SPF

What it grounds

Ground agents in real-time SPF record data so email-security answers reflect live DNS truth and authorized senders, not assumptions.

Ways to ground with it

Ground security & research agents

Let an agent call SPF to pull a domain's real records or health before it reasons about risk — verifiable signal instead of a confident guess.

Enrich a workflow with real records

Wire spfvalidator into a compliance or research agent so each domain it evaluates is backed by live data it can cite.

Auditable lookups

Every record the agent uses carries SPF as its origin, so findings are traceable.

Connect over MCP

Point your agent framework at the VerveContext endpoint. Every enabled source — this one included — becomes a tool the model can call. No per-source plumbing.

# “spfvalidator” is now a tool your agent can call

Facts your agent can cite

Each call returns structured fields your agent can read — and trace back to this source.

How to ground an agent in it over MCP.

How do I give my agent SPF?

Enable it on VerveContext and point your agent framework at the VerveContext MCP endpoint. SPF then appears to the model as a tool named spfvalidator, which it calls when a task needs it — no per-source plumbing.

Which agents and frameworks can use it?

Any MCP client — Claude, Cursor, LangChain, and custom agents all speak the Model Context Protocol. SPF is exposed as a standard tool, so nothing source-specific is required.

Can the agent cite SPF?

Yes. SPF is verifiable factual grounding — every value the agent pulls can carry SPF as its source, so a person (or another system) can trace where the fact came from.

How many credits does a SPF call cost?

Each call costs 5 credits. Scoped keys let you grant an agent only the sources it should reach, and usage logs show exactly what was pulled to ground each answer.

How current is the data?

SPF is served live from APIVerve's production data engine and pulled at the moment the agent calls it, so answers reflect the world now rather than the model's training cutoff.

Where does the data come from, and what shows on my bill?

VerveContext runs on APIVerve, our production data engine; SPF is one of 300+ sources on the same key. Invoices and card statements show APIVERVE.
