Bartholomew AI • BTP v2.4 Standards Track

Resilient MCP Security Proxy, Sub-5µs Transactional Rollbacks & In-Flight Secret Scrubber

[EXECUTIVE_SUMMARY] What is Bartholomew & BTP v2.4?

Bartholomew is the resilient, transactional execution runtime and MCP security proxy for autonomous AI agents.
Built on the Bartholomew Trust Protocol (BTP v2.4 Standards Track), it moves beyond brittle "prompt firewalls" by providing sub-5 microsecond Copy-on-Write workspace micro-rollbacks, bi-directional in-flight credential scrubbing, and chained RFC 8785 Ed25519 audit manifests. It integrates transparently with Claude Desktop, Cursor, Windsurf, Devin, and any standard MCP client with zero code changes.

⚡ 3-Second Live Terminal Showcase (v2.4)

Test in-flight credential scrubbing, boundary violation micro-rollback (<5µs), and chained Ed25519 audit manifests on your machine:

# Clone and run the live v2.4 simulation
git clone https://github.com/ivegotahunnitonit/bartholomew.git
cd bartholomew
python cli.py demo-v24

60-Second Multi-Language Quickstarts

1. Python (pip install btp-guard)

from btp_guard import Guard

# Set spend limit and max retries
guard = Guard(spend_cap=100.0, max_retries=5)

# Protect any agent tool or function with a decorator
@guard.protect
def execute_database_query(sql_query: str):
    # If the agent attempts a DROP TABLE or exceeds budget,
    # it is blocked in <5 microseconds before executing.
    return db.execute(sql_query)

# Or check actions directly:
result = guard.check("rm -rf /var/data")
print(result["allowed"]) # False
print(result["reason"])  # "Policy Violation: Trajectory contained forbidden pattern 'rm -rf'"

2. TypeScript / Node.js (npm install btp-guard)

import { BTPGuard } from 'btp-guard';

const guard = new BTPGuard();
const receipt = guard.evaluateAction({
  agentId: 'claude-desktop',
  actionType: 'DATABASE_MUTATION',
  payload: { query: 'DROP TABLE accounts;' }
});
console.log(receipt.verdict); // "DENY" (Blocked in 11 µs)

3. Go (go get github.com/ivegotahunnitonit/bartholomew/pkg/btp)

package main
import "fmt"
import "github.com/ivegotahunnitonit/bartholomew/pkg/btp"

func main() {
    guard := btp.NewGuard()
    verdict := guard.Evaluate("AGENT_01", "DB_READ", map[string]interface{}{"id": 101})
    fmt.Println("Verdict:", verdict) // ALLOW (0.00s latency)
}

4. Command-Line CLI

# Validate declarative YAML security policies
python -m src.cli policy validate --file policies/default_security_policy.yaml

# Test an action payload directly in your terminal
python -m src.cli policy eval -f policies/default_security_policy.yaml -p '{"query": "SELECT 1"}'
