SourceryKitMake every agent answer
State of the art tools that automatically verify agent tool calls at runtime. Run accurate, safe and reliable agents and critical workflows in minutes.
100% error detection rate
Agents self verify to produce proofs that their answers came from the right source and were not changed, increasing reliability and security.

Up to 50% higher agent accuracy
Proofs let downstream agents catch hallucinations or wrong source data without re-querying sources. Agents retry and self heal.
Ship reliable agents in minutes
Add the SourceryKit SDK in minutes and verify across agents, tools, and networks without complex tracing or cross-team setup.
$ pip install sourcerykit
Performance
Verify Now. Learn Continuously.
Traditional observability needs failures, traces and classification before teams can improve agents. SourceryKit verifies answers and detects errors in real time, powering faster evals and continuous learning loops.

Faster
Automatic failure signals
Every run produces a clear pass, caught or error outcome without manual trace classification.
Better eval data
Feed deterministic, evidence backed results into evals instead of relying only on model judges.
Verifiable rewards
Turn verified tool outcomes into trusted reward signals for training and continuous improvement.
Integrations
Built for your existing tools
Connect SourceryKit to your existing stack and every agent interaction becomes verifiable. Every API call, database query, and MCP server interaction is intercepted and turned into a proof downstream agents can verify in milliseconds.
Use cases
Where errors are not an option
Customer service agents
Customers get answers they can trust, grounded in verified account, order and policy data.
Security operations and AI SOC
Verifiability lets teams depend on agent operations during critical investigations, even when the full extent of an attack is still unknown.
Healthcare and finance workflows
Verify agent tool calls in payment and patient systems before agents act.
Cross agent communication
Verifiability enables accurate, safe cross organisational A2A workflows that teams can operate with confidence.
Least privilege verification
Verify agent operations when original source systems or raw logs are inaccessible.
AI governance and compliance
Create machine verifiable audit trails for EU AI Act reporting, internal controls and independent audits.

Searches you can verify
AI answers can be fabricated, or cite sources that lead nowhere. Verifiable Search adds SourceryKit to a search engine, so you can check any claim against the text it came from.
