engineer and every AI agent.

A deterministic engine that maps every service, API and field across your monorepos and microservices. Refreshed on every commit, across every repo in your organization, and served to your engineers and their coding agents.

Built for the age of agentic coding

gRPC sprawl is coming. Stop burning tokens to rediscover it.

Every line an agent writes adds services, calls and fields that the next agent has to rediscover. ProtoMap keeps one deterministic map of all of it, so your context stays accurate and affordable however fast the code grows.

Monorepo-ready

Built for multi-million-line monorepos and sprawling microservices: one service graph across every repo, refreshed on every commit.

Enterprise-ready

Cloud hosted or deployed on-premises, with GitHub, Bitbucket and GitLab integrations and scans in CI on every pull request.

Future-proof against token costs

Agents query the graph instead of re-reading code, so the cost of an answer depends on the question, not on the size of your codebase.

Ask ProtoMap

The questions behind every cross-service change, answered from code.

Engineers ask in plain English in the web platform. Coding agents ask over MCP. Both get the same deterministic answer.

For “human” engineers first. Then for every AI coding agent.

Step 1 · Free

Install it on your machine

Install the ProtoMap web platform and CLI and query your organization’s service graph in plain English. Free for whatever code is scanned on your machine.

  • Self-hosted platform and CLI scanner
  • Bring your own AI provider: Anthropic, OpenAI, Google and others
  • MCP for your coding agent, with your local changes laid over the graph
$ curl -fsSL https://protomap.ai/install.sh | sh Install ProtoMap Free
Step 2 · Enterprise

Keep the graph fresh org-wide

The enterprise version keeps the service graph fresh across your entire organization, so agents stop cloning repositories they don’t own.

  • Cloud hosted or deployed on-premises in your org
  • Direct integrations with GitHub, Bitbucket, and GitLab
  • Runs scans in CI on every pull request
  • HoundDog.ai’s MCP Server gives every agent the full service map

Static analysis discovers. AI reasons. MCP delivers.

Why not just use an LLM?

HoundDog.ai is built to make your AI more effective, not to replace it.

01

Spend tokens on reasoning, not discovery.

The scanner discovers every service, API and field dependency, so your AI tokens go to higher-value work like assessing the blast radius, planning changes, and answering questions about your service graph.

02

Evidence you can stand behind.

The same commit always produces the same service graph. Every engineer and every agent gets the same answer about what a change will break, instead of output that varies with the prompt.

03

Easy to roll out org-wide.

The Rust scanner runs in CI on standard CPU infrastructure, across every repo and every commit, with negligible impact on build times.

The same engine, pointed at sensitive data
Privacy Code Scanner

Code-based evidence for GDPR data maps, RoPA & privacy reviews.

The static analysis behind ProtoMap also traces sensitive data into logs, storage, third-party and AI integrations. Ask the assistant about your data in plain English and explore the answer on an org-wide data map.

Code-based dataflow context

Fast, deterministic analysis with centralized context.

Engineering: cross-repo API and service context for your AI agents
The gap

API specs alone don't cover the services and fields consuming your APIs.

→
The cost

Without centralized dataflow context, agents burn tokens grepping repos and writing ad-hoc bash scripts to parse code relationships, often on code not even checked out locally, leaving AI with an incomplete picture.

→
With HoundDog.ai

An MCP server continuously fetches the exact cross-repo context, so prompting your agent to update a service or API runs 6.4× faster and 5.3× cheaper, with the full picture.
