Tokenectomy Razor

公式

Fast, lightweight Rust-based MCP server designed to optimize prompt payloads and reduce token overhead for LLMs.

Tokenectomy Razor MCPで何ができますか?

  • Sanitize error logs — Ask to scrub framework noise and redact credentials from a stack trace with get_error_context, returning only relevant local source.
  • Search for known fixes — Have the assistant query Stack Exchange via search_stack_overflow using sanitized error signatures to find relevant solutions.
  • Apply validated code patches — Request atomic file edits with apply_code_patch, which runs syntax checks and rolls back automatically on failure.
  • Detect code defects — Use analyze_code for static AST analysis to find resource leaks, security issues, and bugs with precise LSP coordinates.
  • Run a local redaction proxy — Configure the --proxy mode to intercept and sanitize LLM API traffic on localhost before forwarding upstream.

What It Does

Tokenectomy Razor is an autonomous, machine-to-machine (M2M) Model Context Protocol (MCP) server and stream processing engine written in safe Rust. It intercepts error logs from AI agents, strips 90%+ of framework noise, automatically redacts secrets (JWTs, API keys, database credentials), and caches sanitized contexts with a 24-hour TTL—all without sending raw data to external services.

In 30 Seconds

The Problem:

  • AI agents waste tokens on framework noise (node_modules, site-packages, .cargo/registry)
  • Sensitive credentials accidentally leak into LLM logs (AWS keys, database URLs, API tokens)
  • Repeated identical errors cost money for every retry

The Solution:

Raw Error Log (38K tokens + secrets)
    ↓
[Redact secrets locally] → [Filter framework frames] → [Extract user code]
    ↓
Sanitized Context (2K tokens, no secrets) → Safe to send to LLM

Real Example

Before:

$ cat error.log | head -20
Error in /home/user/.cargo/registry/src-xxx/tokio-1.35/src/runtime/mod.rs:12345
  at /home/user/.cargo/registry/src-yyy/serde/src/lib.rs:456
  Database connection failed: postgresql://admin:secretpass@db.example.com:5432/mydb
  JWT Auth token: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIn0...
  [... 500+ more framework frames ...]

After:

$ cat error.log | razor --scrub
Error in /home/user/src/main.rs:42
  at /home/user/src/utils.rs:18
  Database connection failed: [CONNECTION_STRING_REDACTED]
  JWT Auth token: [JWT_REDACTED]

Benefits:

  • ✅ 95% smaller context (2K vs 38K tokens) → Save money on LLM API calls
  • ✅ Zero secrets in logs → Sleep better at night
  • ✅ Identical errors cached → Second retry costs $0

  • Deep Polyglot Trace Surgery: In-memory parsing across Rust, Python, TypeScript/JavaScript, Go, Java/Kotlin (Spring Boot 3, Tomcat, Hibernate, Netty, Undertow, HikariCP), C/C++ (AddressSanitizer, GDB, glibc), and PHP. Surgically filters noisy framework internals and runtime boilerplate while isolating genuine user application code frames.
  • Static AST Code Analysis Engine (analyze_code): High-throughput static AST analysis detecting unclosed handles, resource leaks, and security vulnerabilities with bounded execution limits (50K AST nodes, 10 MB file limit) and precise LSP UTF-16 coordinates.
  • Glama Grade A TDQS Compliance: 100% Tool Definition Quality Score with explicit schema boundaries, runtime preconditions, and full disclosure across all MCP tools.
  • AI Gateway Reverse Proxy (--proxy): Transparently intercepts prompt streams on 127.0.0.1:8080, performing real-time token excision and credential sanitization before upstream forwarding to OpenAI, Anthropic, or Ollama.
  • Zero-Knowledge Secret Redaction: Linear-time deterministic regex engine strips JWTs, API tokens, cloud access keys, connection strings, and private keys prior to network transmission. All processing happens locally.
  • SHA-256 Idempotency Cache: Stores deterministic responses with a 24-hour TTL. Repeated CI/CD or agent loop failures incur zero upstream API cost.
  • Path Traversal Containment: All MCP filesystem access is canonicalized and locked to the workspace root boundary (CWD). No ../ escapes or symlink breakouts.
  • M2M Protocol Compliance: Native JSON-RPC 2.0 stdio server compliant with the official Model Context Protocol specification.

Exposed MCP Tools

Tool NameCapability Description
get_error_contextPerforms trace surgery on error dumps, removes framework noise, redacts credentials, and extracts relevant local source context bounded to the workspace.
search_stack_overflowQueries Stack Exchange API for relevant error signatures using sanitized search terms.
apply_code_patchApplies atomic file modifications with post-write language syntax verification (cargo check, py_compile, node --check) and automated rollback on validation failure.
analyze_codePerforms static AST code analysis to detect resource leaks, security vulnerabilities, and code defects with bounded execution limits and precise LSP UTF-16 coordinates.

