πŸš€ SIGIL Launch Strategy

Maximum Awareness, Minimum Time

This document outlines the go-to-market plan for SIGIL (sigil-protocol) β€” an open Rust protocol for securing AI agent-to-tool interactions.

Week 1: Hacker News + Reddit (Days 1-3)

1. Hacker News β€” "Show HN" Post

Highest Priority

Title

Show HN: SIGIL – The missing security layer for MCP agent-to-tool interactions

Post Body

MCP (Model Context Protocol) lets AI agents call tools, but has zero security:
no identity verification, no content scanning, no audit trail, no permission
gating.

SIGIL is an open Rust protocol that fills this gap. 5 traits you implement
with your own backends:

  - IdentityProvider β€” bind users to trust levels (eIDAS, OIDC, SSI)
  - SensitivityScanner β€” detect secrets before they reach the LLM
  - VaultProvider β€” encrypt intercepted content
  - AuditLogger β€” tamper-evident event logging
  - SecurityPolicy β€” risk gating + rate limiting

Plus a reference MCP server that wraps any tool set with all five layers.

2. Reddit β€” Two Subreddits

r/rust (~300K members)

Title: "sigil-protocol: securing MCP agent-to-tool interactions with identity, scanning, and audit traits"

Emphasize: trait design, test coverage (29 tests), EUPL choice, spec docs.

r/LocalLLaMA (~500K members)

Title: "Open protocol for securing AI agent tool calls β€” identity gating, secret scanning, audit trails"

Emphasize: Ollama/vLLM compatibility, local-first, no cloud dependency.

Week 1-2: Social & Community (Days 3-7)

3. X/Twitter Thread

🧡 We just published SIGIL β€” the missing security layer for AI agents.

MCP lets agents call tools. But MCP has:
❌ No identity verification
❌ No content scanning  
❌ No audit trail
❌ No permission gating

SIGIL fixes all four. Here's how ↓

1/ Identity β€” IdentityProvider trait binds users to trust levels.
   eIDAS, OIDC, SSI β€” you pick the backend.

2/ Scanning β€” SensitivityScanner catches secrets BEFORE they reach the LLM.
   API keys, IBANs, PII β€” domain-specific patterns.

3/ Audit β€” AuditLogger creates tamper-evident logs of every action.

4/ SigilMcpServer wraps ANY tool set. 4 lines of Rust.

4. Rust Community

Rust Discourse

Post on users.rust-lang.org in the "announcements" category.

This Week in Rust

Email twir@rust-lang.org β€” reaches ~30K Rust developers weekly.

5. LinkedIn Post

Target EU tech/policy audience. Emphasize: EUPL-1.2, eIDAS identity, AI Act compliance, "Built in Europe" narrative.

Week 2-3: Strategic Outreach (Days 7-14)

6. GitHub Issues on Strategic Projects

Open friendly, helpful issues that create permanent backlinks:

Project Issue Title Angle
modelcontextprotocol/specification "RFC: Security extension for tool call identity + audit" Propose _sigil as standard extension
anthropics/anthropic-cookbook "Example: Adding security to MCP tool calls" Offer to contribute a cookbook recipe
ollama/ollama "Feature: Audit trail for tool-use interactions" Reference Sigil as ready solution

7. Blog Post

Title: "MCP Has No Security Layer. We Built One."

Publish on: Dev.to (instant distribution), Medium (SEO), personal blog (linked from sigil-protocol.org).

Structure: The problem (2 paragraphs) β†’ What we built (diagram) β†’ Code example (4 lines) β†’ Why EUPL (1 paragraph) β†’ Call to action.

Week 3+: Amplification

8. NLnet / NGI Funding Application

Apply to NLnet.nl under NGI Zero. They fund EU open source security projects. Gives you: funding (€5-50K), credibility ("NGI-funded"), EU network.
