Agent Security and Governance
Running agents without giving away more than you meant to. These pages cover scoped credentials and key rotation, permission boundaries, prompt injection and tool poisoning, sandboxing, data retention, audit trails, and the review process around autonomous output. Fast.io supports this with scoped API keys, granular workspace permissions, encryption in transit and at rest, and an append-only audit log. It is not SOC 2, ISO 27001, or HIPAA certified, and it runs on certified infrastructure partners rather than claiming those certifications itself.
Coverage assumes an agent with real access rather than a demo, so the pages spend their time on blast radius: what a confused or compromised agent could reach, how to shrink that before it matters, and what evidence you would have afterwards. They describe specific controls rather than certifications, and they say which ones are worth putting in place first when you cannot do everything at once.

LiteLLM rate limits define the maximum requests per minute (RPM) and tokens per minute (TPM) enforced on individual users, keys, or upstream provider endpoints within a LiteLLM proxy deployment. When multi-agent systems trigger upstream 429 errors, automated router fallbacks and cooldowns maintain gateway uptime. Connecting agents to an indexed Fast.io workspace via Model Context Protocol retrieves targeted context, cutting payload sizes and preventing token exhaustion.
LlamaIndex Rate Limits: Ingestion Batching, Embedding Quotas, and Offloaded Indexing
LlamaIndex rate limits are API request and token bottlenecks triggered while parsing, chunking, and embedding large file corpora through third-party embedding models. When unthrottled ingestion pipelines process hundreds of documents simultaneously, upstream providers enforce per-minute caps that return HTTP 429 errors. Tuning embedding batch sizes and offloading indexing to intelligent workspaces via remote MCP prevents token exhaustion and stabilizes agent pipelines.
Managing LangGraph Rate Limits, Node Throttling, and State Stores
LangGraph workflows trigger HTTP 429 rate limits when parallel branches and multi-agent graphs exceed upstream provider throughput ceilings. Resolving these bottlenecks requires distinguishing graph recursion bounds from API rate limits, configuring retry policies with backoff, and throttling concurrent node execution. Decoupling document storage from the graph state store prevents checkpoint bloat and token-heavy payload transfers across execution cycles.
Mistral API Rate Limits: La Plateforme Tiers, 429 Errors, and Corpus Retrieval
Mistral API rate limits restrict requests per second, tokens per minute, and monthly consumption across La Plateforme tiers.

OpenAI Rate Limits: TPM, RPM, Tiers, and Large Corpus Strategies
OpenAI rate limits restrict API consumption through Requests Per Minute, Requests Per Day, and Tokens Per Minute across account tiers. Attempting to analyze large document collections by pushing raw file text into prompt payloads quickly exhausts TPM allocations and triggers HTTP 429 errors. Decoupling storage from inference by indexing files in an intelligent workspace and querying them through remote MCP retrieval prevents quota exhaustion while maintaining complete document access.
OpenRouter Rate Limits: 20 RPM Caps, 429 Errors, and Agent Storage Workarounds
OpenRouter restricts free models to 20 requests per minute and 50 to 1,000 requests per day based on credit purchases, while paid models remove platform caps in favor of upstream provider capacity. Most HTTP 429 errors stem from downstream provider congestion rather than gateway throttling. For AI agents, dumping raw documents into prompts accelerates limits. Offloading files to indexed storage prevents redundant requests.
Pinecone Rate Limits: Read Units, Write Units, and Vector Indexing Limits
Pinecone rate limits represent throughput caps expressed in Read Units (RUs) and Write Units (WUs) that constrain how fast an agent can query or upsert vector embeddings. Serverless indexes enforce default throughput ceilings of 2,000 query RUs per second per index and 100 upsert requests per second per namespace, returning HTTP 429 errors when thresholds are breached. Pacing vector pipelines with exponential backoff or indexing files in intelligent workspaces eliminates ingestion bottlenecks.
Roo Code Rate Limits: Token Exhaustion, Provider Quotas, and MCP Workspaces
Roo Code rate limit refers to API rate limits (HTTP 429) hit when Roo Code's multi-step agent modes issue rapid sequential tool calls and large context window re-evaluations. Autonomous agent loops re-reading entire directory trees quickly exhaust RPM and TPM quotas across model providers. Connecting Roo Code to remote Fast.io MCP workspaces lets agents query indexed file context on demand instead of stuffing repositories into active prompt history.
Together AI Rate Limits: 1 RPS Free Caps, Tier Quotas, and 429 Error Fixes
Together AI rate limits restrict requests per second (RPS), requests per minute (RPM), and tokens per minute (TPM) sent to serverless inference endpoints.
