Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00000 | $0.00459 |
| Opus 5 | $0.00000 | $0.00230 |
| Sonnet 5 | $0.00000 | $0.00092 |
| Haiku 4.5 | $0.00000 | $0.00046 |
Grade A, and why
langgraph scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
LangGraph Integration with ContextForge
LangGraph is a framework for developing applications powered by language models. Integrating LangGraph with the Model Context Protocol (MCP) allows agents to utilize tools defined across one or more MCP servers, enabling seamless interaction with external data sources and services.
🧰 Key Features
- Dynamic Tool Access: Connects to MCP servers to fetch available tools in real time.
- Multi-Server Support: Interact with tools defined on multiple MCP servers simultaneously.
- Standardized Communication: Utilizes the open MCP standard for consistent tool integration.
🛠 Installation
To use MCP tools in LangGraph, install the langchain-mcp-adapters package:
pip install langchain-mcp-adapters
🔗 Connecting to ContextForge
Here's how to set up a connection to your ContextForge:
from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
client = MultiServerMCPClient(
{
"gateway": {
"url": "http://localhost:4444/mcp",
"transport": "streamable_http",
}
}
)
Replace "http://localhost:4444/mcp" with the URL of your ContextForge.
🤖 Creating an Agent
After setting up the client, you can create a LangGraph agent:
agent = create_react_agent(
tools=client.get_tools(),
llm=your_language_model,
)
Replace your_language_model with your configured language model instance.
🧪 Using the Agent
Once the agent is created, you can use it to perform tasks:
response = agent.run("Use the 'weather' tool to get the forecast for Dublin.")
print(response)

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

langgraph is an agent published in the GitHub repository IBM/mcp-context-forge (4,399 stars, last pushed today), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 459 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

Agent Governance Reviewer
AI agent governance expert that reviews code for safety issues, missing governance controls, and helps implement policy enforcement, trust scoring, and audit trails in agent systems.
chat-agents
Build AI-powered chat interfaces with AIChatAgent and useAgentChat. Messages are automatically persisted to SQLite, streams resume on disconnect, and tool calls work across server and client.
callable-methods
Callable methods let clients invoke agent methods over WebSocket using RPC (Remote Procedure Call). Mark methods with @callable() to expose them to external clients like browsers, mobile apps, or other services.
webhooks
Receive webhook events from external services and route them to dedicated agent instances. Each webhook source (repository, customer, device) can have its own agent with isolated state, persistent storage, and real-time client connections.