Quick Start

I use Claude Desktop

# 1. Add to claude_desktop_config.json (see MCP Integration section above)
# 2. When Claude encounters errors, it automatically uses "get_error_context" tool
# 3. Errors stay sanitized without any additional setup

I use GitHub Actions

# Add to your workflow (.github/workflows/build.yml)
- name: Sanitize Build Failure Log
  if: failure()
  uses: daffa2555/tokenectomy-action@v1
  with:
    log-file: 'build.log'
    output-file: 'sanitized.log'

# Now you can safely share sanitized.log without leak concerns

Parameters:

ParameterTypeDefaultDescription
log-fileString''Path to raw error log file to process
log-contentString''Direct string content if file is not specified
output-fileStringtokenectomy-sanitized.logPath for scrubbed output file
versionStringv1.2.1Binary release target version

I want max privacy (air-gapped environment)

# All redaction happens locally—no network calls except to your LLM
cargo install tokenectomy

# Process logs without any cloud services
echo $ERROR_LOG | razor --scrub --local-only

# Or from a file:
razor --scrub --file /var/log/app/error.log > sanitized.log

Advanced Usage

Standalone CLI

In addition to M2M agent mode, Razor provides CLI commands for terminal piping and local shell scripting:

# Scrub framework frames and output clean log
npm test 2>&1 | razor --scrub > sanitized.log

# Sanitize a specific log file
razor --scrub --file /var/log/app/error.log > sanitized.log

# CLI diagnosis with specific AI provider
razor --file error.log --provider openai
razor --file error.log --provider anthropic
razor --file error.log --local-only

AI Gateway Reverse Proxy Mode

Tokenectomy Razor can operate as a transparent local HTTP reverse proxy. It sits between client applications and upstream LLM providers (OpenAI, Anthropic, Ollama, OpenRouter), performing real-time token excision and credential sanitization before upstream forwarding.

Local Development (Default Loopback):

# Forward to OpenAI
razor --proxy --proxy-bind 127.0.0.1:8080 --upstream-url https://api.openai.com/v1

# Forward to local Ollama instance
razor --proxy --proxy-bind 127.0.0.1:8080 --upstream-url http://127.0.0.1:11434/v1

Point any standard SDK or IDE client to the local proxy:

export OPENAI_BASE_URL="http://127.0.0.1:8080/v1"
# Now all API calls are automatically sanitized

Production Proxy Hardening

Binding to external interfaces (0.0.0.0) requires explicit token authorization:

razor --proxy --proxy-bind 0.0.0.0:8080 --upstream-url https://api.openai.com/v1 --allow-remote --proxy-token "YOUR_SECURE_TOKEN"

Resource limits enforced: MAX_HEADER_SIZE (64 KB), MAX_BODY_SIZE (10 MB), client/upstream timeouts (30s / 60s), and a 128-connection concurrency cap.

Configuration

Configuration values can be set via ~/.tokenectomy.toml:

default_provider = "openai"  # openai | anthropic | ollama | mock
openai_api_key = "sk-..."
anthropic_api_key = "sk-ant-..."
ollama_base_url = "http://localhost:11434"
context_lines = 10
max_context_chars = 10000

When to Use Tokenectomy:

  • ✅ You use AI coding agents (Claude, Cursor, Cline, etc.)
  • ✅ You care about privacy & local-first processing
  • ✅ You want to reduce LLM token costs
  • ✅ You're worried about secret leakage in logs

When to Use Something Else:

  • ❌ You only need static secret scanning → use truffleHog, detect-secrets
  • ❌ You need real-time monitoring dashboards → use Datadog, New Relic, Splunk
  • ❌ Your error logs are naturally <100 tokens → overhead not worth it
  • ❌ You're fully air-gapped → Actually Tokenectomy is perfect! (100% local processing)

Frequently Asked Questions

Q: Does Tokenectomy send my logs to external servers?

A: No. All redaction, parsing, and filtering happens locally on your machine. The only network call is to your chosen LLM (OpenAI, Anthropic, Ollama) after sanitization is complete. See SECURITY.md for the zero-knowledge guarantee.


Q: What secrets does Tokenectomy redact?

A: GitHub PATs, AWS keys, OpenAI/Anthropic API keys, JWTs, database connection strings (PostgreSQL, MySQL, MongoDB, Redis), private SSH keys, Slack/Discord webhooks, and more. Full list in src/redact.rs.


Q: What if my secret doesn't match the redaction patterns?

A: File an issue with an example (sanitized). We'll add the pattern. For now, you can add custom patterns in ~/.tokenectomy.toml (feature coming in v1.3).


Q: Is Tokenectomy safe for production?

A: Yes. Written in safe Rust (zero unsafe code in security paths), ReDoS-immune, and audited via RustSec. See SECURITY.md for full details.


Q: Can I use Tokenectomy offline?

A: Yes—except Stack Overflow search. Use --local-only flag to disable all network access (except your LLM).


Q: How do I remove Tokenectomy?

A: Simply uninstall:

npm uninstall -g tokenectomy-razor
# OR
cargo uninstall tokenectomy

Zero config cleanup needed—no files left behind.


Q: Can I use Tokenectomy in my CI/CD pipeline?

A: Yes! Use the GitHub Marketplace action (see Quick Start section) or the Docker container. Works with GitHub Actions, GitLab CI, Jenkins, etc.


Q: What's the difference between Razor (OSS) and Sentinel (Commercial)?

A: Razor is the free, community version with all essential features. Sentinel adds advanced capabilities like tree-sitter AST healing, anti-hallucination guards, and time-machine undo. See Edition Comparison below.
