FreshContext
I asked Claude to help me find a job. It gave me a list of openings. I applied to three of them. Two didn't exist anymore. One had been closed for two years.
Claude had no idea. It presented everything with the same confidence.
That's the problem freshcontext fixes.
This repository is the integrated FreshContext Core/MCP package. FreshContext is the context judgment layer between retrieval and reasoning. Core is the reusable engine that scores, ranks, explains, and turns candidate context into decision-ready context; MCP is the first live host/interface over that engine.
Live demo: freshcontext-mcp.gimmanuel73.workers.dev/demo — same model, same query, two completely different answers. Only the temporal layer changed.
The problem
Large language models retrieve web data semantically. Cosine similarity finds the documents that match a query best — but cosine doesn't know when a document was written.
So a 2022 blog post and a 2026 paper can score nearly identically. The model gets a context window full of stale documents and faithfully summarizes 2022 advice for a 2026 question.
That's not hallucination. That's correct summarization of corrupted retrieval.
Most RAG pipelines rank context correctly semantically but incorrectly temporally.
The layer
FreshContext is context integrity infrastructure for AI agents and retrieval systems. It sits between retrieval and reasoning:
candidate context
-> FreshContext Core
-> decision-ready context
-> model / agent / appFreshContext evaluates freshness, source profile, confidence, utility, provenance material, and failure honesty before context reaches the LLM. The temporal core uses Decay-Adjusted Relevancy:
R_t = R_0 · e^(−λt)R_0— base semantic relevancy (whatever your retriever already gives you)λ— source-specific decay constant (HN ≈14h half-life, blogs ≈29d, academic papers ≈1.6y)t— hours elapsed since publicationR_t— decay-adjusted relevancy at query time
That's the core correction. No model swap. No re-embedding. No re-indexing. The layer drops onto whatever retrieval pipeline you already have.
The layer is the product. The named adapters shipped with this repo demonstrate compatibility across different source classes. The DAR engine, the freshness envelope, Source Profiles, and the FreshContext Specification are the moat.
The standard
Every FreshContext-compatible response wraps content in a structured envelope:
[FRESHCONTEXT]

Confidence: high

... content ...
[/FRESHCONTEXT]When it was retrieved. Where it came from. How confident we are the date is accurate.
The FreshContext Specification v1.2 is published as an open standard under MIT licence. Any tool, agent, or system that wraps retrieved data in this envelope is FreshContext-compatible. → Read the spec · Read the methodology
Architecture boundary
FreshContext Core is the reusable center of the current integrated package. It owns signal normalization, freshness scoring, Source Profiles, decision output, envelope formatting, failure guards, shared types, rank/explain primitives, and the context-conditioned utility primitive.
MCP is the primary reference/interface implementation over Core. Claude Desktop is supported, but not required. The MCP tool surface exposes named reference adapters and a live interface for using the system.
The production Cloudflare Worker now uses Core-backed envelope generation. Worker-specific concerns remain outside Core: MCP transport, runtime guards, KV cache policy, cache metadata injection, JSON parse/replace cache helpers, D1 feeds, cron, rate limiting, and Store/feed scoring/provenance.
See Core / MCP Boundary for the current package boundary and the staged path toward a future standalone Core package.
Primary MCP interface
The clearest MCP path is evaluate_context.
It accepts candidate context from any retriever, agent, database, local script, note parser, or adapter output:
{
"profile": "academic_research",
"intent": "citation_check",
"signals": [
{
"title": "Example source",
"content": "Candidate context text...",
"source": "https://example.com/source",
"source_type": "arxiv",
"published_at": "2026-05-24T12:00:00.000Z",
"retrieved_at": "2026-05-24T13:00:00.000Z",
"semantic_score": 0.92
}
]
}FreshContext returns decision-first output:
- Decision
- Meaning
- Action
- Warnings
- Source
- Freshness
- Rank score
- Utility
- Confidence
- Why
evaluate_context does not fetch URLs, crawl, scrape, browse, read folders, or call adapters. It only evaluates candidate context the caller provides.
Current boundary: evaluate_context is part of the published npm/local stdio MCP server. The hosted Cloudflare Worker endpoint is a separate deployment surface and may lag npm package interfaces until a dedicated Worker sync pass.
Advanced Worker/feed surface
Beyond the per-call Core/MCP paths, the production Worker deployment exposes a continuous, decay-scored, deduplicated feed. This is an advanced deployment surface, not the required way to use FreshContext Core:
GET /v1/intel/feed/:profile_id?limit=20&min_rt=0Every signal is stamped with base_score, rt_score, entropy_level (low / stable / high), ha_pri_sig (Ha-Pri v1 SHA-256 provenance reference), semantic_fingerprint (cross-adapter dedup), and published_at. Ready for direct LLM or agent consumption — no synthesis required.
Production endpoint: https://freshcontext-mcp.gimmanuel73.workers.dev
Reference adapters
The repo ships named reference adapters that demonstrate how different source classes can become FreshContext-compatible. Each adapter keeps its own name because it represents a source boundary; the adapter count is operational proof, not the product headline.

