Fisemarco / DEVELOPERS

Identity in your runtime.
Authority at the boundary.

Use the Node runtime SDK for enrollment and gated task execution. Python, Go and Java offer signed transport clients and full lifecycle adapters using the same local Node engine. Keys remain in your runtime; do not upload private keys to the website.

New to AI agent identity?

Understand passports, operator-authorised enrollment and the evidence behind identity checks before choosing an integration.

Connect your coding assistant.

Use the Fisemarco plugin with Codex or ChatGPT, the Claude Code package, or a compatible MCP client. Setup connects your assistant to the official hosted service; your runtime keeps its private keys.

Open source on GitHub.

Explore the application, backend, SDKs, plugins, protocols, migrations and tests. Original Fisemarco code is available under Apache 2.0, with retained third-party notices.

The public repository contains a clean source history. Production credentials and private agent records are excluded. Self-hosting requires your own registry key, backend, identity gateway and operational configuration.

Intelligence Control Plane

Route each step through rules, context, tools, evaluated capabilities or approved models. The Node executor uses your registered identity and bounded authority; provider keys stay in your runtime.

Builder plugins

Connect Codex or ChatGPT through the Fisemarco personal plugin. A Claude Code package supplies the remote MCP configuration and startup integration skill. Other compatible clients can use the same MCP endpoint.

Plugin v3 includes 21 tools for identity, governance, intelligence policies, capability reviews, metrics and execution traces.

One lifecycle, four languages

Enrollment, durable identity, task gating, cancellation, outcome recovery, key rotation and Cybersphere. Python, Go and Java lifecycle adapters require Node 22+ locally.

Trust graph

Explore typed relationships, live authority chains and signed evidence in your organisation workspace. Paginate and export the graph through the API or MCP connection.

Fisemarco technical certification

Assess an agent against published technical identity criteria, issue a signed credential and check or revoke it throughout its validity.

Integrate safely

Create an enrollment policy in the builder workspace, then enroll a runtime and retain its private key securely.
Assign the passport to an organisation workforce and issue bounded authority.
Use the signed authority check before work. Submit an exact-input approval request when the result is ESCALATE.
An authorised person reviews the request in the governance centre. Use runAuthorizedTask to acquire a permit and consume its bound approval at task start. Enforce the same action and input at the resource.
Record outcomes and review observed activity. A signature proves the reporting key; it does not independently prove task success.

Downloadable clients implement Fisemarco’s current profile. They are not an A2A, MCP, SPIFFE or ISO certification. All four languages can use the shared lifecycle engine; Python, Go and Java also provide narrower standalone transport clients.
