agentsam-plugin-mcp is intentionally separate from inneranimalmedia-mcp-server.
- inneranimalmedia-mcp-server is the private InnerAnimalMedia operator/company control plane.
- agentsam-plugin-mcp is the public plugin capability plane.
- The two may share published AgentSam packages and protocols.
- They do not share implicit authority, credentials, unrestricted database access, arbitrary terminal access, or an automatically inherited tool catalog.
- Every public MCP tool is explicitly allowlisted.
Shared code is acceptable.
Shared authority is not.
Current public plugins
AgentSam Brand
AgentSam Brand answers:
Who are we, and how should that identity be expressed?

Current public tools:
brand.get_context
brand.inspect
brand.assets.list
brand.asset.inspect
brand.usage.find
brand.contract.draft
brand.consistency.evaluate
brand.plan

The public Worker consumes authorized evidence and the Worker-safe @inneranimalmedia/agentsam-brand/public package surface.
Filesystem/repository scanning remains a local or connected-resource capability; the public Worker does not gain arbitrary filesystem authority.
AgentSam Campaign
AgentSam Campaign answers:
What should we do now to achieve a measurable objective?

Current public tools:
campaign.get_context
campaign.brief.draft
campaign.concept.evaluate
campaign.concepts.rank
campaign.plan
campaign.brief.save
campaign.concept.save

Campaign can consume BrandContract, products, inventory, audience, margin, performance, SEO/search, and other authorized evidence.
Campaign does not own canonical Brand state, product manufacturing, catalog authority, content production, or arbitrary external-system mutation.
Product composition
Brand and Campaign are sibling products.

campaign strategy / evaluation / plan

Campaign may vary expression inside approved Brand territory, but it must not silently rewrite canonical Brand state.
If campaign work reveals a durable new brand expression, Campaign can propose a Brand extension.
Current execution boundary
The current public Campaign surface emphasizes:
read
understand
draft
evaluate
rank
plan
save

External publishing, deployment, launch execution, and unrestricted mutations are intentionally not exposed yet.
Future write actions must have narrow scopes, explicit authorization, approval where required, idempotency, receipts, and post-write verification where possible.
MCP transport
The public MCP endpoint uses the Web-standard Streamable HTTP transport from the Model Context Protocol SDK.
Routes:
GET     /health
GET     /.well-known/oauth-protected-resource
GET     /mcp
POST    /mcp
DELETE  /mcp

The current transport is stateless and registers only the explicit PUBLIC_TOOL_CATALOG.
Data
The Worker uses the canonical D1 binding:
DB

Current public runtime tables include:
public_users
public_identities
public_workspaces
public_connections
public_plugin_installations
public_brand_contracts
public_campaign_briefs
public_campaign_concepts
public_campaign_outcomes
public_tool_receipts

Commerce systems remain authoritative for live product, inventory, order, and pricing facts.
Analytics systems remain authoritative for observed performance facts.
Plugins consume or project those facts without pretending to own them.
Packages
Published domain packages:
@inneranimalmedia/agentsam-brand
@inneranimalmedia/agentsam-campaign

These packages remain portable independently of this MCP host.
Development
Requirements:
- Node.js 22+
- npm
- Wrangler
- Cloudflare account for D1/Worker operations
Install and verify:
npm install
npm run typecheck
npm test

Run locally:
npm run dev

Then connect an MCP client to:
http://localhost:8787/mcp

Database migrations
Local:
npx wrangler d1 migrations apply DB --local

Remote:
npx wrangler d1 migrations apply DB --remote

Inspect tables:
npx wrangler d1 execute DB --remote --command \
  "SELECT name FROM sqlite_master WHERE type='table' ORDER BY name;"

Architecture and product documentation
Durable architecture decisions live in:
docs/adr/

Product requirements live in:
docs/prd/

Current records:
docs/adr/ADR-0001-public-mcp-boundary.md
docs/adr/ADR-0002-brand-campaign-plugin-boundaries.md
docs/prd/PRD-agentsam-campaign.md

See the README inside each directory for the documentation convention.
Documentation rule
Use an ADR when deciding:
- product/domain ownership;
- authority or trust boundaries;
- portability requirements;
- storage/data authority;
- protocol/runtime boundaries;
- decisions that future implementations should not casually reverse.
Use a PRD when defining:
- the user problem;
- product promise;
- required workflows;
- capabilities;
- lifecycle;
- acceptance criteria;
- definition of v1;
- future product behavior.
In short:
ADR = why the system is shaped this way
PRD = what the product must accomplish

Security principles
- explicit public tool allowlist;
- least privilege;
- narrow scopes;
- no arbitrary terminal exposure;
- no raw D1 query tool;
- no inherited GitHub write authority;
- no automatic bridge to the internal operator MCP;
- missing evidence reduces confidence instead of creating fabricated facts;
- external writes require explicit authorization.
Status
The public MCP transport, Brand surface, Campaign surface, local/remote D1 schema, published Brand/Campaign domain packages, and current test suite are operational.
The broader plugin lifecycle, OAuth completion, additional skills, optional MCP UI, execution/measurement actions, and public-directory packaging continue to evolve.