The npm run demo:* commands below are source-checkout workflows for contributors and evaluators using a cloned repository. The published npm package is the MCP server/runtime package and does not include repo-only source examples or tests.
From an installed npm package, the supported runtime entrypoints are npm start and the freshcontext-mcp binary. Repo-only scripts such as tests, demos, smoke checks, and trust scans print a source-checkout notice when their source files are not present.
The Apify Actor entrypoint remains available in the source checkout for separate actor packaging, but it is intentionally not part of the published MCP npm runtime package.
Release trust gate
Run the local release gate before a release, package review, demo, or PR review:
npm run trust:gateThe gate runs the Trust Scanner with repo-map reporting, npm package-boundary inspection, deterministic claim checks, and --fail-on fail. It is local-only, does not publish or deploy, does not send telemetry, and does not replace dedicated security scanners.
Generate review reports when you need a shareable summary:
npm run trust:report
npm run trust:report:jsonTo write a Markdown report file explicitly:
npm run trust:report -- --output TRUST_SCAN_REPORT.mdBring your own source list
FreshContext can evaluate candidate context you provide as a local JSON file:
npm run demo:evaluate:fileTo pass a different file:
npm run demo:evaluate:file -- path/to/sources.jsonIncluded examples:
npm run demo:evaluate:file -- examples/sources.academic.example.json
npm run demo:evaluate:file -- examples/sources.jobs.example.jsonMinimal shape:
{
"profile": "academic_research",
"intent": "citation_check",
"signals": [
{
"title": "...",
"content": "...",
"source": "...",
"source_type": "arxiv",
"published_at": "...",
"retrieved_at": "...",
"semantic_score": 0.92
}
]
}This local demo does not fetch URLs, crawl, or read folders. It evaluates candidate context you provide and returns decision-first output: Decision, Meaning, Action, Warnings, and supporting metrics.
In an MCP client, use evaluate_context when you already have candidate context from another retriever, database, agent, or script:
Use evaluate_context with profile "academic_research", intent "citation_check", and these candidate signals: [...]Use the named reference adapters when you want FreshContext's current MCP package to fetch public source examples for you.
Should I build this idea?
Use extract_idea_landscape with idea "procurement intelligence saas"Returns funding signal, pain signal, crowding signal, market signal, ecosystem signal, and launch signal — all timestamped.
Full company intelligence in one call:
Use extract_company_landscape with company "Palantir" and ticker "PLTR"SEC filings + federal contracts + global news + changelog + market data.
Did that company just disclose something material?
Use extract_sec_filings with url "Palantir Technologies"8-K filings are legally mandated within 4 business days of any material event — CEO change, acquisition, breach, major contract.
Is this dependency still actively maintained?
Use extract_changelog with url "https://github.com/org/repo"Returns the last 8 releases with exact dates. If the last release was 18 months ago, you'll know before you pin the version.
Deployment & infrastructure
The reference implementation runs on Cloudflare's global edge:
| Endpoint | Method | Purpose |
|---|---|---|
| / | GET | Service info + endpoint list |
| /health | GET | Liveness check |
| /mcp | POST | MCP JSON-RPC transport |
| /demo | GET | Live before/after demo (no API key required) |
| /briefing | GET | Latest stored briefing |
| /v1/intel/feed/:profile_id | GET | DAR-scored intelligence feed |
| /watched-queries | GET | List all watched queries |
- D1 database — 18 watched queries running on 6-hour cron with relevancy scoring
- KV-backed rate limiting — 60 req/min per IP across all edge nodes
- Defensive valves — clock-skew rejection (5min tolerance), hard floor at R_t<5, lazy decay at read time
- Provenance — Ha-Pri v1 SHA-256 provenance stamps on stored signals; hard tamper enforcement is a future Ha-Pri v2 path
- Schema migrations — promise-gated, idempotent, run on first request after deploy

Contributing
PRs welcome. The highest-value contributions improve the caller-provided context path, decision output, host integrations, and FreshContext-compatible signal quality. New reference adapters are useful when they preserve source boundaries and emit timestamped, failure-honest context — see src/adapters/ for examples and FRESHCONTEXT_SPEC.md for the compatibility contract.
If you're building something FreshContext-compatible, open an issue and we'll add you to the ecosystem list.
